Description
A savory ground beef mixture flavored with caramelized onions and Swiss cheese, served on buns.
Ingredients
Scale
- 1 tablespoon olive oil
- 1 large yellow onion, thinly sliced
- 1 pound ground beef
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon all-purpose flour
- 1 cup beef broth
- 2 tablespoons Worcestershire sauce
- 1 tablespoon Dijon mustard
- 4 hamburger buns
- 4 slices Swiss cheese
Instructions
- Heat olive oil in a large skillet over medium heat. Add the sliced onion and cook slowly, stirring occasionally, for 20 to 25 minutes until deeply caramelized and brown. Remove onions from the skillet and set aside.
- Add ground beef to the same skillet. Cook over medium-high heat, breaking it up with a spoon, until browned. Drain off any excess fat.
- Stir in salt and pepper. Sprinkle flour over the beef and cook for 1 minute, stirring constantly.
- Pour in beef broth, Worcestershire sauce, and Dijon mustard. Bring the mixture to a simmer. Reduce heat to low, cover, and cook for 10 minutes, stirring occasionally.
- Stir the caramelized onions back into the meat mixture.
- Spoon the meat mixture onto the bottom halves of the hamburger buns. Top each serving with one slice of Swiss cheese.
- Place the open-faced sandwiches on a baking sheet. Broil for 1 to 2 minutes, watching closely, until the cheese is melted and bubbly.
- Place the top halves of the buns on the sandwiches and serve immediately.
Notes
- For deeper onion flavor, cook the onions longer until they are very dark brown.
- You can substitute Gruyère cheese for Swiss cheese.
