You already know by now that I love chestnuts, so making a chestnut soup is only logical. I honestly can’t get enough of it just like roasted chestnuts! It’s sweet, nutty and a little earthy, and so smooth and velvety that a bowl of it with some crusty bread is all I need on a cold evening.
It sounds like something that would take you all afternoon, with roasting and peeling and burnt fingers. But in France, most people don’t bother peeling chestnuts for this soup. They buy jarred roasted and peeled chestnuts, and so do I. One 400 gr jar is exactly what you need for this recipe, and you’ll find them in French supermarkets from October right through to Christmas, usually near all other festive treats.
That way, the soup is ready in about half an hour. Luxury dinner, very little effort, and nobody needs to know!

Where chestnut soup comes from
For a very long time, chestnuts weren’t a treat in France at all. In the hilly parts of the country where wheat struggled to grow, like the Cévennes, the Ardèche, the Limousin and Corsica, people lived on them, and the chestnut tree was even called l’arbre à pain, the bread tree. I’ve told the whole story in my article about French chestnuts, but the short version is that chestnuts got whole villages through the winter, and soup was one of the main ways they were eaten.
These days they’ve become much more of a festive ingredient. Think marrons glacés, chestnut cream, Christmas stuffing, and this chestnut velouté. Velouté comes from velours, which means velvet in French, and that’s exactly the texture you’re going for: completely smooth and creamy, even before you add any cream.
And honestly, the fact that you can buy chestnuts in a jar is the reason so many French people make this soup at home. From October onwards, every supermarket has shelves of them. And no, I don’t think anyone would call it cheating.
Ingredients
- Chestnuts — roasted chestnuts in a jar or vacuum pack, already peeled. You’ll see them labelled marrons or châtaignes, and either is fine. Drain them if they come in liquid.
- Onion — cooked slowly in butter, it’s what gives the soup its savoury base.
- Butter — you can use olive oil, but butter is softer and rounder, and I think it suits chestnuts better.
- Vegetable stock — Store-bought or homemade stock.
- Cream — single cream or liquid crème fraîche, added at the end. Not too much, just enough to make it silky without covering the chestnut flavour.
- Salt and pepper — at the end, once you’ve tasted it, because stock can already be quite salty.
How to make chestnut soup
1. Take it slowly with the onion
Cook the onion gently in the butter until it’s soft and see-through, but not golden. If it browns, the soup can taste a bit bitter and won’t have that lovely pale colour.
2. Simmer until the chestnuts are really soft
Add the chestnuts and stock, keeping a few chestnuts aside for the top. Let everything simmer until the chestnuts fall apart when you press them with a spoon. If they’re still firm, the soup will be grainy however long you blend it.
3. Blend, and then blend a bit more
This is what makes it velvety. Blend until smooth, then give it another minute. A stick blender is perfectly fine, but if you have a jug blender, you’ll get an even silkier chestnut velouté.
4. Finish it to your taste
Stir in the cream, taste, and season. Chestnuts make soup thick very quickly, so add a little hot stock or water if you need to. You want it to coat the back of a spoon, not be thick enough to stand a spoon up in.
Tools for this recipe
Check out my favorite kitchen essentials and cookware!
- Use a large heavy-based saucepan or cocotte so the onion can soften gently without catching on the bottom.
- Use a hand blender to blend the soup right in the pan, which means less washing up.
- Use a ladle to serve, and to add stock little by little when you’re adjusting the thickness.
Tips for success
- Keep the onion pale: soft and see-through is what you want. Colour makes the soup bitter.
- Make sure the chestnuts are very soft: they should crush easily with a spoon before you blend.
- Blend longer than you think: that extra minute really does make a difference.
- Adjust the thickness at the end: chestnuts keep thickening as the soup cooks and cools, so add liquid a little at a time.
- Season last: taste first, as some stocks are already salty.
How to store it
- In the fridge: it keeps for up to 3 days in an airtight container. It will thicken, so add a splash of water when you reheat it.
- In the freezer: it freezes well for up to 3 months, ideally before you add the cream. Stir the cream in once it’s reheated.
- Reheating: warm it gently in a saucepan, stirring often, without letting it boil.

Variations
- With toasted hazelnuts: a few chopped toasted hazelnuts on top add a nice crunch.
- With mushrooms: sliced mushrooms fried in butter on top go beautifully with chestnuts.
- With truffle oil: just a few drops before serving, if you want to make it a bit fancy for Christmas.
- With celery: cook a stick of celery with the onion for a fresher, more savoury flavour.
- With milk: swap a third of the stock for milk for an even creamier, gentler soup.
FAQ
Can I use chestnuts in soup straight from the jar?
Yes. They’re already cooked and peeled, so they can go straight into the pan. It’s what most French home cooks use for chestnut soup.
What’s the difference between a chestnut soup and a chestnut velouté?
Not much. A velouté is a soup blended until completely smooth and velvety, usually with a bit of cream at the end. In France, chestnut soup is almost always made like that.
Can I use fresh chestnuts instead?
You can, but you’ll have to score, cook and peel them first, which takes quite a while. Jarred or frozen cooked chestnuts give you very good result for much less work.
What’s the difference between châtaignes and marrons?
Technically, a marron has one big nut inside its spiky shell, while a châtaigne usually has two or three. In the kitchen, though, people use both words for the same thing, and both work in this soup.
What goes well with chestnut soup?
Crusty bread, croutons, sautéed mushrooms or toasted hazelnuts. And if you’re looking for chestnut recipes, soup is the easiest place to start, but they’re also lovely roasted with Brussels sprouts or in a stuffing.
Can I make chestnut soup ahead for Christmas?
Yes. Make it a day or two before, or freeze it without the cream. Reheat it gently and stir in the cream just before serving.

Ingredients
- 25 gr unsalted butter
- 1 onion finely chopped
- 400 gr chestnuts cooked or roasted
- 750 ml vegetable stock
- 100 ml Double cream
- ½ tsp salt
- 2 pinch black pepper freshly ground
Instructions
1. Soften the onion
- Melt the butter in a large saucepan over a medium heat. Add the onion and cook gently for 5 minutes, stirring, until soft and translucent but not coloured.
2. Add the chestnuts and stock
- Set aside 3 or 4 chestnuts for serving. Add the rest to the pan, pour in the hot stock and bring to the boil.
3. Simmer
- Lower the heat and simmer for 20 minutes, until the chestnuts are very soft and break up easily with a spoon.
4. Blend
- Take the pan off the heat and blend with a stick blender until completely smooth.
5. Finish and serve
- Stir in the cream and season with salt and pepper. If the soup is too thick, add a little hot stock or water. Serve topped with the reserved chestnuts, crumbled, and the chives.
Notes
- Chestnuts thicken the soup a lot, so adjust the consistency at the end.
- Frozen cooked chestnuts work too. Just simmer them a little longer.
- Keeps 3 days in the fridge, or 3 months in the freezer without the cream.
