How to Make Roast Beef Tenderloin:

Note:
Actual cooking time will vary depending on a number of factors, including the starting internal temperature of the beef. Therefore, allow the beef to rest at room temperature for 20-30 minutes before roasting and use an instant-read thermometer to check for doneness. For medium-rare, remove from oven at 140°F. The temperature will rise to 145°F as it rests.
