Ingredients
  

Meatballs

  • 1 lb ground beef
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1 large egg
  • 2 cloves garlic minced
  • 1 tsp dried thyme
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 2 tbsp olive oil for frying

Onion Sauce

  • 4 large onions thinly sliced
  • 2 tbsp unsalted butter
  • 2 tbsp olive oil
  • 1 tsp sugar
  • 1/2 cup beef broth
  • 1/4 cup dry white wine optional
  • 1 tsp dried thyme
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 1 cup shredded Gruyère or Swiss cheese
  • Fresh parsley chopped (for garnish)

Instructions
 

  • Prepare the Meatballs: In a large bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, egg, minced garlic, dried thyme, salt, and black pepper. Mix until well combined. Form the mixture into small meatballs, about 1 inch in diameter.
  • Cook the Meatballs: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the meatballs and cook until browned on all sides and cooked through, about 8-10 minutes. Remove the meatballs from the skillet and set aside.
  • Caramelize the Onions: In the same skillet, add the unsalted butter and 2 tablespoons of olive oil. Add the sliced onions and cook over medium-low heat, stirring occasionally, until the onions are golden brown and caramelized, about 25-30 minutes. Add the sugar halfway through the cooking process to help with caramelization.
  • Make the Sauce: Add the beef broth, dry white wine (if using), dried thyme, salt, and black pepper to the caramelized onions. Stir to combine and bring to a simmer. Cook for an additional 5 minutes to allow the flavors to meld.
  • Combine Meatballs and Sauce: Return the meatballs to the skillet with the onion sauce. Stir gently to coat the meatballs in the sauce. Sprinkle the shredded Gruyère or Swiss cheese over the top.
  • Bake: Preheat your oven to 375°F (190°C). Transfer the skillet to the preheated oven and bake for 10 minutes, or until the cheese is melted and bubbly.
  • Serve and Garnish: Remove the skillet from the oven and garnish with chopped fresh parsley. Serve hot.

Notes

And there you have it! Your French Onion Meatballs are ready.
This dish pairs wonderfully with mashed potatoes, rice, or a fresh green salad. Enjoy the rich flavors and the comforting combination of caramelized onions, tender meatballs, and melted cheese.
 
A few tips from my kitchen to yours:
  • For an extra depth of flavor, use a mix of beef and pork for the meatballs.
  • If you don’t have Gruyère, Swiss cheese or mozzarella also works well.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated gently.
