Creating Cheesy Baked Chicken Breast and Peppers is a breeze when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Baking Dish: Lightly grease a baking dish with cooking spray or a little olive oil.
3. Season Chicken: Pat the chicken breasts dry with a paper towel. Season both sides with garlic powder, onion powder, oregano, salt, and pepper.
4. Sauté Peppers: In a skillet, heat olive oil over medium heat. Add the sliced bell peppers and sauté for about 5 minutes until they start to soften. Remove from heat.
5. Arrange Chicken: Place the seasoned chicken breasts in the prepared baking dish in a single layer.
6. Add Peppers: Evenly spread the sautéed bell peppers over the chicken breasts.
7. Add Cheese: Sprinkle shredded mozzarella and Parmesan cheese generously over the top of the peppers and chicken.
8. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
9. Check for Doneness: Use a meat thermometer to ensure the chicken has reached an internal temperature of 165°F (75°C).
10. Garnish: Once done, remove from the oven and let it rest for a few minutes. Garnish with freshly chopped parsley before serving.

These steps will help you create a delicious and hearty meal that your family and friends will enjoy.
