If you like filet mignon you will love this prime beef tenderloin that is reverse seared. The seasoning is simple and cooking the beef tenderloin over charcoal adds just a hint of smoky flavor.
Setup smoker for indirect heat at 350°F. Fold the tail section back over the tenderloin and tie it in place with string.
Cook the tenderloin over indirect heat to an internal temperature of 108 - 112°F. Remove the roast, cover with foil and rest for 10 minutes.
Reconfigure the smoker for direct heat and raise the temperature to 550°F. Add the roast back to smoker and sear the outside (about 4 -5 minutes), rotating every minute or so. Remove and serve.
