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.

Traditional guidelines for doneness state that beef cooked very rare, rare, or medium-rare should have an internal temperature ranging between 115ÂºF to 140Â°F.Many people prefer beef cooked rare (especially steak), but this decision is up to the consumer and is certainly not recommended by the USDA.hole beef cuts usually have bacteria only on the surface, but it is possible for harmful bacteria to be present in the internal portions, so cooking the meat to an internal temperature of 145Â°F is sufficient to kill the bacteria.
