Steak and Sandwich Components

Caramelized Onions

Pesto Mayo

Cheese

Method

Caramelized Onions

  1. 1

    Prepare the Onions

    Slice the onion into thin rings.

  2. 2

    Caramelize the Onions

    In a skillet, heat olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, about 20-25 minutes.

Steak Preparation

  1. 3

    Season the Steak

    Pat the skirt steak dry with paper towels. Season both sides generously with salt and black pepper.

  2. 4

    Cook the Steak

    Heat a grill or skillet over high heat. Add the seasoned steak and cook for about 4-5 minutes on each side for medium-rare, or longer if desired. Remove from heat and let rest for 5 minutes.

  3. 5

    Slice the Steak

    After resting, slice the steak against the grain into thin strips.

Pesto Mayo Preparation

  1. 6

    Combine Ingredients

    In a bowl, mix together the mayonnaise and pesto sauce until well combined.

Assembling the Sandwich

  1. 7

    Prepare the Bread

    Slice the baguette or ciabatta bread lengthwise and toast lightly if desired.

  2. 8

    Spread the Pesto Mayo

    Spread a generous amount of pesto mayo on both sides of the bread.

  3. 9

    Layer the Ingredients

    Layer the arugula on the bottom half of the bread, followed by the sliced skirt steak, caramelized onions, and crumbled Gorgonzola cheese.

  4. 10

    Finish the Sandwich

    Place the top half of the bread on the sandwich, press gently, and cut in half to serve.
