For the Filling
- Ham – Salty and savory, your leftover slices will elevate these pastries to something truly special.

Step‑by‑Step Instructions for Flaky Ham and Cheese Puff Pastries
Step 1: Preheat & Prep
Begin by preheating your oven to 400°F (200°C) to ensure a perfectly crispy finish. While the oven warms, line a baking sheet with parchment paper, creating a non-stick surface for your Flaky Ham and Cheese Puff Pastries. This simple prep step ensures an easy cleanup later and prevents the pastries from sticking.
Step 2: Roll & Cut Dough
Next, dust your work surface lightly with flour to prevent sticking. Unroll the puff pastry and roll it out to about 1/8 inch thick if needed. If you’re using Dufour brand, cut the rolled pastry into four equal squares, each roughly 5×5 inches, giving you the perfect base for your savory filling.
Step 3: Layer Ingredients
Take a slice of your leftover ham and place it in the center of each pastry square. Next, sprinkle a generous amount of grated Gruyère cheese over the ham, ensuring it’s positioned nicely to allow for easy folding. This combination will create a delightful burst of flavor in every bite of your pastries!
Step 4: Season Topping
In a small mixing bowl, combine your chosen spices and herbs, such as thyme, black pepper, and a dash of cinnamon for warmth. Sprinkle ¼ to ½ teaspoon of this seasoning mix over the cheese on each pastry square. This step enhances the taste profile and elevates your Flaky Ham and Cheese Puff Pastries to a new level of deliciousness!
Step 5: Egg Wash
In another bowl, beat one egg with a splash of water to create your egg wash. Using a pastry brush, lightly brush the edges of two corners of each pastry square. This egg wash acts as a glue when you fold over one corner, ensuring the filling stays securely tucked inside while baking to golden perfection.
Step 6: Finish & Bake
Carefully fold the brushed corner over the filling, pressing lightly to seal. Brush the outside of the pastry with more egg wash, then sprinkle with flaky salt and any remaining seasoning mixture. Place your pastries on the prepared baking sheet and bake for 12-15 minutes, or until they are puffed up and a lovely golden brown.
Step 7: Cool
Once baked, remove the Flaky Ham and Cheese Puff Pastries from the oven and allow them to cool on a wire rack. This step is crucial as it helps maintain their flaky texture. After a few minutes, they’ll be just cool enough to handle and ready to serve as a delightful breakfast treat or appetizer!

Make Ahead Options
These Flaky Ham and Cheese Puff Pastries are ideal for meal prep, allowing you to savor fresh-baked goodness with minimal effort! You can assemble the pastries up to 24 hours in advance. Simply follow the recipe up to the point of baking, then cover the assembled pastries with plastic wrap and refrigerate. To maintain their flaky texture, be sure to wrap them snugly and avoid moisture. When you’re ready to enjoy, preheat your oven and bake the pastries without thawing them, adding an extra 2-3 minutes to the baking time if they are still cold. This way, you get delicious, golden-brown pastries that taste just as fresh as if you made them that morning!

Flaky Ham and Cheese Puff Pastries Recipe FAQs
How do I choose the right puff pastry?
Absolutely! For the best results, I recommend using high-quality brands like Pepperidge Farm or Dufour. These brands create flakier and more flavorful pastries due to their butter content and preparation methods. Always check the expiry date and packaging to ensure freshness.
How should I store leftovers?
After enjoying your flaky ham and cheese puff pastries, let them cool completely. Store them in an airtight container in the fridge, where they’ll stay fresh for up to 5 days. For longer storage, individually wrap each pastry in plastic wrap and place them in a freezer bag; they can remain frozen for up to 3 months!
Can I freeze the puff pastries before baking?
Yes, you can absolutely freeze them! Prepare the flaky ham and cheese puff pastries as directed, but before baking, individually wrap each one in plastic wrap and place them in a freezer-safe container. When you’re ready to enjoy them, bake directly from frozen at 350°F (175°C) for 15-20 minutes, or until golden and heated through.
What if my pastries leak filling while baking?
Oh no! If your pastries are leaking, it’s usually due to not sealing the edges properly. Make sure to egg wash all edges thoroughly before folding and press firmly to seal. If you find the filling is too full, next time, try using a bit less filling, which will help keep everything intact during baking!
Are these pastries safe for pets?
Great question! While ham is generally safe for dogs in small amounts, the spices and fats in this recipe could upset their stomachs. Additionally, cheese can cause digestive issues for some pets, especially if they are lactose intolerant. Always consult your veterinarian before sharing human food with your furry friends.
Can I modify the recipe for dietary restrictions?
Very! If you have dietary restrictions, consider using gluten-free puff pastry and a dairy-free cheese substitute to make these flaky ham and cheese puff pastries suitable for your needs. You can also leave out the spices that may trigger allergies or sensitivities, making it customizable for a variety of diets.
