The Jerusalem artichoke, also known as the sunchoke, is a unique and highly nutritious tuber that offers a blend of health benefits and a delicious, nutty flavor profile. While it may not be as well-known as other root vegetables like carrots or beets, its growing popularity among nutritionists, chefs, and health enthusiasts has placed it on the radar as a superfood worth exploring. In this article, we’ll walk you through how to eat Jerusalem artichoke, including tips for preparation, cooking methods, flavor pairings, and where to buy or grow it. Whether you’re a culinary novice or an adventurous food lover, this guide will give you everything you need to make the most of this versatile vegetable.
What Is a Jerusalem Artichoke?
Before diving into how to eat a Jerusalem artichoke, it’s worth understanding exactly what this vegetable is. Despite its name, the Jerusalem artichoke is not related to the globe artichoke or the city of Jerusalem. Its name is thought to be a corruption of the Italian word “girasole,” meaning sunflower, as the plant belongs to the sunflower family (Helianthus tuberosus). It’s grown for its edible tubers rather than its flowers or seeds.
The tubers have a knobby, irregular shape and come in shades of tan, white, red, and purple depending on the variety. While their skin is thin and edible, their texture is crisp when raw and creamy when cooked. They’re prized for their high inulin content, a natural prebiotic fiber that benefits gut health and has a low glycemic index, making them a preferred choice for diabetics and health-conscious individuals.
Jerusalem Artichoke Nutrition Facts
Understanding the nutritional powerhouse behind this tuber can help clarify why incorporating it into your diet can be beneficial. Some key nutritional highlights per 100 grams of raw Jerusalem artichoke include:
- Approximately 73 calories
- 17.4 grams of carbohydrates
- 2 grams of protein
- 1.0 gram of fat
- 1.6 grams of dietary fiber, predominantly inulin
- Rich in potassium, iron, and thiamine (vitamin B1)
- Good source of niacin, phosphorus, and magnesium
The high inulin content is key: it’s a type of fructan that acts as a prebiotic, feeding beneficial gut bacteria. However, it’s worth noting that for some people, raw sunchokes can cause digestive discomfort due to this fermentable fiber — something we’ll discuss later on.
How to Select and Store Jerusalem Artichokes
When incorporating Jerusalem artichokes into your diet, knowing how to choose the best quality tubers and store them correctly is crucial.
How to Choose the Best Jerusalem Artichokes
When shopping for Jerusalem artichokes — often labeled as sunchokes — you want to find tubers that are firm, without bruises, and preferably not wrinkled or soft. Smaller tubers are less fibrous and tend to be more tender than larger, older ones. If the skin is muddy, don’t be alarmed — this is normal and indicates that it’s not been washed, preserving its freshness.
Proper Storage Methods
Jerusalem artichokes can be stored similarly to potatoes. Here are some best practices:
- Store unwashed in a cool, dark, and humid place such as a cellar or refrigerator crisper drawer.
- Place them in a perforated plastic bag to retain moisture while allowing some airflow.
- Stored properly, they will last up to 2–3 weeks in the refrigerator.
If you’re lucky enough to grow your own Jerusalem artichoke, you can even leave them in the ground until you’re ready to use them — they tolerate frost well, making them excellent candidates for fall harvests and winter gardening in temperate climates.
How to Prepare Jerusalem Artichoke for Cooking
Now that you’ve got your sunchokes, you may be wondering about the best way to clean and cut them before cooking.
Cleaning and Peeling
One of the first decisions to make is whether to peel the tubers. The skin is edible, but it can be thick and a bit gritty around the knobby parts. Many people choose to clean the tubers thoroughly using a vegetable brush under running water, removing any visible dirt or debris.
If the skin is particularly coarse or you prefer a smoother mouthfeel in your recipes, you can peel them using a sharp vegetable peeler or paring knife. Just be cautious not to remove too much of the flesh.
Slicing and Dicing
Cutting Jerusalem artichokes for your dish depends largely on the recipe you’re planning. In general:
- Thin slices: best for roasting or frying.
- Dice or cubes: ideal for soups, stews, or gratins.
- Julienne or grated: use in salads or slaws when served raw.
One thing to keep in mind — once cut, the bright white flesh will oxidize quickly and brown similar to an apple. To prevent browning, you can place them in a bowl of water with lemon juice (1 tablespoon of lemon juice per cup of water) while preparing.
Cooking Methods for Jerusalem Artichoke
One of the best parts of learning how to eat Jerusalem artichoke is discovering its versatility in the kitchen. Below are several popular methods you can use to bring out its distinct flavor and texture.

How to Handle the Digestive Effects of Jerusalem Artichoke
One consideration when eating sunchokes is their effect on digestion.
Why It May Cause Bloating or Gas
Because of the high inulin content, raw or excessive consumption of sunchokes can cause bloating and flatulence for some people. This is especially true for those who are not accustomed to fermentable fibers or people with digestive sensitivities such as IBS.
How to Minimize Unwanted Side Effects
Here are a few tactics to reduce digestive discomfort:
- Start with small portions. Begin with a modest serving size and monitor how your body reacts.
- Cook before consumption. Cooking partially breaks down the inulin, making the tubers easier to digest.
- Introduce gradually into your diet. Let your gut microbes adjust over time, possibly reducing initial discomforts.
- Pair with digestive aids. Including herbs like ginger, fennel, or peppermint with your meals may assist digestion.
For those particularly sensitive to FODMAPs, fermented prebiotics may not be suitable in large amounts. For general health benefits, moderation is key.

Can you eat Jerusalem artichoke raw?
Yes, Jerusalem artichoke can be eaten raw, and doing so preserves its natural crispness and nutrient content. When raw, the tuber has a slightly sweet, nutty flavor and a texture similar to that of a pear or water chestnut. To enjoy it raw, peel the skin thoroughly or even soak the slices in lemon water to prevent browning and soften any earthy flavors.
Raw Jerusalem artichokes are excellent added to salads, slaws, or as a crunchy garnish. However, it’s important to note that consuming large quantities raw might lead to digestive discomfort for some people due to the high inulin content, a type of dietary fiber that can cause gas and bloating. Cooking can help break down the inulin and make the vegetable easier on the digestive system.
What are the best ways to cook Jerusalem artichoke?
Jerusalem artichoke is versatile and can be cooked in several ways that highlight its unique earthy and slightly sweet flavor. Roasting, sautéing, and boiling are among the most popular methods. Roasting at 400°F (200°C) until golden brings out caramelized notes, while boiling the tubers allows them to be mashed or pureed into creamy textures akin to potato mash.
Another great cooking method is steaming, which allows the Jerusalem artichoke to retain most of its nutrients without the addition of fats. Sautéing thinly sliced pieces in olive oil or butter until crisp and golden creates a quick side dish or addition to grain bowls. Experimenting with herbs and spices like rosemary, thyme, garlic, and black pepper can further enhance the flavor profile and provide a gourmet experience.
Is it necessary to peel Jerusalem artichoke before cooking?
Peeling Jerusalem artichoke is recommended before cooking or eating due to its rough, knobby skin, which can harbor dirt and have a tough texture. While the skin is edible after thorough washing and cooking, it can be gritty and less appealing compared to the tender, creamy flesh inside. Using a vegetable peeler or paring knife makes the peeling process easier, especially for larger tubers.
However, if you prefer a rustic presentation or are slow-roasting the tubers, you can scrub them clean and cook them with the skin on. In these cases, most people remove the skin before eating. Whether peeled or unpeeled, soaking the tubers briefly in cold water with a bit of vinegar or lemon juice can help prevent oxidation and keep them from turning brown during preparation.
Can you substitute Jerusalem artichoke for potatoes in recipes?
Yes, Jerusalem artichoke can often be substituted for potatoes in many dishes, although its texture and flavor differ slightly. It is particularly well-suited for soups, stews, and even mashed dishes. When making mashed Jerusalem artichoke, you may find the texture slightly grainier, so mixing it with potatoes or adding creamy components like butter or cream can help achieve a smoother consistency.
Keep in mind that Jerusalem artichoke has a naturally sweeter and nuttier flavor compared to potatoes, which can subtly alter the taste of the original recipe. Additionally, because of the inulin content, Jerusalem artichokes don’t hold up as well during high heat frying and may not crisp the same way potatoes do. For best results, try it first in roasted or pureed preparations where its unique flavor profile can stand out.
Are there any health benefits to eating Jerusalem artichoke?
Jerusalem artichoke is packed with nutritional benefits that make it a valuable addition to a healthy diet. It is an excellent source of dietary fiber, particularly inulin, which acts as a prebiotic and supports gut health by stimulating the growth of beneficial bacteria. It also contains essential minerals such as potassium, iron, and magnesium, as well as B vitamins, especially vitamin B1 (thiamine).
In addition, Jerusalem artichoke is low in calories and contains natural sugars that make it a great choice for those looking for a nutrient-dense, energy-rich vegetable. Its low glycemic index means it can be particularly beneficial for people managing blood sugar levels. However, portion control is recommended due to the high inulin content, which can cause digestive discomfort in sensitive individuals.
How should you store Jerusalem artichoke to keep it fresh?
To keep Jerusalem artichokes fresh for an extended period, store them properly in a cool, dark, and humid environment. Ideally, they should be kept in a root cellar or the crisper drawer of a refrigerator, wrapped in a damp paper towel or placed in a plastic bag to retain moisture. This method can preserve freshness for up to two weeks, though the earlier they’re used, the better the flavor and texture.
Avoid washing Jerusalem artichokes before storage, as excess moisture can lead to spoilage. If you have an abundant harvest, consider blanching and freezing cooked or partially cooked slices. Alternatively, you can keep them in a container of water in the fridge for a few days, changing the water daily to maintain freshness and prevent odor absorption from other foods.
What does Jerusalem artichoke taste like?
Jerusalem artichoke offers a unique and somewhat complex flavor profile that is often described as earthy, slightly sweet, and nutty. It’s reminiscent of artichokes (the vegetable from which it gets its name), along with subtle notes similar to potatoes and chestnuts. When raw, the taste has a mild crispness akin to that of water chestnuts with a slightly sweet and floral edge.
When cooked, the natural flavors intensify, and the texture varies depending on the cooking method. Roasting gives it a sweet and caramelized surface, while boiling makes it tender and creamy. This versatile taste makes the Jerusalem artichoke a great option for those looking to explore diverse flavor experiences in root vegetables. It pairs well with garlic, herbs like rosemary and sage, sweeteners like honey or maple syrup, and even acidic elements like lemon or vinegar.
