Crispy Ham Cheese Stacks (Printable Recipe)

Golden puff pastry squares filled with ham, gooey cheese, and a touch of mustard for a flavorful snack.

# Ingredients You'll Need:

→ Pastry

01 - 1 package (17.3 oz) frozen puff pastry sheets, thawed

→ Meat

02 - 8 slices thinly sliced ham

→ Cheese

03 - 8 slices cheese (Swiss, Gruyère, or Cheddar recommended)

→ Wash

04 - 1 large egg, beaten
05 - 1 tablespoon milk

→ Condiments & Seasoning

06 - 1 tablespoon Dijon mustard
07 - Salt and freshly ground black pepper, to taste

→ Garnish (optional)

08 - Fresh thyme or rosemary sprigs

# Steps to Follow:

01 - Set the oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking.
02 - On a lightly floured surface, roll out thawed puff pastry sheets to smooth creases and slightly enlarge them. Cut each sheet into four equal square pieces, yielding eight squares total.
03 - In a small bowl, whisk together the beaten egg and 1 tablespoon of milk until combined.
04 - Place one slice of ham on each pastry square, optionally spreading a thin layer of Dijon mustard on the ham before topping with a cheese slice. Season lightly with salt and pepper, then sprinkle fresh herbs if using.
05 - Top each ham and cheese stack with another pastry square. Press edges gently to seal, then crimp with a fork to secure and add a decorative pattern.
06 - Brush the entire surface of each pastry stack with the prepared egg wash to promote golden, glossy browning.
07 - Arrange stacks on the baking sheet, spacing them apart to allow for expansion. Bake for 20–25 minutes until puffed and golden brown.
08 - Remove from oven and let the stacks cool slightly on the baking sheet to allow layers to set and cheese to remain melty.

# Extra Tips:

01 - To store leftovers, refrigerate cooled stacks in an airtight container for up to 2 days. Reheat in a toaster or conventional oven at 350°F (175°C) to restore crispiness. Avoid microwaving to prevent sogginess.
02 - For a flavor variation, add caramelized onions or a slice of ripe tomato between ham and cheese.
