Making your Mexican Chicken Casserole is straightforward if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Ingredients: In a large bowl, combine the shredded chicken, salsa, black beans, corn, cream of chicken soup, sour cream, cumin, chili powder, garlic powder, onion powder, salt, and pepper. Mix until well combined.
3. Layer the Casserole: In a greased 9×13 inch baking dish, spread a thin layer of the chicken mixture across the bottom. Place a layer of tortilla quarters on top.
4. Add More Layers: Spoon more chicken mixture over the tortillas, add a layer of cheese, and then continue layering with tortillas, chicken mixture, and cheese until all ingredients are used, finishing with a layer of cheese on top.
5. Bake the Casserole: Cover the baking dish with foil and bake for 20-25 minutes. Then, remove the foil and bake for an additional 10-15 minutes or until the cheese is bubbly and golden.
6. Cool: Once out of the oven, let it cool for about 5 minutes before serving. This helps the casserole set.
7. Garnish: Optional – sprinkle fresh cilantro or chopped green onions on top before serving for a pop of color and flavor.

With these steps, you’ll find that making the perfect Mexican Chicken Casserole is incredibly doable!
