I attribute my regular cravings for Mexican flavor to my mother, who I’m convinced needs a dose of Mexican food at least twice a week in order to maintain her equilibrium.

  • Growing up, at least 50% of the meals we ate out were Mexican…or “Mexican” depending upon how strictly you define the term.
  • Our traditional Christmas night dinner? My grammy’s Green Chile Chicken Enchiladas.
  • Clearly, the love of Mexican food spans generations.

Now, I will not for a second pretend that the Mexican recipes I make at home, such as this crockpot Mexican casserole, are authentic, but that doesn’t mean they aren’t delicious.

Make this recipe tonight, then stow some away for the next time you need a fast, healthy dinner…or for when your own Mexican craving strikes!

ingredients in a crock pot to make a meatless Mexican casserole

This particular crockpot Mexican casserole recipe is ultra easy to make, reasonably healthy, and offers the convenience you are seeking when you pull out your crock pot.

No, you won’t find this crockpot Mexican turkey casserole recipe on an actual Mexican restaurant menu, but when your family is clamoring for second helpings, you’ll be too busy congratulating yourself on serving an easy meal that’s loaded with fiber and protein to worry about that small detail.

How to Make Crockpot Mexican Casserole

Like the more authentic Mexican food that inspired it, this ground turkey slow cooker casserole is the right mix of comfort and freshness.

The spices are rich but not overpowering, and like my other slow cooker Mexican recipes, from Slow Cooker Taco Casserole to Crockpot Mexican Chicken to Slow Cooker Chicken Enchilada Soup, it’s a complete crowd pleaser every time I serve it.


The Ingredients

  • Ground Turkey. Not only does ground turkey help make the casserole more satisfying, but it also adds scrumptious flavor. Plus, it’s a lean and healthy source of protein.

Substitution Tip

If you prefer, you can use ground chicken to make slow cooker Mexican chicken casserole. If you enjoy crockpot casseroles with ground beef, you can use it instead.

  • Quinoa. Helps make the casserole extra satisfying. Additionally, quinoa is packed with fiber and is considered and complete protein.
  • Red Enchilada Sauce. Smoky and bursting with beloved Mexican flavor. Either canned enchilada sauce or my stellar homemade red Enchilada Sauce will work well.
  • Black Beans. Creamy and nutritious. Black beans are rich in fiber and protein.
  • Fire-Roasted Tomatoes. Incredibly rich, smoky flavor packed into the convenience of a can.
  • Corn. A delicious and sweet addition to our Mexican casserole.
  • Bell Peppers. Red and green bell peppers add beautiful color and nutritional benefits to the dish.
  • Spices. Garlic powder, chili powder, and cumin give the casserole bold, earthy flavor. Keep these on hand at all times.
  • Mexican Blend Cheese. For that must-have melty, cheesy topping.

The Directions

  1. Brown the turkey, then transfer it to a slow cooker.
  2. Stir in the remaining casserole ingredients (except the cheese). Cook on HIGH for 2 1/2 to 3 hours or on LOW for 5 to 6 hours.
  3. Stir in part of the cheese, and add the remaining cheese on top. Cook on HIGH until the cheese melts. ENJOY!

Dietary Note

For vegetarian crockpot Mexican casserole, replace the meat with extra black beans.

    1. Hi Jen! I’ve only tested the recipe as written so I wouldn’t be able to advise on that substitution. If you decide to experiment, let me know how it goes!

  1. We Love this recipe! Even my picky kids devour it. It’s the perfect meal and the leftovers store/freeze well. We make it at least once a month. My boys enjoy eating it with tortilla scoops. I didn’t think I’d like it because of the quinoa as I had never really liked it before but in this recipe its great. Thank you!5 stars

  2. I’ve made this recipe several times and my family lovesssss it! I use rice instead of quinoa and ground beef instead of turkey. It comes out amazing every single time. I love putting a little extra rice and cheese in it and i always top it with sour cream! Its so yummy. Thank you for this recipe!5 stars

    1. Hi! When you swapped out rice for quinoa did you also change the water ratio? I’d like to try this with rice as well! Thanks!

  3. Hi! Will the turkey overcook if I cook it the night before and then throw it in the crockpot the next day for the time recommended (2-3 hours on high).

  4. I love this recipe! Super easy to make, my boyfriend recommends this all the time when I make his lunch for work!5 stars

  5. I am truly obsessed with this recipe. I’ve made it so many times over the last few years and am only just reviewing now because it has become such a staple for me. It’s so filling but the ingredients are so wholesome and healthy that I never feel overstuffed or gross after eating a whole bowl (or 2). I add a chopped jalapeño to the crockpot and usually stir in 1.5x the recommended cheese, but I don’t add cheese to the top of the crockpot and instead top individual bowls while serving. I also always serve with lime juice, avocado, green onions, cilantro, and hint of lime tostitos on the side. My friends and boyfriend love it too! An easy crowd pleaser and a great meal for work lunches!5 stars

  6. This was fabulous! I was looking for easy slow cooker recipes since temps have been over 100for two weeks now in Houston and heating the house up with the stove or oven was not enticing.
    This recipe is so good! It tastes like chili but better! I omitted cheese because I didn’t think it needs it but topping it with sour cream, green onions or other chili toppings would be great! I’m trying another recipe tonight!5 stars

  7. This was WONDERFUL! I used a full can of corn, which was more than a cup, topped our bowls with sliced avocado and chowed down! Even my 2 year old finished his bowl (he loves anything with beans). 10/10 will recommend.5 stars
