Creating this amazing Southwestern Baked Chicken can be effortless if you follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare Chicken: Pat the chicken breasts dry with paper towels. This helps the seasoning stick better.
3. Season Chicken: In a small bowl, mix together chili powder, cumin, paprika, garlic powder, onion powder, salt, and black pepper. Rub the olive oil over the chicken, then coat it evenly with the spice mixture.
4. Place in Baking Dish: Arrange the seasoned chicken breasts in a single layer in a baking dish.
5. Add Vegetables: In a bowl, combine black beans, corn, and diced tomatoes. Pour this mixture over the chicken in the baking dish, spreading it evenly.
6. Cover and Bake: Cover the dish tightly with aluminum foil and bake for 25-30 minutes.
7. Add Cheese: After 30 minutes, carefully remove the foil and sprinkle the shredded cheese generously over the top.
8. Finish Baking: Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly, and the chicken is fully cooked (internal temperature should reach 165°F or 75°C).
9. Rest the Chicken: Once done, remove the dish from the oven and let it rest for 5 minutes. This helps the juices redistribute.
10. Garnish and Serve: Sprinkle fresh cilantro over the top and serve with lime wedges on the side.
