Wash the strawberries and cut them into round slices as you see in the picture, put them in a bowl and add the juice of one lemon.
Add the sugar and mix well. Let the strawberries rest in the refrigerator for at least 15 minutes.
Turn on the oven to 375°F (190°C) in static mode.
Place shortcrust pastry with background paper in a round baking dish. Add the strawberries. Try NOT to put all of the remaining liquid in the bottom of the bowl.
Fold the perimeter of the pastry toward the inside of the galette, trying to give it a nice shape.
Brush oat milk on the pastry frame. This will make the pastry more golden.
Add a sprinkle of sugar on the frame to give a nice glossy effect to your galette.
Bake for 40-45 minutes at 200°C (375°F) or until the galette is golden brown.
Notes
Tips:
When you transfer the strawberries to the shortbread, be sure to remove as much liquid as possible so the galette does not become too wet.
I used very little sugar for this cake but the amounts can be adjusted according to individual tastes.
You can serve your Galette with vegan vanilla or hazelnut ice cream or custard.
