5 Ingredient Mexican Casserole–an easy 5-ingredient dinner made with tender chicken, tortillas, refried beans and enchilada sauce for a family-friendly meal. Make it in the oven or the slow cooker.

5 Ingredient Mexican Casserole
This is one of those recipes that makes life just a bit easier. I love how it comes together with only 5 main ingredients (not counting oil, salt, and pepper) but still tastes great! The chicken gets coated in enchilada sauce and creamy refried beans, and then everything bakes up with melty cheese and soft tortillas layered throughout. If you want to make it faster, try using rotisserie chicken.
Ingredients/Substitution Ideas
- Olive oil–or avocado oil
- Boneless skinless chicken breasts–or boneless skinless chicken thighs
- Kosher salt
- Black pepper
- Enchilada sauce–green or red
- Refried beans
- Tortillas–or corn tortillas
- Sharp cheddar cheese–or Monterey Jack or Mexican blend cheese
Steps
Heat oven to 350° F. Spray a 9×13 inch baking dish with non-stick cooking spray.
Heat a large pan over medium high heat. Add in the oil and swirl around. Add in the chicken, sprinkle it with salt and pepper and cook until no longer pink in the middle.

Stir in the enchilada sauce and refried beans, until smooth. Turn off the heat.

Layer half of the chicken mixture, half of the tortillas and half of the cheddar twice in the 9×13 inch baking dish.

Bake for 30 minutes. Let sit for 5 minutes. Serve and enjoy!

Notes/Tips
- Serve with a side salad, chips and salsa, or some Spanish rice.
- This recipe can be gluten free if you use corn tortillas instead of flour tortillas.
- Want to save time? Use rotisserie chicken and skip the sauté step.
- I used 5 large flour tortillas. If you use corn tortillas I would use 8-10.
- For extra flavor, stir in a can of diced green chiles or a sprinkle of taco seasoning.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days. Freezing it is okay but the tortillas kind of turn mushy.
- Other recipes you can make with refried beans are Greg’s Taco Lasagna and Slow Cooker Chicken Enchilada Soup.
