If I ignored the dishes, I’d feel a little like I had a personal breakfast chef.

I discovered this method for cooking steel-cut oats in the crock pot the year a series of unfortunate events left us without a stove for almost three months.

I’ll spare you the details, but suffice to say that without a proper cooktop or oven, I embraced my slow cooker with a passion I didn’t realize I could muster for an appliance.

I’d seen overnight steel cut oatmeal recipes floating around the web for ages, but most were for the cold variety that soaks overnight in the refrigerator. (Check out my version of Overnight Steel Cut Oats!)

While I do adore regular overnight oats (these Apple Cinnamon Overnight Oats and this Sugar Cookie Overnight Protein Oatmeal are two favorites), in the winter months, I crave my oatmeal hot.

The issue: On weekday mornings, I’m usually too busy or too unmotivated to stand at the stove and wait for steel cut oatmeal to simmer. My priorities are coffee and finding a pair of socks that match.

The solution: Slow Cooker Steel Cut Oats!

The Miracle of Overnight Slow Cooker Steel Cut Oats

If you’ve never had steel cut oats, prepare yourself for a serious oatmeal upgrade.

Steel cut oats (whole oats that have been cut into a few pieces) are significantly less processed than instant oats, which are steamed, pressed, ground, and otherwise obliterated.

This means that, unlike instant oatmeal, which has all the flavor and texture of a pile of wet sawdust (oatmeal skeptics, I can sense your nods of understanding), steel cut oatmeal has a hearty, pleasing texture and nutty taste.

As a bonus, because steel cut oats take your body longer to break down, they keep you fuller too.

The one downfall of steel cut oats is that, if you make them day of, they can take 30 minutes or longer to cook on your stovetop, which is about 26 minutes longer than I’m willing to wait for my breakfast on an average morning.

Making overnight steel cut oats in the slow cooker solves the problem. All of the steel cut oatmeal magic happens in the slow cooker overnight, so in the morning, the only waiting you’ll do is for the coffee to brew. (Another example of overnight recipe magic: Crockpot Egg Casserole!)

To give my banana bread overnight steel cut oats some pizzazz, I took inspiration from my favorite healthy banana nut muffins, adding mashed ripe bananas, cinnamon, and nutmeg to the oats before they cooked. The result was a filling, healthy breakfast with the cozy flavor of freshly baked banana bread.

Going along with the Slow Cooker Steel Cut Oats banana bread theme, I couldn’t stop myself from topping my bowl with extra banana slices and walnuts. Combined with the bananas that were mixed into the crock pot oatmeal, this steel cut oats recipe has just the right amount of sweetness for me.

If you prefer your oatmeal on the sweeter side, I suspect a drizzle of pure maple syrup or honey will do the trick. Chocolate chips and a giant dollop of peanut butter wouldn’t hurt either.

For those who prefer to keep the overnight Slow Cooker Steel Cut Oats plain, you can swap the mashed banana for unsweetened applesauce or a few extra splashes of milk to ensure they do not dry out.

Tips for Slow Cooker Overnight Oats Success

  • Either be VERY generous with the nonstick spray or use a crock pot liner. Steel cut oats like to stick.
  • Use regular, long cooking steel cut oats like these ONLY. Any other kind of oatmeal (including quick-cooking steel cut oats, regular rolled oats, quick oats, and the aforementioned instant oatmeal) can’t stand up to the hours in the slow cooker and will degrade into total mush.
  • Every slow cooker is different. If your slow cooker runs hot or does not have a function to switch to “off” or “keep warm” after the cooking time is through, you risk overcooking or even burning the edges of the steel cut oatmeal. If this is the case, my suggestion is to make the slow cooker steel cut oats during the day when you can keep an eye on it, and then reheat it the next morning. This guarantees perfect crock pot oatmeal, and you still have the make-ahead benefit.
  • Hack if you are REALLY worried about the edges burning: stir together the steel cut oatmeal ingredients inside a large casserole dish that will fit inside your slow cooker. Pour a little water in the bottom of the slow cooker, and then place the dish inside (the water should go about halfway up the side of the dish). This creates a water bath and allows a longer cook time.

How to Store Leftover Oatmeal

This recipe makes a big batch of slow cooker oatmeal, which I guarantee you will be happy to have on hand.

  • You can store leftover overnight slow cooker steel cut oats in the refrigerator for almost a week, and in the freezer for months. To reheat, simply mix your desired portion of steel cut oats with a little water or milk and warm it in the microwave.
  • For meal-prep ease, I also like to freeze my leftover crock pot oatmeal in portioned containers and place a few in the refrigerator to thaw at the beginning of each week. I love waking up knowing that I’m just a few minutes away from a warm, healthy bowl of steel cut oatmeal, with no work beyond lifting my spoon required.

Overnight Slow Cooker Steel Cut Oats with Banana

Yield: 6 servings
Prep Time:
10 mins
Total Time:
8 hrs
Overnight slow cooker steel cut oats that cook while you sleep! With banana, cinnamon, and warm spices, this easy crock pot oatmeal tastes like your favorite banana bread. Just put the ingredients in your slow cooker and in the morning, breakfast is served!


  • 1.5 cups steel cut oats — do not substitute quick cooking, instant, or rolled oats, gluten free if needed
  • 4 cups water
  • 2 cups milk — any kind you like (I used skim)
  • 2 large mashed ripe bananas — plus additional banana slices for serving
  • 3 tablespoons ground flaxseed meal*
  • 2 teaspoons pure vanilla extract
  • 1 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon  freshly grated nutmeg  — it's an amazing flavor upgrade to grate your own nutmeg. I use this zester to do it.
  • 1/2 teaspoon kosher salt
  • For serving: chopped toasted walnuts — raisins, chocolate chips, maple syrup, peanut butter, or any other mix-ins you enjoy with banana bread


  1. Place all of the ingredients except the toppings in the bottom of a 4-to-6-quart slow cooker and stir to combine: Steel cut oats, water, milk, mashed bananas, flaxseed meal, vanilla, cinnamon, nutmeg, and salt. Cover and cook on low for 7-8 hours (overnight) or on high for 4 hours, until the oats are soft but maintain a bit of chew. Remove cover and stir to evenly combine the ingredients. Enjoy warm with desired toppings.

Recipe Notes

Overnight steel cut oats can be refrigerated for up to 1 week or frozen for up to 2 months. To reheat, top desired amount with a few tablespoons of water or milk, then warm in the microwave or in a small saucepan until hot. If the oatmeal is frozen, let thaw overnight in the refrigerator first.
*The ground flaxseed meal I added for a nutritional boost. If you don't have it or do not wish to add it, simply omit it. You can also substitute chia seeds or hulled hemp seeds.

  1. I just got on the slow-cooker overnight oats train about three weeks ago myself, and holy moly it’s  game changer. Nothing like waking up to hearty oats waiting for you (and that smell!!!) Can’t wait to try your version – bananas sound heavenly! 

  2. I need more of these recipes in my life! I am a BIG fan of anything banana bread flavored! Also, I wanted to tell you that I was thinking of you yesterday when you posted about your father’s birthday. Just know that his love will continue to shine through you. Love you friend! 

  3. Believe it or not, I JUST came into possession of a slow cooker thanks to project cohabitation :) And I’ve been dying to try overnight steel cut oats! Also, your new dark wood backdrop is totally dreamy. 

  4. hey girl this would be fabulous!!

  5. I can swap out the milk for a non dairy version?

    • Definitely Angela! You can use any kind of milk (dairy or non dairy) that you like.

    • Hello!
      I’ve been eating this recipe every morning for almost 3 weeks now. I first made it with coconut almond milk in place of the milk, the second time I replaced th he milk entirely with water. The taste is still full, and lost no “mouth feel” as my husband says. Very forgiving recipe. Whenever I’ve made the recipe without milk or butter I’ve upped the amount of cinnamon and vanilla.

      I’ve played around with this recipe a great deal, always using the core ingredients, but I found I’m able to throw handfuls of dried cranberries, whatever raisins, nuts, and even a couple of diced up Granny Smith apples.

      • I’m so excited to hear this Cynthia! Thanks so much for sharing your review and all of the different ways you’ve customized the recipe. It’s so great to read and helpful for others too.

    • We tried it with soy milk and it was awful. Had to be thrown out. So maybe some non-dairy milks would work but I wouldn’t recommend that one. We are making it again tonight with whole milk!

      • Thanks for reporting back, Renee. I’m sorry to hear your experiment with soy milk was unsuccessful! I hope you love the next batch.

  6. Hi Erin, this looks so good – I want some right now!!  Hubbybwas just asking for a batch of oatmeal…we’ll give your a try!

  7. I love slow cooking steel cut oats! It’s the best way to eat them. Great recipe, dear!

  8. I love the taste of steel cut oats the best, but like you said, aint nobody got patience for them in the morning!  I love that I can wake up to the delicious smell of banana oatmeal and not have to actually make a mess in the kitchen!  This recipe is da bomb :)

  9. I’d definitely take you up on that chocolate and peanut butter addition! Something about that Elvis combo of banana, chocolate, and PB is just irresistible :)

  10. This looks fantabulous, my dear! I might not be able to enjoy it sadly on account of the bananas, but I do know the wee one and the husband would devour it for days!

  11. I completely agree with you on steel cut oats. While I love oatmeal. I find steel cut oats, with their nutty bite, far more enjoyable. Plus the slow cooker method rocks. I used to stand at the stove stirring adn sitrring. We enjoyed every bite, but the standing and stirring got old, and so did I. Then I discovered the oven-method – from Marion Cuinningham, I think. From there it was a short hop to the (as we used to call it) the crock pot. What a great method. I love your additions of flaxseed and spices. These sound wonderful. Eat your oats!

  12. I love having overnight oats for weekday breakfasts! The banana bread flavor sounds so good!

  13. Always looking for a great overnight oats recipe; the banana bread flavor sounds amazing; looking forward to making it :)

  14. I made this last night.  I was a little underwhelmed when I found that it had stuck to the pot and was pretty bland.  A little coconut oil would prevent the sticking and add richness.  I added some to my serving and it was great.  Also, I know many people like to sweeten their oatmeal after serving, but I have an 8 yr old who serves herself.  She is not allowed to add sugar, honey, maple syrup, candied ginger or banana chips on her own.  I learned my lesson long ago.  I added a little brown sugar (I only needed 2 Tablespoons for the whole pot) and she loved it.  We are taking this recipe to the slopes next weekend.  It’s perfect for bunch of skiers!

    • Carolyn, I’m sorry that this flavor didn’t hit the spot for you exactly as written, but I’m glad that coconut oil and brown sugar did the trick. That sounds fabulous! Enjoy it on your ski trip too. That sounds like a fun trip, and I love that this recipe will be coming along with you!

  15. I made this last night, too.  I have kids so I added a little brown sugar.  The flavor was very good, but the texture was pretty gloopy.  Much of the oatmeal ended up dark brown and stuck to the sides of the slow cooker.  I was hoping for a little more chew to the oats.  Just hard to adjust cook time when you’re sleeping :)

    • DJ, I’m sorry you had trouble with the oatmeal sticking! I didn’t run into that, but I did a bit of reading and discovered a method for preventing it—mix the ingredients in a large, heatproof casserole dish that fits inside of your slow cooker. Then, fill the slow cooker with enough water to come half way up the sides of the dish, gently place the dish inside, and cook the entire thing in a water bath. I hope that helps! I plan to test the recipe that way next time myself. Does your crock pot have an automatic off switch? Setting the timer for less time may help with the texture too. 

  16. I’d love to try this but wondering if there is something I could substitute for the ground flaxseed meal? Thanks! 

    • Hi Alisha! You can simply omit the flaxseed meal or swap it for another “super food” mix-in ingredient like hemp seeds or chia seeds. I hope you enjoy the recipe!

  17. I made this last night with a couple of variations from previous posters. I added 1 tbsp of coconut oil and 2 tbsp of brown sugar. It turned out so good!! I’ve added a small amount of raisins, chocolate chips and sunflower butter as a topping and it’s just perfect! Thank you!!

    • Lindsay, I am so excited to hear this! Thanks for letting me know and sharing your tips for others making the recipe too.

      • You’re welcome! Had leftovers this morning and they heated up with a bit of milk perfectly. I used just raisins this time and it was just as tasty. Will definitely be making this one again! Thanks Erin!

  18. Sadly, I read this and realized you cannot use quick cook steel cut oats! If I do, would you have any suggestions as how to modify the recipe? 

    • April, if you want to use quick cooking, I would suggest cooking them on the stovetop according to the package instructions. You can always mix in the mashed banana and spices to create a similar effect. Unfortunately, quick cooking oats will turn to goo in the slow cooker. The other option would be to try reducing the cooking time significantly, but since I’ve never tried this recipe with quick cooking oats, I can’t give you an exact time.

  19. Thanks for the suggestion, that’s just what I did this morning and my son and I loved it! 

  20. Have you ever tried this w/ dried bananas? Bananas don’t last long in my house, but I do have a bag of bananas I dehydrated myself.

    • Anna, I haven’t so I can’t say for certain how that would turn out. The ripe bananas add both moisture and sweetness to the oatmeal, so the final result would definitely be different. The dried bananas won’t mix in with the oats the way ripe, mashed bananas do. I’d suggest starting with mashed bananas, then decide how you’d like to customize the oatmeal from there!

  21. I’m trying to work with some gluten free rolled oats I have (I see that it says not to substitute these). I’m new to the slow cooking game, cooking in general if I’m honest, so is there any particular reason for not using rolled? Is it just a texture thing, or will the taste be wrong? I really wanna try out this recipe

    • Hi Sarah! Rolled oats won’t work for this recipe because they have such a short cooking time, they’ll turn to total goo if left in the slow cooker overnight.  If you want to use rolled oats, I would suggest cooking them on the stovetop according to the package instructions. You can always mix in the mashed banana and spices to create a similar effect. Unfortunately, quick cooking oats will turn to goo in the slow cooker. The other option would be to try reducing the slow cooker time significantly, but since I’ve never tried this recipe this way, I can’t give you specifics. I hope you are able to find a way to make this recipe work for you!

  22. Do you think you could double or triple this recipe for a large group in a standard sized crockpot?

    • Hi Chelsea! I’ve never tried this recipe doubled or tripled—my guess is that you would be safe with doubled, but I’m not sure about tripled. Big batches of things can sometimes not cook the same way. If you need a really, really big batch, perhaps you could borrow a slow cooker from a friend and have two batches going at the same.

  23. This recipe essentially was my introduction to steel-cut oats, and I was looking for something–like you–that didn’t take forever and a day when I wanted something fast. I liked the efficiency it provided but might adjust upwards the “banana bread” components to get more of that flavor–especially the bananas. I really like the way it reheats–thank you for the tip on adding milk/water during the reheating to help loosen it up. 2 T (milk) added to one cup of the final product, then heated on high for 3 minutes (stir after two) seemed to be a good combination for me.

    Thank you!

  24. Just curious, what’s wrong with rolled oats?

    • Hi Rick! Please see the answer to Sarah’s question above—essentially, because rolled oats cook more quickly, they will turned to mush in the slow cooker. Steel cut is the way to go.

  25. Tried this last night for the first time and was disappointed with the texture… I’ve been eating steel cut oats for a while and didn’t expect them to turn so “mushy” in the slow cooker. The flavours were great, but the texture definitely was not. I followed the directions, using 4 cups of water and 2 cups of 1% milk. I had it on low for 8 hours. Would you have any suggestions to improve the texture? Less liquid? Doing the 4-hour version on high? I really like the flavour so I would like to make this work! Thanks

    • Hi Isabelle! This sounds like the oats overcooked. Every slow cooker is different, and yours might be extra powerful. I would try cooking it for less time that specified in the directions (for either low or high heat) and see how that goes. You could also skip the slow cooker entirely and make the oats on the stovetop with milk (use a little less liquid than the amount specified on the package since you’ll be adding mashed bananas), and the other recipe ingredients (mashed bananas, spices, vanilla, etc.). I hope it goes better for you the next time!

    • I too tried this last night with the same measurements of oats, milk, and water, and unfortunately I had the same mushy result. When I originally combined the ingredients, my husband and I agreed that we probably should have used two cups of oats and half the amount of water. However, we decided to trust the recepie and take it from there. Next time we will try more oats and less water. We love using our slow cooker and loved the idea of this warm, cozy breakfast. We do have a more basic cooker without the bells and whistles, but I’m sure it works all the same :) 

      • Hi Hannah, I’m sorry to hear you experienced the same result. Every slow cooker seems to behave differently, so the amount of time needed to get the right texture can really vary depending on your model! If you do try less liquid, I’d love to know how it comes out.

      • Hi Hannah! I accidentally set my crock to warm instead of low and they came out perfect! I think mine would have been overcooked had I not had this happy accident. You might want to give it a try!

  26. Cynthia A Kaler Reply

    I ate this again this morning and have everyone at work questioning me about what I’m eating and how can I eat it every single day? This banana recipe is wonderful, I don’t remember ever eating the same food every day before but each time I have my oats they still “taste great and no desire to eat something else”. You know your hooked when you pass up the donuts at work, and other junk food. I’ve also noticed I eat a great deal less during the day since I started eating this recipe for breakfast. I’m up at 5:30 every single day, eat my banana oats around 8 .I graze on it all morning at my desk at work, I eat nothing else..no coffee break snack, and most days I find its 3:00 and I’ve forgotten to eat my lunch. My clothes are fitting better, less muffin top. :)

    • Cynthia, I am so so happy that you love this recipe so much! I get the same way about oatmeal myself. It’s also wonderful to hear how filling this is and that’s it helped you make positive healthy changes. HOORAY! Thank you so much for letting me know and taking time to leave this kind review. It truly means a lot!

  27. I just made this last night, but instead of using my slow cooker, I used the stove-top method. I brought the water/milk to a gentle boil, added the oats and brought them to a rolling boil. Once at a rolling boil, I reduced to a simmer and added the spice mixture. After about 20 minutes, I added the mashed banana and vanilla. After 10 more minutes I pulled the pot off the stove and let the oats sit until they reached room temp so I could place in the fridge. I had a bowl this morning and it was perfection! I only added 1tsp of light brown sugar to my serving this morning. Thanks so much for this wonderful recipe. The spices were just right and the bananas added perfect sweetness.

    • Ashley, I am so excited to hear that you enjoyed these flavors so much! Thanks for sharing your tips to cook the oats on the stovetop—I know it will be useful for many. Enjoy!

  28. I left the flax out because I didn’t have any and my oats are a soupy mess. I followed the recipe to the T and even let it cook on low for 8 and 1/2 hours. Should I have added more oats to compensate for the flax?

    • I’m so sorry this didn’t turn out for you! While some readers have had the oats turn mushy due to overcooking (every slow cooker is a little bit different, so as with all slow cooker recipes, it’s important to be familiar with how quickly yours finishes food), soupiness has not been an issue. I do think that omitting the flax was part of it—next time you can add extra oats. Also, are you sure you used traditional (not quick cooking) steel cut oats and not old fashioned or quick oats? This recipe is designed to work with steel cut oats only.

  29. Just made this and it was fantastic!! So happy with the results. Doesn’t even need brown sugar for me!! I wanted to eat the whole pot!

  30. Could you state what the serving size for the calories you posted above? 

  31. I made this last night and the only changes I made were adding 1 T. coconut oil and 2 T. brown sugar. And the only problem was that it smelled so good while it was cooking that it actually woke me up at 4am lol :) It was really good and super filling! I’ll be making this again for sure! Thanks for sharing such a great recipe.

  32. Love steel cut oats but, like everyone else, I hate that they take so long to cook. Who has time for that in the madness that is most weekday mornings!?!?  Add the banana bread inspired flavors to cooking the steel cut oats overnight in the slow cooker and I’m in banana oatmeal heaven.  You are this week’s kitchen shortcut hero, Erin!  

    • Agree with you on the time it takes to make steel cut oats Cat! I hope this recipe does the trick for you.

      • I’ve been eating this oatmeal for breakfast all week!  It is so delicious and filling.  My favorite toppings have to be the peanut butter (homemade honey roasted PB) and chocolate chips with sliced bananas, though sliced banana and raw honey came in a close second.  Thanks for the reheating tip, that tablespoon of milk made all the difference.   Just put on a pot for next week.  I want to thank all the reviewers for the coconut oil and brown sugar suggestions.  With 2 T of each added in I didn’t have a problem with the oats sticking to the crock and the level of sweetness was just right considering all sweets I use for toppings :). Dessert for breakfast. Yum!

  33. im making this,tonight. I used coconut almond milk, do fingers crossed. I also used crock pot liner, so hopefully wont stick.

  34. I made this, it was wonderful! I would definitely recommend using a crock pot liner for easy cleaning up. No mess at all!

  35. I’m going to make this tomorrow morning for breakfast. I know from sad experience that nothing can redeem overnight steel cut oats from my slow cooker. It must be super hot.  I’ve figured out that If I soak the oats overnight, they take just a fraction of the time they normally require on the stove. I’m sure they won’t be quite the same as your overnight oats are but I’ll never know and ignorance will be bliss! ?

    • Hi Kathrina, it’s true…slow cookers can vary so much. It’s a bummer you had to find out from experience. The soaking tip is awesome; thank you for sharing! I hope you enjoy!

    • I love this! It’s like eating dessert for breakfast. I think I would really like it with whipped cream on top! ;-) I made it on the stove after letting the oats soak in the liquid ingredients overnight. I added the mashed bananas and ground flaxseed just before cooking. It took about 20 minutes on the stove but that’s okay – gave me time to wrassle the kids, set the table, and find more milk!

      4.5 stars!

  36. Thank you for this recipe!!! I just made it last night and had some for breakfast today. The only things I didn’t add were the flax seeds or nutmeg since I didn’t have any on hand. I substituted extra cinnamon for the nutmeg and extra oats for the flax, sprayed the bottom of my crock pot with coconut oil and used unsweetened vanilla almond milk- cooked it on low for about 7 hours and it was perfect!!! I had no issues cleaning out my crockpot and the consistency was fine. I added a small dash of honey and a few walnuts to the top- I’m still full and look forward to eating it tomorrow and the rest of this week now. :)

    • Hi Jen! I’m so glad you enjoyed the recipe! :) Thanks for sharing your steps and substitutions and toppings! It sounds like a delicious bowl. I really appreciate your taking the time to leave this wonderful review!

  37. This was AMAZING! SOOO yummy. I skipped the cinnamon and the nutmeg but added 1 heaped tbsp. of honey and 1/2 cup milk chocolate chips after stirring it well. One last stir for the chocolate chips then didn’t touch it again so the chips would stay somewhat formed.

    Serving it I put on a tiny bit of brown sugar, a handful of chocolate chips, toasted walnuts and thinly sliced bananas and it was incredible!

    I had it on for more than 8 hours though as I slept in but the texture was fine. It sat for about an extra hour just keeping warm.

    • Hi Sarah, thanks so much! I’m happy to hear you enjoyed the recipe! The chocolate chips sound delicious. Thank you for leaving this awesome review!

      • Had it again today. Just as good too! I didn’t need the brown sugar. Just tossed on a few more Chipits milk chocolate chips, banana and those toasted walnuts, which I just fried up in the small fry pan till roasted. The walnuts not only added nutrition but some great flavour! Between those and the chocolate, it gave me my milk chocolate fix without a big hit of calories! Leaving out the nutmeg and cinnamon with these made this an entirely new taste experience. Let me know if you ever try it. Super tasty way to get chocolate in a modest way!

  38. This was my first time making steel cut oats, and I will definitely make this recipe again! It was a delicious way to use up ripe bananas and the steel cut oats a friend of mine gave me after she purchased them by mistake. Her loss, our gain! This makes mornings much easier too. I did it just like the recipe states. Very good…so good, in fact, that my two-year-old daughter requested more! Definitely a keeper!

    • Hi Beth! Welcome to the world of steel-cut oats! I’m so glad to hear you enjoyed the recipe and that it’s now a keeper for your family. Thank you so much for leaving this wonderful review!

  39. Awesome, Kathrina! I’m so glad you enjoyed the recipes! Thanks for taking the time to report back and let us know how everything went. :)

  40. Hi there! I tried this and it smelled so good cooking! However, in the morning, it was so soupy! It just seemed wrong and looked nothing like the photo. Is it really this much liquid to only 1.5 cups oats? Help!

    • Hello! Yes, the liquid amounts are correct. It sounds like an error with measuring or perhaps the type of oats used. It’s important that they are regular steel-cut oats (not old-fashioned oats or even quick-cooking steel cut).

    • I had the exact same experience. All that liquid between the water and milk and nothing but a soupy great smelling soup in the crock pot. Soooo disappointed.

      • Hi Robyn, I’m sorry to hear the recipe didn’t come out for you. I know it’s disappointing to try something new and not love it!

  41. I made this today. It was so delicious, I couldn’t help but to eat a bowl before bed! I would recommend doubling the spices. I do love cinnamon though, so maybe its just me! I sprinkled my bowl with extra cinnamon, some honey, and coconut flakes! SO GOOD!

    • Honey and coconut flakes sound delicious! I’m so glad to hear you enjoyed the recipe, Nora. Thanks so much for reporting back!

  42. Fabulous consistency! My crockpot runs a bit hot, but a little extra liquid solves that. Using your basic outline, I’ve switched it up to apple/cinnamon oatmeal as well. It’s fun to have a solid base to play around with. Thanks for sharing!

    • I’m happy to hear you enjoy the recipe, Kerrie! Apple/cinnamon sounds delicious. Thank YOU for leaving this great feedback!

    • Could you please tell how to adjust the recipe to apples and cinnamon? I don’t eat bananas due to the belly fat issue, but I want to try an over night oatmeal recipe.

      • Nancy, I’m afraid I don’t know as I’ve never tried the recipe this way! You could experiment with using applesauce instead of the mashed banana, though it won’t be as sweet so you may want add in maple syrup. I’d also cut back on the liquid since applesauce is more liquidy than bananas. If you do decide to play around, I’d love to hear what you think! I do have this cold apple cinnamon overnight oatmeal recipe you might like: https://www.wellplated.com/apple-cinnamon-overnight-oats/.

  43. Came back to say I once again made this oatmeal, but this time put Pure Whey protein powder in. Did not really change the consistency or taste! So anyone looking to up their protein content without boring shakes, this is a tasty way! I just add a splash of half and half when hearing it up, because the protein absorbs some of the liquid. 

  44. Let me just start by saying I HATE oatmeal! And I just made my second batch this morning, which means you know its good!! I’ve never enjoyed oatmeal but this recipe is delicious, filling, and great for when you just need to pop something in the microwave on a busy morning. I discovered Erin’s blog in January and have made many recipes and have yet to be disappointed! :) Thanks Erin!

    • Hi Olivia! I’m so happy you’re here, and I’m glad that you enjoy this oatmeal recipe! Thank you for taking the time to share and for the kind words about my recipes!

  45. Has anyone had a problem with the oats sticking or burning? I haven’t tried this recipe yet but another overnight recipe I tried burned and stuck no matter how often you stirred.

    • Hi Susianne, a few other commenters mentioned that they added 1 or 2 tablespoons of coconut oil to the recipe to prevent sticking. I didn’t have any problems with sticking in my batch, but everyone’s slow cooker is different!

  46. Made this….delicious!  Used coconut milk instead of regular (ran out!!) and added an extra banana since I LOVE bananas! Woke up in the morning to a wonderful breakfast.  

    • Alice, I’m so glad you enjoyed the oatmeal! Thanks for taking the time to report back and share your tweaks—I think coconut milk sounds delicious!

  47. Anyone know the 21day fix container count? This was really good and makes a lot!!

    • Hi Melissa, I’m afraid I’m not familiar with the 21 day fix, but perhaps someone else here knows! I’m so glad to hear you enjoyed the recipe!

  48. I added a little more than 1/4 cup of brown sugar, so it was sweet (I’d forgotten about the sweetness in the two bananas). I also put in 1 1/2 TBPs flax seed instead of the 3 TBPs, and it was good. I made this because I had seven bandannas on my counter that were going brown, so this was a good way to use two. :) I myself enjoyed the oatmeal – but I’m not a big fan of oatmeal in general, so I’ll have to see what the rest of my family thinks.
    Thanks for the recipe!

    • Naomi, thanks so much for giving this recipe a try and taking the time to share your tweaks and feedback! I hope it’s a hit with your family too.

  49. I can’t even begin to tell you how much I LOVE this oatmeal! I make a batch every Sunday and then eat it for breakfast all week long. I follow the recipe to a T except I leave out the flaxseed meal. And I only cook it for 4 hours on low in my crockpot…comes out perfect every time! I eat a serving with 2 tbsp of peanut butter and sliced banana and it is just so delicious and filling and hearty. Keeps me full until lunch time! My husband likes to add real maple syrup, coconut flakes, nuts or dried fruit to his. Thanks for sharing such a great recipe!

    • HOORAY Suzanne, I’m so glad to hear this recipe is a winner for your family! Thank you so much for taking the time to leave this nice review. :)

  50. Am I reading this recipe correctly? You only use one and a half cups of oatmeal?

  51. Barbara Weinstein Reply

    I made this as a surprise breakfast for overnight guests. They went crazy over the odor in the kitchen and raved over the taste.  All of us have been making it ever since. What a fabulous breakfast!!
    We use very ripe bananas for the sweetness. Perfect that way. 
    It stuck badly to the slow cooker so now I use a liner. 

    • Barbara, I’m so glad to hear this recipe was a hit for you! Thanks so much for taking the time to leave this great review.

  52. I made this recipe over the weekend and something just wasn’t right when I ate it. It smelled AMAZING when cooking, but when I ate it the next morning the after taste was really weird… The only difference I did was adding an extra banana because I had 3 and didn’t want to throw the one away, I also cooked it on high for 4 hours. Would the extra banana have anything to do with it…? Or would it have been the 2% milk I used? I love almond milk and have heard almond milk holds up a little better in the crock pot than regular milk..

    What do you think I did wrong to make the after taste not quite right…?? I really want to get this recipe right, it sounds terrific!

    Thank you!!!

  53. No we had bought the milk the same day, ok I will try it with less bananas and see if that helps. Could it have been that I cooked it on high instead of low…? 

    Thanks and I will have to try that pumpkin one!

    • Hi Karlyn! I’ve made these on high before and the flavor was fine. I’d try fewer bananas next time. I hope that helps!

    • And one more thought! Be sure that your cinnamon and nutmeg are fresh and that you don’t overuse them. Too much nutmeg especially can throw the flavor off, because it’s a strong spice. I definitely would grate your own if you can, as it tastes much, much better. You can also try only adding 1/4 teaspoon to begin with, tasting it once the oats are done, then adding more if you like to taste.

  54. Ok thank you!

  55. Just made this for my husband ,toddler and myself. Woke up to the best smelling breakfast this morning. We all enjoyed it even my picky 2 year old ate it! Thanks for sharing it so glad I came across it while searching for recipes!!

    • HOORAY Meredith! Thanks for taking the time to leave this nice review—I’m so glad everyone in the family enjoyed it!

  56. Sounds great! Sorry for this silly question but I have a crock pot … is that the same thing as a slow cooker?  

  57. Quick question. I want to make this tonight to take to work in the morning for a breakfast potluck so I was wondering if you have ever doubled or tripled it? Would the bake time be the same?

    • Hi Ellen, I think you would be safe to double it. I’ve never tried, but that would fit in the slow cooker just fine. Tripling would be a really big batch, and sometimes multiplying a recipe by that much can have odd results, so I’d start with doubling and see how it goes. The cooking time would be about the same, I think.

      • Thank you for your quick reply. I just finnished putting it all together and I just doupled it. That should be enough to feed everyone. I will let you know how it turns out. I also made a small side of fruit (rasberries,blueberries, strawberries and blackberries) that my co-workers can add as well as bananas. Thank you for your recipe and I hope it turns out.

  58. I followed the recipe to a T but mine turned into a soupy mess of gluey, watery goop with burnt, boiling edges. My little kids wake me up a lot at night and I smelled the heavenly scent and was starving! But I can’t eat it! I’m so disappointed I could cry. My crockpot was a gift and it’s only got low and high and nothing else. It certainly doesn’t work for this recipe. I would experiment but I don’t want to waste my organic steel cut oats and I don’t think I could handle another night of that gorgeous smell only to have it not work. I might throw the whole crockpot through the window! ?? I rated it lower because it’s not a recipe that works for everyone, looks like a lot of people had to make adjustments of some sort, and it didn’t work at all for me. The idea was brilliant though! 

    • Hi Laura, I’m sorry the recipe didn’t come out for you. As you already noticed in the comments, many people have had success, but every slow cooker seems to be different! I know it’s disappointing to try a recipe and not have it come out, so I truly wish you would have enjoyed this.

  59. Hi- followed the banana recipe to the letter – but doubled it.  Came out perfect, great texture, smelled yummy!  The only strange thing was the color of the bananas- they looked like bits of ham- pinkish Brown- their texture was as expected and they tasted good- but didn’t look very appetizing- any thoughts?  Thanks!

    • Hi Rick, I’m not sure what may have caused that, as it’s never happened to me before! Perhaps the bananas were extra ripe? I’m glad to hear that it was delicious regardless!

  60. I love this so much! It’s absolutely perfect for breakfast. I get up super early for work and right now just make some microwaved egg whites and a handful of berries. Which is fine but gets old after a while. This sounds absolutely amazing and healthy. Perfect to take to work with me. AND, I have a few containers of steel cut oats that I haven’t used yet. So this is perfect for pantry cleanout too!

  61. This is by far the coziest breakfast!!

  62. Hi, Erin! I made this over the weekend it was fantastic! I’m excited that I have another slow cooker oatmeal option. I added peanut butter, toasted pecans, and a swirl of maple syrup to it. Very filling! Thanks for creating this recipe.

    • Hooray Stefanie, I’m glad to hear this was a hit! Your additions sound amazing. Thanks for taking the time to report back!

  63. …just wanted to say thanks for sharing your recipe! It made for a hot and delicious “Brinner”, after a long Wednesday evening of Church and Choir Practice. Our whole family enjoyed it, including the kids. Thanks Again! ?

  64. Hi Erin! I recently stumbled across your blog and I am in love!!!! I can’t wait to try some of your recipes. I was wondering if you could tell me if it is absolutely necessary to put the ground flaxseed meal in this recipe? I have all the other ingredients except for this one. Thank you!

    • Hi Sarah, you can definitely omit it if you don’t have it. And see the notes section below the recipe for some additional substitutions you could make.) Enjoy!

  65. Happy accident! I was using a new crockpot and managed to set it to warm instead of low. Was a little concerned when I woke up and didn’t smell the sweet banana bread aroma I was expecting. They actually came out wonderful!!! No sticking at all, liquid all absorbed, and honestly a perfect texture. It was only cooking for about 6 hours. Am thinking I will just continue to do them this way from now on. Thank you so much for all your wonderful recipes!!!They have all been hits!!!

    • Hi Trista, I’m so glad the oatmeal still came out! Thanks so much for giving the recipe a try and taking the time to report back.

  66. I’ve been looking for a really good and this hit the spot. It does have a really good banana nut flavor but you can top it with so many things.

  67. Irma Krollpfeiffer Reply

    Hi Erin, can this recipe be made in a two quart slow cooker?  Thanks in advance. Irma 

    • Hi Irma! I think you could do that if you cut the recipe down to 1/3 or 1/4 of the original amount. It would be experimenting though, as I’ve never tested it this way myself. If you decide to play around, I’d love to hear how it goes!

  68. I’ve never made meal in the crockpot but I certainly love others who’ve tried this. I ended up doing it on high for four hours and it was perfect! Being new to the oatmeal craze steel cut is the way to go. Many thanks for this wonderful recipe. I can’t wait to try it next with some coconut oil, that sounds superb. 

  69. My entire family loved this recipe! The best overnight steel cut oats recipe we’ve ever tried, hands down!

  70. I’m sad b/c this was the 2nd time I’ve made this, and it came out not tasting good. I followed the recipe to the tee. The nutmeg seems to be the culprit even though I bought the whole kind that I needed to zest myself. Not sure what happened. Any ideas? It also burned on the bottom even though I got up in time to turn the crockpot to Warm from Low.

    • Hi Jill, I’m sorry you didn’t enjoy the oatmeal! If the nutmeg isn’t a flavor you enjoy, you can certainly leave it out. Everyone’s slow cooker seems to cook differently—yours may run a little hot if the bottom burned. I know it’s disappointing to try a new recipe and not have it come out, so I truly wish you would have loved this!

  71. THIS.  IS.  MAGIC. HA!  I believe I have made this 5X in the last month as we’ve had company for the holidays & everyone is OBSESSED w/ it.  It is DELICIOUS!!!  We did add a little brown sugar to each serving & topped w/ all sorts of dried fruits, fresh fruits, pumpkin seeds, cinnamon chips, peanut butter chips, nuts etc etc…we are HOOKED.  Thank you so much for this AMAZING recipe.  Freezes wonderfully as well for a quick healthy breakfast!  MAKE THIS!!!!!

  72. Hi!  I’m hoping to make a large portion for my preschool class next week when we read The 3 Bears (it will be our porridge;). Do you think it would work if I just triple everything?  Do you suggest any alterations to the recipe?

    Thank you so much!  Excited to try it!

    • Hi Lisa! What a fun idea! I’ve never tried this recipe tripled—my guess is that you would be safe with doubled, but I’m not sure about tripled. Big batches of things can sometimes not cook the same way. If you need a really, really big batch, perhaps you could borrow a slow cooker from a friend and have two batches going at the same. I hope you enjoy!

  73. Hi Erin, I came across this recipe last year and loved it. I have made it many times. I have tried several other oatmeal recipes, as I love oatmeal, but I believe this is my favorite, and I thought you should know!! My husband who is not fond of oatmeal, if you can believe that, thinks it’s pretty good! Thank you so much!

  74. Hi Erin! I’m so excited to try this recipe, one quick question, I’m looking for a nonstick spray alternative that’s not a liner, do you think adding butter to the recipe or coating the slow cooker in butter or coconut oil etc will do the trick?

    • Hi Naomi! I haven’t tried it myself, but other readers have added coconut oil to the recipe and not had trouble with sticking. I hope that works for you too if you decide to give it a try!

  75. I made this the other day. Delicious. I added some brown sugar. I used a liner for my crockpot

  76. I made this and came out like liquid. I think the steel oats and liquid ratio was wrong. Oh well. 

    • Carolo, did you use regular steel cut oats—not quick-cooking steel cut, old fashioned, or any other kind? I’m sorry it didn’t come out! I haven’t had issues with it being liquidy before. No matter what though, I know it’s disappointing not to have a recipe come out as expected, so I wish it would have been perfect for you!

  77. This is THE best oatmeal I’ve ever had. I followed directions exactly, other than using coconut milk instead of skim and ground nutmeg. Perfect texture and flavor combination. I topped mine with dark chocolate chips, walnuts, and peanut butter. Amazing that it’s only sweetened by the bananas! Perfect way to start the day. Thanks for a keeper recipe!

  78. I’m not sure what I did wrong, went strictly by the recipe and this has no taste, no flavor at all.

    • Hi Paula, I’m sorry to hear you didn’t enjoy the recipe! Are your spices fresh? Sometimes that can be a culprit. Many other readers have loved the recipe, but I know everyone has different tastes, so I truly wish you would have loved it.

  79. I made this recipe on the “KEEP WARM” setting for 5.5 hours, and it was perfect. I hope you will consider adding that suggestion to the instructions. So many people reported that their oatmeal turned into soupy mush, and it’s such an easy fix! Also, maybe you could list what brand/type of crockpot you used? That way we have an idea if our cooking time will be similar to yours.

    I added 2TBSP maple syrup, and 1 T coconut oil. I used a mix of almond milk/ flax milk/ 1% milk. I added half an apple, and 2/3cup walnuts to the cooker (so we don’t add any topping later, since my kids serve themselves when they wake up.) I used dried nutmeg 1/4t, and added 1/2t of pumpkin pie spice. It was delicious!

    I currently have a Proctor Silex, however my last slow cooker required using the “keep warm” for oatmeal also. I saw that only two other posters mentioned this- I hope this tip will help someone else.

    Prior to cleaning a messy slow cooker, I always fill it with water, then set it on high for an hour. It becomes much easier to clean after you boil water in it, and it avoids having to use liners.

    Lastly, my crockpot does not have a timer, so I use my own plug-in timer that goes into the wall, and I set for 5.5 hours. It’s like the timer for outdoor Christmas lights, but it’s small and only $10 at any store. (We use this timer on our living room lights when we’re out of town, to deter burglars.)

    Thanks for the recipe. Sorry for the long comment! :)

    • Hi Donna! I’m glad you enjoyed the recipe, and thanks for sharing your tips too! I do link to the model of slow cooker I use if that info is helpful (it’s under the “Recommended Tools” heading in the blog post).

    I would like to make this as a banana bread loaf. I would like to put it in a loaf pan in water in my crock pot. My loaf pan is 9 x 5 inches. How long do should I cook it ?

    I made this about 3 years ago and it was amazing. I just can’t remember how long I cooked it for. Thanks for your help.

    • Dorothy, you mean you baked the oatmeal in a loaf pan? I honestly have never tried this, so I’m afraid I can’t advise you here. If you do try it though, I’d love to hear how it goes!

  81. This was fabulous!! I made mine during the day and did not take 4 hours of high..it was done at 2 1/2 to 3 hours and smelled amazing…just like banana bread!!! I added chopped banana and granola mix with raisins and almonds when it was done. The only substitute I made was that I did not have flaxseed on hand so I used a super grain blend of buckwheat, tri-color quinoa, and millet. Thank you for sharing this recipe!!!

  82. Elissa Leader Barpal Reply

    This was the most delicious oatmeal! I didnt have the ripe bananas but added fruit after. I ate this all week at work!

  83. This was so delicious! For anyone wanting to use old fashioned oats. It took 5 hours and came out perfect!

  84. Does cooking it in a water bath require longer cooking time?

    • Hi Andrea, I would recommend still checking the recipe for doneness within the time frame given, but it should be able to go longer in the crock pot without burning.

  85. hi! what is 1.5 cups of oats? is it 1 and a half cup? thank you

  86. I made this two days ago and I have to say it came out great. I wanted to keep and eye on it so I made it during the day. My old crock pot must run hot because on low it was done in 4 1/2 hours. I followed the recipe exactly with the exception of flax seed, which I did not have on hand. I have to say it made a lot. There are three in my family and after 2 days of breakfast I still have some in the fridge. It warms up quite easily. My weakness is with fresh blueberries and maple syrup. I used McCanns steel cut oats which cost a little more but are worth it.
