Ingredients

Scale

Filling

  • 2 cups mushrooms, sliced
  • 1 cup leeks, sliced
  • 1 tablespoon olive oil
  • 1 teaspoon thyme
  • 1 tablespoon flour
  • 1 cup vegetable broth
  • 1 tablespoon soy sauce
  • 1 tablespoon cream (or plant-based alternative)
  • Salt and pepper to taste

Pie Crust

  • 1 sheet of puff pastry


Instructions

  1. Preheat Oven: Preheat the oven to 400°F (200°C) to ensure it reaches the proper temperature for baking the pie evenly.
  2. Sauté Leeks: Heat olive oil in a pan over medium heat and sauté the sliced leeks until they become soft and translucent, releasing their natural sweetness.
  3. Add Mushrooms and Thyme: Add the sliced mushrooms and thyme to the pan. Cook until the mushrooms are tender and have released their moisture.
  4. Incorporate Flour: Stir in the flour and cook the mixture for 1 minute to remove the raw flour taste and help thicken the filling.
  5. Add Broth and Soy Sauce: Gradually pour in the vegetable broth and soy sauce, stirring continuously until the mixture thickens into a creamy sauce.
  6. Finish the Filling: Remove the pan from heat and stir in the cream or plant-based alternative to add richness. Season with salt and pepper to taste.
  7. Prepare Pastry Base: Roll out the puff pastry sheet into a pie dish to form the base of the pie, ensuring it covers the bottom and sides evenly.
  8. Add Filling: Pour the prepared mushroom and leek filling into the pastry-lined dish, spreading it out evenly.
  9. Cover with Pastry: Cover the filling with another sheet of puff pastry. Seal the edges well to prevent leaking, and make slits on the top pastry to allow steam to escape during baking.
  10. Bake the Pie: Place the pie in the preheated oven and bake for 25-30 minutes, or until the pastry is puffed up and golden brown.

Notes

  • For a vegan option, use plant-based cream and ensure the puff pastry is dairy-free.
  • Make sure to seal edges of the pastry well to prevent filling from leaking out.
  • You can substitute thyme with rosemary or sage for a slightly different flavor profile.
  • Use fresh mushrooms for best flavor; button or cremini work well.
  • If puff pastry is frozen, thaw it fully before rolling out to avoid cracking.
