Before cooking Jerusalem artichokes, scrub their knobby skins thoroughly to remove any lingering soil. If you are wondering how to cook Jerusalem artichokes, you have come to the right place. These knobby tubers, also called sunchokes, have a nutty, sweet flavor that works in soups, roasts, and even raw salads. They are easy to prepare once you know a few simple tricks.
Jerusalem artichokes are not actually artichokes. They are the root of a sunflower variety. Their skin is thin and edible, but you must clean it well because dirt hides in the bumps. You can peel them if you want, but it is not necessary. The flesh turns brown quickly after cutting, so drop them in lemon water right away.
What Are Jerusalem Artichokes
These tubers look a bit like ginger root. They have a crisp texture and a flavor similar to water chestnuts or potatoes with a hint of sunflower seed. They are packed with fiber and inulin, a prebiotic that supports gut health. Some people get gas from them at first, so start with small portions.
You can find them in most grocery stores from fall through spring. Look for firm, unblemished tubers. Avoid any that are soft or sprouting. Store them in a paper bag in the fridge for up to two weeks.
Why You Should Cook Them
Raw Jerusalem artichokes are crunchy and good in salads. But cooking softens their texture and brings out their sweetness. Roasting caramelizes their natural sugars. Boiling makes them tender for mashing or pureeing. Sautéing gives them a golden crust.
One important note: do not cook them in aluminum pots. The tubers contain compounds that react with aluminum, turning them an unappetizing gray color. Use stainless steel, enamel, or glass instead.
How To Cook Jerusalem Artichokes
Now let us get into the actual methods. Each technique gives a different result. Choose based on what you want to make.
Roasting Jerusalem Artichokes
Roasting is the most popular method. It brings out a nutty, almost buttery flavor. Here is how to do it.
- Preheat your oven to 400°F (200°C).
- Scrub the tubers well under running water. Cut off any dark spots or roots.
- Slice them into even pieces, about 1/2 inch thick. Uniform size ensures even cooking.
- Toss the pieces with olive oil, salt, and pepper. Add garlic cloves or fresh rosemary if you like.
- Spread them in a single layer on a baking sheet. Do not overcrowd.
- Roast for 25 to 35 minutes, flipping halfway through. They should be golden brown and tender when pierced with a fork.
Roasted sunchokes are great as a side dish. You can also toss them with balsamic vinegar or lemon juice after cooking for extra zing.
Boiling Jerusalem Artichokes
Boiling is quick and simple. It works well if you plan to mash them or use them in soups.
- Scrub and slice the tubers into chunks.
- Place them in a pot and cover with cold water. Add a pinch of salt.
- Bring to a boil, then reduce to a simmer.
- Cook for 10 to 15 minutes, until fork-tender.
- Drain and use as desired.
For mashed sunchokes, boil them until very soft, then mash with butter, cream, and salt. They are smoother than potato mash but have a similar consistency. You can also puree them for a silky soup base.
Sautéing Jerusalem Artichokes
Sautéing gives you a crispy exterior and a tender interior. It is a fast method for weeknight dinners.
- Scrub and slice the tubers thinly, about 1/4 inch thick.
- Heat a skillet over medium-high heat. Add butter or olive oil.
- Add the slices in a single layer. Do not stir too much at first.
- Cook for 4 to 5 minutes per side, until golden and crisp.
- Season with salt, pepper, and fresh herbs like thyme or parsley.
These sautéed slices make a great topping for salads or a simple side for fish or chicken. You can also add a splash of white wine or chicken broth at the end for a quick pan sauce.
Steaming Jerusalem Artichokes
Steaming preserves more nutrients than boiling. It also keeps the texture firmer.
- Scrub and slice the tubers into even pieces.
- Place them in a steamer basket over boiling water.
- Cover and steam for 10 to 15 minutes, until tender.
- Season with salt, pepper, and a drizzle of olive oil.
Steamed sunchokes are mild and slightly sweet. They work well in cold salads or as a base for a vinaigrette.
Frying Jerusalem Artichokes
Frying turns them into crispy chips or fritters. This is a treat, not an everyday method.
- Scrub and slice the tubers very thin, using a mandoline if you have one.
- Soak the slices in cold water for 30 minutes to remove excess starch.
- Drain and pat dry thoroughly.
- Heat oil to 350°F (175°C) in a deep pot.
- Fry in small batches for 2 to 3 minutes, until golden and crisp.
- Drain on paper towels and season immediately with salt.
These chips are addictive. Serve them with dips or as a garnish for soups.
Tips For Preparing Jerusalem Artichokes
Before you start cooking, there are a few things to keep in mind. These tips will save you time and frustration.
Cleaning Is Key
The knobby skin traps dirt. Use a stiff brush under running water. If you see deep crevices, cut them out. You can also soak the tubers in water for a few minutes to loosen soil.
Prevent Browning
Like potatoes and apples, Jerusalem artichokes oxidize when cut. Drop them into a bowl of water with lemon juice or vinegar. This keeps them white until you are ready to cook.
Do Not Overcook
These tubers go from tender to mushy quickly. Check them a few minutes before the recommended time. Overcooked sunchokes lose their texture and become watery.
Pair With Strong Flavors
Jerusalem artichokes have a mild taste. They pair well with garlic, rosemary, thyme, lemon, bacon, or Parmesan. They also absorb flavors from broth or wine.
Recipes Using Jerusalem Artichokes
Here are three simple recipes to try. Each uses a different cooking method.
Roasted Sunchokes With Garlic And Rosemary
This is a classic side dish. It goes well with roasted chicken or pork.

Creamy Jerusalem Artichoke Soup
This soup is smooth and comforting. It is perfect for cold days.

Raw Sunchoke Salad With Lemon Vinaigrette
This salad is crunchy and refreshing. It is a great way to enjoy them raw.

Common Mistakes To Avoid
Even experienced cooks make errors with Jerusalem artichokes. Here are the most common ones.
Skipping The Scrub
Dirt hides in the bumps. If you do not scrub thoroughly, you will bite into grit. Use a brush and rinse well.
Using Aluminum Cookware
As mentioned, aluminum turns them gray. Stick to stainless steel or nonstick pans.
Overcrowding The Pan
When roasting or sautéing, too many pieces in the pan causes steaming instead of browning. Give them space.
Not Soaking After Cutting
If you cut them ahead of time and do not soak them, they turn brown. Lemon water is your friend.
