Ingredients
1 cup chickpea flour
Kosher salt and freshly ground pepper
1 cup lukewarm water
1/4 cup extra-virgin olive oil
1/2 bunch rainbow Swiss chard (about 8 ounces), stems and leaves separated
1 tablespoon grated Parmesan, preferably on a Microplane
Flaky sea salt, such as Maldon
Preparation
In a bowl, combine chickpea flour and 3/4 teaspoon kosher salt. Slowly whisk in water until a smooth batter with no lumps forms. Whisk in 2 tablespoons oil. Let stand, covered, at room temperature at least 1 hour, or refrigerate up to overnight. Whisk before continuing.
Cut chard stems into 1/2-inch pieces, and leaves into 2-inch pieces. Heat a large skillet over medium-high. Add 1 tablespoon oil and chard stems; cook until stems soften, 3 minutes. Add leaves; cook, tossing occasionally, until wilted, 3 minutes. Season with kosher salt and pepper.
Preheat oven to 450 degrees. Place three 8-inch cast-iron pans in oven for 15 minutes. Remove pans from oven; swirl 1 teaspoon oil into each. Divide batter among pans and top each with one-third of chard mixture. Bake until cooked through and golden brown on edges, about 15 minutes. Sprinkle each with 1 teaspoon cheese. Season with flaky salt and pepper; serve.
