Pro Tips
- Butterflied leg cooks faster and more evenly — great option for BBQ.
- Stud garlic directly into the meat via small cuts for maximum flavour.
- Use indirect heat — direct will char the outside and leave the centre raw.
- A 2kg bone-in leg takes about 1.5–2 hours.
Resting Time
Rest for 15–20 minutes after removing from the BBQ. This allows juices to redistribute for a juicier result.
