- beef, breadcrumbs, Parmesan cheese, parsley, egg, garlic, onion powder, Italian herbs, salt, pepper, and red pepper flakes (if using).

- Place in Baking Dish: Arrange the meatballs in a single layer in a greased baking dish. Make sure they are close together but not touching, as they will expand
