I couldn't find a recipe on this site (or elsewhere) for basic meatloaf with caramelized onions in the mix-not meatloaf with a topping of caramelized onions or "stuffed". Because I wanted the caramelized onions to take center stage, for that reason, you won't find any tomato sauce, mushrooms, no cheese, no strips of bacon on top, etc. in this recipe. The recipe was found on lifeisaplate.com and modified to my specifications. You can substitute other types of ground meat or use other meat in combination: turkey, chicken, buffalo, turkey, etc. Use any preferable binder of your choice, for example-finely ground breadcrumbs, almond or walnut meal, masa harina, rice flour. Brown rice was the binder I chose and it was ground to medium-coarse consistency (similar to cornmeal). The recipe was cut in half because I like meatloaf on the small size and save the larger size when I am need of a doorstop.
