Sunchokes, native to North America, are knotted root vegetables that belong to the sunflower plant family and are in season from late fall through early spring. The root or tuber part of the flowering plant has thin papery skin with a creamy white interior. They are similar to potatoes in their taste and culinary preparations.

These have a mildly sweet, intense nutty flavor akin to water chestnuts, jicama, or hazelnuts. They offer a crunchy bite when eaten raw and render a smooth creamy texture when boiled or roasted.
Angela, who runs a farming vlog on YouTube, shares her experience of taste-testing sunchokes with her two daughters. “I feel like the texture is more like a cooked carrot and the flavor is potato-y (i),” she says. She adds they are not as starchy, fluffy, or flaky as a potato and make for a great food base that can be enhanced with other flavorful ingredients.

Health Benefits Of Sunchokes
Sunchokes are beneficial to our overall health in a few key ways. Some of them are:
- May Act As A Prebiotic
Sunchokes are rich in inulin, which acts as a prebiotic and helps reduce inflammation and improves your metabolism and immunity. It is a polysaccharidei XA type of carbohydrate found in food that promotes the growth of healthy gut bacteria and maintains gut health. , which, unlike sugar, doesn’t get absorbed by the intestine and proceeds to get fermented, stimulating the growth of beneficial bacteria such as bifidobacterium (2), (3).
- May Be Used As A Diet Alternative For People With Diabetes
![Those with diabetes may consume sunchokes as a diet alternative](https://cdn2.stylecraze.com/wp-content/uploads/2021/12/May-Be-Used-As-A-Diet-Alternative-For-People-With-Diabetes.jpg)
Sunchokes contain inulin, a carbohydrate that doesn’t get converted into simple sugars and hence helps keep the blood sugar levels in check (4). Sunchokes can be easily substituted for potatoes in most dishes. Other than adding their mildly sweet flavor, sunchokes can help make these dishes better by removing the starch component. This makes it a good food alternative for people with diabetes or with a risk of developing it. The Glycemic Indexi XA rating system for carbohydrate-rich foods that denotes how quickly the food may affect the blood sugar levels. of sunchokes is low, which makes it a good food choice for those with diabetes. They don’t cause blood sugar levels to spike. They also may help prevent fatty liver.
- May Help Lower Cholesterol
Along with keeping your glucose levels in check, the inulin content in sunchokes might also help lower your cholesterol levels. Animal studies have shown that oral administration of sunchokes inulin helps improve the serum levels of triglyceridesi XA type of fat in the blood that stores unused calories and may increase the risk of heart conditions. , total cholesterol, and LDL cholesterol in hyperglycemic rats (5), (6). Though more research is warranted to establish the same for humans, this is a promising prospect indeed.
- May Be Used As A Wheat Substitute
Sunchoke flour can be used in place of wheat and other grains for people allergic to them. It may make for a suitable alternative to wheat flour in a gluten-free diet.
May Improve Bone Health
Sunchoke leaves have a long history in traditional medicine, where they have been used to treat bone fractures, skin wounds, swelling, and pain. They contain several medicinal compounds in the aerial parts of the plant (7). Sunchoke is also proven to help in preventing calcium loss, which can be beneficial in improving bone health. A study conducted on rats found that consuming sunchoke sorbet resulted in improved calcium content and bone strength. The sunchoke sorbet positively influenced the thickness, area, and mineral content of the lower part of the femur (8). Therefore, consuming sunchoke may help improve bone health and prevent bone-related issues.

- Selection
When it comes to choosing the best sunchokes, look for ones that are firm and clear-skinned without any soft spots or blemishes. Avoid the ones with wrinkled skin, green blotches, or sprouts. Large sunchoke tubers with minimal bumps or knobs are easier to work with and are more ideal for roasting. Larger ones also help you get uniform slices when you cut them.
- Storage
Sunchokes, like any other root vegetables, do well when stored in a well-ventilated, cool, and dry place away from direct sunlight. They can also be wrapped in paper towels or sealed in ziplock bags and stored inside the produce drawer of the fridge. Raw sunchokes can easily last for a minimum of 3-4 weeks. They should be handled with care as they have thin skin and tend to bruise easily. Be careful not to wash them until you are ready to use them as the thin skin might get infected by mold easily.
Once washed and sliced, they can be stored in a sealed container in the fridge for a few weeks. Cooked sunchokes can be kept in the fridge but should be consumed within 2 days. Canning or freezing sunchokes is not advisable as it might lead to a change in color, taste, or texture.

How To Cook Sunchokes
Sunchokes can be had raw, boiled, or cooked into a variety of preparations. They are one of those versatile vegetables that can be easily included in your diet. There are a few things to keep in mind for the proper handling of sunchokes.
- Sunchokes, being root tubers, tend to be soiled, with dirt lodged in the eyes and crevices of the bumps and knots. Remember to scrub them off clean under running water before consuming them raw or cooked.
- Sunchokes, just like apples and potatoes, tend to oxidize and change color when exposed to air. To prevent that, you can toss them with lemon juice before cooking.
- Peeling them can be tedious and is not required as the skin is thin and edible. Moreover, it’s easier to boil or blanch them first and then peel off the skin rather than peeling them raw.
Going further, let’s have a look at some of the common ways to relish sunchokes.
Raw
Sunchokes, like carrots or turnips, can be eaten raw. They have a nice crunch and nutty flavor to them. Once you wash and scrub them clean, you can then grate or thinly slice them to make for a crispy salad topper. You can also have them with a dip or hummus. You can leave the skin on if you want.
Roasted – Roasting sunchokes with their peel on renders a sweet, caramelized crunch that goes well as any succulent main dish.
- Clean the sunchoke tubers well.
- Drizzle a little oil, and season with salt, pepper, and thyme.
- Roast for about 35 minutes at 425°F.
Mashed – Well if you are a fan of mashed potatoes, chances are you would like the starch-free sweet option of sunchokes even better.
- Boil the sunchokes until they get soft, for about 15 minutes.
- Peel and mash the tubers.
- Add a little garlic, butter, or oil according to your preference.

- Cut the sunchokes into thin slices.
