In a large frying pan sear the meat on all sides until a nice crust appears.
Pre-heat oven to 425 degrees.
Place the beef on a rack in a shallow roasting pan and roast uncovered for about 40 minutes turning once during the cooking.
Remove beef from the oven and let stand around 20 minutes before slicing. Roast should be medium-rare.
