🥗 Ingredients

The Beef

  • 2 lbs Center-cut Beef Tenderloin (Chateaubriand) (trimmed of all silver skin and tied with kitchen twine)
  • 1.5 tablespoons Kosher Salt (more or less to taste)
  • 1 tablespoon Black Peppercorns (coarsely cracked)
  • 2 tablespoons Grapeseed Oil (or any high-smoke point oil)

Aromatics for Basting

  • 4 tablespoons Unsalted Butter (cold)
  • 4 sprigs Fresh Thyme
  • 2 sprigs Fresh Rosemary
  • 4 cloves Garlic (smashed)

Truffled Madeira Jus

  • 2 pieces Shallots (finely minced)
  • 1/2 cup Madeira Wine (Sercial or Verdelho preferred)
  • 1 cup Beef Demi-Glace (high-quality store-bought or homemade)
  • 1 teaspoon Truffle Oil (optional, for finishing)
  • 1 tablespoon Cold Butter (to emulsify the sauce)

👨‍🍳 Instructions

  1. 1

    Remove the beef tenderloin from the refrigerator at least 60 minutes before cooking to bring it to room temperature; this ensures even roasting.

  2. 2

    Preheat your oven to 250°F (120°C). This low-and-slow start (reverse sear) creates a perfectly uniform pink interior from edge to edge.

  3. 3

    Pat the beef extremely dry with paper towels. Season aggressively on all sides with kosher salt and the cracked black pepper, pressing the spices into the meat.

  4. 4

    Place the beef on a wire rack set over a rimmed baking sheet. Insert a meat thermometer into the thickest part of the roast.

  5. 5

    Roast in the oven until the internal temperature reaches 115°F (46°C) for rare or 120°F (49°C) for medium-rare. This usually takes 35-45 minutes.

  6. 6

    Remove the beef from the oven and tent loosely with foil. Let it rest for 10 minutes; the temperature will rise slightly.

  7. 7

    Heat the grapeseed oil in a heavy cast-iron skillet over high heat until it begins to shimmer and smoke slightly.

  8. 8

    Place the beef in the skillet and sear for 1-2 minutes per side until a deep, dark brown crust forms. Do not forget to sear the ends.

  9. 9

    Reduce heat to medium. Add the 4 tablespoons of butter, thyme, rosemary, and smashed garlic. Once the butter foams, spoon it continuously over the beef for 2 minutes.

  10. 10

    Remove the beef to a carving board and let it rest for another 5-10 minutes while you prepare the sauce.

  11. 11

    In the same skillet (discarding excess fat but keeping the brown bits), sauté the minced shallots for 1 minute until soft.

  12. 12

    Deglaze with the Madeira wine, scraping the bottom of the pan. Reduce the liquid by half.

  13. 13

    Stir in the demi-glace and simmer until the sauce coats the back of a spoon. Whisk in the final tablespoon of cold butter and truffle oil for a glossy finish.

  14. 14

    Remove the kitchen twine, slice the heart of fillet into thick 1.5-inch medallions, and serve immediately with the warm jus.

💡 Chef's Tips

Always use a meat thermometer; with a cut this expensive, precision is your best friend. If you cannot find demi-glace, reduce 2 cups of high-quality beef stock with a splash of soy sauce until it is thick and syrupy. Don't skip the resting periods; they are essential for keeping the juices inside the meat rather than on your cutting board. For the best crust, ensure the meat is bone-dry before it hits the hot pan. If the garlic or herbs start to burn during the basting phase, immediately remove them from the pan.

🍽️ Serving Suggestions

Pair with a full-bodied Bordeaux or a California Cabernet Sauvignon to cut through the richness. Serve alongside pommes purée (silky mashed potatoes) and butter-glazed heirloom carrots. A side of creamed spinach with a hint of nutmeg provides a classic steakhouse feel. For a lighter touch, serve with a simple watercress salad dressed in a lemon vinaigrette. Provide a small bowl of Maldon sea salt on the table for guests to sprinkle over the sliced meat.
