01 - Preheat oven to 400°F. Lightly grease a baking dish large enough to accommodate the chicken breasts in a single layer.
02 - Pat chicken breasts dry with paper towels 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 medium bowl, combine ricotta, Parmesan, mozzarella, minced garlic, parsley, basil, onion powder, lemon zest, and chili flakes if using. Season with salt and pepper. Mix thoroughly until all ingredients are evenly distributed.
04 - Spread the ricotta mixture generously over each chicken breast, ensuring the tops are evenly covered.
05 - Drizzle the remaining 1 tablespoon olive oil over the ricotta-topped chicken breasts.
06 - Bake uncovered for 25-30 minutes until chicken reaches an 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.
