Ingredients
-
- 1 lb ground beef
-
- 2 large onions, thinly sliced
-
- 2 tablespoons butter
-
- 1 teaspoon sugar
-
- ½ cup beef broth
-
- 2 tablespoons Worcestershire sauce
-
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
-
- Salt and pepper to taste
-
- 4 slices of Gruyère or Swiss cheese
-
- 4 hamburger buns
-
- 1 clove garlic, minced (optional for garlic butter buns)
-
- Additional butter for buns
Instructions
-
- Caramelize the Onions: In a large skillet over medium heat, melt the butter. Add the sliced onions and sugar, cooking and stirring occasionally until the onions are deeply caramelized and sweet, about 20-25 minutes. If the onions start to stick, add a splash of beef broth to deglaze the pan.
-
- Prepare the Burger Patties: In a bowl, season the ground beef with salt, pepper, and Worcestershire sauce. Form into 4 equal-sized patties.
-
- Cook the Patties: In a separate skillet or on a grill, cook the burger patties to your desired level of doneness.
-
- Assemble the Burgers: If desired, prepare garlic butter buns by spreading a mixture of butter and minced garlic on the buns and toasting until golden.
-
- Build the Burgers: On each bun bottom, place a cooked burger patty. Top each patty with a generous helping of caramelized onions and a slice of cheese.
-
- Melt the Cheese: Broil the assembled burgers for a few minutes until the cheese is melted and bubbly.
-
- Garnish and Serve: Sprinkle fresh thyme over the melted cheese, cover with the bun tops, and serve immediately.
