Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Meatballs:
1 lb 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
For the Sauce and Finishing:
2 tbsp olive oil
2 large onions, thinly sliced
2 tbsp butter
1 tsp sugar
2 cups beef broth
1 tbsp Worcestershire sauce
1 tbsp all-purpose flour
1 cup shredded Gruyère or Swiss cheese
Fresh parsley for garnish (optional)
Directions
Prepare the Meatballs:
In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, minced garlic, onion powder, Italian seasoning, salt, and pepper. Mix until evenly combined.
Shape and Brown:
Roll the meat mixture into 1‑inch meatballs. Heat the olive oil in a large skillet over medium heat and brown the meatballs on all sides (about 6–8 minutes). Remove them from the skillet and set aside.
Caramelize Onions:
In the same skillet, melt the butter. Add the sliced onions and sprinkle with sugar. Cook over medium‑low heat, stirring frequently, until the onions are soft and golden (about 15–20 minutes).
Thicken and Build Sauce:
Sprinkle the flour over the onions and stir to coat. Add the beef broth and Worcestershire sauce, scraping up any browned bits from the bottom of the skillet. Bring to a simmer and let the sauce thicken slightly.
Simmer Meatballs:
Return the browned meatballs to the skillet, nestling them into the sauce. Cover and simmer for 10–15 minutes so the meatballs finish cooking and absorb the flavors.
Add Cheese:
Preheat your broiler. Sprinkle the shredded Gruyère (or Swiss) over the meatballs and sauce. Broil for 2–3 minutes, until the cheese is melted and bubbly.
Serve:
Garnish with fresh parsley if desired and serve hot over your choice of sides.
