Leek, Mushroom & Gruyere Pie

  • Time preparation 15min
  • cook time 30min
  • Serve Serves 6

  • 3 medium potatoes, peeled and cut into cubes
  • 1 tbsp sunflower oil
  • 400g pack leeks, trimmed and roughly chopped
  • 300g pack chestnut mushrooms, quartered
  • 200g creme fraiche
  • 100g Gruyere, grated
  • 320g pack puff pastry sheet
  • 1 medium egg, beaten

Preheat the oven to 200°C, Gas Mark 6. Parboil the potatoes for 5 minutes and drain. While the potatoes are boiling, heat the oil in a medium saucepan and gently sweat the leeks and mushrooms for 4-5 minutes until beginning to soften.

Stir through the creme fraiche and grated cheese, and add the parboiled potatoes. Season with a small pinch of salt and some black pepper.

Place the filling in a medium rectangular baking dish just a little smaller than the pastry sheet, and top with the sheet of puff pastry, cutting away any excess and pressing down the edges. To really impress, make a sweet decoration from the excess pastry and simply stick on with some beaten egg.

Brush all over with beaten egg and cut a hole in the top to allow steam to escape. Bake in the oven for 25-30 minutes or until golden and bubbling.
