These ham mozzarella puff pastry stacks sandwich thin ham and two melty cheeses between flaky layers of golden pastry. They bake in twenty minutes and feel like a bakery treat made from the freezer aisle.
Store bought puff pastry does the heavy lifting, so the work is cutting, stacking, and brushing with egg. Serve them warm for brunch, lunch boxes, or an easy appetizer tray.

Why This Ham Mozzarella Puff Pastry Stacks Recipe Works
Puff pastry puffs into dozens of flaky layers in a hot oven, so a few simple fillings feel special without any dough to make.
Using both mozzarella and sharp cheddar gives you stretch from one cheese and sharp flavor from the other.
Sealing the edges with a fork and brushing with egg keeps the filling inside and gives the tops a deep golden shine.
Ingredients for Ham Mozzarella Puff Pastry Stacks
- You need two sheets thawed puff pastry, eight ounces thinly sliced ham, one cup shredded mozzarella, and one cup shredded sharp cheddar.
- Add one egg for the wash, one tablespoon Dijon mustard, two tablespoons flour for dusting, and one quarter teaspoon black pepper.
Puff pastry. Thaw it in the refrigerator until pliable but still cold. Warm pastry gets sticky and bakes flat.
Ham. Thin deli slices fold neatly and stay tender. Pat them dry so they do not make the pastry soggy.
Mozzarella. Low moisture shredded mozzarella melts without leaking water into the pastry.
Sharp cheddar. Aged cheddar adds tang that balances the mild ham.
Egg wash. A beaten egg gives color and acts like glue for the seams. Add a teaspoon of water for an even coat.
How to Make Ham Mozzarella Puff Pastry Stacks
1. Heat the oven. Heat the oven to 400 degrees F and line two baking sheets with parchment.
2. Cut the pastry. Unfold each pastry sheet on a floured surface and cut it into six equal rectangles.
3. Layer the filling. Spread a thin layer of mustard on six rectangles, then add ham, mozzarella, and cheddar, leaving a half inch border.
4. Top and seal. Cover each with a second rectangle, press the edges, and crimp them closed with a fork.
5. Add the wash. Brush the tops with the beaten egg and sprinkle with pepper. Cut a small slit in each top for steam.
6. Bake. Bake for eighteen to twenty minutes, until puffed and deep golden, and cool for five minutes before serving.
Keep the pastry cold while you work. If the dough softens, slide the sheet pan into the refrigerator for ten minutes before baking, because cold butter in the dough is what creates the flaky layers.
How to Serve Ham Mozzarella Puff Pastry Stacks
Serve the stacks warm with mustard or a creamy dip like white queso dip. For a brunch table, add a puff pastry baked brie and ricotta and spinach puff pastry bites, with apple turnovers for dessert.
How to Store and Reheat Ham Mozzarella Puff Pastry Stacks
Cool the stacks, then refrigerate in an airtight container for up to three days. Reheat on a baking sheet at 350 degrees F for about ten minutes to crisp the pastry again. Do not use the microwave, which turns the layers soft.
Tips and Variations for Ham Mozzarella Puff Pastry Stacks
Flag the allergens. This recipe contains wheat, milk, and eggs. Check the pastry and ham labels if anyone has a food allergy.
Do not taste raw egg. Wash your hands and brush after handling the egg wash and never taste it before baking.
Use flour sparingly. Too much flour on the counter makes the pastry dry and tough, so dust lightly.
Cut cleanly. Use a sharp knife or pizza cutter and press straight down so the layers do not seal shut.
Chill before baking. Ten minutes in the refrigerator helps the pastry puff higher.
Swap the cheese. Swiss or Gruyere gives a nutty flavor in place of cheddar.
Freeze ahead. Assemble without the egg wash, freeze on a tray, then bake straight from frozen with five extra minutes.
Check trusted guidance. Review the University of Wisconsin Extension leftovers guidance for safe storage times.
