About this recipe
What is Roasted Harissa Cauliflower?
Roasted Harissa Cauliflower is a vegan dish where a whole cauliflower is coated in harissa — a spicy, smoky North African sauce made from chili peppers, garlic, and various spices.
The cauliflower roasts to perfection, resulting in a crispy, golden exterior while the inside remains tender.
The harissa sauce adds a fiery kick, while the creamy garlic yogurt and tahini drizzle balance out the heat, creating a flavour profile that’s both bold and comforting.
The History of Harissa and Cauliflower
Harissa is a staple in North African cuisine, especially in Tunisia, Morocco, and Algeria.
Its fiery depth and smokiness come from roasted chili peppers combined with spices like cumin, coriander, and garlic.
Originally used to flavour meats, fish, and vegetables, harissa has become increasingly popular worldwide, finding its way into modern vegan dishes.
Cauliflower, a vegetable that’s often seen as humble and understated, has gained a lot of love in the culinary world.
Roasting brings out its natural sweetness and adds texture, making it an ideal choice for a centrepiece dish like this.

Instructions
1. Prep and cook the cauliflower
Start by trimming any outer leaves from the cauliflower and the stem if needed.
Place the cauliflower head in a large pot of boiling water and cook for 7 minutes, just enough to soften slightly.
Drain and let the cauliflower steam dry for a few minutes.
2. Make the harissa garlicsauce
In a small bowl, mix the harissa paste, grated garlic, olive oil, and a pinch of salt.
This will be the flavourful coating for your cauliflower.
3. Coat the cauliflower
Once the cauliflower is dry and slightly cool, coat it with the harissa garlic sauce.
Use a brush or your hands to ensure every part is well-coated for maximum flavour.
4. Roast the cauliflower
Preheat your oven to 200°C (400°F).
Place the cauliflower on a lined baking tray and roast for 30-40 minutes until golden brown and crispy.
5. Prepare the garlic yogurt base
While the cauliflower is roasting, mix the vegan yogurt with minced garlic and a pinch of salt.
Spread this creamy garlic yogurt base on the bottom of your serving plate.
6. Assemble and garnish
Place the roasted cauliflower on top of the garlic yogurt base.
Drizzle with tahini, and garnish with freshly chopped spring onions or parsley for a fresh, herby finish.
FAQs
Can I make this recipe spicier or milder?
If you like your cauliflower extra spicy, feel free to add a little more harissa or use a spicy variety. If you prefer a milder heat, you can dial it back to suit your taste.
Can I use regular yogurt instead of vegan ones?
Of course! Regular yogurt works perfectly if you’re not strictly vegan. The garlic yogurt base adds a lovely cooling contrast to the spice.
Can I make this ahead of time?
Yes definitely! You can boil the cauliflower and make the harissa sauce ahead of time, keeping them separate until you're ready to roast. This makes it easier to throw together for a quick weeknight dinner.
What can I serve with this roasted cauliflower?
This roasted cauliflower is perfect as a main dish served with a grain like couscous or rice, but it also works great as a side dish for a larger spread.
How do I store any leftovers?
If you somehow manage not to eat it all in one go, leftover roasted cauliflower can be stored in the fridge for up to 3 days and reheated in the oven to maintain that crispy texture.
