Ingredients

Scale
  • 1 lb (450g) ground beef
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1 egg
  • 2 cloves garlic, minced
  • 1 tsp onion powder
  • 1 tsp Italian seasoning
  • Salt and pepper, to taste
  • 2 tbsp olive oil
  • 2 large onions, thinly sliced
  • 2 tbsp butter
  • 1 tsp sugar
  • 2 cups beef broth
  • 1/2 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. In a large bowl, combine ground beef, breadcrumbs, Parmesan, egg, garlic, onion powder, Italian seasoning, salt, and pepper. Mix until evenly combined.
  2. Roll into 1-inch meatballs and set aside.
  3. Heat olive oil in a large skillet over medium heat. Brown the meatballs on all sides, about 6–8 minutes. Remove from skillet and set aside.
  4. In the same skillet, melt the butter. Add sliced onions and sprinkle with sugar. Cook over medium-low heat, stirring frequently, until caramelized, about 15–20 minutes.
  5. Sprinkle flour over the onions and stir to coat.
  6. Add beef broth, white wine (if using), and Worcestershire sauce. Scrape the skillet to deglaze and bring to a simmer.
  7. Return meatballs to the skillet. Cover and simmer for 10–15 minutes.
  8. Preheat the broiler. Sprinkle Gruyère cheese over the meatballs and sauce. Broil for 2–3 minutes, or until the cheese is melted and bubbly.
  9. Garnish with parsley (optional) and serve hot with crusty bread, mashed potatoes, or pasta.
