Description

Slow Cooker French Onion Meatballs combine the rich, savory flavors of classic French onion soup with tender beef meatballs, topped with melted Gruyere cheese. Perfectly cooked in a slow cooker for effortless preparation and a comforting, hearty meal.


Ingredients

Scale

Meatballs

  • 26 oz bag frozen beef meatballs

Sauce and Topping

  • 1 large yellow onion, peeled and thinly sliced
  • 2 cans (10.5 oz each) condensed French onion soup (Campbell’s brand recommended)
  • 1 cup shredded Gruyere cheese (freshly shredded preferred for better melt-ability)


Instructions

  1. Prepare Ingredients: Peel and thinly slice the large yellow onion to ensure it cooks evenly and releases its sweet flavor during slow cooking.
  2. Layer Meatballs and Onions: Place the frozen beef meatballs into the slow cooker, then add the sliced onions evenly over the top.
  3. Add Soup: Pour the two cans of condensed French onion soup over the meatballs and onions, distributing it evenly to cover everything for maximum flavor.
  4. Cook: Set the slow cooker on low and cook for approximately 3.5 hours (210 minutes), allowing the meatballs to become tender and the flavors to meld perfectly.
  5. Add Cheese and Finish: About 10 minutes before serving, sprinkle the shredded Gruyere cheese over the meatballs and close the lid to let the cheese melt thoroughly.
  6. Serve: Once the cheese has melted, serve the French Onion Meatballs hot as a delicious appetizer or main dish with your favorite sides.

Notes

  • Everything you love about classic French onion dip is combined with meatballs and made effortlessly in the slow cooker.
  • Using freshly shredded Gruyere cheese improves melting and texture compared to pre-shredded cheese.
  • You can substitute homemade French onion soup for the canned version if preferred.
  • This dish pairs wonderfully with crusty bread or over buttery egg noodles for a complete meal.
