Method
- Step 1: In a mixing bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, parsley, garlic powder, salt, and pepper. Mix until everything is well combined.
- Step 2: Shape the mixture into meatballs, about 1 inch in diameter.
- Step 3: In a large skillet, heat olive oil over medium heat. Add the meatballs and cook until browned on all sides, about 5-7 minutes. Remove the meatballs from the skillet and set them aside.
- Step 4: In the same skillet, add the sliced onions. Cook, stirring frequently, until the onions are caramelized, about 10-15 minutes.
- Step 5: Pour in the beef broth and Worcestershire sauce, stirring to combine. Bring to a simmer.
- Step 6: Return the meatballs to the skillet, cover, and let simmer for an additional 10 minutes.
- Step 7: Preheat the broiler. Sprinkle the shredded Gruyère cheese over the meatballs and onion mixture. Broil for 2-3 minutes, or until the cheese is melted and bubbly.
- Step 8: Remove from the oven and garnish with fresh thyme. Serve hot.
