Fillet Mignon

Demi Glace Butter Sauce

Truffle Mash Potato

Roasted Market Vegetables

Method

Fillet Mignon Preparation

  1. 1

    Herb Crust Preparation

    Finely chop the fresh herbs and mix with olive oil, salt, and black pepper. Rub this mixture all over the fillet mignon pieces.

  2. 2

    Searing the Fillet

    Heat a skillet over medium-high heat. Add a little olive oil and sear the herb-crusted fillet mignon for about 3-4 minutes on each side for medium-rare. Remove and let rest.

Demi Glace Butter Sauce Preparation

  1. 3

    Making the Sauce

    In the same skillet, lower the heat and add minced shallots. Sauté until translucent, then add the demi-glace and red wine. Reduce until slightly thickened, then whisk in the butter until melted and smooth.

Truffle Mash Potato Preparation

  1. 4

    Cooking the Potatoes

    Boil the chopped potatoes in salted water until tender, about 15-20 minutes. Drain and return to the pot.

  2. 5

    Mashing the Potatoes

    Add heavy cream, truffle oil, salt, and pepper to the potatoes. Mash until smooth and creamy.

Roasted Market Vegetables Preparation

  1. 6

    Roasting the Vegetables

    Preheat the oven to 400°F (200°C). Toss the mixed vegetables with olive oil, salt, and pepper. Spread on a baking sheet and roast for 20-25 minutes until tender and slightly caramelized.
