Instructions
Prepare the Patty
In a large mixing bowl, combine the ground wagyu beef, finely chopped onions, minced garlic, soy sauce, black pepper, egg, and a pinch of salt. Gently mix the ingredients until just combined. Be careful not to overmix the beef, as this can make the patty dense.
Shape the Patties
Divide the mixture into four equal portions and shape each into a patty about ¾ inch thick. Make a slight indentation in the center of each patty—this ensures even cooking.
Cook the Patties
Heat a grill or skillet over medium-high heat. Cook the patties for 4-5 minutes on each side for medium-rare, or adjust the time to your preferred doneness. During the last minute of cooking, place a slice of Gruyère cheese on each patty and cover to allow the cheese to melt.
Caramelize the Onions
In a skillet, cook sliced onions over medium-low heat with a bit of butter and olive oil. Stir occasionally until the onions become soft, golden, and caramelized. This process should take about 15-20 minutes.
Sauté the Mushrooms
In another skillet, sauté the wild mushrooms with a bit of olive oil until browned and tender. Season with salt and pepper to taste.
Prepare the Truffle Aioli
In a small bowl, mix 1/4 cup of mayonnaise with 1 tsp of truffle oil, a dash of lemon juice, and a pinch of salt. Stir until well combined.
Toast the Brioche Buns
Toast the brioche buns in a skillet or on the grill until golden and slightly crispy.
Assemble the Burger
To build The Royal Umami Burger, spread a generous amount of truffle aioli on the bottom bun. Place the cheesy beef patty on top, followed by caramelized onions, sautéed mushrooms, and a handful of fresh arugula. Add the top bun and serve.
