01 - Preheat oven to 400°F. Lightly grease a baking dish with olive oil.
02 - Pat the chicken breasts dry with paper towels and season both sides generously with salt and black pepper.
03 - Place the seasoned chicken breasts in a single layer in the prepared baking dish.
04 - In a medium mixing bowl, combine the ricotta cheese, Parmesan cheese, half of the mozzarella, minced garlic, chopped parsley, basil, dried oregano, and crushed red pepper flakes. Stir until thoroughly blended.
05 - Divide and spread the ricotta herb mixture evenly over each chicken breast. Sprinkle the remaining mozzarella cheese on top of each portion.
06 - Drizzle the olive oil over the topped chicken breasts to promote browning and moisture retention.
07 - Bake for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the tops are golden brown.
08 - Remove from the oven, garnish with additional chopped parsley, and serve hot. Offer warmed marinara sauce on the side if desired.
