Caramelized Onion Swiss Burgers

The choice of ground beef is critical when crafting a delicious burger. For the juiciest results, aim for an 80/20 fat-to-meat ratio. This means that 80% of the mixture is beef and 20% is fat, which is essential for keeping the burger moist and flavorful during cooking. The fat content not only contributes to juiciness but also helps in achieving that mouthwatering char on the outside of the patty.

Indulge in gourmet excellence with caramelized onion Swiss burgers that are sure to impress! Experience the mouthwatering combination of sweet, rich caramelized onions and creamy Swiss cheese elevating your beef patty to new heights. Perfect for any occasion, these burgers are versatile and can be customized with your favorite toppings and sauces. Whether grilled or pan-seared, each delicious bite promises to be a savory celebration of flavor. Get ready to savor every moment!

Ingredients

1 lb ground beef (80/20 for optimal juiciness)

1 large onion, thinly sliced

2 tablespoons olive oil

1 tablespoon butter

4 slices Swiss cheese

4 burger buns (your choice: brioche, whole wheat, etc.)

1 tablespoon Worcestershire sauce

Salt and pepper, to taste

Optional toppings: arugula, mayonnaise, mustard, pickles

Instructions

Caramelize the Onions:

- In a large skillet, heat the olive oil and butter over medium-low heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for about 20-30 minutes until onions are soft and caramelized. Adjust heat if necessary to avoid burning. Remove from heat and set aside.

Prepare the Patties:

- In a mixing bowl, combine the ground beef, Worcestershire sauce, salt, and pepper. Mix gently until everything is just combined. Divide the mixture into four equal portions and form into patties, making a slight indentation in the center of each to prevent puffing during cooking.

Cook the Burgers:

- Preheat a grill or skillet over medium-high heat. Cook the patties for about 4-5 minutes on one side. Flip the patties, and immediately place a slice of Swiss cheese on top. Cook for an additional 4-5 minutes, or until the cheese is melted and the burger reaches your desired level of doneness. (For medium-rare, aim for an internal temperature of 130°F-135°F.)

Toast the Buns:

- While the burgers are cooking, lightly toast the buns on a separate skillet or on the grill until golden brown.

Assemble the Burgers:

- Place the cooked patty with melted Swiss cheese on the bottom half of each toasted bun. Top generously with caramelized onions and your choice of additional toppings—arugula, mayonnaise, mustard, or pickles.

Finish and Serve:

- Place the top half of the bun onto the burger. Serve hot with your favorite sides like fries or a fresh salad.
