Preheat the oven to 425 degrees. Spray a baking sheet with cooking spray (cover with foil for easier clean up). Combine the panko breadcrumbs, Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper.
Press one side of the chicken into the egg and then into the panko and Parmesan mixture. Place it on the baking sheet with the breading up. To make it extra crispy, spray the chicken with cooking spray or drizzle with a little olive oil.
