Instructions for French Onion Meatballs Recipe
Prepare the Meatballs:
- Preheat the Oven:
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it. - Make the Meatball Mixture:
In a large bowl, combine the ground beef, chopped onion, minced garlic, breadcrumbs, Parmesan cheese, milk, egg, salt, pepper, and thyme. Mix gently until well combined. Be careful not to overmix, which can make meatballs tough. - Form the Meatballs:
Roll the mixture into meatballs about 1 to 1 1/2 inches in diameter. Place them on the prepared baking sheet. - Bake the Meatballs:
Bake the meatballs for 15-20 minutes, or until they are browned and cooked through. Remove from the oven and set aside.
Prepare the French Onion Sauce:
- Caramelize the Onions:
While the meatballs are baking, heat the butter in a large skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for about 10-15 minutes, or until the onions are golden brown and caramelized. Stir in the brown sugar, salt, pepper, and thyme, and cook for another 3-4 minutes. - Deglaze the Pan:
Add the beef broth and white wine to the skillet, scraping up any bits from the bottom of the pan. Let the mixture simmer for 5-7 minutes, or until the sauce has reduced by about half. If you want a thicker sauce, stir in the flour and cook for another 2 minutes until thickened. - Combine the Meatballs and Sauce:
Add the cooked meatballs to the skillet with the onion sauce, stirring gently to coat the meatballs in the sauce. Simmer for another 5-7 minutes, allowing the flavors to meld together.

Add the Cheese and Serve:
- Top with Cheese:
Sprinkle the shredded Gruyère (or Swiss cheese) over the meatballs and onions. Cover the skillet and cook for an additional 2-3 minutes, until the cheese has melted and is bubbly. - Serve:
Garnish with fresh parsley and serve hot. These meatballs are perfect over pasta, mashed potatoes, or with a side of crusty bread to soak up the delicious sauce.
