Ingredients
  

Main Ingredients
  • 2 sheets frozen puff pastry thawed
  • 0.5 pound deli ham thinly sliced
  • 0.5 pound cheese (Gruyere, Swiss, or cheddar) sliced
  • 2 tbsp Dijon mustard
Topping & Egg Wash
  • 1 large egg
  • 1 tbsp milk or water
  • 1 tbsp fresh chives finely chopped
  • 0.5 tsp coarse flaky sea salt
  • 0.25 tsp black pepper freshly cracked

Equipment

  • Baking sheet
  • Parchment paper
  • Pastry brush
  • Pizza cutter or sharp knife

Method
 

  1. Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
  2. Lightly flour a work surface and roll out the thawed puff pastry sheets to smooth any creases.
  3. Spread Dijon mustard evenly over one sheet of pastry, leaving a 1/2-inch border around the edges.
  4. Layer the thinly sliced ham evenly over the mustard, followed by an even layer of the sliced cheese.
  5. Place the second sheet of puff pastry directly on top and press the edges gently to seal.
  6. Using a sharp knife or pizza cutter, slice the large pastry into 9 equal squares. Transfer squares to the prepared baking sheet.
  7. Whisk the egg and milk together. Brush the top of each square lightly with the egg wash.
  8. Sprinkle the chopped chives, sea salt, and black pepper evenly over the tops of the pastries.
  9. Bake for 18-22 minutes until puffed, golden brown, and the cheese is melted and bubbling.
  10. Let cool for 5 minutes on the baking sheet before serving.

Notes

To ensure maximum flakiness, keep the puff pastry as cold as possible before it goes into the oven. If the dough gets too warm during assembly, chill the baking sheet in the fridge for 10 minutes before baking.
