Ingredients
- 1 lb ground beef
- 1 egg
- 1/2 cup breadcrumbs
- 1/4 cup grated onion
- 2 cloves garlic, minced
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tbsp Worcestershire sauce
- 1 tsp dried oregano
- 3 large yellow onions, thinly sliced
- 2 tbsp olive oil or butter
- 2 cloves garlic, minced
- 2 cups beef broth
- 1 tbsp Worcestershire sauce
- 1 tsp fresh thyme (or 1/2 tsp dried)
- Salt and pepper to taste
- 4 sub rolls or hoagie buns
- 8 slices Gruyère, provolone, or mozzarella cheese
- Optional: fresh parsley for garnish
Instructions
- Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
- In a large bowl, mix ground beef, egg, breadcrumbs, grated onion, garlic, salt, pepper, Worcestershire sauce, and oregano.
- Roll the mixture into meatballs and place on the baking sheet. Bake for 18–20 minutes until browned and cooked through.
- Meanwhile, heat oil or butter in a skillet over medium-low heat. Add sliced onions and cook for 25 minutes, stirring often, until deeply golden and caramelized.
- Add garlic and thyme to the onions, cooking for another minute.
- Deglaze the pan with Worcestershire sauce and beef broth. Simmer for 5–7 minutes to reduce slightly.
- Add cooked meatballs to the skillet and simmer in the onion broth for a few minutes to absorb the flavor.
- Toast the sub rolls lightly. Fill with meatballs and onions, top with cheese slices.
- Broil for 1–2 minutes until cheese is melted and bubbly.
- Garnish with fresh parsley if desired, and serve hot.
Notes
- Add a splash of red wine to the broth for extra richness.
- Ground turkey can be used for a lighter option.
- Swiss or white cheddar work well as cheese alternatives.
- Brush rolls with garlic butter before toasting for added flavor.
- Leftovers reheat well on the stovetop; toast bread fresh to avoid sogginess.
