Potato and Mushroom Pie

Potato and Mushroom Pie

By Denise PhillipsPublished on 09 September 2021Potato and mushroom pie is simple to prepare and can be made in advance and reheated. Delicious sautéed mushrooms are surrounded with creamy mashed potato. Try using a mixture of mushrooms for a deeper mushroom flavour – like oyster, brown cap, shiitake and button. When you begin frying the mushrooms they’ll suddenly release lots of liquid – just continue to cook them until all the liquid is absorbed. This pie is best served with a green salad, topped with toasted almonds.
