Butternut Squash Soup

2-3 servings

Ingredients:

1 medium butternut squash (or half a large one), peeled and chopped
3 leeks, white parts only, roughly chopped
950ml  | about 4 cups vegetable or chicken stock
120ml | 1/2 cup milk - more if soup is too thick
130g | 4.5 oz cooked chestnuts (canned or vacuum packed)
Salt and pepper to season
4-5 tbsp freshly grated Parmesan cheese
2 tbsp pouring cream (optional)
1 tbsp butter

Instructions:
1. Put the butter in a medium saucepan and heat until foamy. Sauté the chopped leeks for 3-4 minutes until soft. Add the butternut squash and chestnuts and continue to cook for a few more minutes. Season with salt and pepper.
2. Add the stock and simmer on medium-low heat until the squash is cooked through and liquid is reduced - about 20-25 minutes.
3. Once the squash is completely tender, put the soup in a blender or food processor and blitz until smooth.
4. Return to the pot, add the milk and simmer for a few minutes on low heat (it will bubble dangerously). Stir in the cheese if using.
5. Serve with a a little cream swirled on top.
