In a large bowl, mix together the chicken, egg, Parmesan cheese, breadcrumbs, garlic powder, Italian seasonings, salt, pepper, and red pepper. Roll into 1 1/2 inch balls.
Heat 2 tablespoons oil in a large oven-safe skillet over medium heat. Roll half of the meatballs in Panko breadcrumbs and brown them on each side in the oil. Add more oil if needed as you go. Remove from the pan and set aside. Wipe out any Panko breadcrumbs and heat the remaining 2 tablespoons of olive oil over medium heat. Roll the remaining meatballs in Panko breadcrumbs and brown on each side. Remove from pan.
Preheat oven to 350 degrees. Pour marinara sauce in the oven-safe skillet (or any baking dish will do) and place the meatballs on top of the sauce. Bake meatballs for 20 minutes sprinkling the mozzarella on top for the last 5 minutes of baking. Garnish with basil and serve over pasta.
