Preheat the oven to 200°C (gas mark 6-7).
Remove the leaves and stalk from the cauliflower, but keep it whole.
Place the cauliflower on a large sheet of greaseproof paper, then drizzle over plenty of olive oil. Season with salt and pepper and then add the spices.
Wrap the cauliflower in greaseproof paper as you would a papillote.
Place on the baking sheet and bake for 50 minutes.
Check whether the cauliflower is cooked using a knife.
