Despite the name, this leafy green isn’t actually Swiss. It’s Sicilian, or so the plant sages say. It’s also one of the healthiest foods in the world, housing a slew of vitamins, minerals, and antioxidants that chef Nick Marckwald of Hen of the Woods, a pop-up dinner series, likes to incorporate in his summertime dishes when the chard is bountiful, affordable, and at the peak of freshness. Its mild taste, versatility, and flavor fusion with sunchokes makes for a crunchy, savory gratin that’s sure to please health- and flavor-conscious eaters alike.
Recipe: Swiss Chard and Sunchoke Gratin For the gratin2 bunches Swiss chard1 lb sunchokes, peeled and diced2 shallots, sliced3 thyme sprigs2 Tbsp olive oil¾ cup dry white wine3 oz butter, chilled and cut into ½ inch cubes½ tsp black pepper, freshly ground1 pinch nutmegsalt to taste
In a small sauté pot over low heat, sweat shallots and thyme in olive oil for 5 minutes. Deglaze with wine and reduce by half. Add sunchokes and cover with 1 inch of water. Bring to a low boil and cook for approximately 20 minutes, until fork tender.
Using a slotted spoon, transfer the sunchokes into a blender and reserve the cooking liquid. Add about ¼ cup of the cooking liquid and process on low speed. Switch to high speed, adding more liquid as necessary to create a vortex. Add the cold butter, a piece at a time. Blend until completely emulsified, then season with salt, pepper, and nutmeg to taste. Set aside.
Chop the chard leaves into bite-sized pieces, and finely slice the stems. Blanch the leaves for 30 seconds and the stems for one minute, then shock both in an ice water bath. When cool, remove and drain completely.
For the topping1 cup panko bread crumbs10 thyme sprigs½ cup parmesan, freshly grated2 oz butter, melted2 tsp kosher salt Combine the panko, thyme, parmesan, salt, and butter in a large sauté pan and toast until lightly browned.
Preheat oven to 350 degrees. To assemble, combine chard leaves and stems with sunchoke puree. Pour into an 8 x 10 gratin dish and top evenly with bread crumb mixture. Bake for about 20 minutes. Brown topping under broiler and allow to cool slightly before serving.
