Ingredients

Scale

Meatballs

  • 1 lb (450 g) ground beef

  • ½ cup breadcrumbs

  • ¼ cup grated Parmesan cheese

  • 1 egg

  • 2 cloves garlic, minced

  • 1 tsp onion powder

  • 1 tsp Italian seasoning

  • Salt and pepper, to taste

Sauce & Finishing

  • 2 tbsp olive oil

  • 2 large onions, thinly sliced

  • 2 tbsp butter

  • 1 tsp sugar

  • 2 cups beef broth

  • ½ cup dry white wine (optional)

  • 1 tbsp Worcestershire sauce

  • 1 tbsp all-purpose flour

  • 1 cup shredded Gruyère or Swiss cheese

  • Fresh parsley for garnish (optional)

Instructions

1. Prepare the Meatballs

  • In a large bowl, combine ground beef, breadcrumbs, Parmesan, egg, garlic, onion powder, Italian seasoning, salt, and pepper.

  • Mix until evenly combined.

  • Roll into 1-inch meatballs and set aside.

2. Cook the Meatballs

  • Heat olive oil in a large skillet over medium heat.

  • Brown meatballs on all sides, about 6–8 minutes.

  • Remove from skillet and set aside.

3. Make the French Onion Sauce

  • In the same skillet, melt butter.

  • Add sliced onions and sprinkle with sugar.

  • Cook over medium-low heat, stirring frequently, until caramelized, about 15–20 minutes.

  • Sprinkle flour over onions and stir to coat.

  • Add beef broth, white wine (if using), and Worcestershire sauce. Scrape the skillet to deglaze and bring to a simmer.

4. Combine and Simmer

  • Return meatballs to the skillet.

  • Cover and simmer for 10–15 minutes until meatballs are fully cooked and flavors meld.

5. Add the Cheese

  • Preheat the broiler.

  • Sprinkle Gruyère cheese over meatballs and sauce.

  • Broil for 2–3 minutes, or until cheese is melted and bubbly.

6. Serve

  • Garnish with fresh parsley if desired.

  • Serve hot with crusty bread, mashed potatoes, or pasta.

Notes

  • Caramelization: Cook onions low and slow to get deep, rich flavor.

  • Wine: White wine adds depth but can be omitted if preferred.

  • Make Ahead: Meatballs can be browned ahead of time and stored in the fridge for up to 24 hours before simmering in the sauce.
