Oven-Roasted Filet Mignon with Mustard & Worcestershire

By Marie Lefebvre · Updated October 26, 2026

A whole filet mignon slowly roasted under a bold mustard and Worcestershire crust until perfectly golden and juicy inside. Effortless to prepare yet impressive enough for a special occasion. The trick is slicing it and letting it rest back in its own pan juices — every bite is packed with flavor.

🛒 Ingredients

10 servings

10
  • 1 whole filet mignon (chain removed)
  • 4 tablespoons Dijon mustard
  • 3 tablespoons Worcestershire sauce
  • 2 garlic cloves, pressed
  • Salt and freshly ground black pepper

Directions

  1. 1

    Preheat oven to 350 °F (180 °C). Remove the filet from the fridge 20 minutes before cooking.

  2. 2

    Rub the pressed garlic all over the meat, pressing the pieces into the surface so they stick.

  3. 3

    Generously coat the entire filet with mustard, massaging it in well — the roast should turn a bright yellow.

  4. 4

    Drizzle heavily with Worcestershire sauce and rub again to fully coat.

  5. 5

    Place in a roasting dish, cover tightly with aluminum foil and roast for 1 hour.

  6. 6

    Remove the foil and continue roasting until the surface is golden brown and the juices have reduced but not dried out — keep a small pool of liquid in the pan.

  7. 7

    Remove from oven, slice into medallions, return the slices to the pan juices briefly, then serve with white rice and butter-herb sautéed potatoes.

💡 Chef's Tip

For deeper flavor, marinate the filet with mustard and garlic overnight in the fridge. A meat thermometer should read 145 °F (63 °C) at the center for medium doneness.
