Rosemary Garlic Beef Tenderloin Recipe

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.

  • Place oven rack in center position and preheat oven to 350°F.
