Ingredients and Preparation
To make these burgers, gather the following:
- 1 lb ground beef (80/20 ratio for juiciness)
- 2 large onions, thinly sliced
- 2 tablespoons butter
- 1 teaspoon sugar
- 1/2 cup beef broth
- 2 tablespoons Worcestershire sauce
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
- Salt and pepper, to taste
- 4 slices of Gruyère cheese (or Swiss cheese as an alternative)
- 4 hamburger buns
- 1 clove garlic, minced (optional for garlic butter buns)
- Additional butter for buns
Step-by-Step Preparation
- Caramelizing the Onions:
- In a skillet over medium heat, melt butter and add sliced onions.
- Sprinkle with sugar and a pinch of salt. Cook, stirring occasionally, for 20–25 minutes until soft and golden brown.
- Stir in beef broth, Worcestershire sauce, and thyme. Let the liquid reduce. Set aside.
- Shaping the Beef Patties:

Cooking Techniques
Cooking the Burger Patties
- Heat a grill or skillet over medium-high heat.
- Cook the patties for 3–4 minutes per side or until your desired level of doneness is reached.
Toasting the Buns and Adding the Cheese
- Spread softened butter (or garlic butter) on the cut sides of the hamburger buns. Toast in a skillet until golden brown.
- Place a slice of Gruyère cheese on each patty during the last minute of cooking, covering the skillet to melt the cheese.
Adding Complementary Ingredients
Layer the toasted bun bottoms with:
- A generous portion of caramelized onions.
- The cheesy beef patty.
- Optional extras like arugula, Dijon mustard, or crispy bacon for added flavor.
Customizing the Recipe
- Vegetarian Option: Use plant-based patties and substitute vegetable broth for beef broth.
- Cheese Alternatives: Swap Gruyère with Swiss, provolone, or even a sharp cheddar.
- Spicy Variation: Add a slice of jalapeño or a smear of spicy aioli.
Serving Suggestions

- Crispy French fries or sweet potato fries.
