I cheat when making meatballs for my family. In general we buy the vegetarian frozen meatballs (ideal!) or regular frozen meatballs. Some good, some bad.
I grew up making a lot of meatballs with Lipton California Onion Soup Mix. I don’t think they call it California anymore but they did in the 70s.
Basically, here was the deal. You grab a kid (because who wants to touch cold raw hamburger, right?). Make kid wash hands.
Take 2 lbs of fairly lean ground beef, 1 packet of Lipton Onion Soup mix, an egg, and about 1 cup of dry bread crumbs. Combine the ingredients. Roll into small balls…then BAKE them. Yes, bake them. Oh, you can microwave them too, but if you are doing a fair sized batch, just toss them on your cookie sheet…err Jelly Roll pan. (not a real cookie sheet with no edges to prevent a grease fire in the bottom of the oven) Bake until done-usually 15-20 minutes for a normal party sized meatball.
Then you can use the other packet of onion soup mix and make a lovely, yummy, sauce like I do…and shared in this recipe: Mama’s Meatballs.
