I hope to do my turkey on the Traeger again this year. I will plan to brine it for 24 hours before cooking, but I do not plan to inject it. The turkey is a Butterball which is supposed to be injected at the factory. If I were doing another brand of turkey, I might inject it.
Right before cooking, I will dry the turkey inside and out, rub it with soft butter to make the skin crispy and then apply seasoning inside and out. I have some sprigs of rosemary, thyme and oregano that I will place inside the turkey along with pieces of onion and apple.
I plan to smoke it at 225F for a couple of hours and then boost the grill temp to 325F to finish the bird off at an internal temp of 165F. I have a bag of pecan blend pellets that I will probably use to fuel the Traeger.
