Burger Ingredients

Cabernet Caramelized Onions

Pimentón Horseradish Rémoulade

Sides (Optional)

Method

Burger Preparation

  1. 1

    Prepare the Wagyu Beef Patties

    In a mixing bowl, form the ground Wagyu beef into two equal-sized patties. Season both sides with salt and pepper to taste.

  2. 2

    Cook the Prosciutto

    In a skillet over medium heat, cook the prosciutto until crispy, about 3-4 minutes. Remove from skillet and place on paper towels to drain excess grease.

  3. 3

    Cook the Patties

    In the same skillet, add the Wagyu beef patties and cook for about 4-5 minutes per side for medium-rare, or until desired doneness. Add a slice of sharp white cheddar on top of each patty in the last minute of cooking to melt.

  4. 4

    Toast the Brioche Buns

    While the burgers are cooking, lightly toast the brioche buns in the skillet for about 1-2 minutes until golden brown.

Caramelized Onions

  1. 5

    Cook the Onions

    In a separate pan, heat olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for 15-20 minutes, stirring occasionally, until onions are soft and golden.

  2. 6

    Add Cabernet Wine

    Pour in the Cabernet Sauvignon wine and let it simmer until the liquid reduces by half and becomes syrupy, about 10-15 minutes.

Rémoulade Preparation

  1. 7

    Mix the Rémoulade

    In a small bowl, combine mayonnaise, prepared horseradish, pimentón, and lemon juice. Mix well and set aside.

Assemble the Burger

  1. 8

    Build the Burger

    On the bottom half of each toasted brioche bun, spread a generous amount of the pimentón horseradish rémoulade. Place the cooked Wagyu beef patty with melted cheddar on top, followed by crispy prosciutto, a slice of tomato, and a handful of arugula. Top with the other half of the brioche bun.

Serve

  1. 9

    Choose Your Side

    Serve the Wagyu beef & prosciutto burger with your choice of hand-cut fries, Napa slaw, or a small house salad.
