These Crock Pot French Onion Meatballs are tender, flavorful, and cooked in a rich, savory broth. Made with frozen meatballs and infused with French onion soup and melted mozzarella, this easy slow cooker meal is perfect for busy weeknights or casual gatherings.

Ingredients

  • 24 ounce bag frozen beef homestyle meatballs (a little more or less is fine)
  • 10.5 ounce can French Onion Soup (low sodium)
  • 1 packet French onion soup mix (or beefy onion soup mix)
  • 1 cup beef broth (low sodium)
  • 1 cup shredded mozzarella cheese (more to taste)
  • Fresh thyme or parsley (optional, for garnish)
  • Optional for thickening: 2 tablespoons corn starch + 1/4 cup water

Instructions

  1. Place the frozen meatballs in a single layer in the bottom of a 4–6 quart crock pot.
  2. Pour the can of French Onion Soup over the meatballs.
  3. Sprinkle the French onion soup mix over the top, then pour in the beef broth.
  4. Cover and cook on high for 2–3 hours or low for 5–6 hours.
  5. Optional: To thicken the sauce, mix corn starch and water in a small bowl to form a slurry. Stir the slurry into the crock pot, cover, and cook for an additional 10 minutes.
  6. Sprinkle shredded mozzarella cheese evenly over the meatballs. Cover and cook until the cheese is melted.
  7. Garnish with fresh thyme or parsley if desired. Serve hot over mashed potatoes or egg noodles.

Notes

  • Use low or no sodium versions of canned soup and broth to keep the dish from becoming too salty.
  • These meatballs pair well with mashed potatoes, egg noodles, or a side of green beans.
  • The slurry step is optional but helps thicken the sauce into a gravy consistency.
