Remove the giblets and excess fat from the turkey. Pat the turkey dry with paper towels to remove moisture.
Rub the entire turkey with olive oil, ensuring it’s coated evenly.
In a small bowl, mix together the salt, black pepper, garlic powder, onion powder, paprika, thyme, rosemary, and cayenne pepper.
Rub the seasoning mixture all over the turkey, making sure to get it under the skin and inside the cavity.
Preheat your smoker or grill to a temperature of 225-250°F.
Add the wood chips to the smoker according to the manufacturer’s instructions, ensuring the smoke flavor will infuse into the turkey.
Place the turkey on the smoker rack, breast-side up. Close the lid and smoke the turkey for about 4 hours, or until the internal temperature reaches 165°F when measured in the thickest part of the breast and thigh.
During smoking, baste the turkey with a mixture of melted butter and olive oil every hour to keep the skin moist and flavorful (optional but recommended for extra richness).
Once the turkey is fully cooked, remove it from the smoker and let it rest on a tray or platter for about 20 minutes to allow the juices to redistribute.
Carve and serve with your favorite sides, such as mashed potatoes, green beans, or cornbread.
