Roasting Whole Beef Tenderloin

In a roasting pan heat a tablespoon of oil and brown the meat. Roast it at 500°F/260°C for 25-35 minutes, turning it over every eight to ten minutes. For rare meat, the thermometer should register 125°F/51°C, and for medium-done, 140°F/60°C. Let it stand before carving.
