To a food processor, add 1½ cups all-purpose flour, 2 tablespoons sugar, ¼ teaspoon salt, 5 ounces butter (cold and diced).
Pulse a few times until the butter has absorbed the flour. Add 1½ tablespoons iced water and pulse a few more times till you have a crumbly dough.
Transfer the dough to a worktop and compact it into a disc. Put it in an air-tight container and let rest in the fridge for 15 to 30 minutes.
MAKE BLUEBERRY FILLING
Rinse 3 cups blueberries with cold water and add them to a bowl while still wet.Add ¼ cup sugar, 1 teaspoon lemon zest, 1 tablespoon lemon juice, 2 tablespoons all-purpose flour and 1 tablespoon vanilla extractToss with a spoon.
SHAPE BLUEBERRY GALETTE
Preheat oven to 400°F or 200°C. Take pastry dough out of the fridge and place it on a worktop between two sheets of parchment paper.Roll out the dough with a rolling pin. Try to get a roughly round shape 13 inches or 33 cm wide.Transfer the dough and the parchment paper to a baking sheet. Remove the paper on top (you can save it and reuse it for another recipe).
Arrange the blueberry mixture in the center. Leave about 1.5 inches or 4 cm at the edges.
Fold the pastry around the berries, pulling the corners of the parchment paper towards the center (see video recipe).Brush the edges with water, then sprinkle with a few pinches of sugar.
Bake at 400°F or 200°C for 30 to 35 minutes or until golden brown.Let cool down for at least 30 minutes before slicing and serving.
We recommend serving it with a scoop of vanilla ice cream or whipped cream (of course non-dairy alternatives work well here).
