How to Make Delia Smith Pumpkin Soup Recipe

Prepare the vegetables: Peel and deseed the pumpkin, then cut into even chunks so they cook at the same rate. Finely chop the onion and crush the garlic.
Cook the base: In a large heavy-based saucepan, melt the butter with the olive oil over medium heat. Add the onion and cook gently for 8 to 10 minutes until soft and translucent. Stir in the garlic and cook for another minute.
Add the pumpkin: Tip the pumpkin chunks into the pan and stir well so they are coated in the buttery onion mixture.
Simmer the soup: Pour in the vegetable stock and bring to a gentle boil. Reduce the heat, cover and simmer for 25 to 30 minutes until the pumpkin is completely tender.
Blend until smooth: Remove the pan from the heat and allow to cool slightly. Blend with a hand blender until smooth and velvety. Alternatively, blend in batches using a jug blender.
Add cream and seasoning: Stir in the milk or cream and add the nutmeg. Season generously with salt and freshly ground black pepper. Reheat gently without boiling.
Serve: Ladle into warm bowls and swirl with a little double cream. Finish with chopped herbs and a twist of black pepper.

Tips

How do I make the soup extra smooth?

Blend thoroughly while the soup is still warm and pass it through a sieve if you prefer an exceptionally silky finish.

Can I roast the pumpkin first?

Yes, roasting the pumpkin at 200°C for about 25 minutes before adding it to the soup deepens the flavour and adds a subtle sweetness.

What if my soup is too thick?

Add a splash of hot stock or boiling water and stir until you reach your preferred consistency.

How can I add more flavour?

A pinch of chilli flakes or a small piece of grated fresh ginger adds gentle warmth without overpowering the pumpkin.

FAQs

Can I use butternut squash instead of pumpkin?

Can I make this soup dairy free?

Simply replace the butter with olive oil and use a dairy free cream alternative or omit the cream entirely.

How do I thicken pumpkin soup naturally?

Simmer uncovered for a few extra minutes to reduce the liquid, or add a small peeled potato when cooking and blend it in.
