Meatloaf is essentially ground meat mixed with seasonings before cooking. It can be shaped into a loaf form or baked in a loaf pan. Some of the add-ins include onion, garlic, herbs, and ketchup. To help hold the meatloaf together binders such as eggs, breadcrumbs or even oatmeal are used. Meatloaf can be made with beef, pork, turkey, lamb, or a mixture like in my meatloaf recipe.
