Another family favorite growing up. Gotta love the tater tots!
2 lbs. ground beef
1 large bag tater tots
2 cups grated cheddar cheese
1 onion, chopped
1 can cream of mushroom soup
1 can of milk (Use soup can to measure out)
Brown the beef and onion. Drain grease. Whip soup and milk together. Set aside. Layer beef, tater tots, cheese and half of soup mixture. Repeat layers. Top with cheese and bake at 350 for 1 hour.
