This is a generously sized casserole and will fill a standard 9x13-inch baking dish nearly to the top. If your family loves pepperoni, don't be shy about adding extra. Mine immediately requested more the next time I made it! I also recommend using both marinara sauce and pizza sauce, which is the secret to making this taste like pizza instead of baked spaghetti.
