Ingredients You Need

Chicken and base:

2 to 2.5 pounds boneless skinless chicken breasts
- Use thighs if you like richer flavor and extra tenderness.
1 medium yellow onion, finely diced
1 green bell pepper, diced
1 red bell pepper, diced
1 can (4 ounces) diced green chiles, mild or hot
1 can (15 ounces) black beans, drained and rinsed
1 cup frozen corn (no need to thaw)

Sauce mixture:

2 cans (10 ounces each) red enchilada sauce
- I like Hatch or Las Palmas for deeper flavor.
1 cup salsa (chunky, restaurant style, or fire roasted)
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon ground cumin
1 teaspoon chili powder
½ teaspoon smoked paprika
½ to 1 teaspoon kosher salt, to taste
½ teaspoon black pepper

Tortillas and cheese:

10 to 12 small corn tortillas, cut into strips or wedges
- Use flour tortillas if you prefer a softer, less textured bite.
2 to 2½ cups shredded cheese
- Mexican blend, Colby Jack, or cheddar all work well.
- Pre-shredded cheese saves time and still melts nicely.

Optional toppings:

Sour cream or plain Greek yogurt
Diced avocado or guacamole
Chopped fresh cilantro
Sliced green onions
Shredded lettuce
Diced tomatoes
Lime wedges

Pantry shortcuts and notes:

Use rotisserie chicken in a pinch; add it during the layering step and shorten cook time.
Use canned corn if you do not have frozen; drain it well.
Use homemade enchilada sauce if you keep some in the freezer; thaw it first.

Equipment list:

5 to 7 quart slow cooker or crockpot
Cutting board and sharp knife
Can opener
Mixing bowl and spoon
Measuring spoons and cup
Tongs or two forks for shredding chicken
Ladle or large spoon for serving

Quick Tips & substitutions

Use chicken thighs if you want extra juicy meat that holds texture.
Use mild enchilada sauce and mild chiles for kids; add hot sauce at the table for spice lovers.
Swap black beans with pinto beans or skip beans if you avoid them.
Use flour tortillas if your crew prefers a softer, less rustic texture.
Cut tortillas into strips instead of wedges to make scooping easier.
Stir in extra cheese near the end if you want a super cheesy top layer.
Use Greek yogurt instead of sour cream to add protein and a tangy topping.
Use leftover shredded chicken and cook only until the cheese melts and the casserole heats through.
Spray the slow cooker insert with cooking spray to prevent sticking and make cleanup easier.
Let the casserole rest 10 to 15 minutes before serving so it thickens and slices more neatly.

How to Make Crockpot Chicken Enchilada Casserole Recipe

Step 1: Prep the slow cooker and veggies

Spray the inside of your crockpot with nonstick cooking spray or rub it with a little oil. Dice the onion and bell peppers into small, even pieces so they cook at the same rate. Drain and rinse the black beans and set them aside with the corn and green chiles.

Step 2: Mix the sauce

In a mixing bowl, combine enchilada sauce, salsa, garlic powder, onion powder, cumin, chili powder, smoked paprika, salt, and black pepper. Stir until the mixture looks smooth and even. Taste a tiny spoonful and adjust salt or chili powder if you want more kick.

Step 3: Add chicken and base ingredients

Place the chicken breasts in the bottom of the crockpot in a single layer. Scatter the diced onion, bell peppers, black beans, corn, and green chiles over the chicken. Pour about two thirds of the sauce mixture over everything and turn the chicken so the sauce coats it well.

Step 4: Slow cook the chicken

Cover the crockpot with the lid. Cook on high for 2½ to 3 hours or on low for 4 to 5 hours, until the chicken shreds easily with forks. Stir once halfway through if you can, so the veggies and sauce mingle nicely.

Step 5: Shred the chicken

When the chicken feels tender, transfer it to a cutting board or a large bowl. Use two forks to shred it into bite sized pieces. Return the shredded chicken to the crockpot and stir it into the sauce and veggies.

Step 6: Add tortillas and remaining sauce

Cut the corn tortillas into strips or wedges. Add them to the crockpot along with the remaining sauce mixture. Stir everything gently so the tortilla pieces tuck into the saucy chicken mixture and soak up flavor.

Step 7: Add cheese and finish cooking

Sprinkle the shredded cheese evenly over the top of the casserole. Cover the crockpot again and cook on high for 20 to 30 minutes, until the cheese melts and the edges bubble. Turn off the heat and let the casserole sit uncovered for 10 to 15 minutes so it thickens.

Step 8: Garnish and serve

Scoop the Crockpot Chicken Enchilada Casserole Recipe into bowls or onto plates. Add toppings like sour cream, avocado, cilantro, green onions, and a squeeze of lime. Serve it hot and watch everyone go back for seconds.
