Ingredients
Scale
- 1 pound ground beef, lean
- 2 large sweet onions, sliced
- 2 cloves garlic, minced
- 1/2 cup beef broth, low-sodium if desired
- 2 tablespoons Worcestershire sauce
- Provolone or mozzarella cheese, to taste
- Sturdy hamburger buns or brioche rolls
Instructions
- In a large skillet over medium heat, add 2 tablespoons of olive oil.
- Once hot, toss in 2 large sliced sweet onions.
- Cook these until they're golden brown and caramelized, about 15-20 minutes, stirring occasionally.
- Once the onions are caramelized, add 2 cloves of minced garlic and 1 pound of ground beef to the skillet.
- Break up the beef using a wooden spoon and cook until browned, about 6-8 minutes.
- Stir in ½ cup of beef broth and 2 tablespoons of Worcestershire sauce.
- Mix well and let it simmer for another 5 minutes until everything is heated through and slightly thickened.
- While the filling simmers, preheat your oven to 350°F (175°C).
- Split open your buns and place them on a baking sheet.
- Spoon generous portions of the savory meat mixture onto each bottom half of the buns.
- Top each one with slices of provolone or mozzarella cheese.
- Pop those into your preheated oven for about 10 minutes or until the cheese is melted and bubbly.
