Method

Steak Preparation

  1. 1

    Prepare the Steak

    Remove the flat iron steaks from the refrigerator and allow them to come to room temperature for about 30 minutes.

  2. 2

    Season the Steaks

    Rub the steaks with olive oil and season both sides generously with salt and black pepper.

  3. 3

    Heat the Grill/Skillet

    Preheat your grill or skillet over medium-high heat until hot.

  4. 4

    Cook the Steaks

    Cook the steaks for 5-7 minutes on each side for medium-rare, or until they reach your desired doneness.

  5. 5

    Rest the Steaks

    Remove from heat and let the steaks rest for 5 minutes before slicing.

Fries Preparation

  1. 6

    Prepare the Potatoes

    Peel the russet potatoes and cut them into thin strips (about 1/4 inch thick) for fries.

  2. 7

    Rinse and Dry

    Rinse the cut potatoes under cold water to remove excess starch, then pat them dry with a kitchen towel.

  3. 8

    Heat the Oil

    In a large pot or deep fryer, heat the vegetable oil to 350°F (175°C).

  4. 9

    Fry the Potatoes

    Carefully add the potato strips in batches to avoid overcrowding. Fry until golden brown and crispy, about 4-5 minutes.

  5. 10

    Drain and Season

    Remove fries with a slotted spoon and drain on paper towels. Season with salt to taste while still hot.

Bearnaise Sauce Preparation

  1. 11

    Prepare the Shallots

    In a small saucepan, combine shallots, white wine vinegar, and chopped tarragon. Heat over medium heat until the shallots are soft and the liquid has reduced by half.

  2. 12

    Strain the Mixture

    Remove from heat and let cool slightly. Strain the mixture, retaining the liquid and discarding the shallots.

  3. 13

    Combine Egg Yolks and Liquid

    In a medium bowl, whisk together the egg yolks and the strained liquid until combined.

  4. 14

    Thicken the Mixture

    Place the bowl over a pot of simmering water (double boiler) and whisk continuously until thickened.

  5. 15

    Add the Butter

    Slowly drizzle in the melted unsalted butter while continuing to whisk until the sauce is creamy and thick.

  6. 16

    Finish the Sauce

    Stir in the lemon juice, and season with salt and black pepper to taste.
