Chestnut and Mushroom Pie

A vegetable pie that is full of autumnal flavours appropriate to the festive season. This is an elegant addition to your Thanksgiving or Christmas dining table and suitable for Dairy Free, Gluten Free and Vegan diets.

Pumpkin, mushroom and chestnut make for a rich, tasty pie. I usually make a roll with puff pastry. enabling it to be easily sliced. However, it works equally well as a deep pie.

For Diabetic, Low Calorie or Low Fat, it is preferable to make a pie with a crustless bottom. The recipe forGluten Free pastry (which, being a mix of cornmeal and potato and with only a small quantity of butter or alternative, is Low Fat) provides a crisp crust and is very suitable for this pie. Alternatively, style this as if it were a shepherd’s pie, ie topping the vegetable mix with mashed potato.

As with any pie there are a few steps in constructing this dish particularly if you make a more decorative pie, as illustrated here. However, it is not difficult and can be prepared well in advance, allowing you to spend more time with guests.
