Smothered in harissa paste and yoghurt and roasted in the oven, this vegan whole roasted cauliflower is truly wonderful. A beautiful centrepiece for a vegan feast but equally as good as a veggie side dish.

Despite really hating cauliflower as a child, it's now one of my favourite vegetables.
The secret to learning to love cauliflower? Roasting it.
Roasting cauliflower brings out all the flavour and none of the sogginess. Cauliflower takes to other flavours really well so adding herbs and spices is a good idea.

In this vegan whole roasted cauliflower recipe I've added harissa paste. This gives it a lovely deep spicy taste, which is utterly moreish.
What is harissa?
Harissa is a chilli paste. It originates from north Africa and the middle east and is widely used in the cooking of those regions.
Every harissa recipe varies slightly but ingredients usually include:
- chillies
- red peppers
- coriander
- cumin
- olive oil
- garlic
- caraway or fennel seeds
You can also get rose harissa, which tastes absolutely incredible and would work just as well in this recipe.

Is whole roasted cauliflower easy to make?
Yes - it's very easy to make this harissa roasted cauliflower recipe.
All you need to do is:
- mix the paste ingredients together
- rub the cauliflower into the paste until well coated
- cover with foil or a lid - and roast!
Why foil? The foil stops the outside of the cauliflower from burning before the middle is cooked. If you have a large enough ovenproof dish with a lid you can use that instead.
How long does it take to cook a whole roasted cauliflower?
Cooking times can vary. Roughly speaking, the larger your cauliflower the longer it will take to cook.
A small cauliflower will cook in 40-45 minutes, a large one could take an hour or more.
To check whether it is cooked through you will simply need to insert a sharp knife into the centre of the cauliflower. If it slides in easily then it's cooked through - if not return to the oven.
What to serve with whole roasted cauliflower
This is a wonderfully versatile dish.
Harissa roasted cauliflower goes equally well with a mezze style meal as with a roast dinner. It would look gorgeous as the centrepiece of a vegan Christmas dinner.
