Remove the roast from the refrigerator 30-60 minutes before cooking to bring it to room temperature. Preheat the oven to 450°F (230°C) and position the rack in the middle.
In a small bowl, mix together the olive oil, salt, pepper, garlic, rosemary, thyme, and oregano to create a paste.
Rub the herb paste all over the roast, ensuring it's evenly coated.
If using, tie the roast with kitchen twine at 1-inch intervals to help it maintain its shape during cooking.
Place the roast fat-side up on a rack in a roasting pan. Insert an oven-safe meat thermometer into the thickest part of the roast, not touching fat or bone.
Place the roasting pan in the preheated oven and cook for 15 minutes to sear the exterior.
Reduce the oven temperature to 325°F (165°C) and continue roasting until your desired doneness is reached. As a general rule, plan for these cooking times per pound:
Rare (125°F): 15-17 minutes
Medium-rare (135°F): 18-20 minutes
Medium (145°F): 21-23 minutes
Once your roast reaches the target temperature, remove it from the oven, tent loosely with foil, and let it rest for 15-20 minutes before slicing.
Transfer the rested roast to a cutting board and remove the twine, if used. Using a sharp knife, slice the roast against the grain for maximum tenderness.
Arrange the slices on a warm platter, spoon any accumulated pan juices over the top, and serve immediately with your choice of sides.
