3. Transfer caramelized onions to the crock pot.
4. Add frozen meatballs, Worcestershire sauce, French onion soup, and beef broth. Stir to combine.
5. Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until meatballs are heated through and flavors have melded.

7. Garnish with parsley and serve hot with bread, rice, or noodles.

For homemade meatballs, brown them before adding to the crock pot for extra flavor.
