Creating the perfect Baked Boneless Chicken Breast is simple when you follow these steps:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Prepare the Chicken: Pat the chicken breasts dry with paper towels. This helps achieve a nice sear and prevents steaming.
3. Make the Marinade: In a small bowl, mix the olive oil, garlic powder, onion powder, paprika, oregano, salt, black pepper, and chili powder (if using).
4. Coat the Chicken: Rub the marinade all over the chicken breasts, ensuring they are evenly coated.
5. Arrange in Baking Dish: Place the seasoned chicken breasts in a baking dish, making sure they are not overcrowded.
6. Bake the Chicken: Transfer the baking dish to the preheated oven and bake for 25-30 minutes, or until the internal temperature reaches 165°F (75°C).
7. Rest the Chicken: Once cooked, remove the chicken from the oven and let it rest for 5 minutes. This step is essential for keeping the juices locked in.
8. Slice and Serve: After resting, slice the chicken breasts against the grain and serve immediately.

Following these steps will ensure that your Baked Boneless Chicken Breast turns out tender and flavorful every time.
