  • Remove from heat and set aside to cool.

Prepare the hand pies.

  • Preheat the oven to 400º F (200C) and line a baking sheet with parchment paper.
  • Unfold puff pastry and use a rolling pin to roll it out a bit to make it wider.
  • Cut the dough into 6 pieces.
  • Divide grated cheese. Top with mushroom mixture and caramelized onion.
  • Brush the edges with beaten egg and fold the dough over the filling.
  • Use a fork to press the edges together to seal.
