This is the ultimate romantic dinner, offering a melt-in-your-mouth texture and a sophisticated flavor profile that defines luxury dining.

🥗 Ingredients

The Beef

  • 16-20 ounces Center-cut Beef Tenderloin (Chateaubriand) (trimmed of all silver skin and tied with kitchen twine)
  • 2 tablespoons Unsalted Butter (at room temperature)
  • 1 teaspoon Kosher Salt (or to taste)
  • 1 teaspoon Black Peppercorns (freshly cracked)
  • 1 tablespoon Olive Oil (high smoke point oil)

Béarnaise Reduction

  • 1/4 cup Dry White Wine (such as Sauvignon Blanc)
  • 2 tablespoons White Wine Vinegar (high quality)
  • 1 piece Shallot (minced very finely)
  • 2 tablespoons Fresh Tarragon (stems reserved, leaves chopped)
  • 1/2 teaspoon Black Peppercorns (crushed)

The Sauce Emulsion

  • 3 large Egg Yolks (at room temperature)
  • 1 cup Unsalted Butter (melted and kept warm (clarified is best))
  • 1 teaspoon Lemon Juice (freshly squeezed)
  • 1 pinch Salt (to taste)

👨‍🍳 Instructions

  1. 1

    Remove the beef tenderloin from the refrigerator at least 45 minutes before cooking to bring it to room temperature; this ensures even roasting.

  2. 2

    Preheat your oven to 400°F (200°C). Pat the beef completely dry with paper towels and season generously on all sides with kosher salt and cracked black pepper.

  3. 3

    In a heavy, oven-proof stainless steel or cast-iron skillet, heat the olive oil over medium-high heat until it begins to shimmer. Sear the beef for 2-3 minutes per side until a deep golden-brown crust forms everywhere.

  4. 4

    Add 2 tablespoons of butter to the skillet, let it foam, and spoon it over the beef. Transfer the entire skillet to the preheated oven.

  5. 5

    Roast the beef until an instant-read thermometer inserted into the thickest part registers 125°F (52°C) for rare or 130°F (54°C) for medium-rare. This typically takes 12-18 minutes depending on thickness.

  6. 6

    While the beef roasts, prepare the reduction: In a small saucepan, combine wine, vinegar, shallots, crushed peppercorns, and tarragon stems. Simmer over medium heat until reduced to about 2 tablespoons of liquid.

  7. 7

    Strain the reduction through a fine-mesh sieve into a heat-proof glass bowl, discarding the solids. Let it cool slightly.

  8. 8

    Set the bowl over a pot of barely simmering water (bain-marie), ensuring the bottom of the bowl doesn't touch the water. Whisk in the egg yolks and 1 tablespoon of water.

  9. 9

    Whisk vigorously and constantly until the yolks thicken and double in volume, reaching a ribbon-like consistency. Do not let them scramble.

  10. 10

    Slowly drizzle in the warm melted butter in a thin, steady stream while whisking constantly. The sauce should become thick, glossy, and emulsified.

  11. 11

    Remove from heat and stir in the chopped tarragon leaves, lemon juice, and a pinch of salt. Keep the sauce in a warm spot (not hot) until ready to serve.

  12. 12

    Once the beef is done, remove it from the oven and transfer to a carving board. Tent loosely with foil and let it rest for at least 10-15 minutes to allow juices to redistribute.

  13. 13

    Remove the kitchen twine. Slice the Chateaubriand into thick medallions (about 1 to 1.5 inches thick) and serve immediately with a generous spoonful of Béarnaise sauce.

💡 Chef's Tips

Always use a meat thermometer; the window between perfect medium-rare and overdone is very small with tenderloin. If your Béarnaise sauce begins to break or curdle, whisk in a teaspoon of warm water to bring the emulsion back together. Clarifying your butter (removing the milk solids) will result in a much more stable and professional-grade sauce. Don't skip the resting period for the meat; cutting it too early will cause all the flavorful juices to run out onto the board. Keep the Béarnaise warm in a thermos if you aren't serving it immediately—it cannot be easily reheated if it gets cold.

🍽️ Serving Suggestions

Pair with classic Château Potatoes (potatoes turned into small olive shapes and sautéed in butter). Serve with steamed or butter-glazed asparagus spears for a bright, crunchy contrast. A full-bodied Bordeaux or a peppery Cabernet Sauvignon complements the richness of the beef perfectly. Start the meal with a light Frisée salad with a lemon vinaigrette to cleanse the palate. For a truly decadent presentation, serve alongside roasted bone marrow.
