I recently learned this secret to a great tasting meatloaf.
1 1/2 - 2 lbs lean ground beef
Mix ground beef with a variety of other ingredients like:
(I add whatever I have on hand.)
fresh or dried bread crumbs
diced onion, celery, green pepper, garlic
sliced green onion
salt and pepper
Press into loaf pan.
Put a layer brown sugar on top of meatloaf
Then a layer of ketchup.
Bake at 350 for about 1 hour or until done depending on size of meatloaf.
