Prepare the barbecue for indirect cooking over medium heat (190° to 230°C). If using a Weber® Q barbecue, set up your barbecue with a convection tray and a trivet.
Wash the cauliflower. Remove any unwanted leaves and, if needed, cut the base of the stalk to create a flat surface.
In a bowl mix together the butter, crushed garlic, salt, pepper, Parmesan, rosemary, and thyme. Spread the butter mixture over the cauliflower. Sprinkle the dukkah evenly over the cauliflower.
Roast the cauliflower over indirect medium heat, with the lid closed, for 1 to 1½ hours. If the cauliflower starts to darken, cover with aluminium foil until cooked through to your liking.
