Ingredients

  • 1 onion
  • 1 butternut squash
  • 500g/1lb 2oz sweet potatoes, unpeeled, cut into 2.5cm/1in thick rings
  • 60ml/2fl oz olive oil
  • 1 tsp ground cinnamon
  • ½ tsp ground nutmeg
  • 1.5 litres/2 pints 13fl oz vegetable stock
  • 125ml/4oz marsala wine
  • salt and freshly ground black pepper
  • 125g/4oz blue cheese
  • 250ml/9fl oz buttermilk

Instructions

  • Preheat the oven to 200C/400F/Gas 6.
  • Place the onion, chopped butternut squash and sweet potato onto a baking sheet. Drizzle with oil and sprinkle with the cinnamon and nutmeg. Roast in the oven for 45 minutes to an hour, or until tender.
  • Allow the vegetables to cool slightly, then place half into a food processor and add 500ml/17fl oz of the vegetable stock. Blend to a purée and transfer to a large pan. Repeat with the remaining roasted vegetables and 500ml/17fl oz more of the stock - transfer the purée to the pan.
  • Add the remaining 500ml/17fl oz of vegetable stock to the food processor and stir to catch any remnants of the vegetable purée, then pour into the pan.
  • Add the marsala wine and season, to taste, with salt and freshly ground black pepper. Add a little more water if the soup is too thick for your liking.
  • For the buttermilk cheese sauce, place the blue cheese and buttermilk into a clean food processor and blend to a paste. Transfer the blue cheese sauce to a jug or bowl.
  • To serve, ladle the soup into bowls and drizzle some of the blue cheese into each bowl. Leave the sauce on the table for your guests to add more if they wish.
