Transfer the rolled pastry onto a parchment covered baking sheet before filling.
Arrange the apples (not the juice) on the puff pastry leaving a 2" border or more if making a larger galette.
Gently fold the edges of the pastry over the apples, pleating as you go.
Sprinkle crumble topping generously over the apple filling (not the pastry).
Brush the pastry edges with plant-based milk.
Place straight into the oven on the center rack of preheated oven. Bake until golden and cooked through. About 35-40 minutes. Mine takes exactly 38 minutes.
For best results, let the tart cool for 10-15 minutes before slicing.
Serve with a scoop of ice cream, whipped cream or salted caramel drizzle for extra indulgence.
