Recipe Steps

You Will Need

  • Olive Oil
  • Salt
  • Pepper
  • Cooking Spray
  • 1 Baking Sheet
  • 1 Medium Non-Stick Pan

Before You Cook

  • 1

    Start the Potatoes

    Halve fingerling potatoes lengthwise. Toss potatoes on prepared baking sheet with 2 tsp. olive oil, ½ tsp. salt, and a pinch of pepper. Spread into a single layer and bake 20 minutes. Potatoes will finish cooking in a later step. While potatoes bake, prepare ingredients.

  • 2

    Prepare the Ingredients

    Mince garlic. Peel and slice shallot into ¼" rounds. Mince parsley stems and leaves. Rinse peas under warm water if still frozen. Rinse steaks, pat dry, and season both sides with ¼ tsp. salt and a pinch of pepper.

  • 3

    Sear the Steaks

    Heat 2 tsp. olive oil in a medium non-stick pan over medium-high heat. Place steaks in hot pan and cook until steaks are browned and reach a minimum internal temperature of 145 degrees, 4-5 minutes per side. Remove steaks to a plate and tent with foil. Rest at least 5 minutes. Reserve pan; no need to wipe clean. While steaks rest, finish potatoes.

  • 4

    Finish the Potatoes

    After potatoes have baked 20 minutes, add peas, garlic, and shallots to baking sheet and toss. Bake until potatoes are golden brown and tender, 6-8 minutes. Remove from oven and garnish potatoes with parsley. While potatoes bake, make sauce.

  • 5

    Make the Sauce

    Return pan used to sear steaks to medium-high heat. Add demi-glace, Dijon, and ¼ cup water to hot pan. Cook, stirring occasionally, until sauce is thick enough to coat back of a spoon and simmering, 2-3 minutes. Remove pan from burner and stir in half the truffle oil. Taste, and add more if desired.

  • 6

    Plate the Dish

    Place a serving of peas and potatoes on a plate. Add sauce to plate. Place steak in sauce.
