Mix together all spices and season the chicken all over.
Fill the pellet basket with pellets.
Place the chicken, breast side up, on the grill.
Insert a meat probe in the thickest part of the breast.
Close the door. Set the dial to Smoker. Set the temperature to 350°F. If you have the Ninja Woodfire Pro, you can use the built-in temperature probe to monitor the meat temperature, so set it to 165°F. The machine will turn off when the meat reaches that temperature.
If you don’t have the Pro, you should set the timer for 1 hour of cook time and then about 15 minutes before, start to check it with an instant read digital meat thermometer.
Select START/STOP to begin cooking.
When the chicken is at 165°F, remove it from the grill and rest for 15-20 minutes before carving.
