Set your pellet grill to 225°F. Let it fully preheat while you prep the bird. Use a fruitwood like apple or cherry for sweeter, mellow smoke, or hickory if you want something stronger and more assertive.
Remove giblets (if included), and pat the chicken completely dry with paper towels. Moisture is the enemy of crisp skin. Brush with olive oil and melted butter.
Mix all your dry spices in a bowl and coat the chicken thoroughly, don’t forget the underside and inside the cavity.
Stuff the cavity with lemon, onion, and thyme. Tie the legs together with kitchen twine to help the bird cook more evenly, but this step is totally optional.
Place the chicken breast-side up directly on the grill grates. Smoke at high smoke setting for 15 min. Increase the temp to 225°F and continue smoking for about 2.5 to 3 hours, or until the internal temperature hits 165°F in the thickest part of the breast and 175°F in the thigh.
If you want that golden, crispy skin, increase the grill temp to 375°F for the last 15 minutes of cooking, or broil briefly at the end.
Let the chicken rest for at least 15 minutes before carving.
Notes
Brine the chicken – wet brining keeps the chicken ultra juicy, dry brining gives you crispy skin.Dry the skin well – pat that chicken down with paper towels before seasoning.Use a meat thermometer – forget guessing. Pull the bird off the grill when the breast hits 165°F and thighs hit 175°F for juicy, fully cooked chicken.
