Load your Pit Boss grill hopper with your prefered wood pellets and turn it on.
After running the Pit Boss through the startup process, set the temperature to 325°F and set it up for indirect heat, if applicable.
Place the turkey in the rack and pan on the pellet grill. If using a smoker box, place it next to the pan but away from the pellet grill temperature probe.
Rotate the pan every 30-60 minutes. For crispy skin, do not baste the turkey while it is cooking.
If the wings or legs start to get too brown, wrap them in aluminum foil.
If the breast meat is cooking faster than the thigh meat, remove the turkey in the rack from the aluminum pan and place the rack onto the grill grates in the center of the grill over the firepot.
Cook 3-4 hours, depending on the size of your turkey, until the breast reaches an internal temperature of 160°F, and the thighs reach an internal temperature of 170°F on an instant read thermometer. Make sure to test the temperature in many spots throughout the cook to ensure even cooking.
Remove the smoked turkey from the Pit Boss and let it rest 30 minutes to reach a final internal temperature of 165°F in the breasts and 175°F in the thighs.
Carve and serve.
