Creating a Chicken Fajita Casserole is an easy-to-follow process that yields a satisfying meal. Here’s a list of steps to guide you through preparing this dish:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Prepare the Baking Dish: Grease a 9×13 inch baking dish with cooking spray or olive oil to prevent sticking.
3. Sauté the Vegetables: In a large skillet, heat a tablespoon of olive oil over medium heat. Add the sliced bell pepper and onion, sautéing until they are tender, about 5-7 minutes.
4. Combine Ingredients: In a large bowl, mix the shredded chicken, black beans, diced tomatoes (with juices), corn, sautéed peppers and onions, taco seasoning, garlic powder, cumin, paprika, salt, pepper, and sour cream until well combined.
5. Layer the Tortillas: Place half of the tortilla strips at the bottom of the prepared baking dish, spreading them out evenly.
6. Add the Chicken Mixture: Spoon the chicken mixture over the tortilla strips, spreading it out evenly.
7. Top with Cheese: Sprinkle one cup of shredded cheese over the chicken layer.
8. Finish with Tortillas: Add the remaining tortilla strips on top of the Cheese layer.
9. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and sprinkle the remaining cheese on top. Bake for another 10-15 minutes, or until cheese is bubbly and golden.
10. Cool and Serve: Remove the casserole from the oven and let it cool for a few minutes before slicing and serving.

With these simple steps, you’ll have a flavorful Chicken Fajita Casserole that is sure to impress!
