Ingredients

Ingredients for Crock Pot French Onion Meatballs

  • 1 (32 oz) bag of frozen homestyle meatballs
  • 2 (10.5 oz) cans of condensed French onion soup
  • 1 packet (1 oz) of dry onion soup mix
  • 1 cup shredded Gruyère or mozzarella cheese
  • 1 tbsp cornstarch (optional, for thickening)
  • 2 tbsp water (for mixing with cornstarch)

Tip: Gruyère is traditional and melts beautifully, but mozzarella is a great substitute. If you’re looking for more cheesy goodness, try these Garlic Parmesan Chicken Skewers.

Instructions

  1. Layer the meatballs: Place the frozen meatballs into your slow cooker insert. No need to thaw—just dump them in.
  2. Add the soups: Pour both cans of French onion soup over the meatballs. Sprinkle the dry onion soup mix evenly on top.
  3. Cook low and slow: Cover and cook on LOW for 4–6 hours or on HIGH for 2–3 hours. Stir halfway through if possible.
  4. Thicken the sauce (optional): In the last 30 minutes of cooking, if you’d like a thicker sauce, mix 1 tbsp cornstarch with 2 tbsp water and stir into the pot.
  5. Add cheese: Sprinkle the shredded cheese over the top of the meatballs. Cover and let cook for another 15–20 minutes until the cheese is melted and gooey.
  6. Serve and enjoy: Serve hot as-is or over mashed potatoes, pasta, rice, or on toasted buns. For another hearty option, check out Cottage Cheese Egg Salad for a side dish.

Notes

  • Use good quality meatballs: Store-bought homestyle meatballs work well, but premium brands offer better flavor.
  • Don’t skip the cheese: It creates a melty top layer that mimics classic French onion soup.
  • Stir gently: If stirring mid-cook, do so gently to keep meatballs intact.
  • Use slow cooker liners: For stress-free cleanup at potlucks and camping.
  • Prep Time: 5 minutes
  • Cook Time: 4–6 hours (LOW) / 2–3 hours (HIGH)
