If you love enchiladas but don't have time to roll and bake, this slow cooker chicken enchilada casserole is the shortcut you need. It's everything you want: cheesy, saucy, full of flavor; and it all comes together with minimal effort right in your crock pot.

This crock pot chicken enchilada casserole is proof that comfort food doesn't have to be complicated. Just layer, cook, and serve-no oven, no fuss, and no leftovers (if you're lucky). Serve with a side of roasted chili corn salsa, Salsa verde or my personal favorite: Mexican corn dip.

- Chicken breasts: Choose fresh, high-quality boneless skinless chicken breasts with no visible blemishes or off-odors.
- Red Enchilada Sauce: The flavor foundation; choose based on your desired heat level.
- Garlic powder: potency matters, so check freshness.
- Cumin: freshness is key for optimal flavor.
- Corn tortillas: Essential for texture and authenticity; flour won't work here.
- Cheddar cheese: Grate your own sharp cheddar for better melting and flavor.
- Black olives: Select olives packed in water for a cleaner taste, or try Kalamata for more complexity.
- Sour cream: Use full-fat sour cream or Mexican crema for the best flavor and texture.
- Fresh cilantro: Pick bright green bunches without yellowing, and store properly to maintain freshness. To keep it fresh longer, store with stems in water and cover with a plastic bag in the refrigerator.
Can I use rotisserie chicken instead of chicken breasts?
Using a rotisserie chicken is an excellent substitution for this recipe. It can save time and add extra flavor. Here's how you can adjust the recipe to incorporate a rotisserie chicken:
- Remove the meat from the rotisserie chicken, discarding the skin and bones. Shred the meat into bite-sized pieces. You'll need about 3-4 cups of shredded chicken.
- Skip the step of cooking raw chicken in the slow cooker. Instead, you'll layer the pre-cooked shredded chicken with the other ingredients.
- To prevent the casserole from becoming dry (since you're not adding raw chicken that would release juices), consider these adjustments:
- Increase the amount of enchilada sauce by about ½ cup.
- If the mixture seems dry when assembling, add ¼ to ½ cup of chicken broth for extra moisture.
- Layer the ingredients in your slow cooker as follows:
- Start with a thin layer of enchilada sauce
- Add a layer of torn corn tortillas
- Spread a layer of the shredded rotisserie chicken
- Sprinkle with some of the spices (garlic powder and cumin)
- Add some cheese and olives
- Repeat these layers until all ingredients are used, ending with a layer of cheese on top
- Cook on low for 2-3 hours, or until heated through and the cheese is melted. The cooking time will be shorter than with raw chicken since everything is pre-cooked.
- Let it stand for about 10 minutes before serving to allow it to set.
