This is a pretty generic meatball recipe, it can be baked, fried or cooked in tomato sauce.
The seasonings are the ones I use when cooking them in tomato sauce, for Swedish meatballs I'd probably use different herbs, like nutmeg.
1 small onion, finely diced
2 tablespoons butter
1 pound ground beef (I usually use 80 or 85% lean)
2 eggs
1/2 cup old fashioned rolled oats
1-2 tablespoons milk
salt
pepper
1/4 teaspoon basil
1/4 teaspoon thyme
Sautee the onions in the butter and allow to cool. Mix all the ingredients thoroughly and shape into meatballs.
Yield: 28 meatballs 1 1/4" in diameter
