This Slow Cooker Chicken Enchilada Casserole is one of those easy, comforting meals that you'll find yourself coming back to again and again. Just layer everything in the slow cooker and let it do the work! Whether it's a busy weeknight or a lazy Sunday, this is the kind of no-fuss dinner the whole family will love.

This Slow Cooker Chicken Enchilada Casserole is the definition of a set-it-and-forget-it meal. Just toss everything in the crock pot, walk away, and come back to a pot full of deliciousness. Right at the end, you'll shred the chicken and stir in some cheese and corn tortillas for that cozy, casserole-style texture that's packed with bold, comforting flavor. I like to serve it topped with sour cream, salsa and avocado-but whatever you've got on hand works. My kids love scooping it up with tortilla chips, but it's just as good on its own or spooned over rice for a super satisfying dinner. Enjoy!

You will also need a cutting board and knife, and a cheese grater.

Ingredients & Substitutions
- Chicken breasts: You can substitute with chicken thighs if preferred.
- Canned diced tomatoes: I also like to use the fire roasted diced tomatoes for extra flavor.
- Onion - I recommend a yellow onion, but white or red work too.
- Frozen corn - You could substitute with drained, canned corn or fresh corn kernels if preferred.
- Canned green chiles - I love the flavor these add. Choose a heat level you're comfortable with - they range from mild to spicy.
- Garlic - I prefer using fresh garlic to the jarred, minced stuff.
- Red enchilada sauce - I like Siete's Enchilada Sauce but use your favorite brand. Keep in mind that some enchilada sauces have more salt than others so be sure to taste before serving and add additional seasoning as needed.
- Taco Seasoning - I'm also a bit fan of Siete's Taco Seasoning, but again your favorite brand or homemade will work!
- Cheese - I like using Colby Jack for this recipe, but you can use Monterey Jack, Cheddar, or whatever you have on hand. I highly recommend shredded your own cheese for this recipe. Pre-shredded is fine in a pinch but you can definitely tell a different when you shred it at home.
- Corn tortillas - If you want to make this recipe gluten free just be sure to check the label.
- Sour cream - I recommend using full fat.
- Lime - This is optional but I find that a squeeze of lime juice really elevates the flavor of this dish.
Optional Toppings:
- Avocado slices
- Sliced jalapenos
- Sour cream
- Salsa
- Green Onions
- Hot Sauce

Recipe FAQs
Absolutely! Chicken thighs work great in the slow cooker and have fantastic flavor.
That is completely up to you! For a mild dish be sure to choose mild green chiles and enchilada sauce. If you prefer more heat in the dish select spicier labeled ingredients. You can also add additional chiles or hot sauce to really take the heat level up.
Yes, I love freezing this recipe in individual portions in my Souper Cubes. Be sure to store it in an air tight container and it will last about 3 months. Just defrost in the fridge overnight before reheating.
Technically yes but I don't really recommend it. Corn tortillas hold up much better in a slow cooker dish while flour tortillas tend to get soggy.
Yes, this recipe can easily be made gluten-free. Just check the labels on your corn tortillas and taco season to ensure that they are gluten free and you should be good to go.
