To create a delicious Chicken Burrito Casserole, follow these simple steps:

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 a little olive oil.
3. Mix the Ingredients: In a large mixing bowl, combine the cooked rice, shredded chicken, black beans, diced tomatoes, corn, taco seasoning, and salsa. Stir until all ingredients are well incorporated.
4. Layer in the Dish: Spread half of the mixture evenly in the bottom of the prepared baking dish.
5. Add Cheese: Sprinkle half of the shredded cheese over the rice and chicken mixture.
6. Add Remaining Mixture: Layer the remaining chicken and rice mixture on top of the cheese.
7. Top with Cheese: Finish by adding the remaining shredded cheese on the top layer.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly.
9. Cool Slightly: Once done, remove the casserole from the oven and let it cool for about 5-10 minutes.
10. Garnish: Before serving, sprinkle chopped green onions and fresh cilantro on top for added flavor and freshness.
