Method

  1. Blitz 50g walnuts with the plain flour in a food processor until finely ground, then add the butter. Pulse a few times until the mixture resembles breadcrumbs. Add the egg yolk and 1 tbsp cold water and pulse again until just combined. Tip out onto a lightly floured surface and knead briefly to make a soft dough. Flatten to a disc, wrap in clingfilm and transfer to the fridge for 30 mins.
  2. Meanwhile, preheat the oven to gas 6, 200°C, fan 180°C. Heat the oil in a large frying pan over a high heat and cook the mushrooms for 7-10 mins until well browned. Add the garlic and thyme and cook for 1 min. Season lightly and set aside.
  3. Roll out the chilled pastry on a lightly floured surface into a large circle about 26cm, then use to line a 22cm tart case. Scrunch up a large piece of baking paper and use it to line the pastry case, then fill the tin with baking beans. Blind-bake for 15 mins, then remove the beans and paper and bake for 5 mins until the pastry is slightly golden and dry to the touch. Reduce the oven to gas 4, 180°C, fan 160°C. Leave to cool for 20 mins.
  4. Beat together the 3 eggs, cream, milk and Parmesan; season. Arrange the mushrooms in the tart case, then pour over the egg mixture. Top with the prosciutto slices, remaining chopped walnuts and extra thyme sprigs. Bake for 35-40 mins until golden and set. Leave to cool for at least 30 mins before serving.
