Mushroom Quiche with Walnut

For short crust pastry:

  • 150 grams all-purpose flour
  • 100 grams cold butter cut into cubes
  • 1 tsp. fine salt
  • 2-3 tbsp. cold water

For mushroom filling:

  • 800 grams champignon or portebello mushrooms
  • 2 tbsp. olive oil
  • Salt and pepper to taste
  • A little grated nutmeg
  • 1 tsp. thyme
  • 1/2 cup dry white wine
  • 50 grams chopped walnuts

For royal sauce:

  • 250 ml. sour cream
  • 2 large eggs
  • 1/4 tsp. salt
  • Ground black pepper
  • 1 tbsp. all-purpose flour
  1. Crust: In a food processor with a steel blade put flour, butter and salt and process until the mixture is crumbly.
  2. Add water gradually until the dough clumps.
  3. Transfer the dough on a lightly floured work surface and create a thin disc-shape. Wrap in plastic wrap and chill for 1 hour.
  4. On a floured work surface, roll the dough about 4 mm thick and line the pan, while ensuring a right angle between the bottom and the sides.
  5. Pierce the bottom of the crust with a fork and cool in the freezer for 1 hour.
  6. Mushroom filling: in a large skillet heat olive oil, add the mushrooms and cook until it loses its volume. Add salt, pepper, thyme and nutmeg to taste.
  7. Cook for another 2 minutes and add in the white wine. Cook over high heat until most of the liquid evaporates.
  8. Strain the mushroom mixture and leave to cool for about 1/2 hour. Stir in the walnuts.
  9. Royal sauce: in a small bowl, whisk sour cream, eggs, salt, pepper and flour into a smooth mixture.
  10. Assemble the quiche: preheat oven to 170 degrees.
  11. Pour the mushroom filling onto the frozen crust in an even layer. Carefully pour over the royal sauce.
  12. Bake for about 40-45 minutes or until golden brown and set.
  13. Serve warm or at room temperature.
  • Instead of walnuts you can use any other nut you like.
  • Keep in a closed container in the refrigerator for up to 3-4 days. It is recommended to warm the quiche slightly before serving.
