Ingredients
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
- 1 cup shredded mozzarella cheese
Instructions
- 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.
- Form Meatballs: Shape the mixture into uniform meatballs, about 1 to 1.5 inches in diameter, to ensure even cooking.
- Place Meatballs in Crockpot: Arrange the formed meatballs evenly inside the crockpot, creating a single layer without overcrowding.
- Prepare Sauce: In a separate bowl, whisk together the beef broth and the French onion soup mix until fully combined.
- Add Sauce to Crockpot: Pour the broth and soup mix mixture over the meatballs in the crockpot, making sure they are mostly submerged to allow thorough simmering.
- Cook Meatballs: Cover the crockpot with its lid and cook on low heat for 6-8 hours or on high heat for 3-4 hours until the meatballs are fully cooked and tender.
- Add Cheese: Sprinkle the shredded mozzarella cheese evenly over the meatballs in the last 15 minutes of cooking, allowing it to melt beautifully over the top.
- Serve: Once the cheese is melted and bubbly, turn off the crockpot and serve the meatballs hot, spooning some of the flavorful sauce over each portion.
Notes
- For best results, use fresh onions finely chopped to enhance flavor and texture.
- Breadcrumbs help bind the meatballs, but panko breadcrumbs can be used for a lighter texture.
- The French onion soup mix adds an authentic savory flavor; consider low-sodium broth to control saltiness.
- Leftovers can be refrigerated for up to 3 days or frozen for longer storage.
- Serve over mashed potatoes, rice, or noodles for a complete meal.
