Here’s how to create your Chicken Burrito Casserole step-by-step:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).

2. Prep the Casserole Dish: Lightly grease a 9×13-inch baking dish with cooking spray or oil.

3. Mix Chicken and Beans: In a large bowl, combine the cooked chicken, black beans, corn, diced tomatoes, salsa, sour cream, cumin, and chili powder. Stir until well mixed.

4. Layer Tortillas: Spread a layer of tortilla strips evenly across the bottom of the prepared baking dish.

5. Add Chicken Mixture: Spoon half of the chicken mixture over the tortilla layer, spreading it out evenly.

6. Repeat the Layers: Add another layer of tortilla strips, followed by the remaining chicken mixture. Finish with a top layer of tortilla strips.

7. Top with Cheese: Sprinkle the shredded cheese over the top layer of tortillas, making sure it’s evenly distributed.

8. Bake the Casserole: Cover the baking dish with aluminum foil and bake for 20 minutes in the preheated oven. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.

9. Let it Cool: Remove from the oven and let the casserole cool for about 5 minutes to set.

10. Garnish: Before serving, garnish with fresh cilantro and sliced green onions, if desired.
