Ingredients
Scale
Meat:
- 1.5 pounds (680 grams) ground beef (80/20 recommended)
Cheese and Bread:
- 4 slices Gruyere cheese (or Swiss)
- 4 burger buns, toasted
Caramelizing Ingredients:
- 2 tablespoons unsalted butter
- 2 large yellow onions, thinly sliced
- 0.5 teaspoon salt
- 0.5 teaspoon sugar
- 1 teaspoon fresh thyme (or 0.5 teaspoon dried)
- 1 tablespoon balsamic vinegar (optional, for depth)
Seasoning and Spread:
- Salt, to taste
- Black pepper, to taste
- 0.25 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 teaspoon lemon juice
Instructions
- Gently melt butter in a spacious skillet over medium temperature, creating a silky base for transforming raw onions into a rich, caramelized delicacy.
- Introduce sliced onions to the buttery landscape, sprinkling salt, sugar, and fragrant thyme to enhance their natural sweetness and develop deep golden complexity.
- Tenderly stir the onions every few minutes, allowing them to slowly transform and develop a luxurious amber color over 25-30 minutes of patient cooking.
- During the final moments of caramelization, drizzle balsamic vinegar to introduce a subtle tangy undertone, then set the onions aside to cool slightly.
- Whisk mayonnaise, Dijon mustard, and fresh lemon juice in a compact bowl, creating a vibrant, creamy spread with bright, zesty notes.
- Refrigerate the spread to allow flavors to meld and maintain its cool, smooth consistency until burger assembly.
- Gently form ground beef into four uniform patties, ensuring even thickness for consistent cooking.
- Season each patty generously with salt and pepper, creating a simple yet flavorful exterior.
- Heat a skillet or grill pan until dangerously hot, then carefully place patties to develop a robust, caramelized crust.
- Cook patties for 3-4 minutes per side, achieving a perfect medium doneness with a hint of pink in the center.
- During the final minute of cooking, crown each burger with a slice of melting cheese, allowing it to become gloriously smooth and cascading.
- Transfer the cheese-draped burgers to waiting buns, topped with the golden caramelized onions and dollop of prepared spread.
Notes
- Master caramelization by using a wide skillet and stirring onions consistently to prevent burning while developing deep, rich flavor.
- Control onion sweetness by adjusting sugar quantity, allowing natural sugars to enhance the caramelization process without overwhelming the dish.
- Experiment with different cheese varieties like Gruyère or aged cheddar to elevate the burger’s complexity and create unique flavor profiles.
- Achieve perfect burger doneness by using a meat thermometer, ensuring internal temperature reaches 160°F for food safety while maintaining juicy texture.
