Preheat your oven to 400°F (200°C). Lightly grease a baking dish with cooking spray or olive oil.
In a mixing bowl, combine the grated Parmesan cheese, breadcrumbs, minced garlic, dried Italian herbs, salt, and black pepper. Mix well.
Drizzle the olive oil over the chicken breasts, ensuring they are evenly coated. Then, dip each chicken breast in the cheese and breadcrumb mixture, pressing down lightly to ensure the coating adheres well.
Place the coated chicken breasts in the prepared baking dish, spaced apart.
Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and the topping is golden brown. The internal temperature of the chicken should reach 165°F (74°C).
Once done, remove from the oven and let rest for a few minutes. Garnish with chopped parsley before serving.
