Remove the turkey from the packaging and discard any giblets inside. Pat dry the turkey with a paper towel.
With the breast-side up, sprinkle the salt all over the surface of the turkey, then flip over and coat the underside.
Place the turkey on a large baking sheet or tray with a lip and cover with plastic wrap. Place it in the fridge.
Dry brine it for 24 hours to 2 days before cooking. Rub off any excess salt with a paper towel and place the turkey in a roasting tray.
Preheat your smoker to 225-250°F (107-121°C). Place the turkey in the roasting tray in the smoker and close the lid. Aim for an internal temperature of 165°F (75°C). It will take approximately 30 minutes per pound.
