Pumpkin, Chestnut and Mushroom Pie

Pumpkin, chestnut and mushroom pie; the perfect winter warmer. This recipe is a real treat for the entire family. The pie is completely vegan and can be adapted to suit your needs! We have had it with both pumpkin and creamy butternut squash, both which work really well. In addition, we have tried it with added carrots as well as brussel sprouts; both work a treat!

The mushrooms add a meaty and earthy flavour, with sweetness from the squash/ pumpkin and the perfect texture from the chestnuts. The pie topping is a no-fuss rolled puff pastry, because no one makes puff pastry! You can also try with a short crust pastry if you wanted to switch it up a bit 🙂

Here we have some pictures which show the cooking process. We find that pictures help guide recipes and we also have a reel on Instagram for further reference!

All ingredients cooking together, ready to be thickened! Here we didn’t have a large enough pan so had to separate between two pans, hence the low level fluid. Yours may look slightly different 🙂

Electric ovens cook quicker than gas so keep an eye out. This pie was using electric and it came out a lot darker than when using gas for the same amount of time!

We use fresh herbs in the pie as the flavours are divine! However, when we have not had them in the house, or wanted to go to the shops, we have used dried mixed herbs. Although these work well, they don’t have the same impact as the fresh herbs but it is entirely your choice!

This meal is great served on its own however, feel free to add boiled potatoes or a side of vegetables if you wish! For reference we use ready made puff pastry and light miso paste.
