Ingredients:
- 1 lb ground beef
- 1 lb ground pork
- 1 cup breadcrumbs
- 2 eggs
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 1/2 cup beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon thyme
- 1 cup grated Gruyère cheese
- Salt and pepper to taste
- 2 tablespoons olive oil for frying
Directions:
- In a skillet, melt butter over medium heat and add sliced onions with a pinch of salt. Cook, stirring occasionally, until onions are caramelized, about 15-20 minutes. Set aside to cool.
- In a large bowl, combine ground beef, ground pork, breadcrumbs, eggs, salt, pepper, thyme, half of the caramelized onions, and Worcestershire sauce. Mix until well combined.
- Shape the mixture into 1.5-inch meatballs.
- In the same skillet, heat olive oil over medium heat. Add meatballs and fry until browned on all sides and cooked through, about 10-12 minutes.
- Add beef broth to the skillet and bring to a simmer. Return the remaining caramelized onions to the skillet and cook for an additional 5 minutes.
- Sprinkle Gruyère cheese over the meatballs and onions. Cover the skillet briefly to melt the cheese.
- Serve hot, garnished with a little more thyme if desired.
