Ingredients

  • 3 Brioche buns
  • 1 pound ground Wagyu beef
  • salt
  • fresh ground black pepper
  • 4 tablespoons butter divided
  • 3 slices Aged White Cheddar

Red Wine Caramelized Onions

  • 1 large sweet onion
  • ½ tablespoon butter
  • ½ tablespoon cooking oil
  • 2 tablespoons red wine
  • Salt

Roasted Garlic Aioli

  • 4 cloves garlic
  • cup Mayo

Instructions

Wagyu Beef Burger

  • Spread butter onto the inside of the top and bottom bun slice and lightly toast, butter side down, in 12" skillet on medium heat until the cut side of the bun develops a crispy, toasted, exterior. Turn off the heat once done.
  • Divide 1 lb of beef into three equal sections and form into round patties, being careful not to over work the meat, yet pressing firmly enough for the meat to hold together. Press an indentation into the center of each patty to prevent it from puffing excessively during cooking.
  • Season each side of the patty liberally with salt and pepper.
  • Add enough butter to coat the bottom of a cast-iron skillet heated to medium high and gently place in the patties once it has melted. Work in batches if necessary.
  • Once in the pan, do not move the patties, or press/squish the meat. Moving the patties unnecessarily will prevent a good sear from forming and pressing the meat is a deadly sin that causes delicious juices to escape.
  • After ~2 minutes of cooking, flip each patty and add a slice of cheese to the top of the patty while the burger finishes cooking.
  • Remove from the skillet while burgers are rare, or medium rare (~125 degrees). Overcooking Wagyu beef will cook out all of the flavorful goodness that makes Wagyu a premium product.
  • Place patty on toasted bun slathered with roasted garlic aioli, and topped with caramelized onions.

Red Wine Caramelized Onions (Prepare in advance)

  • Slice ends off of onions, cut in half and then cut into ⅛" strips.
  • Add butter and oil into saute pan and heat to medium low.
  • Add onions and salt to taste.
  • Cook 45 minutes, stirring occasionally to prevent scorching, until onions are brown and sticky. Don't raise the heat to rush the process or the flavors won't develop.
  • When onions are caramelized deglaze the pan with red wine and stir liquid into onions.
  • Remove onions from pan and set aside, keeping warm.

Roasted Garlic Aioli (Prepare while onions caramelize)

  • Roast garlic cloves in oven pre-heated to 375 for 30 minutes, or until cloves are soft to the touch. Check regularly to ensure they do not overcook.
  • Smash the cloves into a paste and mince with knife to ensure they are fully separated.
  • Mix with mayo and set aside.

Notes

Overworking the meat can cause patties to get tough.
If you don't have Wagyu beef, you can still use this recipe to make a killer burger. However, this recipe was specifically designed to compliment the subtle sweetness and tender, buttery flavor of premium Wagyu beef.
