Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This guarantees that your dish will be cooked uniformly throughout.
Prepare the Chicken: In a large bowl, drizzle the olive oil over the chicken breasts. Sprinkle with garlic powder, onion powder, ground cumin, chili powder, paprika, salt, and black pepper. Use your hands or a spoon to coat the chicken evenly with the spices.
Layer the Salsa: Place the seasoned chicken breasts in a baking dish. Pour half of the salsa (1/2 cup) evenly over the top of the chicken, ensuring each piece is well-covered.
Add the Cheese: Sprinkle the mozzarella and cheddar cheese generously over the salsa-covered chicken. Then, pour the remaining salsa on top of the cheese for extra flavor.
Bake: Cover the baking dish with aluminum foil to prevent the cheese from browning too quickly. Place in the preheated oven and bake for approximately 25 to 30 minutes. Remove the foil and continue baking for an additional 10-15 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
Garnish and Serve: Once baked, remove the dish from the oven and let it sit for a few minutes. Garnish with freshly chopped cilantro before serving. This meal complements perfectly with rice, quinoa, or a crisp salad.
