For the crust

  • a little less than 1/2 cup butter, softened (cut in cube packed) 100g
  • 1 and 1/3 cup flour  200g
  • 1 pinch salt
  • 1/4 cup water or less

For the filling

  • 1 tbsp olive oil
  • 1 cup mushrooms
  • 1 cup spinach
  • 4 eggs medium
  • 100 ml milk 2%
  • 100 ml heavy cream


  • Preheat the oven at 350F.

For the crust

  • Mix the butter, the flour and salt together until it is crumbly.
  • Add in the water gradually as you might need a few drops less. Form into a ball and set in the fridge for 20 minutes or so. 
  • Roll the dough on a lightly floured surface.

For the Quiche filling

  • Clean with a damp paper, clean the mushrooms and slice them up.
  • Clean and chop the spinach.
  • In a hot pan, with some olive oil, sauté the mushroom and spinach for about 4-5 minutes on medium heat.
  • Spread on the crust. Set aside.
  • In a bowl, whisk the eggs and add in the milk and the heavy cream. Mix and add salt and pepper to taste.
  • Pour the mixture over in the crust with the spinach and mushrooms. Sprinkle the cheese over.
  • Bake in the oven for 30 minutes or until the crust is golden and the top also.
  • Slice and enjoy!
