Sandwich Components

Caramelized Onions

Smoked Jalapeño Aioli

Au Jus

Method

Prepare the Caramelized Onions

  1. 1

    Caramelize the Onions

    Heat olive oil in a skillet over medium heat. Slice the onion and add it to the skillet. Sprinkle with salt and cook, stirring occasionally, until the onions are golden and caramelized, about 15-20 minutes. Remove from heat.

Make the Smoked Jalapeño Aioli

  1. 2

    Blend the Aioli

    In a food processor, combine mayonnaise, smoked jalapeños, garlic, and lemon juice. Blend until smooth. Adjust seasoning to taste.

Prepare the Au Jus

  1. 3

    Simmer the Au Jus

    In a saucepan, combine beef broth and Worcestershire sauce. Bring to a simmer and cook for 10 minutes. Season with black pepper to taste.

Assemble the Sandwich

  1. 4

    Build the Sandwich

    Preheat a grill or skillet. Place sliced prime rib on the bottom half of each brioche bun. Top with caramelized onions and Monterey Jack cheese. Cover with the top half of the bun. Grill or toast until the cheese is melted, about 3-5 minutes.

Serve

  1. 5

    Serve with Au Jus

    Slice the sandwich in half and serve with au jus on the side for dipping.
