1 knob unsalted butter
1 celeriac (about 800g), peeled and cut into small cubes
2 leeks, trimmed and sliced
2 garlic cloves, finely chopped
200g chestnut mushrooms, sliced
2 tsp thyme

300ml fresh vegetable stock, heated
100g full fat soft cheese
1 tbsp wholegrain mustard

Heat the butter in a large pan and cook the celeriac and leeks for 5 minutes. Add the garlic, mushrooms and thyme and cook for a further 5 minutes, then stir in the flour and cook for 1 minute. Stir in the stock, cover and simmer for 15 minutes or until the celeriac is tender.
Stir the soft cheese, mustard and cheddar into the mixture, then remove from the heat. Season and tip into a large ovenproof dish; set aside to cool.
Preheat the oven to 200°C, gas mark 6. Cover the filling with the pastry sheet, trimming if necessary, and tuck in the edges. Brush with the beaten egg and bake for 30 minutes, until risen and piping hot. Leave to cool a little before serving. SF
