Preheat the air fryer to 400°F. Season chicken breasts with salt and pepper. Set up a breading station with flour, beaten eggs, and seasoned Panko breadcrumbs mixed with Parmesan, garlic powder, oregano, and basil.
Transfer to a baking sheet, top with marinara sauce and shredded mozzarella, then broil for 2-3 minutes until cheese is melted. Serve hot, garnished with fresh parsley if desired.
