In a large saute pan, heat the oil until very hot and saute the meat on all sides. Season with salt and black pepper. Let the meat brown slightly. Place in the hot oven for 15 to 20 minutes for rare to medium. (20 minutes if beef is hot 25 minutes if beef is room temperature. See note Remove from oven and let rest at room temperature or in a lukewarm place for 15 minutes before carving. This is important to allow the juices concentrated in the center to permiate all around the meat. Special Note; you can sear this 2 to 3 hours ahead of the roasting time.
