A vegetarian one pot recipe for autumn from ” Stirring Slowly” by Georgina Hayden.
Peel the butternut squash and cut into 1½ cm pieces.Grind the coriander seeds and chilli flakes to a fine powder in a mortar and pestle. Finely slice the pancetta if using.
Place a large saucepan on a medium-low heat and add a good glug of olive oil. Fry the pancetta for a few minutes, until golden, then add the sliced garlic for a minute before adding the chopped butternut squash and ground spices. Fry for 4-5 minutes, stirring occasionally, until lightly golden all over.
Pour in the stock, turn up the heat and bring to the boil. As soon as the stock starts to bubble, turn the heat down to low and cover with the lid. Cook for 10 minutes.
While the squash is cooking, wash the cavolo nero or chard, discarding the woody stalks. Shred the leaves (if using chard, finely shred the stalk too). Pick the basil leaves and roughly chop them.
Once the squash is ready, stir in the pasta. The stock should just cover the pasta, but if not, add a little more boiling water - you want all the pasta to be submerged. Scatter over the shredded greens and bring back to the boil. Reduce the heat, cover the pan and cook for a couple of minutes less than the full cooking time according to the packet instructions, stirring occasionally.
When the pasta is ready, remove the lid, turn up the heat and continue to cook for a couple of minutes to reduce the stock. Remove the pan from the heat when there is still around 3cm of stock left in the bottom of the pan.
Squeeze in the juice from the lemon half and finely grate in the Parmesan. Add the chopped basil and stir everything for a minute till silky and smooth. You'll notice the longer it is off the hob and the more you stir, the creamier and thicker it will get. Season to taste and serve straight away.
