How to cook deliciously - Butternut squash soup

1 . Stage

Heat the oven to 200C/180C fan/gas 6.

2 . Stage

Cut the squash into large cubes, about 4cm/1½in across, then toss in a large roasting tin with 1 tbsp of the olive oil.

3 . Stage

Roast for 30 mins, turning once during cooking, until golden and soft.

4 . Stage

While the butternut squash cooks, melt the butter with the remaining 1 tbsp olive oil in a large saucepan, then add the onions, garlic clove and three-quarters of the chillies.

5 . Stage

Cover and cook on a very low heat for 15-20 mins until the onions are completely soft.

6 . Stage

Tip the butternut squash into the pan, add the stock and crème fraîche, then whizz with a stick blender until smooth. For a really silky soup, put the soup into a liquidiser and blitz it in batches.

7 . Stage

Return to the pan, gently reheat, then season to taste. Serve the soup in bowls with swirls of crème fraîche and a scattering of the remaining chopped chilli.
