Caramelized onions, sautéed mushrooms, gruyere cheese, horseradish sauce, au jus.

In a bowl, mix the ground beef with salt and black pepper. Divide into 4 equal portions and form into patties.

Form the Patties

Grill or pan-fry the patties over medium-high heat for about 4-5 minutes on each side, or until they reach your desired doneness.

Cook the Patties

In a skillet, heat 1 tablespoon of olive oil over medium heat. Add sliced onions and cook slowly for about 15-20 minutes, stirring occasionally, until they are golden brown and caramelized.

Caramelize the Onions

In the same skillet, add 1 tablespoon of butter and the sliced mushrooms. Sauté for about 5-7 minutes until the mushrooms are tender and browned.

Sauté the Mushrooms

In a small bowl, combine the horseradish sauce and mayonnaise. Adjust seasoning to taste.

Mix the Sauce

In a small saucepan, combine beef broth and Worcestershire sauce. Heat over medium heat until warmed through.

Prepare the Au Jus

Place each patty on a burger bun, top with caramelized onions, sautéed mushrooms, and a slice of Gruyere cheese. Serve with horseradish sauce and au jus on the side for dipping.
