2 cups French onion soup (store-bought or homemade)
1 cup shredded mozzarella cheese
Instructions
Make the Meatballs In a large bowl, mix together the ground beef, breadcrumbs, Parmesan, egg, garlic powder, chopped onion, salt, and pepper until just combined. Don’t overmix!
Form the Meatballs Roll the mixture into 1- to 1½-inch balls and place them in the bottom of your Crock Pot.
Add the Soup Pour the French onion soup evenly over the meatballs.
Slow Cook Cover and cook on LOW for 5–6 hours or HIGH for 2½–3 hours, until meatballs are fully cooked and tender.
Add Cheese About 15 minutes before serving, sprinkle mozzarella cheese over the top. Cover and let it melt into gooey deliciousness.
Serve Spoon meatballs and broth into bowls or over mashed potatoes, rice, or toasted bread. Optional: garnish with extra Parmesan or chopped parsley.
