Swiss chard and potato crostata
1 1/2 pounds Swiss chard, including stems
1 1/2 pounds boiling potatoes
1 cup heavy cream
3 tablespoons extra-virgin olive oil
2 teaspoons salt
2 cups grated low-moisture mozzarella
1 cup freshly grated Grana Padano
So that’s the ingredients list, now for the actual making of the dish
Bring a large pot of salted water to a boil. Cut the leaves from the stems of the chard and cut into 1-inch strips. Cut the stems into 1/2-inch pieces and keep separate. When the water boils, add the stems and boil for 10 minutes, then add the leaves and boil until both are tender, about 15 minutes more. Drain, let cool, then squeeze in your hands until most of the water is out. Chop and set aside.
Meanwhile, put the potatoes in another pot with water to cover and simmer until tender enough to pierce with a fork, about 30 minutes. Drain. When they are cool enough to handle, return the potatoes to the pot and mash, adding the cream and olive oil. Add the chopped Swiss chard and mix well. Beat the eggs and salt together and mix into the potato-chard mixture. Fold in the mozzarella and Grana Padano and set aside.
Heat the oven to 375 degrees. On a floured surface, roll the dough to fit an 18-by-13-inch rimmed baking sheet with about 3 inches extra on all sides, trimming if necessary. Butter the pan. Fit the dough onto the sheet pan, with the extra dough hanging off the sides, and spread the filling evenly over the dough. Fold the overlap of the dough over to form a 2-inch crust around the pan over the filling, leaving the center without crust. Bake until the filling is set and the crust is golden, 40 to 45 minutes. Cool on a rack. Serve slightly warm or at room temperature.
