Preheat the oven to 375°F (190°C). Line two baking sheets with parchment paper.
02 -
In a large bowl, combine the strawberries, granulated sugar, cornstarch and vanilla paste. Set aside to macerate slightly.
03 -
Working with one sheet of puff pastry at a time, roll out on a lightly floured surface until slightly thinner. Cut each sheet into four equal rectangles for a total of eight pieces.
04 -
Divide the rectangles between the prepared baking sheets. Spoon about ½ cup of the strawberry mixture into the center of each puff pastry rectangle. Fold the edges up around the filling, pleating as needed, to form mini galettes.
05 -
Brush the pastry edges with the whisked egg and sprinkle generously with demerara sugar. Bake until the edges are puffed and deeply golden brown, 25 to 30 minutes.
06 -
Allow to cool completely before serving. Top each galette with softly whipped cream and a sprinkle of chopped pistachios.
