How to BBQ How Long to Smoke a Whole Chicken
1
Spatchcock the chicken for faster, more even cooking (optional but recommended). Otherwise, pat dry and tuck the wings.
2
Season under and over the skin. A mix of paprika, garlic powder, onion powder, thyme, salt, and pepper works well.
3
Set smoker to 135°C (275°F). Higher temps give crispier skin. At 110°C the skin can be rubbery.
4
Place chicken breast-side up on the grate. Insert a probe into the thickest part of the thigh.
5
Smoke until the thigh reaches 74°C (165°F). Breast meat may finish sooner — that's fine.
6
For crispy skin, increase temperature to 175°C (350°F) for the last 15 minutes, or finish on a hot grill.
7
Rest for 15–20 minutes before carving.
Pro Tips
- Smoke at 135°C (275°F) for the best balance of smoke flavour and crispy skin.
- Spatchcocking reduces cook time by 30–40% and gives more even results.
- Dry brine (salt the skin) the night before for the crispiest skin.
- Fruitwood (apple, cherry) gives the best flavour on chicken. Avoid strong woods like mesquite.
- The breast will cook faster than the thigh. Shield the breast with foil if needed.
Resting Time
Rest for 15–20 minutes after removing from the BBQ. This allows juices to redistribute for a juicier result.
Frequently Asked Questions
How long to smoke a whole chicken at 110°C (225°F)?
A 2kg chicken takes 3.5–4.5 hours at 110°C. However, the skin tends to be rubbery at this temperature. We recommend 135°C for better skin.
How do you get crispy skin on smoked chicken?
Dry brine overnight, smoke at 135°C (275°F) or higher, and finish at 175°C (350°F) for the last 15 minutes. Avoid basting — moisture softens skin.
What wood is best for smoking chicken?
Apple and cherry are the top choices — mild, sweet, and complementary. Pecan is also excellent. Avoid mesquite or heavy hardwoods that can overpower poultry.
