Recipe Multiplier

  • 1 lb 1 lb Wagyu Ground Beef
  • ¼ lb 1/4 lb Mushrooms sliced
  • 1 ea 1 ea medium Onion sliced
  • 2 tbsp 2 Tbl Garlic Confit Oil
  • 3 oz 3 oz Vermont Sharp Cheddar Cheese
  • 6 tbsp 6 Tbl Garlic Aioli Spread
  • 3 ea 3 ea Brioche Buns
  • Salt & Black Pepper

Instructions

  • Prepare the Garlic Confit Oil ahead of time.
  • Prepare the Garlic Aioli ahead of time.
  • Start your grill to get pre heated.
  • Divide the Wagyu Ground Beef into (3) ⅓ lb patties. Season with Salt & Black Pepper
  • Slice the Onions and Mushrooms
  • Slice the Vermont Sharp Cheddar Cheese

Grilling the Burgers

  • On a cast iron plate for the Kamado Joe or a cast iron pan, add some garlic confit oil to the surface.
  • Once the oil is heated add the onions and mushrooms. Saute them until onions are caramelized and mushrooms are cooked to your liking.
  • Remove them from the cast iron surface.
  • Cook the burgers on the flat cast iron plate. Cooking on the cast iron plate will create a nice crust on the burgers. (You can cook on an open grill grate if you would like.)
  • Flip them after a couple of minutes.
  • Add the Vermont Sharp Cheddar Cheese
  • Continue to cook to your temperature you like.
    I would recommend medium rare @ 130° for a Wagyu burger.
    Pull at 120-125° to keep from overcooking. The temperature will rise as it rests.
  • Toast the Brioche Buns over the fire.
  • Assemble the burgers with Garlic Aioli, Tomato, Pickles, the caramelized Onions and Mushrooms and top with the Wagyu Cheeseburger.
  • Enjoy!
