Steak

Caramelized Onions

Black Truffle Mayo

Sandwich Assembly

Method

Prepare the Steak

  1. 1

    Slow Cook the Steak

    Season the steak with salt and black pepper. Heat olive oil in a skillet over medium-high heat. Sear the steak on both sides until browned, about 3-4 minutes per side. Transfer to a slow cooker and cook on low for 6-8 hours until tender. Shred or slice the steak for the sandwich.

Caramelize the Onions

  1. 2

    Caramelize the Onions

    In a skillet, melt butter over medium heat. Add sliced onions and sugar. Cook slowly, stirring frequently, until the onions are deep golden brown and caramelized, about 20-25 minutes.

Make the Black Truffle Mayo

  1. 3

    Combine Ingredients

    In a small bowl, mix mayonnaise with black truffle oil until well combined. Set aside.

Cook the Eggs

  1. 4

    Fry the Eggs

    In a non-stick skillet, fry the eggs to your desired doneness (sunny-side up, over-easy, etc.).

Assemble the Sandwich

  1. 5

    Build the Sandwich

    Split the brioche buns in half and toast lightly. Spread black truffle mayo on the bottom half of each bun. Layer with arugula, shredded steak, caramelized onions, a slice of cheddar cheese, and the fried egg. Top with the other half of the bun and serve immediately.
