Ingredients
Scale
Meat:
- 1 pound (453 grams) ground beef
Onions and Seasonings:
- 2 large onions, thinly sliced
- 1 teaspoon sugar
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper to taste
Cooking Liquids and Sauces:
- 2 tablespoons butter
- 1/2 cup beef broth
- 2 tablespoons Worcestershire sauce
Cheese and Buns:
- 4 slices of Gruyere or Swiss cheese
- 4 hamburger buns
- 1 clove garlic, minced (optional for garlic butter buns)
- Additional butter for buns
Instructions
- Transform yellow onions into a luscious caramel-like topping by simmering in butter over medium heat for 20-25 minutes, stirring periodically until they develop a rich, golden-brown color and sweet essence.
- Create burger patties by gently mixing ground beef with Worcestershire sauce, salt, and pepper, carefully forming four uniform discs without overworking the meat.
- Preheat grill or skillet to medium-high heat and cook patties 4-5 minutes per side, achieving desired internal temperature while developing a robust exterior crust.
- Enhance burger buns by brushing with garlic-infused butter and toasting until achieving a crisp, golden-brown surface.
- Layer each toasted bun base with a perfectly cooked burger patty, generously draping with the deeply caramelized onion mixture.
- Crown each burger with a slice of cheese, then slide under the broiler for 2-3 minutes until the cheese melts into a luxurious, bubbling blanket.
- Garnish with fresh thyme leaves, crown with bun tops, and serve immediately while flavors remain vibrant and textures are at peak deliciousness.
Notes
- Slow-cook onions patiently to develop rich, deep caramelized flavor without burning them by maintaining medium-low heat and stirring occasionally.
- Choose high-fat ground beef like 80/20 chuck for juicier, more flavorful burger patties that won’t dry out during cooking.
- Swap regular buns with gluten-free alternatives or use lettuce wraps to make the recipe suitable for gluten-sensitive diners.
- Balance the intense sweetness of caramelized onions by adding a small splash of balsamic vinegar during the last few minutes of cooking for complexity.
