Description
Savory beef meatballs simmered with caramelized onions and beef broth, topped with melted Swiss cheese, and served in toasted sub rolls for a flavorful French onion-inspired sandwich.
Ingredients
- 1 lb ground beef
- ¼ cup breadcrumbs
- ¼ cup grated Parmesan cheese
- 1 large egg
- 2 cloves garlic, minced
- 1 teaspoon dried oregano
- Salt and pepper, to taste
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 4 hoagie rolls or sub buns
- 1 ½ cups shredded Swiss cheese
- 1 cup beef broth
Instructions
- Preheat oven to 375°F (190°C).
- In a large bowl, combine ground beef, breadcrumbs, Parmesan, egg, garlic, oregano, salt, and pepper. Mix well and form into 16 meatballs.
- Heat olive oil in a skillet over medium heat. Brown meatballs on all sides, then remove and set aside.
- In the same skillet, melt butter and sauté sliced onions over low heat until caramelized, about 20 minutes.
- Return meatballs to the skillet, add beef broth, and simmer for 10 minutes until meatballs are cooked through and broth is slightly reduced.
- Slice sub rolls lengthwise, leaving a hinge. Place 4 meatballs per roll, spoon caramelized onions and some broth over them.
- Top each sub with shredded Swiss cheese.
- Place subs on a baking sheet and bake for 10 minutes or until cheese is melted and bubbly.
- Serve hot.
Notes
- Use low-sodium beef broth to control saltiness.
- Add a splash of Worcestershire sauce to the meatball mixture for extra depth.
- Substitute ground turkey or chicken for a lighter meatball.
- Serve with a side of au jus or extra beef broth for dipping.
- Add sautéed mushrooms or bell peppers for more vegetable flavor.
