Pat the turkey dry with paper towels, inside and out. This helps the skin crisp up during smoking.
In a small bowl, combine olive oil, salt, pepper, garlic powder, onion powder, paprika, thyme, and rosemary. Rub the mixture all over the turkey, including under the skin of the breast.
Preheat your smoker to 275°F (135°C). Add your chosen wood chips according to your smoker's instructions. Ensure you have enough fuel (charcoal, wood, or propane) for the entire smoking process.
Place the seasoned turkey directly on the smoker grate, breast side up. Close the smoker lid and maintain a consistent temperature.
Use a meat thermometer to monitor the internal temperature of the turkey. Insert the thermometer into the thickest part of the thigh, avoiding the bone.
Smoke the turkey for approximately 3-4 hours, or until the internal temperature reaches 165°F (74°C). The exact time will depend on the size of your turkey and the consistency of your smoker's temperature.
Once the turkey reaches 165°F (74°C), remove it from the smoker and let it rest for at least 30 minutes before carving. This allows the juices to redistribute, resulting in a more moist and flavorful bird.
After resting, carve the smoked turkey and serve with your favorite thanksgiving sides.
