Instructions:
- Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with cooking spray.
- In a large bowl, mix together the shredded chicken, red enchilada sauce, green enchilada sauce, sour cream, green chilies, black beans, corn, cumin, garlic powder, salt, and black pepper until well combined.
- Layer the bottom of the prepared baking dish with a few spoonfuls of the chicken mixture.
- Place a layer of corn tortillas over the chicken mixture, tearing them as needed to cover the bottom of the dish.
- Spoon about one-third of the remaining chicken mixture over the tortillas, spreading it out evenly.
- Sprinkle a third of the shredded cheese over the chicken mixture.
- Repeat the layers of tortillas, chicken mixture, and cheese two more times, ending with a final layer of cheese on top.
- Cover the baking dish with foil and bake in the preheated oven for 30 minutes.
- Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
- Remove the casserole from the oven and let it cool for a few minutes before serving.
- Serve the Sour Cream Chicken Enchilada Casserole hot, topped with your favorite toppings such as chopped cilantro, sliced green onions, diced tomatoes, sliced olives, and additional sour cream if desired.
