Hugh Fearnley-Whittingstall’s roast cauliflower and cashew soup recipe
Pack in the plants with this comforting soup.
“This is a deliciously creamy white soup, packed with lots of lovely alliums (leek, onion, garlic), which get roasted with the cauli,” says Hugh Fearnley- Whittingstall.
If you have time, leave the cashews to soak for a few hours to soften – they’ll blend to a smoother finish.
“The garlic topping is a great addition and can be made ahead, but it’s by no means essential. ”
Creamy roast cauliflower and cashew soup
Ingredients
(Serves 4)
100g cashew nuts
1.2–1.5litres hot vegetable stock
1 large cauliflower (about 1.5kg), trimmed and cut into small florets, leaves kept
2 leeks, trimmed and cut into chunks
1 large onion, roughly chopped
3 celery sticks, roughly chopped
1tsp cumin seeds
2tbsp oil or melted fat
5 sprigs of thyme, leaves picked
Sea salt and black pepper
Garlic oil topping:
3tbsp extra virgin olive oil
2 garlic cloves, finely sliced
2tbsp sunflower or pumpkin seeds (or a mix)
A pinch of dried chilli flakes
To finish:
A small handful of chives, finely chopped, and/or parsley
Method
1. Put the cashews into a bowl, pour on 1.2 litres hot stock and leave to soak for at least an hour.
2. Preheat the oven to 190°C/170°C Fan/Gas 5.
3. Put the cauliflower florets into a large roasting tray, along with their roughly chopped leaves (if they’re in good nick). Add all the other veg and the cumin seeds. Add the oil or fat, season well with salt and pepper and toss the veg to coat lightly.
4. Transfer the roasting tray to the oven and roast for 20–25 minutes until all the veg are tender and golden.
5. In the meantime, make the topping. Put the extra virgin olive oil into a small saucepan with the garlic, seeds, chilli flakes and a pinch of salt. Place over a medium heat and heat gently for just a minute or two until the garlic starts to turn pale golden. Immediately take off the heat and pour the garlicky oil into a bowl. Leave to infuse until the soup is ready.
6. Scrape the contents of the roasting tray into a jug blender, add the thyme leaves and tip in the cashew nuts, along with their soaking liquor. Blitz until smooth. Return the soup to the saucepan and reheat gently, without boiling. (Or you can blitz the soup directly in a saucepan, using a stick blender, as you reheat it.) Either way, add a dash more stock to thin the soup a little if it seems too thick.
7. Ladle the soup into warmed bowls and top each serving with a trickle of the crispy garlic oil and a sprinkle of chopped chives and/or parsley.
