1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prep Baking Dish: Lightly grease a 9×13 inch baking dish to prevent sticking.
3. Make Filling: In a large bowl, combine the cooked shredded chicken, black beans, corn, half of the enchilada sauce, cumin, chili powder, and onion. Mix well and season with salt and pepper to taste.
4. Layer the First Tortilla: Place 2 tortillas on the bottom of the prepared dish, slightly overlapping them if necessary.
5. Add Filling: Spoon half of the chicken filling over the tortillas. Spread evenly.
6. Add Cheese: Sprinkle a portion of the cheddar and Monterey Jack cheese over the filling.
7. Layer the Next Tortillas: Repeat the layering process with 2 more tortillas, the remaining filling, and more cheese.
8. Final Layer: Top with the last 2 tortillas and pour the remaining enchilada sauce over the top, ensuring coverage.
9. Top with Cheese: Finish with the remaining cheese, creating a melty topping.
10. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden brown.
11. Cool Down: Once baked, remove from the oven and let cool for 5-10 minutes before cutting into portions.
