1. Bring to Room Temperature
Remove the roast from the refrigerator 1–2 hours before cooking. This ensures even cooking.
2. Season Generously
Rub the roast with olive oil, garlic, rosemary, thyme, salt, and pepper, coating all sides well.
3. High-Heat Start
Preheat oven to 230°C (450°F). Place roast fat-side up on a rack in a roasting pan. Roast for 20 minutes to develop a crust.
4. Slow Roast
Reduce oven temperature to 165°C (325°F) and continue roasting until desired doneness:
-
Rare: 48–50°C (120–122°F)
-
Medium-rare: 52–54°C (125–130°F)
-
Medium: 57–60°C (135–140°F)
This usually takes 15–17 minutes per pound.
5. Rest
Remove roast and tent loosely with foil. Rest for 20–30 minutes before carving to lock in juices.
