Preheat oven to 450°F (230°C).
In a small bowl, mix olive oil, butter, garlic, salt, pepper, rosemary, and thyme.
Pat the roast dry with paper towels. Rub the seasoning mixture evenly over all sides.
Place the roast fat-side up on a rack in a roasting pan.
Roast at 450°F for 20 minutes to develop a crust.
Reduce oven temperature to 325°F (165°C) and continue roasting until desired doneness:
Rare: 120–125°F (about 12–14 minutes per pound)
Medium-rare: 130–135°F
Medium: 140–145°F
Remove roast from oven, tent loosely with foil, and rest for 20–30 minutes before slicing.
