Ingredients
  

For the Patty:

  • 1 500g Ground wagyu beef (80/20 lean-to-fat ratio) Wagyu beef ensures an incredibly rich and buttery flavor, with high-fat content that adds incredible juiciness to the patty. It’s the foundation of a decadent gourmet burger.
  • 1 Small onion, finely chopped Onions provide subtle sweetness, balancing the rich beef.
  • 2 Garlic cloves, minced Garlic adds a bold, savory undertone that blends beautifully with the beef and truffle flavors.
  • 1 tbsp Black truffle oil Truffle oil enhances the patty with that earthy, luxurious flavor that defines this burger.
  • 1 tbsp Dijon mustard Dijon mustard adds a slight tang that contrasts beautifully with the richness of the wagyu beef.
  • 1 Salt and freshly ground black pepper to taste Season generously to bring out the best in the wagyu and enhance the overall flavor.

For the Toppings:

  • 4 Slices of aged Gruyère cheese Aged Gruyère adds a nutty, complex flavor that complements the rich beef.
  • 1 Sautéed mushrooms (button mushrooms or wild mushrooms) Mushrooms add an earthy element that works perfectly with the truffle flavor.
  • 1 Caramelized onions Sweet, caramelized onions add depth and balance to the savory components of the burger.
  • 1 Fresh arugula leaves Arugula adds a peppery freshness to cut through the richness.
  • 1 Truffle aioli (homemade or store-bought) This creamy aioli takes the truffle flavor up a notch, making every bite luxurious.

For the Buns:

  • 4 Brioche buns (toasted) Brioche buns are soft, slightly sweet, and perfect for soaking up all the flavors without falling apart.

Instructions
 

Prepare the Patty Mix:

  • In a large mixing bowl, combine the ground wagyu beef, finely chopped onion, minced garlic, truffle oil, Dijon mustard, egg, salt, and pepper. Use your hands to gently mix the ingredients, being careful not to overwork the meat as that can result in a tough patty. The aim here is to combine everything just enough so the flavors meld while keeping the meat tender.

Shape the Patties:

  • Divide the beef mixture into four equal portions. Gently shape each portion into a patty that is about ¾ inch thick. Make a slight indentation in the center of each patty to ensure even cooking. This will help the patty cook flat and prevent it from puffing up in the middle.

Cook the Patties:

  • Heat a grill or skillet over medium-high heat. Cook the patties for 4-5 minutes on each side for a medium-rare finish. If you prefer the burgers to be cooked more, adjust the cooking time accordingly. During the last minute of cooking, place a slice of Gruyère cheese on top of each patty, covering the grill or skillet briefly to allow the cheese to melt.

Sauté the Mushrooms:

  • While the patties cook, heat a small pan over medium heat. Add a bit of olive oil and sauté the mushrooms until they are golden brown and soft. Season with a pinch of salt and set aside.

Caramelize the Onions:

  • In another pan, add a tablespoon of butter and cook the sliced onions over medium-low heat. Stir frequently until the onions become soft and golden brown, about 10-15 minutes. Set aside.

Toast the Buns:

  • While the patties are finishing, lightly toast the brioche buns on the grill or in a skillet until golden brown and slightly crisp on the outside.

Assemble the Burger:

  • To build your Truffle Royale Burger, start by spreading a generous layer of truffle aioli on the bottom half of each bun. Place the cheesy patty on top, followed by sautéed mushrooms, caramelized onions, and a handful of fresh arugula. Top with the toasted brioche bun and serve immediately.
