I am either on the cusp of a great discovery or the last to know, because Instant Pot Sweet Potatoes are officially the best, most convenient way to steam a sweet potato I’ve encountered.

You cool Instant Pot kids—have you been cooking your sweet potatoes this way all along?

Is there a secret underground club where people wink at each other knowingly, all while enjoying their perfectly tender, lightly fluffy, yet also creamy, sweet potatoes?

As of this day, you and I are IN the sweet potato club, my friends. Maybe we can have a secret handshake or better yet, a secret stash of butter.

Like this Air Fryer Sweet Potato recipe, making sweet potatoes in the Instant Pot is cool and convenient.

  • The sweet potatoes cook in a fraction of the time they’d take to bake.
  • You don’t need to fuss with peeling them.
  • The Instant Pot frees up your oven, meaning you can either use your oven for something else OR keep it turned off to avoid heating up your kitchen.
  • The sweet potatoes steam perfectly. We’re talking creamy and fluffy, not overbaked or gummy. (They’re perfect to use in these Whole30 Breakfast Bowls!)

The below Instant Pot sweet potatoes recipe is for cooking whole sweet potatoes. If you’re looking for Instant Pot cubed sweet potatoes, check out this post for Instant Pot Mashed Sweet Potatoes, which uses them. (This Roasted Sweet Potatoes recipe also uses chopped sweet potatoes.)

I’ve included cooking times, key information, and suggestions for storage and reheating so that you can steam a whole batch, then reheat them for quick and easy sides throughout the week.

How to Cook Instant Pot Sweet Potatoes

Use this guide to find cooking times, tools, and a few other key tips to make perfect sweet potatoes in your Instant Pot or similar electric pressure cooker.

This method is easy, hands-free, and has become my new preferred way for steaming sweet potatoes.

Equipment You Will Need

  • Instant Pot or Similar Electric Pressure Cooker or Multicooker. This is the Instant Pot I own and love—it’s a basic 6-quart model. You can use this method for any size Instant Pot (3, 6, or 8 quart). Simply ensure you adjust the number of sweet potatoes and amount of water accordingly. (See “Scaling This Recipe Up or Down” below for more.)
  • Trivet. To keep the sweet potatoes from burning on the bottom, you will need to insert the handled trivet that came with it, which also functions as a steamer basket. If you cannot find your trivet, I’d suggest finding an inexpensive replacement, such as this one.


You only need two ingredients to make perfect Instant Pot sweet potatoes.

  • Water. Make sure to use COOL WATER so that your sweet potatoes don’t start cooking early after the Instant Pot is sealed. You’ll need 1 cup for the 3-quart and 6-quart Instant Pot models or 1 ½ cups for the 8 quart.
  • Sweet Potatoes. Pick sweet potatoes that are about the same weight so that they cook evenly. In addition to being delicious, sweet potatoes are also incredibly healthy. They’re packed with Vitamin-A, calcium, and iron (read more health benefits here).

Of course, don’t forget your TOPPINGS. Butter, salt, and black pepper are the classic, but certainly not only, options. See below for more ideas. 

Cooking Times

How long it takes to cook sweet potatoes in the Instant Pot varies by sweet potato size, the amount of time your Instant Pot needs to come to pressure, plus 10 additional minutes for the pressure to release.

Sweet Potato Cooking Times by Size

Set your Instant Pot to the below number of minutes, based upon the size of your potatoes. Remember to choose sweet potatoes that are roughly the same size so that they all finish cooking in the same amount of time.

  • Small Sweet Potatoes (6 to 8 ounces). 12 minutes.
  • Medium Sweet Potatoes (8 to 12 ounces). 17 minutes
  • Large Sweet Potatoes (12 ounces or more). 25 minutes.

Calculating the Total Time to Steam Sweet Potatoes in the Instant Pot

Please note that each of the above times is the number of minutes the sweet potatoes cook once the Instant Pot has come to pressure.

  • The timer on your Instant Pot will not start counting down until the pressure builds.
  • Then, once the timer is up, the pressure still needs to release for 10 additional minutes.

That means that the total amount of time it takes to steam the sweet potatoes in the Instant Pot equals:

  • Time to come to pressure (for four medium sweet potatoes in my 6-quart Instant Pot, I need roughly 10 minutes), PLUS
  • Pressure cook time (based on the size of potato; for this example, let’s say 17 minutes for medium), PLUS
  • Pressure release time (10 minutes)

That means my total cook time for medium sweet potatoes in a 6-quart Instant Pot is 37 minutes (10 minutes coming to pressure + 17 minutes pressure cook time + 10 minutes pressure release time).

While 37 minutes might sound like a lot, those same sweet potatoes would need 50 minutes or longer in the oven; plus the oven would be running the entire time.

The Instant Pot is more efficient, keeps your oven free, and steams the sweet potatoes perfectly.

For a fast, hands-free side, start the sweet potatoes cooking at the beginning of your dinner prep, and they’ll be ready before you know it.

Recipe Step-by-Steps

Here’s how we put the above ingredients and cook times together.

You can also check out the Instant Pot sweet potato video I have added to this post to see the recipe in action.

How to make sweet potatoes in the Instant Pot
  1. Clean the sweet potatoes, and use a fork to pierce the outsides.

  2. Place the potatoes on the Instant Pot trivet. Add the water.
  3. Cook on HIGH (manual pressure) according to the size of your potatoes (see above for details).
  4. Perform a natural release for 10 minutes.

  5. Remove, then when cool enough to handle, slice the potatoes open. Add desired toppings, and ENJOY!

While you do not have to poke holes in the sweet potatoes to cook them in the Instant Pot, personally I prefer to do so (mostly out of habit). If you forget, it’s not an issue. Your sweet potatoes will still cook evenly.

Scaling the Recipe Up or Down

You can follow this recipe for any size of Instant Pot.

The number of sweet potatoes you can cook in your Instant Pot at once will vary based on the size of your sweet potatoes and the size of the Instant Pot model you own.

  • I estimate 3 sweet potatoes will fit in the 3-quart and up to 8 could fit in the 8-quart, though I’ve only tested this recipe in my 6-quart (I cook 4 potatoes at once).
  • I advise placing no more than 2 layers of sweet potatoes into the pot to ensure they cook evenly.
  • The pressure cook time you set (12 minutes for small sweet potatoes, 17 for medium, 25 for large) will stay the same regardless of how many sweet potatoes you cook.
  • I haven’t tested this recipe with only one sweet potato, but I see no reason why that wouldn’t work (again no need to change the cook time).

This recipe can also be cut in half for any size Instant Pot. No adjustments to the recipe are needed.

Storing and Reheating Steamed Sweet Potatoes (Meal Prep)

Cooking a big batch of sweet potatoes at once is a great way to get ahead on meal prep for the week.

  • To Store. Leftover sweet potatoes can be stored in an airtight storage container in the refrigerator for up to 4 days.
  • To Reheat. Rewarm potatoes in the oven at 350 degrees F until hot. You can also reheat them gently in the microwave.
  • To Freeze. Individually wrap leftover potatoes, and freeze them for up to 3 months. Let thaw overnight in the refrigerator before reheating.

What to Serve with Steamed Sweet Potatoes

  • Chicken. Instant Pot sweet potatoes and chicken would be a delicious meal.
  • Fish. This simple Blackened Salmon would be tasty paired with sweet potatoes.
  • Veggies. Serve these Grilled Portobello Mushrooms with sweet potatoes for a vegetarian meal.

Topping Suggestions

In addition to being an easy and healthy side dish, you can turn sweet potatoes into a main event!

How to cook perfect Instant Pot Sweet Potatoes! Key cook times for perfectly fluffy, tender steamed sweet potatoes, plus the best ways to serve them.

Prep: 3 minutes
Cook: 17 minutes
Total: 40 minutes

Servings: 4 sweet potatoes


  • 4 sweet potatoes that are all roughly the same size
  • 1 cup cool water increase to 1 1/2 cups if using the 8-quart Instant Pot
  • For serving: a sprinkle of salt and pepper butter, and any other toppings of choice


  • Scrub the sweet potatoes (no need to peel) and pierce a few times with a fork.
  • Place the stainless steel trivet that came with your Instant Pot into the Instant Pot with the handles up. Arrange the sweet potatoes on top, and pour in the water.
  • Close and seal the Instant Pot. Cook on HIGH (manual) pressure for 12 minutes (for small, 6 to 8 ounce sweet potatoes), 17 minutes for medium sweet potatoes (8 to 12 ounces), or 25 minutes (for large sweet potatoes that are 12 ounces or more).
  • Once the cooking time is up, let the pressure release naturally for 10 minutes. After 10 minutes, carefully vent to release any remaining pressure, then open the lid.
  • Carefully remove the sweet potatoes with tongs. Make a slit across the top to open (fluff up the insides with a fork) or cut in half. Serve immediately with toppings of choice.



  • TO STORE: Leftover sweet potatoes can be stored in an airtight storage container in the refrigerator for up to 4 days.
  • TO REHEAT: Rewarm potatoes in the oven at 350 degrees F until hot. You can also reheat them in the microwave.

  1. This was the very first thing I had made in my Instant Pot.  It was the best way I have ever had potatoes (either sweet or white).  It is a very fast way to get perfect potatoes.  I am surprised that Erin took so long to find out about this but better late than never!5 stars

  2. This recipe didn’t work for me. I have a 6 cup Instant Pot Duo and I tried this with 2 sweet potatoes, each about 1lb. I used 1 cup of water and set the time for 25 minutes on high pressure as stated in the recipe (“ Large Sweet Potatoes (12 ounces or more). 25 minutes”). It took only a few minutes to get up to pressure, then it cooked for 25 minutes, then it took 30 minutes to depressurize but the sweet potatoes were still hard in the middle.

    Had I cooked them in the oven for this long they would have been done and tasty.

    1. I’m sorry you to hear had trouble with the recipe, Allen. I know it’s frustrating to try a new recipe and not have it turn out. I (and many other readers) have enjoyed them, so I really wish they would’ve been a hit for you too! It’s hard to say what went wrong without being in the kitchen with you.

  3. Not nearly enough cook time! I was so excited about doing sweet potatoes in the IP for the first time and was dreaming of perfectly soft, fluffy potatoes but unfortunately ended up with hard, carrot-like potatoes after 13 minutes in the IP (I even weighed my potatoes – 8 oz!) then an additional 3 because they were hard after the first cook + rest.

    1. Hi Heather! I’m sorry to hear the timing didn’t work for you. The timing has worked well for me (and others) so I wish it would of been a hit for you too. Was there any air escaping during process of it coming to pressure? This will result in a recipe not turning out as intended.

  4. This is absolutely the best way to make sweet potatoes, thank you for the weight/time ratios! I usually buy 8 to 9 oz sweet potatoes and split the time between the small and medium that you list by going with about 15 minutes cooking and then the 10 minute NPR. They are perfect every time.

    Another important thing people should know about sweet potatoes is that if you cook them this way, and then cool them overnight in the fridge, you can reheat and eat them, and they’re much healthier for you. The cooling process increases the resistant starch in the sweet potato, which not only lowers its glycemic index, it has a host of other important health benefits backed up by scientific research. I love to pre-cook my sweet potatoes, let them cool, and then individually bag and freeze them for later use. Using the IP method of cooking them makes this whole process a breeze!5 stars

  5. I have used this recipe twice and gotten great results! Much faster than baking. I used 4 medium sized potatoes at 17 mins in a 6 qt with 1c water. Thanks Erin!5 stars

  6. My favorite kind of recipe: simple, delicious, and repeatable! Extremely helpful that you included different cooking times for different weights of sweet potatoes were also included. Many thanks!5 stars
