Ingredients

Scale

Meatballs

  • 1 ½ pounds ground beef
  • ½ cup breadcrumbs
  • 1 large egg
  • 2 cloves garlic, minced
  • Salt and pepper to taste

French Onion Sauce

  • 1 package (1 oz) onion soup mix
  • 1 cup beef broth

Topping

  • 1 cup shredded Swiss or mozzarella cheese

Instructions

  1. Prepare the Meatballs: In a large bowl, combine the ground beef, breadcrumbs, egg, minced garlic, salt, and pepper. Mix thoroughly until all ingredients are well incorporated. Form the mixture into 1-inch meatballs and set aside.
  2. Prepare the Onion Sauce: In a separate bowl, whisk together the onion soup mix and beef broth until well combined, ensuring the soup mix dissolves completely.
  3. Slow Cook the Meatballs: Place the meatballs evenly in the crock-pot. Pour the onion soup mixture over the meatballs, making sure they are mostly covered. Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the meatballs are cooked through and tender.
  4. Add Cheese Topping: About 15 minutes before serving, sprinkle shredded Swiss or mozzarella cheese evenly over the meatballs. Cover the crock-pot again and allow the cheese to melt, creating a bubbly, golden topping.
  5. Serve: Carefully scoop the meatballs with the onion sauce onto plates or a serving dish. Serve hot as a main dish accompanied by mashed potatoes, rice, or crusty bread.

Notes

  • For extra flavor, caramelize onions separately and add them to the crock-pot.
  • Ground turkey or chicken can be used as a leaner alternative to beef.
  • If you prefer a thicker sauce, remove the lid during the last 30 minutes of cooking to let some liquid evaporate.
  • Cheese options can be varied—Gruyere or provolone also pair well with French onion flavors.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
