This impressive pie is packed with so many rich, hearty flavours that it not only makes an excellent vegetarian Christmas recipe, but it can serve as an alternative Christmas main for meat-lovers as well. You can even make this pie a month in advance and cook it straight from frozen, for minimal effort on the day.
- Preheat the oven to gas 4, 180°C, fan 160°C. Heat 2 tbsp oil in a large lidded pan over a medium heat. Add the squash, season, then cover and cook for 10 mins, until softened.
- Add the onions and cook for 5 mins. Add the garlic and chilli and cook for 1 min more. Tip the mixture into a bowl and set aside.
- Heat the remaining oil in the same pan. Add the mushrooms and fry for 1-2 mins. Remove from the heat and add to the bowl with the squash.
- Meanwhile, put the spinach in a colander set over the sink. Pour over a kettleful of boiling water to wilt. Squeeze out the excess water; season.
- Grease a 22cm springform tin with butter. Brush 1 sheet of filo with butter and line the base of the tin, leaving an overhang. Repeat with 4 more sheets, layering each one at different angles for folding up later.
- Fill with half the veg mixture, followed by half the spinach, and then half the cheese. Add the remaining spinach, then top with the remaining veg mixture and cheese. Fold the final filo sheet in half and use to cover the filling. Fold over the overhanging pastry and scrunch up the ends. Brush with melted butter and bake for 45 mins, or until golden and crisp. Leave to cool in the tin for 10 mins before serving.
