  4. Bake at 450 degrees F (230 degrees C) for 20 minutes, then reduce heat to 400 degrees F (200 degrees C) and roast for 55 to 60 more minutes for medium rare. The internal temperature should be at least 145 degrees F (63 degrees C) when taken with a meat thermometer. Let the roast rest for about 10 minutes before carving.
