Meatloaf is a basic recipe that many people enjoy. There are several different ways to make a meatloaf. I think to make it called a meatloaf, it needs a sauce on top and a filler and eggs in with the ground beef. There are still so many different variations it is difficult to determine what is a standard meatloaf recipe? Did it originate with a tomato sauce on top or should it be a gravy sauce on the top? Should it have breadcrumbs, crackers, or oatmeal for the filler? There are so many delicious options out there.
