Ingredients
  

  • 1 whole center-cut beef tenderloin, about 3-4 lbs (1.4-1.8 kg), trimmed and tied
  • 2 tbsp Avocado Oil (30 ml)
  • 2 tbsp Fresh Thyme (4g), finely chopped
  • 1 tbsp Fresh Rosemary (2g), finely chopped
  • 4 cloves Garlic, minced
  • 1 tbsp Kosher Salt (18g) To taste
  • 2 tsp Black Pepper (4g) To taste
  • 1 Coarse Sea Salt Flakes, for finishing
  • 1/2 cup Sour Cream (120g)
  • 3 tbsp Prepared Horseradish (45g), drained
  • 2 tbsp Fresh Chives (8g), finely chopped
  • 1 tsp Lemon Juice (5ml)
  • Salt and Pepper, to taste

Equipment

  • 1 Large Cast-Iron or Stainless Steel Skillet
  • 1 Roasting Pan with a Rack
  • 1 Instant-Read Meat Thermometer

Method
 

Prepare the Tenderloin & Herb Rub
  1. Preheat oven to 400°F (200°C). Pat the tenderloin dry with paper towels. Tie with butcher's twine at 1.5-inch intervals if not already done.
  2. In a small bowl, mix chopped thyme, rosemary, and garlic. Season the tenderloin generously with kosher salt and pepper, then rub the herb mixture all over the beef.
Sear and Roast
  1. Heat avocado oil in a large skillet over medium-high heat until shimmering. Sear the tenderloin for 2-3 minutes per side until a dark brown crust forms on all sides.
  2. Transfer the seared tenderloin to a roasting rack. Insert a meat thermometer into the thickest part and roast until it reaches your desired temperature (e.g., 130-135°F for medium-rare).
Rest, Sauce, and Serve
  1. Transfer the roast to a cutting board, tent with foil, and let it rest for 15-20 minutes. The internal temperature will continue to rise slightly.
  2. While the beef rests, whisk together sour cream, prepared horseradish, chives, and lemon juice in a small bowl. Season with salt and pepper to taste.
  3. Remove twine, slice the tenderloin against the grain, and arrange on a board. Garnish with coarse sea salt flakes and fresh thyme sprigs. Serve with horseradish sauce.

Notes

Allow the meat to sit at room temperature for about an hour before cooking for a more even roast.
Use a meat thermometer for guaranteed results; it's the most reliable way to prevent overcooking.
Don't skip the resting period! It's crucial for keeping the meat juicy.
