These Savoury Breakfast Tarts are baked upside down with the filling underneath a puff pastry topping, then flipped before serving to help keep the pastry deliciously flaky! Remember to thaw your puff pastry before making this recipe. These stay crispy when reheated in an air fryer or oven, but in a pinch, the microwave will do.
