Unroll your shortcrust pastry onto a large lined baking tray. Trim the corners to make a rough oval shape.
1 sheet (320g) Ready-made Shortcrust Pastry
Assemble the galette:
Spoon the peach mixture into the centre of the pastry, leaving a border all around. Or you can arrange the peach slices in a pretty pattern.
Fold the edges over the fruit, pleating as you go, leaving the centre exposed.
Beat the egg and milk together to make an egg wash, then brush the pastry edges with it. Stir the sugar and cinnamon together, then sprinkle over the galette for extra crunch.
Pop in the fridge for 20 minutes to chill and firm up the pastry. Meanwhile, preheat your oven to 180°C fan / 200°C conventional.
Bake the galette:
Bake for 30–35 minutes, or until the pastry is golden and crisp, and the peaches are bubbling up in the middle.
Cool slightly before slicing and serving. This peach galette is delicious warm or at room temperature with vanilla ice cream, clotted cream or Greek yoghurt!
