Crispy ham and cheese puff pastry stacks

by
Crispy ham and cheese puff pastry stacks are an absolute crowd-pleaser! They feature layers of buttery, ultra-flaky puff pastry, savory melted cheese, smoky ham, and a hint of sharp mustard. They look impressive, but they come together with just a handful of ingredients.

Here is an easy, foolproof recipe to make them at home.

Ingredients

  • Puff Pastry: 1 package (2 sheets) frozen puff pastry, thawed in the refrigerator
  • Ham: $\frac{1}{4}$ to $\frac{1}{2}$ pound of thinly sliced Black Forest or honey ham
  • Cheese: 1.5 cups grated Gruyère, Swiss, or sharp cheddar cheese (Gruyère gives a wonderful, nutty melt)
  • Mustard: 2 tablespoons Dijon or honey mustard
  • Egg Wash: 1 large egg whisked with 1 tablespoon of water or milk
  • Optional Finish: A pinch of everything bagel seasoning or extra grated cheese for the top

Step-by-Step Instructions

  1. Prep the Oven & Pan: Preheat your oven to 200°C (400°F). Line a large baking sheet with parchment paper.
  2. Roll the Pastry: Lightly flour your work surface and unfold your thawed puff pastry sheets. Gently roll them out just enough to smooth out the creases.
  3. Build the Base Stack: Lay the first sheet of puff pastry flat. Brush it evenly with the Dijon mustard, leaving a small 1-inch border around the edges. Layer the thin slices of ham evenly over the mustard, then cover generously with your grated cheese.
  4. Top and Seal: Brush the bare borders of the bottom pastry with your egg wash. Carefully lay the second sheet of puff pastry directly on top. Press down lightly around the edges to seal them together.
  5. Score and Wash: Brush the top pastry sheet generously with the remaining egg wash (this ensures a golden, shiny crunch). Cut 3 to 4 small slits across the top crust with a sharp knife to let steam escape.
  6. Bake: Bake for 20 to 25 minutes, or until the pastry is completely puffed, deeply golden brown, and crisp.
  7. Slice and Serve: Let the large stack rest on a cooling rack for 5 minutes (this helps the melted cheese set slightly). Use a sharp knife to cut it into neat squares or rectangles, and serve warm!

Pro-Tips for Maximum Flakiness

  • Keep it cold: Puff pastry relies on cold butter to create its flaky layers. If your dough gets too warm and sticky while assembling, pop the whole assembly into the fridge for 10 minutes before baking.
  • The knife trick: When cutting your baked stacks into squares, use a swift, straight downward motion with your knife. Avoid sawing back and forth, which can squish the delicate layers.
Are you serving these as a party appetizer, or keeping them for a quick weekend lunch?
