Ingredients

  • 26 oz bag frozen beef meatballs
  • 1 large yellow onion peeled and thinly sliced
  • 2 cans (10.5 oz each) condensed French onion soup we like Campbells brand
  • 1 cup shredded gruyere cheese we prefer to shred our own (better melt-ability)

Instructions

Prepare

  • Add frozen meatballs to the insert of your slow cooker.

Add onion and soups

  • To the slow cooker, add the sliced onion and both cans of french onion soup.
  • Stir to combine.

Cook

  • Cover and cook on LOW for 3 - 4 hours, or on HIGH for 1 - 2 hours. While meatballs are cooking, I like to stir them every so often to make sure the sauce isn't burning.

Add cheese

  • The last 15-30 minutes before serving, sprinkle with the shredded cheese. Return the lid back to the slow cooker and continue to cook, covered, until cheese is melted.

Serve

  • Serve hot, over mashed potatoes, toasted slices of french bread, or rice.

Notes

  1. I've estimated this recipe serves 4, but please feel free to divide it into as many servings as you'd like.
  2. This recipe works with a bag of frozen meatballs that range from 26-32 oz.
  3. I haven't tested using any other types of french onion soup (non condensed, packets of onion soup, etc), so I can't say how well it would work. If you do some experimenting, I'd love to know how it goes!
