Burger Ingredients

Method

Burger Preparation

  1. 1

    Caramelize the Onions

    In a skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions are caramelized and golden brown, about 15-20 minutes. Remove from heat and set aside.

  2. 2

    Cook the Mushrooms

    In the same skillet, add another tablespoon of olive oil and the sliced mushrooms. Season with salt and black pepper. Sauté over medium heat until the mushrooms are browned and softened, about 5-7 minutes. Remove from heat and set aside.

  3. 3

    Grill the Wagyu Patties

    Preheat a grill or grill pan over medium-high heat. Season the Wagyu beef patties with salt and black pepper. Grill the patties for about 4-5 minutes on each side for medium-rare, or until desired doneness. In the last minute of cooking, place a slice of Taleggio cheese on each patty to melt.

  4. 4

    Toast the Buns

    While the patties are grilling, cut the burger buns in half and lightly toast them on the grill or in a toaster.

  5. 5

    Assemble the Burgers

    On the bottom half of each toasted bun, place a lettuce leaf, followed by the grilled Wagyu patty with melted Taleggio, caramelized onions, and sautéed mushrooms. Add sliced tomatoes and cover with the top half of the bun.

  6. 6

    Serve

    Serve the Wagyu burgers immediately with your favorite side dishes.
