Instructions
Whisk together the flour, sugar, and salt in a large bowl. Add cold cubed butter and use a pastry cutter or two forks to work it in until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
Drizzle in ice-cold water one tablespoon at a time, tossing with a fork until the dough just holds together when pressed. Turn out onto a lightly floured surface, shape into a 1-inch-thick disk, wrap in plastic wrap, and refrigerate for at least 1 hour.
Rinse and pat the blueberries completely dry, then combine them with the sugar, cornstarch, lemon juice, lemon zest, and vanilla extract in a medium bowl. Toss gently until evenly coated and set aside.
Remove the chilled dough from the refrigerator and let it rest 5 minutes. On a lightly floured sheet of parchment paper, roll the dough into a rough 12-inch circle, then slide the parchment and dough onto your rimmed baking sheet.
Spoon the blueberry filling onto the center of the dough, spreading it into an even layer and leaving a 2-inch border all around. Fold the dough border up and over the outer edge of the filling in overlapping sections, pressing gently to hold.
Refrigerate the assembled galette for 10 to 15 minutes while you preheat the oven to 400°F (205°C) with a rack in the center position.
Beat the egg with 1 teaspoon of water, then brush it evenly over the folded crust border, avoiding the parchment paper. Sprinkle turbinado sugar generously over the brushed crust.
Bake for 30 to 35 minutes, until the crust is deep golden brown and the blueberry filling is bubbling and thickened. If the edges brown too quickly, loosely tent them with small pieces of foil.
Let the galette cool on the baking sheet for at least 15 to 20 minutes to allow the filling to set. Slice into wedges and serve warm with vanilla ice cream or whipped cream.
Notes
Keep the butter very cold throughout the dough-making process. If your kitchen is warm, chill your mixing bowl before you start.
Do not skip the 1-hour dough chill time. It is essential for a flaky, tender crust that holds its shape during baking.
Pat the blueberries completely dry before mixing the filling. Any excess surface moisture can lead to a soggy galette bottom.
The galette dough does not need to be a perfect circle. Ragged edges and an uneven shape are part of its rustic charm.
If using frozen blueberries, do not thaw them first. Increase the cornstarch to 2 tablespoons and add 5 extra minutes to the baking time.
Make ahead: The dough can be made up to 2 days in advance and refrigerated, or frozen for up to 1 month. Thaw overnight in the refrigerator before rolling.
Store leftovers covered at room temperature for up to 1 day, or in the refrigerator for up to 4 days. Reheat in a 325°F oven for 10 to 15 minutes to restore crust crispness.
To freeze the baked galette, wrap tightly in plastic wrap then foil and freeze for up to 1 month. Thaw overnight in the refrigerator before reheating.
For extra lemon flavor, double the lemon zest and add 1/2 teaspoon of lemon extract to the filling.
