Do you need an easy, easy summer dessert? Whether it be for the Fourth of July, a backyard BBQ, a summer potluck… or simply… because. This Summer Blueberry Crostata is one of the simplest “pies” you’ll ever make.
Preheat oven to 400°F. Line baking sheet with parchment. Set aside.
Make the Filling: Stir together blueberries, cornstarch, zest, juice, sugar, and salt in a large bowl until combined.
Transfer dough to parchment-lined baking sheet. Spread the filling in the center of the dough, leaving a 2-inch border. Fold the border over the filling, pleating the edges as you go.
Whisk egg and water together. Brush the egg wash over the edges of the dough and sprinkle with coarse sugar.
Bake in a 400°F oven for 30-35 minutes, or until golden brown. Remove from the oven and let stand for 5 minutes. Cut into wedges and serve hot, warm or at room temperature.
