Frequently Asked Questions
Can I use puff pastry cups instead of sheets?
Yes! Thaw the cups, fill them with diced ham and cheese, and bake until puffed and golden. They make adorable individual bites with even less effort.
What’s the best way to keep the bottom from getting soggy?
Bake on a preheated baking sheet or a pizza stone if you have one, and make sure your ham and any condiments are not overly wet. A light sprinkle of breadcrumbs or grated Parmesan on the bottom pastry before layering can also absorb excess moisture.
Can I make these without egg?
You can brush the tops with milk, cream, or melted butter for browning, but the deep golden color and sheen won’t be quite the same. The egg wash truly makes a difference in appearance and crispness.
My pastry didn’t puff up. What went wrong?
Puff pastry needs high heat, a cold start, and enough space between pieces. Make sure your oven is fully preheated, your pastry was cold when it went in, and you haven’t overloaded the filling. Old or improperly thawed pastry can also fail to rise.
Can I make a sweet version?
Absolutely! Swap the ham and cheese for a thin layer of Nutella, a sprinkle of cinnamon sugar, or a fruit preserves and cream cheese filling. Use a dusting of powdered sugar instead of egg wash for a sweet finish.

Prep Time:
15 minutes
Cook Time:
18–22 minutes
Cool Time:
5 minutes
Total Time:
35–42 minutes
Yield:
16–25 squares
Ingredients
- 1 package (17.3 oz / 2 sheets) frozen puff pastry, thawed but cold
- 8 oz thinly sliced ham (Black Forest, smoked, or Virginia)
- 1½ to 2 cups shredded cheese (Gruyère, sharp cheddar, Swiss, or a blend)
- 1 egg, for egg wash
- 1 tablespoon water or milk
- Optional: 1–2 teaspoons Dijon mustard, flaky sea salt, sesame seeds, poppy seeds, or fresh chopped herbs for topping
Instructions
- Preheat oven to 400°F (200°C). Line two baking sheets with parchment paper.
- Prepare the pastry. On a lightly floured surface, gently unfold one sheet of puff pastry and roll it to smooth the creases into a roughly 10-inch square. Repeat with the second sheet.
- Add mustard (if using). Spread a very thin layer of Dijon mustard over one sheet of pastry, leaving a ½-inch border.
- Layer ham and cheese. Arrange the ham in an even layer over the mustard, then sprinkle the shredded cheese on top, keeping the border clear.
- Top and seal. Place the second puff pastry sheet on top. Press the edges firmly to seal, then crimp with a fork.
- Egg wash and cut. Beat the egg with the water. Brush the top evenly with egg wash. Sprinkle with any desired toppings. Using a sharp knife or pizza cutter, cut the pastry into squares (about 4×4 or 5×5 grid). Transfer squares to the prepared baking sheets, spaced an inch apart.
- Bake until golden. Bake for 18–22 minutes, rotating pans halfway, until deeply golden, puffed, and crisp. Let cool on the sheet for 5 minutes before serving warm.
Notes
- Work quickly with cold pastry for the flakiest rise. If the dough becomes sticky, refrigerate for 10 minutes.
- For neat, even squares, chill the filled pastry sheet in the freezer for 10 minutes before cutting.
- To make ahead, assemble, cover, and refrigerate unbaked squares for up to 24 hours. Bake from cold, adding 2–3 minutes to the time.
- Freeze unbaked squares in a single layer, then store in a freezer bag. Bake from frozen, adding 5–8 minutes.
