Slow Cooker French Onion Meatballs Recipe

Ingredients:

• 1 lb ground beef
• 1 packet French onion soup mix
• 1/2 cup breadcrumbs
• 1/4 cup milk
• 1 egg
• 1/2 cup grated Parmesan cheese
• 2 tablespoons olive oil
• 2 large onions, thinly sliced
• 2 cups beef broth
• 1 tablespoon Worcestershire sauce
• Salt and pepper to taste
• Fresh thyme for garnish

Directions:

1. Prepare Meatball Mixture: In a large bowl, combine the ground beef, French onion soup mix, breadcrumbs, milk, egg, and grated Parmesan cheese. Mix until all the ingredients are well incorporated. Form the mixture into meatballs, ensuring they are evenly sized for consistent cooking.

2. Brown Meatballs: Heat the olive oil in a skillet over medium heat. Once hot, add the meatballs and brown them on all sides. This step helps lock in flavor and gives the meatballs a delicious crust. After browning, transfer the meatballs to the slow cooker.

3. Caramelize Onions: In the same skillet, add the sliced onions and cook over medium heat until they are golden brown and caramelized. This process takes about 10-15 minutes, but it’s worth the effort to develop those sweet, rich flavors. Once done, layer the caramelized onions over the meatballs in the slow cooker.

4. Make the Gravy: In a bowl, whisk together the beef broth and Worcestershire sauce. Pour this mixture over the meatballs and onions in the slow cooker, ensuring everything is well coated.

5. Cook: Set your slow cooker to low for 6-8 hours or on high for 3-4 hours. During this time, the meatballs will absorb all the wonderful flavors from the broth and onions. Be sure to taste and adjust seasoning with salt and pepper as needed.

6. Garnish and Serve: Before serving, garnish the meatballs with fresh thyme for a pop of color and flavor. Serve them hot, and enjoy the rich, comforting taste of this slow-cooked dish.
