Preheat your oven to 375°F (190°C).
In a mixing bowl, combine flour, sugar, and salt. Add cold butter and mix until the mixture resembles coarse crumbs.
Gradually add ice water, mixing just until the dough comes together. Form the dough into a disk, wrap in plastic wrap, and refrigerate for at least 30 minutes.
In another bowl, combine blueberries, sugar, cornstarch, lemon zest, and lemon juice. Set aside.
Roll out the dough on a floured surface to about ⅛-inch thickness. Transfer to a baking sheet.
Place the blueberry mixture in the center of the dough, leaving a 2-inch border. Fold the edges of the dough over the filling, pleating as necessary.
Bake for 40 minutes, or until the crust is golden and the filling is bubbly. Let cool before serving.
