Shining a light on sunchokes

Like many tubers, sunchokes look a little strange. But when it comes to food, looks often can be deceiving.

"What is that?" This is what someone is sure to ask you at the checkout counter when you load your Jerusalem Artichoke, better known as a sunchoke, on the conveyor. You'll proudly do a little promotional pitch for the vegetable. "You should try them. They're delicious! Like a cross between an artichoke heart and a potato."

Like many tubers, sunchokes look a little strange. But when it comes to food, looks often can be deceiving. A sunchoke is the tasty, knobby root of a sunflower. Until recently, this native of North America was more popular in Europe than in the United States.

The sunchoke is a hardy perennial that can grow in a variety of conditions, and is not frost tender. With water shortages and the growing cost of agriculture, farmers were looking for ecologically sustainable crops, and the sunchoke fit their needs. Sunchokes now are being grown both commercially and by home gardeners. Many small organic farms also are successfully growing sunchokes, so look for them at farm stands and farmers markets (they resemble a ginger root). The crop does have its downside: It has a tendency to grow wild, and can be invasive; presenting challenges for farmers and backyard gardeners alike.

As a healthy addition to our diet, sunchokes are a low-glycemic food, and possess a significant amount of protein and very little starch. They also are rich in inulin, a natural fructose type of carbohydrate. Inulin is thought to be better tolerated by those with type 2 diabetes.

When shopping for sunchokes, look for firm, brown-colored tubers. If they're beginning to darken, they're not fresh. After you get them home, store in paper towels in a plastic bag in the refrigerator for up to two weeks. Don't wash your sunchokes until you're ready to use them, as moisture can lead to spoiling. Sunchokes have a thin skin and don't need to be peeled.

Sunchokes are extremely versatile. You can use them in the same way you typically use a potato. They have a crunchy texture and are delicious raw. When roasted, their nutty flavor comes out. Steamed sunchokes can stand alone or mixed with other vegetables, used in a gratin or to make a delicious soup. If you're using sunchokes in a creamed soup or puree and want to remove the peel for presentation color, pass them through a food mill or a fine mesh strainer.

This recipe for sunchoke chips with Parmesan and parsley is a delicious alternative to potato chips.


2 pounds unpeeled sunchokes (also called Jerusalem artichokes), scrubbed

Vegetable oil (for frying)

1 1/2 teaspoon salt

1/2 cup grated Parmesan

1 1/2 teaspoons minced fresh parsley

  1. Fill a large bowl with cold water. Slice sunchokes into thin rounds (about 1/16 inch thick), immediately dropping into bowl of water to prevent browning. Rinse and drain three times to remove some of the starch for a crisper chip. Pat dry with paper towels.

  2. Pour enough oil into large deep skillet to reach depth of 1/2 inch. Submerge bulb of deep-fry thermometer into oil; lean top of thermometer against skillet rim. Heat oil to 375 F. Mix salt, Parmesan and parsley together in small bowl, blending well, and set aside.

  3. Working in batches, fry sunchoke slices until golden brown, 3 to 4 minutes, stirring occasionally. Using a skimmer, transfer chips to a wire rack placed over a paper-lined baking pan to drain. While chips are hot, sprinkle with the Parmesan and salt mixture. The chips won't be crispy immediately out of the fryer, so wait a few minutes for them to crisp up. Mound chips in bowl and serve. Serves eight.

To bake the chips:

  1. Preheat oven to 400 F. Line two baking sheets with foil and lightly grease with cooking-oil spray. Place slices in a single layer on the two sheets. Spray each slice with oil, then sprinkle salt on top.

  2. Bake for 10 to 15 minutes. If they aren't golden brown and crisp, bake in 3 to 5 minute increments until done. Sprinkle with topping of your choice.

Alternate toppings:

For protein boost and cheese flavor: sprinkle chips with 1/2 cup nutritional yeast

For spicy flavor: sprinkle with 1-tablespoon chili powder and 1/4 teaspoon cayenne pepper

For salt and vinegar chips: soak sunchokes in vinegar for 2 hours before frying. Drain and pat completely dry. Fry or bake as directed, and sprinkle with salt.
