Ingredients:

  • 4 lb (1.8 kg) boneless, trimmed Strip Loin Roast
  • 2 Tbsp (30 g) Kosher Salt (flaky)
  • 1 Tbsp (15 g) Fresh Black Pepper (coarsely ground)
  • 1 Tbsp (15 ml) Fresh Rosemary (finely chopped)
  • 1 Tbsp (15 ml) Fresh Thyme Leaves
  • 3 large cloves (~15 g) Garlic (minced or paste)
  • 2 Tbsp (30 ml) Olive Oil or Beef Dripping
  • 1/2 cup (120 ml) Crème Fraîche or Sour Cream
  • 2–3 Tbsp (30–45 ml) Prepared Horseradish (drained)
  • 1 tsp (5 ml) Lemon Juice (freshly squeezed)
  • 1 Tbsp (15 ml) Chives (finely snipped)
  • Pinch of Salt & Pepper (To taste)

Instructions:

  1. Trim and Tie the Roast: Use butcher's twine to tie the roast firmly every 1.5 inches (4 cm). This ensures a uniform shape, leading to even cooking.
  2. Dry Brine: Pat the entire roast bone dry with paper towels. Rub aggressively with the Kosher Salt only (this is the dry brine).
  3. Chill (The Secret Weapon): Place the roast uncovered on the rack in the refrigerator for at least 1 hour, or preferably overnight. This draws moisture out of the surface, ensuring a perfect crust.
  4. Prepare the Rub: In a small bowl, combine the pepper, minced garlic, rosemary, thyme, and olive oil/dripping.
  5. Apply the Rub: Remove the roast from the fridge 30 minutes before cooking. Pat off any visible moisture (the salt has already done its job). Rub the garlic-herb mixture evenly over all surfaces.
  6. Preheat Oven (Low): Preheat your oven to 250°F (120°C). Place the prepared roast on the rack in the roasting pan.
  7. Insert Thermometer: Insert the probe thermometer into the very centre of the thickest part of the roast, ensuring it does not touch bone or fat.
  8. Slow Cook: Roast until the internal temperature reaches the target pre-sear temperature (120°F/49°C recommended for medium-rare). This usually takes 60–90 minutes.
  9. Rest and Preheat (High): When the target temperature is reached, immediately remove the roast from the oven and transfer it to a cutting board. Tent lightly with foil. Increase the oven temperature to 500°F (260°C).
  10. The Sear: Once the oven is ripping hot, return the roast to the oven (un-tented) for 5–10 minutes, or until a deep, dark brown crust is formed. Watch closely to avoid burning the herbs.
  11. Final Rest (Crucial): Remove the roast from the oven. Transfer it to a clean cutting board and tent it tightly with foil. Allow it to rest for a full 20 minutes.
  12. Make the Sauce: While the meat rests, quickly whisk together the crème fraîche, horseradish, lemon juice, chives, salt, and pepper. Chill until serving.
  13. Carve and Serve: Remove the twine. Slice the roast against the grain into 1/2-inch (1.2 cm) thick slices. Serve immediately with a generous dollop of Horseradish Cream.
