01 - Preheat oven to 400°F. Lightly grease a baking dish large enough to fit the chicken breasts in a single layer.
02 - Pat chicken breasts dry and season both sides generously with salt and pepper. Arrange in the prepared baking dish and drizzle with 1 tablespoon olive oil.
03 - In a bowl, combine ricotta, Parmesan, mozzarella, garlic, parsley, basil, onion powder, lemon zest, and chili flakes. Season with salt and pepper. Mix until thoroughly incorporated.
04 - Spread the ricotta mixture generously over each chicken breast, ensuring even coverage across the tops.
05 - Drizzle the remaining 1 tablespoon olive oil over the ricotta topping.
06 - Bake uncovered for 25 to 30 minutes until chicken reaches internal temperature of 165°F and the topping is golden brown and bubbling.
07 - Let the chicken rest for 5 minutes before serving. Garnish with additional fresh parsley and serve hot.
