Preparation time

10 minutes

Cooking time

35 minutes




For the filling

  • 1 tbsp olive oil
  • 2 medium leeks, trimmed and sliced into discs
  • 3 cloves garlic, minced
  • 500g button mushrooms
  • 1 tsp dried mixed herbs
  • A pinch of salt and pepper

For the sauce

  • 1 tbsp dairy-free butter*
  • 2 tbsp plain flour
  • 350 ml dairy-free milk
  • 1/8 tsp ground nutmeg
  • A pinch of salt and pepper

For the crust

  • 1 roll vegan puff pastry (or gluten-free, if needed)**
  • 4 tbsp dairy-free milk, for glazing

* Dairy-free brands include Vitalite, Pure and Flora Freedom

** Most supermarket own-brand ready-rolled pastry is dairy-free, as is the Jus-Rol brand


1. Add the olive oil to a large saucepan on a medium heat. Fry the leeks and garlic for 2 minutes, to soften.

2. Add the mushrooms, herbs, salt and pepper and stir for a minute. Place the lid on top and cook for 8 minutes.

3. Meanwhile, in a small saucepan, melt the dairy-free butter on medium heat. Add the flour and stir until combined. Slowly add in the milk, a tablespoon at a time and whisk, until you have a smooth thick mixture. Stir in the nutmeg and season with salt and pepper.

4. Combine the cooked leeks and mushrooms with the sauce and leave to cool completely.

5. Make sure your puff pastry is at room temperature (if using frozen, leave at room temperature overnight) and preheat the oven to 200C.

6. Add the leek and mushroom mixture to a pie dish and top with the puff pastry, cutting off any excess pastry around the edges.

7. Crimp the edges using a fork and score a criss-cross pattern on the top with a sharp knife. Finally, dip a pastry brush in a little dairy-free milk and brush the top of the pie, to help it brown.

8. Cook for 25 minutes until golden brown. Serve straight away.
