INGREDIENTS
1.5 lbs ground Wagyu beef
1.5 tsp kosher salt
½ tsp black pepper
4 brioche burger buns
6 oz blue cheese (crumbled)
1 large yellow onion (thinly sliced)
2 tbsp butter (plus extra for toasting buns)
2 tbsp olive oil
2 cups arugula
4 slices thick-cut bacon (optional)
INSTRUCTIONS
Caramelize the Onions: Heat 2 tablespoons of butter and 2 tablespoons of olive oil in a skillet over medium heat. Add the sliced onions and a pinch of salt. Cook slowly for 40 to 50 minutes, stirring occasionally until deep golden brown and tender. Set aside.
Cook the Bacon: If using bacon, cook it in a skillet until crispy, then set aside on a paper towel.
Form the Patties: Divide the Wagyu beef into 4 equal portions. Gently shape them into patties about 1 inch thick. Press a small divot in the center of each patty to prevent them from puffing up while cooking. Season both sides generously with salt and pepper.
Sear the Burgers: Heat a cast-iron skillet or grill over high heat. Cook the Wagyu patties for about 3 to 4 minutes without moving or pressing down on them. Flip the patties.
Melt the Cheese: Cook for another 3 to 4 minutes for medium-rare. During the final minute of cooking, top each patty with a generous amount of blue cheese and cover the pan or close the lid to melt the cheese. Remove and let rest for 5 minutes.
Toast the Buns: Butter the cut sides of the brioche buns and toast them in the skillet until golden brown.
Assemble: Place arugula on the bottom bun, add the Wagyu patty with melted blue cheese, top with caramelized onions and crispy bacon, then finish with the top bun.
