Double “Artichoke” Gratin

By Cheryl Forberg, RD
Image of Sunchokes
The Jerusalem artichoke (also called sunchoke or sunroot) is a type of sunflower which is considered a root vegetable. It is not actually an artichoke at all, but is so named because it’s flavor is somewhat similar to Globe artichokes. The sunchokes’ tubers are elongated and uneven resembling gingerroot with a crisp texture when raw. Once cut, it oxidizes (browns) quickly.

Initially a food source for Native Americans, sunchokes have had a resurgence in popularity in the U.S. in the last 25 years. Though predominantly composed of carbohydrates (with little protein and no fat), the sunchoke is actually low in starch, but high in a compound called inulin which is a form of fructose and responsible for the chokes’ sweet flavor. Inulin also helps to promote blood sugar control.

The tasty tubers are sometimes used as a substitute for potatoes and are delicious when simply roasted with oil, salt and pepper. They can also be consumed raw in a salad, in which case they’re probably better off peeled. That’s because much of the inulin they contain is found in the skin and it cannot be broken down by the human digestive system. Instead, it’s broken down by bacteria in the colon. This can cause flatulence, so if you haven’t tried them before, you might want to have a small serving the first time.

My dish is inspired by a Martha Stewart gratin recipe. Martha used potatoes with her sunchokes, but I chose to use artichoke hearts instead. Feel free to experiment with different kinds of cheese. Smoked gouda would be very good.

Drain the sunchokes and transfer to a 2-quart saucepan. Add milk just to cover; it should be about 3 cups.

Bring to a boil and immediately reduce heat to simmer. Stir occasionally so the milk doesn’t burn. Simmer for 5 minutes. Remove from heat, drain artichokes, reserving the milk.

Transfer vegetable mixture to a shallow 2-quart baking dish, patting down veggies to remove any large air pockets.

Pour about 1 cup of the remaining milk over the vegetables until it just reaches the top of the vegetables. Add more milk if needed. (Discard any extra milk).

Cover baking pan with foil and bake in preheated oven for 45 minutes. Remove from oven and increase heat to 450 degrees.
