This is popular in my family. I don’t measure, so I’ll do my best with approximations.
3 pounds ground beef
1 onion cut in pieces (not diced)
1 Tablespoon or so of butter
2 Eggs
One or two sandwich rolls torn into pieces
1 teaspoon of salt (I am really unsure on this one)
1 teaspoon of pepper (see above)
Ketchup in small batches (maybe up to about 3 cups)
I put some butter in a frying pan and add a pinch of salt and the chopped onion. I cook that over medium heat for 8 minutes or so. Just until the onion starts to turn translucent.
Put everything in a bowl and mix well. Add the ketchup as you mix to get the mixture to the right consistency. Shape into a loaf, pour a good layer of ketchup on top and bake at 350 for about an hour.
It’s pretty basic, but people seem to like it. Even some kids.
