1-2lbs ground beef. (depending of the size of your family, I can still get away with just 1, but 2 will fill your whole loaf pan, and you will want to double the rest of the ingredients also)
1 cup old fashioned oats
1/2 white onion finely chopped
2T ketchup, plus a few squirts on top
Preheat oven to 375. Place the beef into a mixing bow, add egg, oats, onion and ketchup. Mix ingredients. Don't be afraid to get a little messy, because it works best if you do it with your hands. Once well combined place into a loaf pan and pat down so it's pretty even. Squirt a bit of ketchup on top and spread around with the back of a spoon. Bake in your preheated oven for 30-45 minutes until it is browned.
