Ingredients

Scale

Meatballs

  • 1 pound ground beef
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1 egg
  • 1 onion, finely chopped
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper

Sauce and Topping

  • 2 cups beef broth
  • 1 packet French onion soup mix (about 1.25 ounces)
  • 1 cup shredded mozzarella cheese

Instructions

  1. Prepare the meatball mixture: In a large bowl, thoroughly combine the ground beef, breadcrumbs, grated Parmesan cheese, egg, finely chopped onion, garlic powder, salt, and black pepper until evenly mixed.
  2. Form the meatballs: Shape the mixture into evenly sized meatballs, approximately 1 to 1.5 inches in diameter for even cooking.
  3. Place meatballs in crockpot: Arrange the formed meatballs in a single layer inside the crockpot to ensure even cooking.
  4. Mix the broth and soup mix: In a separate bowl, whisk together the beef broth and the packet of French onion soup mix until fully combined.
  5. Pour sauce over meatballs: Carefully pour the beef broth and soup mixture over the meatballs in the crockpot, covering them evenly.
  6. Cook the meatballs: Cover the crockpot with the lid and cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the meatballs are cooked through and tender.
  7. Add cheese topping: Sprinkle the shredded mozzarella cheese evenly over the cooked meatballs and cover the crockpot again.
  8. Melt the cheese: Continue cooking for an additional 15 minutes on low or until the cheese is melted and bubbly.

Notes

  • For best flavor, use fresh grated Parmesan and freshly shredded mozzarella cheese.
  • You can substitute ground turkey or chicken for a leaner option, but cooking times may vary slightly.
  • If you don’t have a crockpot, this recipe can be adapted to a low oven bake covered in a covered baking dish at 300°F for 1.5 to 2 hours.
  • Serve with crusty bread or over egg noodles for a complete meal.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated gently.
