Remove roast from the refrigerator. If the roast has a fat cap, score it in a cross-hatch pattern using a knife. Add salt evenly to all sides, pressing it into the meat with your fingertips. Let sit for 45 minutes
Preheat the oven to 450 degrees. Mix the garlic and peppercorns in a bowl and sprinkle the mixture on all sides of the meat
Add the roast to a roasting pan and put it on the middle oven rack. Cook for 15-20 minutes until the outside becomes lightly browned
Turn down the temperature to 350 degrees, and continue cooking for another 1-2 hours, depending on your preferred doneness level. The meat should be ready to remove from the oven when it reaches 125-130 degrees for medium rare
Cover the roast with aluminum foil and rest it at room temperature for 15 minutes. Slice against the grain just before serving
