This pumpkin chestnut soup is creamy, delicious, and perfectly warming! All pumpkin soups are sweet and tasty but they sometimes tend to taste a little bland. I boosted the taste of this soup with a bit of ginger, brown butter, chestnuts and to break the sweetness – a little bit lemon juice. I served it with swirls of yogurt and topped with lightly caramelized chestnuts and crunchy, toasted pecans. Doesn’t it sound wonderful? This soup is really worth a try!
This soup is made with really basic pumpkin soup ingredients:
- Pumpkin puree or roasted pumpkin. You can also use canned pumpkin puree or roast the pumpkin yourself, it’s really quick and easy. You can use either pumpkin or butternut squash for this recipe.
- Broth – you can use vegetable or chicken broth.
- Cream – for little extra creaminess.
- Aromatics: onion, ginger, and garlic.
- Surprise ingredient: chestnuts. You’ll need already cooked or roasted, and peeled chestnuts. Here you can read a helpful article about how to roast chestnuts. Chestnuts are not nuts, despite what the name suggests! Chestnuts taste similar to pumpkin/sweet potato and beans. They have a nutty, earthy taste and go with pumpkin perfectly.
- Brown butter – onion, ginger, garlic, and chestnuts are cooked in butter, which is transforming it into brown butter – it adds even more flavor to the soup. What is brown butter? Brown butter is simply butter, that has been cooked for a couple of minutes until slightly caramelized, it‘s very fragrant and nutty, goes perfectly with chestnuts and pumpkin!
- A very important ingredient that finishes the soup – lemon juice. It breaks the sweetness of the soup and it really can not be omitted!
Optionally you could make caramelized chestnuts to serve on top of the soup – you will only need sugar, butter, and chestnuts.
How to make pumpkin chestnut soup step by step:
Make the caramelized chestnuts:
- Add the sugar into a small pot.
- Heat the sugar over low heat until caramelized – it will turn golden brown and start bubbling. Make sure to use low heat and keep an eye on the sugar as it can quickly burn and be bitter.
- Add the butter and stir until melted.
- Add lightly crushed chestnuts.
- Toss until coated in caramel.
Make the soup:
STEP 1: Melt the butter in a large pot, add the onion and cook for about 5 minutes, or until the onion is soft.
STEP 2: Add finely chopped garlic and ginger, then the chestnuts.
STEP 3: Cook for a couple of minutes, stirring from time to time until the butter will turn golden brown and all the aromatics are fragrant.
STEP 4: Add the pumpkin puree or roasted pumpkin chunks and the broth. Bring to a boil and cook partially covered over low heat for about 15 minutes.
STEP 5: Add the cream and take the pot off the heat.
STEP 6: Puree the soup until smooth. Season to taste with salt, pepper, and lemon juice.
Serve it with plain yogurt, caramelized chestnuts, and toasted nuts (pecans or walnuts).
