Burger Patty

Toppings

Bun

French Fries

Method

Prepare the Burger Patty

  1. 1

    Form the Patty

    In a large bowl, combine the Wagyu beef, salt, and black pepper. Mix gently to avoid overworking the meat. Form the mixture into two equal patties, making a slight indentation in the center of each.

  2. 2

    Cook the Patty

    Preheat a grill or skillet over medium-high heat. Cook the patties for about 4-5 minutes on each side for medium-rare, adding the aged cheddar cheese on top during the last minute of cooking to melt.

Prepare the Toppings

  1. 3

    Cook the Bacon

    In a skillet over medium heat, cook the Old Major pepper bacon until crispy, about 5-7 minutes. Place on a paper towel to drain excess grease.

  2. 4

    Prepare Onion Jam

    If using store-bought onion jam, skip this step. Otherwise, cook sliced onions in a pan with a bit of oil over low heat, stirring occasionally until caramelized (about 20 minutes).

Assemble the Burger

  1. 5

    Toast the Buns

    Lightly butter the brioche buns and toast them on the grill or in a skillet until golden brown.

  2. 6

    Build the Burger

    On the bottom half of each toasted brioche bun, layer the Wagyu patty with melted cheddar, crispy bacon, a generous spoonful of onion jam, and a few bread & butter pickles. Top with the other half of the bun.

Prepare the French Fries

  1. 7

    Cut the Potatoes

    Wash and cut the Russet potatoes into thin strips for frying.

  2. 8

    Fry the Potatoes

    Heat oil in a deep fryer or a large pot to about 350°F (175°C). Carefully add the potato strips in batches and fry until golden brown, about 4-5 minutes. Remove from the oil and drain on paper towels. Season with salt to taste.
