Butternut, potato & Gruyère pithiviers

These individual pies are simple to prepare and, with their rich, creamy filling, they only need a sharp, leafy salad to serve alongside 

  • Preparation time: 15 minutes
  • Cooking time: 25 minutes to 30 minutes
  • Total time: 45 minutes

Serves: 4

Ingredients

Plain flour, for dusting
2 x 500g packs puff pastry
3 tbsp half-fat crème fraîche
2 cloves garlic, crushed
2 tbsp chopped lemon thyme
250g butternut squash, peeled, deseeded and cut into thin slices
200g red-skinned potatoes, peeled and thinly sliced
50g Gruyère cheese, grated
1 medium Waitrose British Blacktail Free Range Egg, beaten 

Method

1. Preheat the oven to 200°C, gas mark 6. Line 2 baking trays with baking parchment. On a lightly floured surface, roll out one of the puff pastry packs to about 24 x 24cm. Using either a pastry cutter or a bowl measuring 10cm in diameter as a template, cut out 4 discs. Place 2 pastry discs on each tray.

2. Repeat with the remaining pastry but making the discs slightly bigger than the first ones — about 12cm in diameter. Set aside in the fridge.

3. Place the crème fraîche in a bowl, add the garlic, lemon thyme and some seasoning and mix well.

4. Spoon a teaspoon of the mixture into the centre of the discs on the baking trays, then arrange a few slices of butternut squash and potato on top. Sprinkle with a little Gruyère and then repeat the layers again, starting with another teaspoon of the crème fraîche mixture.

5. Brush the edges of each filled pastry disc with a little egg and then carefully place a larger disc of pastry over the top of the filling, pressing down well. Pinch the pastry together to seal. Using the blunt side of a small knife, make semi-circular lines on the top of each pie, running from the centre to the edge, making sure you just score the pastry without cutting through it. Brush with beaten egg and place in the fridge to chill for at least 10 minutes.

6. Place the trays in the oven and bake for 25–30 minutes until golden, cooked on the top and bottom and the vegetables are tender when pierced with a knife. Leave to stand for about 5 minutes before serving.
