Ingredients

  • 36 ounce frozen meatballs
  • 2 large sweet onions thinly sliced into half moons
  • 3-5 garlic cloves minced
  • 2 cups low sodium beef broth
  • 1 10.5 oz can condensed French onion soup
  • 1 tablespoon balsamic vinegar
  • 1 ½ teaspoons fresh thyme minced
  • ¾ teaspoon black pepper to taste
  • 2 tablespoons cornstarch
  • 1 cup shredded Gruyere cheese
  • Fresh thyme or parsley for garnish (optional)

Instructions

  • Place frozen meatballs in crockpot.
  • Top with sliced onions and minced garlic.
In a mixing bowl or large measuring cup, combine the beef broth, French onion soup, balsamic vinegar, thyme, black pepper, and cornstarch. Whisk well to combine.
  • Pour mixture over the meatballs, onions, and garlic.
  • Cover with lid and cook on LOW for 3-5 hours, until the meatballs are fully heated through. Stir halfway through cooking time to ensure even heating and to make sure the sauce is not burning on the bottom of the pan.
  • Right before serving, top the meatballs with the shredded gruyere cheese. Cover with lid and cook for an additional 5-10 minutes, until the cheese is fully melted.
  • Garnish with fresh chopped parsley or thyme if desired. Serve as an appetizer or over mashed potatoes or egg noodles. Enjoy!
