Heat the oven to 180C/160C fan/gas 4. Cut the squash in half lengthways and scoop out the seeds. Brush a little oil over the cut surface and season with salt and pepper. Put the squash cut-side down on a baking tray lined with baking parchment and roast for 30 mins.

Carefully turn the squash halves over and bake for another 15 mins, until tender and starting to caramelise. Leave to cool for 5 mins, then use a fork to pull into long, spaghetti-like strands. Use in place of pasta, in salads, or alongside roasted fish or meat.
