Smoked beef tenderloin is a delicious and easy-to-make dish that is perfect for any occasion. This Traeger beef tenderloin recipe is simple & made in just a couple of hours.
Season the beef tenderloin with salt, pepper, and rosemary.
Place the beef directly onto the grill grate in your preheated smoker. Use a leave-in meat thermometer to gauge the internal temp of the meat as it smokes. Close the lid and smoke the beef at 190°F for about 75 to 90 minutes.
The cooking time will depend on your desired doneness of the beef. For medium rare, I smoked the beef until it reached 120°F internal temp.
While the beef tenderloin is smoking, preheat your grill to use it for a reverse sear for the beef. You can also do this in a hot skillet or in the oven broiler.
Once the beef is done smoking, place the beef onto the hot grill and sear on both sides for about one minute each. Once the beef reaches 130 degrees F, remove it from the grill and allow it to rest for 15 minutes. The internal temperature by the end of the resting time will be about 135°F. Slice and serve.
