You’ve probably seen them at the farmer's market looking like a pile of dirty, knobby ginger roots. Maybe you walked right past. Honestly, most people do because they look like a literal nightmare to prep. But these things—Jerusalem artichokes, or sunchokes if you’re fancy—are basically the secret weapon of high-end bistro chefs who want to make something taste like a cross between a potato, a water chestnut, and a sunflower seed.
If you’re looking for a recipe for jerusalem artichoke, you need to ignore the old-school advice. Most older cookbooks tell you to peel them. Don’t do that. It’s a massive waste of time and you lose the best part of the flavor.
The skin is where the earthiness lives. Just scrub them with a stiff brush under cold water. Get into the nooks. If a knob is too gnarly to clean, just snap it off. Once they're clean, we’re going to treat them with some serious heat.
The Science of the Sunchoke (and the "Fartichoke" Problem)
Let’s be real for a second. We have to talk about the gas. There is a reason these things are nicknamed "fartichokes."
Unlike potatoes, which store energy as starch, sunchokes store it as inulin. Inulin is a prebiotic fiber. Your gut bacteria absolutely love it, and when they feast, they produce gas. If you aren't used to high-fiber foods, eating a giant bowl of these could make your evening... interesting.
But there’s a fix. According to Harold McGee in On Food and Cooking, boiling sunchokes in an acid—like lemon juice or vinegar—can help break down some of those complex sugars before they hit your system. Alternatively, start small. Don’t eat a pound of them on your first try.
Slow roasting also helps. The longer they cook, the more that inulin breaks down into fructose. This is why a roasted sunchoke tastes so much sweeter than a boiled one. It’s chemistry you can taste.
The Only Recipe for Jerusalem Artichoke You Actually Need
Forget the purees for a minute. If you want to actually enjoy these, you want texture. You want crispy, salty skins and a middle that’s almost like custard.

What you'll need:
- A pound of sunchokes (pick the smoothest ones you can find).
- Three tablespoons of high-smoke-point oil. Avocado oil is great here.
- Flaky sea salt. Don't use the fine table stuff.
- Four cloves of garlic, smashed but kept in their skins.
- A sprig of rosemary or thyme.
The process:
First, preheat your oven to 425°F (220°C). You need it hot.
Cut the larger tubers in half lengthwise so they have a flat surface. Leave the small ones whole. Toss them in a bowl with the oil and salt until they’re glistening.
Now, here is the pro tip: get a heavy baking sheet and put it in the oven while it preheats. When you dump the sunchokes onto a screaming hot pan, they start searing immediately. Place them cut-side down. You’ll hear a sizzle. That’s the sound of the sugars caramelizing.
Throw the garlic and herbs on top. Roast for about 25 to 30 minutes. You’re looking for a deep, dark brown on the flat sides. If they look burnt, they’re probably just right. Sunchokes can handle a lot of color.
When they come out, they should be soft enough to squash with a fork. Squeeze the roasted garlic out of the skins and toss it back with the chokes.
Beyond the Roast: Other Ways to Play
If roasting feels too simple, you can pivot. Because they have a crisp texture when raw, some chefs like Jeremy Fox (who wrote On Vegetables) suggest shaving them paper-thin on a mandoline.
Toss the raw shavings with lemon, olive oil, and some shaved parmesan. It’s totally different. It’s bright, crunchy, and nutty. It tastes like a sophisticated radish without the spicy bite.

The Pan-Sear Method
If you don't want to turn on the oven, you can treat them like scallops.
- Slice them into 1/2-inch thick rounds.
- Get a cast iron skillet hot with some butter and oil.
- Sear until golden on both sides.
- Add a splash of vegetable stock or water, cover the pan, and let them steam for 5 minutes.
- Remove the lid and let the liquid evaporate until they sizzle again.
This gives you a texture that’s almost creamy. It’s incredible with a bit of lemon zest on top.
Common Mistakes Most People Make
The biggest error is undercooking. A half-cooked sunchoke is sort of crunchy and underwhelming. It needs to be fully softened to unlock that "artichoke" flavor. If you poke it with a knife and there's any resistance, give it another five minutes.
Another mistake? Too much water. If you boil them like potatoes, they can become waterlogged and sad. If you must boil them for a puree, do it in milk or a mix of cream and stock. The fat helps carry the earthy notes and keeps the texture velvety rather than grainy.
Pairing Your Sunchokes
What do you serve this with?
Since they’re quite earthy and rich, they need acidity.
- Hazelnuts and Balsamic: The nuttiness of the hazelnut mimics the flavor of the sunchoke perfectly.
- Salsa Verde: A bright, herb-heavy sauce cuts right through the richness.
- White Fish: They’re a classic side for sea bass or cod.
- Mushrooms: If you want to go full "forest floor" vibes, sauté them with chanterelles.
Selecting and Storing
When you're at the store, look for tubers that feel heavy for their size. If they feel light or spongy, they’re old and will be woody inside. Avoid anything with green spots or lots of sprouts.

Storage is a bit tricky. Unlike regular potatoes, sunchokes don't have a thick, protective skin. They’ll dry out in a cupboard. Keep them in a paper bag in the crisper drawer of your fridge. They’ll last about two weeks there. If they start to get soft, you can revive them in a bowl of ice water for a few minutes, but it's better to just cook them fresh.
The Reality of Jerusalem Artichokes
There is a lot of misinformation out there. No, they aren't from Jerusalem. The name is likely a corruption of the Italian word for sunflower, girasole. And they aren't artichokes, though they are in the same family (Asteraceae).
They are actually native to North America. Native Americans cultivated them long before Europeans arrived. Samuel de Champlain, the French explorer, was the one who thought they tasted like artichokes and sent them back to France, where they became a massive hit.
They’re incredibly easy to grow, too. If you leave one piece in the ground, you’ll have a whole forest of six-foot-tall sunflowers by next August. Just be warned: once you plant them, you have them forever. They are persistent.
Actionable Steps for Your First Batch
If you’re ready to try this recipe for jerusalem artichoke, start here:
- Buy small: Look for the smallest, smoothest tubers to minimize prep time and maximize surface area for crisping.
- Scrub, don't peel: Use a clean scouring pad or a vegetable brush. You want that skin.
- High heat is king: Don't be afraid of a 425°F or even 450°F oven. You want that caramelization.
- Limit your portion: Eat about a half-cup the first time to see how your stomach handles the inulin.
- Finish with acid: Always hit them with a squeeze of lemon or a drop of sherry vinegar right before serving to wake up the flavors.
Once you nail the roast, try mashing the leftovers into your morning potato hash. The sweetness they add is a game changer for breakfast.
