ingredients

  • 2 tablespoons unsalted butter
  • 2 tablespoons minced garlic
  • 2 cups chopped leeks
  • 12 ounces Baby Bella or white mushrooms, sliced `
  • 5 tablespoons cream cheese, cubed
  • 2 1/2 teaspoons Better Than Bouillon Mushroom Base
  • 1 1/2 tablespoons all-purpose flour
  • 3/4 cup Parmesan cheese, grated
  • 2 sheets frozen puff pastry, thawed
  • 1 large egg, beaten (for egg wash)

Method

  • Step 1

    Preheat the oven to 400°F. Line a baking tray with parchment paper.

  • Step 2

    Melt the butter in a large saucepan over medium heat. Add minced garlic and sauté for 20 seconds, until fragrant. Stir in the chopped leeks and cook for about 15 minutes, stirring every 3 minutes, until the leeks are lightly browned.

  • Step 3

    Add the sliced mushrooms to the pan and sauté for an additional 3 minutes.

  • Step 4

    Stir in the Better Than Bouillon Mushroom Base and cubed cream cheese, cooking for another 3 minutes until the cream cheese is fully incorporated.

  • Step 5

    Sprinkle the flour into the mixture and stir continuously for 2 minutes to allow it to thicken. Remove from heat and transfer the mixture to a large bowl. Let it cool for about 20 minutes.

  • Step 6

    Once cooled slightly, fold in the grated Parmesan cheese and mix until evenly combined. Set the filling aside.

  • Step 7

    Cut each thawed puff pastry sheet into 4 equal squares to make 8 pieces total. Gently roll each square with a rolling pin to create a rectangle.

  • Step 8

    Place 2–3 tablespoons of the filling onto one half of each rectangle. Fold the pastry over the filling to form a smaller rectangle, then seal the edges by pressing with a fork. Transfer the pastries to the prepared baking tray.

  • Step 9

    Brush the tops of each pastry with the beaten egg to ensure a golden, glossy finish.

  • Step 10

    Bake for 30–35 minutes, or until the pastries are puffed and golden brown.

  • Step 11

    Remove the pastries from the oven and allow them to cool for 5 minutes before serving.
