Creating Southwestern Baked Chicken is straightforward if you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare Chicken: Rinse the chicken breasts under cold water and pat them dry with paper towels.
3. Season Chicken: In a small bowl, mix together chili powder, cumin, garlic powder, onion powder, paprika, salt, and black pepper. Rub this spice mixture all over the chicken breasts.

8. Bake: Transfer the skillet to the preheated oven and bake for 30-35 minutes, or until the internal temperature of the chicken reaches 165°F (74°C).
9. Rest the Chicken: Once fully cooked, remove the skillet from the oven and allow the chicken to rest for about 5 minutes.
10. Garnish and Slice: If desired, garnish with fresh cilantro and serve with lime wedges.
