Put the tenderloins on a rack in a roasting pan, and roast them in a 450Â°F oven. After about 15 minutes, check the internal temperature with a probe thermometer. For a tenderloin that's medium-rare, look for an internal temperature of 120Â°F. For medium, the internal temperature should be 125Â°F.When the tenderloin is cooked the way you like it, let it rest at room temperature for 15 minutes before slicing. This will let the juices redistribute so the meat is juicy all over.or medium, the internal temperature should be 125Â°F.

A beef roast cooked to medium-rare should have an internal temperature of 145Â°F - 150ÂºF after the resting period, and a roast cooked to medium should have an internal temperature of 150Â°F to 160ÂºF. (See the note below). See Beef Doneness for more information on proper cooking temperatures.llow the beef to roast at 450Â°F for 45 minutes and then begin checking the internal temperature of the meat with a meat thermometer. Continue roasting the meat until the internal temperature has reached 5 or 10 degrees below the desired doneness.
