Creating Chicken Enchilada Rice Casserole can be simple if you follow these easy steps:

1. Preheat Your Oven: Set your oven to 350°F (175°C) to prepare for baking.
2. Prepare the Baking Dish: Grease a 9×13-inch casserole dish to prevent sticking.
3. Mix Ingredients: In a large mixing bowl, combine the cooked rice, shredded chicken, black beans, enchilada sauce, salsa, cumin, garlic powder, onion powder, salt, and pepper. Stir well until evenly mixed.
4. Layer the Mixture: Spread half of the rice and chicken mixture evenly into the prepared casserole dish, smoothing the top.
5. Add Cheese: Sprinkle 1 cup of the shredded cheese over the first layer.
6. Top with Remaining Mixture: Add the remaining rice and chicken mixture on top, spreading it evenly.
7. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and sprinkle the remaining cheese on top.
8. Continue Baking: Return to the oven and bake uncovered for an additional 10-15 minutes, or until the cheese is bubbly and golden brown.
9. Cool Briefly: Remove from the oven and allow it to cool for a few minutes before serving. This helps the casserole set up nicely.
10. Prepare for Serving: Slice into squares and add any optional toppings you desire.
