Steak

Diane Sauce

Method

Steak Preparation

  1. 1

    Season the Steak

    Pat the filet mignon dry with paper towels. Season both sides generously with salt and black pepper.

  2. 2

    Sear the Steak

    In a large skillet, heat olive oil over medium-high heat. Once hot, add the filet mignon and sear for 3-4 minutes on each side for medium-rare, or until desired doneness. Remove from skillet and let it rest on a plate.

Diane Sauce Preparation

  1. 3

    Sauté Shallots and Garlic

    In the same skillet used for the steak, reduce the heat to medium. Add butter and let it melt. Stir in minced shallots and garlic confit, cooking until shallots are translucent, about 2-3 minutes.

  2. 4

    Add Worcestershire and Broth

    Pour in the Worcestershire sauce and beef broth. Bring the mixture to a simmer, scraping up any browned bits from the bottom of the skillet. Cook for about 5 minutes until the sauce has reduced slightly.

  3. 5

    Finish the Sauce

    Remove the skillet from heat and stir in the chopped parsley and shaved black truffle. Adjust seasoning to taste with salt and pepper.

Assembly and Serving

  1. 6

    Plate the Dish

    Slice the rested filet mignon and place it on a warm plate. Generously spoon the Diane sauce over the steak.

  2. 7

    Garnish

    Garnish with additional shaved black truffle and parsley if desired.

  3. 8

    Serve

    Serve immediately with your choice of sides.
