Preheat your oven to 450°F.
Let the roast sit at room temperature for about an hour to warm up.
Mix olive oil, peppercorns, kosher salt, garlic, rosemary, and thyme in a small bowl.
Massage this mixture thoroughly over the entire surface of the roast.
Place the seasoned roast on a rack in a large roasting pan, fat side up.
Insert a meat thermometer into the thickest part of the roast without touching bone.
Roast in the oven for 45 minutes.
Reduce the oven temperature to 325°F and continue roasting.
Cook until the thermometer reads the desired level of doneness.
Remove the roast from the oven when it reaches 135°F for medium-rare.
Let it rest for at least 15 minutes before slicing.
