Description

Savor the rich and comforting flavors of Slow Cooker French Onion Meatballs, combining tender beef meatballs with caramelized onions and savory French onion soup, topped with melted Gruyere cheese. This easy slow cooker recipe is perfect for a satisfying meal with minimal effort.


Ingredients

Scale

Main 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 (Campbell’s recommended)
  • 1 cup shredded Gruyere cheese (preferably freshly shredded for better melt-ability)


Instructions

  1. Prepare the Ingredients: Peel and thinly slice the large yellow onion to ensure it cooks evenly and releases its natural sweetness during slow cooking.
  2. Layer Ingredients in Slow Cooker: Place the frozen beef meatballs into the slow cooker. Spread the sliced onions evenly over the meatballs.
  3. Add French Onion Soup: Pour the two cans of condensed French onion soup evenly over the meatballs and onions, which will add rich flavor and moisture to the dish.
  4. Cook on Low: Cover the slow cooker and cook on low heat for about 3.5 hours (210 minutes) to allow the onions to caramelize slowly and the meatballs to become tender and infused with the soup’s flavor.
  5. Add Gruyere Cheese: About 10-15 minutes before serving, sprinkle the shredded Gruyere cheese over the meatballs. Cover and let the cheese melt, creating a creamy, golden topping.
  6. Serve Warm: Once the cheese has melted, gently stir if desired and serve the meatballs hot as a main dish, appetizer, or party snack.

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 flavor compared to pre-shredded cheese.
  • For softer onions, slice them thinner or cook longer on low heat.
  • This recipe can be doubled and cooked in a larger slow cooker for more servings.
  • Serve with crusty bread or over egg noodles for a hearty meal.
