Prepare the dough: Dust your working surface with flour. Roll out the dough and spread softened butter as you fold and layer it to create flakiness. Brush lightly with vegetable oil.
Prepare the filling: Mash boiled potatoes with cream, butter, salt, and pepper. Add optional cheese or herbs if desired.
Assemble the pie: Place the mashed potato filling onto the prepared dough. Fold or cover the dough to enclose the filling. Seal the edges carefully.
Brush with egg yolk: Brush the top of the pastry with egg yolk to achieve a golden, glossy finish.
Bake: Preheat the oven to 375°F (190°C) and bake for 25–35 minutes, or until the pastry is golden brown and crisp.
Serve: Let the pie cool slightly before slicing. Serve warm.
