Preheat the oven to 375°F (190°C).
Lightly grease a baking dish with olive oil.
Pat the chicken breasts dry with paper towels and place them in the prepared baking dish.
In a small bowl, mix together the garlic powder, onion powder, dried Italian seasoning, salt, and black pepper.
Sprinkle the seasoning mixture evenly over both sides of each chicken breast.
In another bowl, combine the shredded mozzarella cheese, grated Parmesan cheese, chopped fresh parsley, and breadcrumbs.
Sprinkle the cheese and breadcrumb mixture evenly over the top of each seasoned chicken breast.
Drizzle the tablespoon of olive oil evenly over the chicken breasts to help the topping brown.
Bake in the preheated oven for 25 to 30 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).
Remove from the oven and let the chicken rest for 5 minutes before serving.
