Ingredients Method Notes

Ingredients
  

  • Pastry: 2 sheets frozen puff pastry thawed, approx. 17.3 oz.
  • Fillings: 10 oz sliced deli ham 8 oz Gruyère cheese slices, 2.7 fl oz Dijon mustard (optional).
  • Finishing: 1 large egg whisked, Everything bagel seasoning (optional).

Method
 

  1. Prep: Preheat oven to 425°F. Line a large baking sheet with parchment paper. Ensure your puff pastry is thawed but still cold to the touch for the best rise.
  2. Cut: Roll out each sheet slightly on a lightly floured surface. Slice each sheet into six equal rectangles (12 total).
  3. Layer: Brush the edges of each rectangle with the whisked egg. Spread a small amount of Dijon mustard in the center. Place one slice of Gruyère and a folded slice of ham on top.
  4. Fold: Lift one corner of the pastry toward the center, then fold the opposite corner over it to create a "blanket" effect. Press gently to seal where they overlap.
  5. Wash & Season: Transfer to the baking sheet. Brush the tops of the pastries with the remaining egg wash and sprinkle with everything bagel seasoning.
  6. Bake: Bake for 18–22 minutes until the pastry is puffed high, golden brown, and the cheese is bubbly.
  7. Cool: Let them rest for 5 minutes before serving so the cheese doesn't run out.

Notes

  • Pastry Tip: If the dough becomes too soft or sticky while you are working, pop it in the fridge for 10 minutes. Cold fat (butter/shortening) in the dough is what creates those distinct flaky layers.
  • Cheese Swap: If Gruyère is too pricey, Jarlsberg or a sharp white cheddar are excellent substitutes.
  • Make Ahead: You can assemble these, freeze them on a tray, and then store them in a bag. Bake straight from frozen (just add 3–5 minutes to the bake time).
