Description
Savory meatballs nestled in a toasted sub roll with caramelized onions and melted cheese, inspired by classic French onion flavors.
Ingredients
Scale
- 1 lb ground beef
- 1/4 cup breadcrumbs
- 1/4 cup grated Parmesan cheese
- 1 large egg
- 2 cloves garlic, minced
- 1 tsp dried oregano
- Salt and pepper to taste
- 2 large onions, thinly sliced
- 2 tbsp butter
- 1 tbsp olive oil
- 4 hoagie rolls or sub buns
- 1 1/2 cups shredded Swiss cheese
- 1 cup beef broth
Instructions
- Preheat oven to 375°F (190°C).
- In a bowl, mix ground beef, breadcrumbs, Parmesan, egg, garlic, oregano, salt, and pepper. Form into 16 meatballs.
- Heat olive oil in a skillet over medium heat. Brown meatballs on all sides; remove and set aside.
- In the same skillet, melt butter and sauté onions over low heat until caramelized, about 20 minutes.
- Return meatballs to 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 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.
- For extra flavor, add a splash of Worcestershire sauce to the meatball mixture.
- Serve with a side of au jus for dipping.
