Jerusalem artichoke soup is a perfect way to get to know a less-then-common veggie. Widely used in France to make some of the creamiest, velvetiest soups possible, Jerusalem artichokes are combined here with cream, onion, garlic, butter, and thyme. Add a drizzle of truffle oil and a sprinkle of crunchy Jerusalem artichoke chips and you’ll be a fan, too.

Jerusalem artichokes are not generally appreciated. This may be due to their knobbly ugly shape, which makes them difficult to peel. We love their sweet nutty flavor, however, and their wonderful velvety texture when blended.– Catherine & John Pawson
WHAT ARE JERUSALEM ARTICHOKES?
Also called sunchokes, Jerusalem artichokes, are a species of sunflower that was originally grown across North America before being sent to Europe. Their use in North America has fallen off somewhat, meaning that most of us aren’t that familiar with them.
It’s a tuber–which is pretty apparent when you lay eyes on these knobbly little babes–that’s eaten as a root vegetable. They can be prepared in countless ways–raw, baked, puréed, and on and on. They take on a sweet and nutty taste when cooked, especially when roasted.

Jerusalem Artichoke Soup
Ingredients
For the soup
- 2 tablespoons (1 oz) unsalted butter
- 2 tablespoons olive oil
- 1 large (7 oz) onion finely chopped
- 2 cloves garlic finely chopped
- 1 sprig thyme leaves picked, plus extra for sprinkling
- 2 1/4 pounds Jerusalem artichokes scrubbed and peeled, if desired, cut into equal sized chunks
- 3 cups store-bought or homemade vegetable broth
- 1 cup whole milk
- 1/3 cup heavy cream
- Sea salt and freshly ground black pepper
- Bread to serve (optional)
- A drizzle of truffle oil to serve (optional)
For the artichoke chips
- 2 (3 1/2 oz) Jerusalem artichokes scrubbed
- 1 to 2 tablespoons (1/2 to 1 ounce) unsalted butter
Directions
Make the soup
- In a large, heavy saucepan over medium heat, melt butter and olive oil. Add onion, garlic, and thyme leaves and cook until softened but not colored, 5 to 10 minutes.
- Chop the Jerusalem artichokes into bite-sized pieces. Add them to the saucepan and cook until just tender, 10 to 15 minutes. Pour in the stock and bring to a boil, reduce heat and simmer for 20 minutes more.
Make the artichoke chips
- Using a mandoline or vegetable peeler, finely slice the two unpeeled artichokes into 1/8-inch (3 mm) thick slices.
- In a medium skillet over medium heat, melt the butter, then add the artichoke slices and fry, tossing until they're golden and crispy, 4 to 5 minutes.
- Remove soup from heat, add milk and cream, and use an immersion blender to purée until smooth. Alternatively, you can carefully pour the soup into a regular blender and blitz until smooth. Season to taste with salt and pepper.
- Divvy soup among warm bowls, top with a few artichoke crisps and a sprinkle of thyme leaves. Serve with bread on the side, if desired. A drizzle of truffle oil will not go amiss.

Recipe Testers’ Reviews
I love the nuttiness of Jerusalem artichokes. Usually, I just scrub them and roughly chop and roast them. They tend to be expensive and thus underused. I also feel that by having “artichoke” in the name they’re compared to the thistle variety and obviously don’t measure up in looks. We’re so vain…
This Jerusalem artichoke soup recipe really appealed to me for the creaminess and for the chip garnish. It didn’t disappoint one little bit! Each spoonful was velvety and flavourful with an almost understated richness.
The only thing I’d change would be to use clarified butter or ghee to fry the chips. I had some uneven cooking due to burnt butter. Luckily, the number of chips was sufficient for the 6 bowls despite a few dark ones being discarded.
We each enjoyed a bowl of this delectable Jerusalem artichoke soup as a first course. The chip garnish and the drizzle of truffle oil are indispensable.
Let me start by saying that I had never tried Jerusalem artichokes before making this soup and I will never look back. I served it to four self-proclaimed foodies and all loved it.
This Jerusalem artichoke soup is a substantial soup with a wonderful nutty taste. The thyme is essential so don’t skimp on it. I served it with the artichoke crisps and then passed around additional crisps for people to add to their soup as they went along.
I also passed the white truffle oil. I tried it both with and without the truffle oil, both were wonderful, and my eaters raved about the soup both ways. I didn’t purée my soup until it was completely smooth but left it with a bit of texture because I tend to like textured soup, but I think it would be good either way.

Made this as part of a first course – really lovely soup. Did a few things differently:
1a. Caramelized onions a bit before adding sunchokes. I can’t definitively say if it made a big difference, but I’d like to think I can taste the added sweetness.
1b. This meant that the onion mixture started sticking to the pan a bit, so I deglazed with a couple tablespoons of dry vermouth.
2. We used chicken instead of vegetable stock, as we didn’t have any on hand.
3. We wanted a thicker soup, so I just did 1/3 cup cream and 1/3 cup milk – I like the thickness like this.
4. We also wanted it to truly be a purée. I didn’t want to lose the flavor added by the skins, so I left them on. But when puréeing, I couldn’t get it to a perfectly smooth place. So I strained all the skin out.
5. No truffle oil on hand, so seasoned with black truffle salt instead.
Thinking of serving this with some pan-seared scallops, will circle back on whether it’s truly a good fit 🙂
That sounds incredible, Lynn. Thank you so much for taking the time to share your experience. We’re delighted that you enjoyed it and look forward to hearing about how it paired with the scallops.
Thanks Angie! We might not end up serving them with the scallops (though I still believe it would be a lovely pairing) — I think I should have cooked them a bit longer than I did, they were still quite inulin-y. So, a word of caution to others wishing to try this recipe: maybe do a bit of research on ways to get the inulin out of sunchokes, or just cook them for awhile, even after they’re tender enough to blend? It’s still a really, really beautiful/delicious/wonderful soup, just don’t want to plague dinner guests with digestive troubles.
I hear you, Lynn. And some folks are more sensitive than others!
How about a picture of a Jerusalem artichoke?
Doy!! Why didn’t we think of that? Thank you for the nudge. I added a photo so it’ll be easy to recognize them when you’re at the supermarket or farmstand.
You have to be careful with sunchokes. Probably best not to serve to company.
Steve, do you mean because of the gas and bloating? That’s due to inulin, the carbohydrate in raw Jerusalem artichokes (aka fartichokes!). This recipe calls for them to be cooked fully, so less trouble. But your point is well taken.
