How to Make Slow Cooker Chicken Enchilada Casserole

Step 1: Prepare the Slow Cooker

Prepare the liner of the slow cooker with nonstick cooking spray. This helps prevent sticking and makes it easier to serve.

Step 2: Add Chicken and Seasonings

Place the chicken breasts into the bottom of the slow cooker. Over the chicken, sprinkle taco seasoning, salt, and black pepper evenly.

Step 3: Pour in Sauces

Pour both cans of enchilada sauce and the drained tomatoes with diced green chiles over the seasoned chicken. Ensure all pieces are covered.

Step 4: Cook Low and Slow

Cover the slow cooker. Cook on low heat for about 4 to 5 hours until the chicken is tender and cooked through.

Step 5: Prepare Tortillas

While waiting for the chicken to cook, cut corn tortillas into wedges using a sharp knife. Set aside.

Step 6: Shred Chicken

Once cooked, take two forks to shred the chicken directly in the slow cooker. Stir it into the sauce mixture until well combined.

Step 7: Add Tortillas and Cheese

Stir half of the tortilla wedges into the shredded chicken mixture along with half of the shredded cheese. Mix until evenly distributed.

Step 8: Layer Casserole

Press down on mixture gently to create an even layer. Top with remaining tortilla wedges in an overlapping pattern. Sprinkle with remaining cheese on top.

Step 9: Finish Cooking

Re-cover the slow cooker and continue cooking for an additional 30 minutes until heated through and cheese is melted.
