Bordelaise Butter

Smashed Duck Fat Potatoes

Sauce Verte

Method

Cooking the Steak

  1. 1

    Prepare the Steak

    Preheat the grill to high heat. Rub the flat iron steak with olive oil, then season generously with salt, black pepper, and smoked paprika.

  2. 2

    Grill the Steak

    Grill the steak for about 4-5 minutes on each side for medium-rare, or until the desired doneness is achieved.

  3. 3

    Rest the Steak

    Remove the steak from the grill and let it rest for 5 minutes before slicing.

Making Bordelaise Butter

  1. 4

    Prepare the Sauce

    In a saucepan, combine red wine and shallots. Bring to a simmer and reduce until almost dry. Add veal demi-glace and thyme, and simmer for another 5 minutes.

  2. 5

    Finish the Butter

    Remove from heat and whisk in the unsalted butter until melted and well combined. Set aside.

Preparing Smashed Duck Fat Potatoes

  1. 6

    Cook the Potatoes

    Boil the Yukon Gold potatoes until fork-tender, about 15-20 minutes. Drain and let cool slightly.

  2. 7

    Smashed Potatoes

    Smash the potatoes gently with a fork, then drizzle with duck fat. Season with salt, pepper, and sprinkle chopped chives on top.

Making Sauce Verte

  1. 8

    Blend the Sauce

    In a food processor, combine parsley, basil, capers, garlic, and olive oil. Blend until smooth.

  2. 9

    Finish Sauce Verte

    Adjust seasoning with salt and pepper to taste. Set aside until ready to serve.
