Preparing the Puff Pastry
If you are using frozen puff pastry, allow it to thaw according to the package instructions.
The pastry should be flexible enough to unfold without cracking, but it should still feel cool. Avoid leaving it at room temperature for too long because very warm puff pastry can become sticky and difficult to handle.
Lightly flour your work surface if needed and gently unfold the pastry.
If the sheet has become uneven, use a rolling pin to lightly smooth it. Do not roll it too thin because you want enough pastry layers to puff beautifully in the air fryer.
Preparing the Filling
Lay the ham slices flat and cut them into smaller pieces that will fit comfortably inside the pastry.
Place the shredded cheese in a bowl.
If you want an extra savory flavor, mix the cheese with a small amount of Italian seasoning and black pepper.
Dijon mustard is also optional but adds a nice tangy flavor. Spread only a thin layer over the pastry because too much mustard can make the pastry difficult to seal.
You can keep the filling simple with just ham and cheese, or add your favorite seasoning according to your taste.
Cutting the Pastry
Cut the puff pastry into approximately 6–8 equal rectangles or squares.
The exact size is up to you. Smaller pieces are perfect for appetizers, while larger rectangles work well for breakfast or lunch.
Place a small amount of ham in the center of each piece.
Add shredded cheese on top.
Do not overfill the pastry. It may be tempting to add lots of cheese, but excessive filling can escape during cooking and make the pastry harder to seal.
Leave a border around the edges.
Sealing the Pastry
Fold each piece of puff pastry over the filling.
You can create simple rectangular pockets by folding the pastry in half, or fold the corners toward the center for a different shape.
Press the edges firmly with your fingers.
For an extra secure seal, use the tines of a fork to gently press around the edges.
This also gives the pastries a nice decorative finish.
If any filling is sticking out around the edges, carefully push it back inside before sealing.
Making the Egg Wash
Crack one egg into a small bowl.
Add one tablespoon of water and whisk until combined.
This creates a simple egg wash that helps the puff pastry become shiny and beautifully golden during cooking.
Using a pastry brush, lightly brush the top of each pastry with the egg wash.
Try not to let large amounts of egg wash drip down the sides because it can interfere with the pastry layers puffing properly.
You can sprinkle a tiny amount of Italian seasoning or sesame seeds over the top if desired.
Preheating the Air Fryer
Preheat your air fryer to 375°F (190°C) for approximately 3–5 minutes.
Preheating helps the pastry begin cooking immediately and can encourage better puffing.
Lightly spray the air fryer basket with cooking spray if needed.
You can also use a piece of perforated parchment paper designed for air fryers. Make sure the parchment does not block the airflow completely.
Air Frying the Ham and Cheese Pastries
Place the prepared pastries into the air fryer basket in a single layer.
Leave some space between each piece.
Do not overcrowd the basket. Puff pastry needs room for the hot air to circulate around it.
Air fry at 375°F (190°C) for approximately 8–12 minutes, depending on the size of the pastries and your particular air fryer.
Start checking around the 8-minute mark.
The pastries are ready when they are puffed, crisp, and golden brown on top.
If they need additional color or crispness, continue cooking for another 1–2 minutes.
Air fryers can vary considerably, so the first batch is a good opportunity to learn how quickly your particular model cooks puff pastry.
Let Them Cool Slightly
Once the pastries are golden and crisp, carefully remove them from the air fryer.
Allow them to cool for approximately 3–5 minutes before serving.
The cheese inside will be extremely hot immediately after cooking.
A short resting time also makes the pastries easier to handle.
Tips for Crispy Puff Pastry
Keep the pastry cold
Cold puff pastry generally handles better and produces good flaky layers. If it becomes too soft while you are preparing the filling, place it in the refrigerator for a few minutes.
Do not overfill
Too much ham or cheese can cause the seams to open while cooking.
A moderate amount of filling gives you a better balance between crispy pastry and melted filling.
Seal the edges well
Press the edges firmly with your fingers and then use a fork if desired.
Leave space in the air fryer
Air circulation is important for achieving crisp pastry.
Cook in batches if necessary.
Watch the final minutes
Puff pastry can go from golden brown to overly dark relatively quickly, so keep an eye on it near the end of cooking.
Variations
There are many ways to change these pastries while keeping the basic recipe the same.
Ham and Swiss: Use Swiss cheese for a classic combination.
Ham and cheddar: Cheddar gives the pastries a stronger cheesy flavor.
Ham, cheese and mustard: Add a thin layer of Dijon mustard before adding the filling.
Ham and mozzarella: Mozzarella creates a deliciously stretchy center.
Turkey and cheese: Replace the ham with sliced turkey.
Cheese and spinach: Add a small amount of cooked, well-drained spinach with the cheese.
Pizza-style pastries: Add a little pizza seasoning and a small amount of tomato sauce for a different flavor.
What to Serve With Them
These puff pastries can be served on their own, but they also pair nicely with other foods.
For breakfast, serve them with scrambled eggs, fresh fruit, or a simple salad.
For lunch, pair them with tomato soup or a green salad.
For a party, arrange the smaller pastries on a serving platter with mustard or another dipping sauce.
They are also convenient for lunchboxes once completely cooled.
Storage and Reheating
Store leftover pastries in an airtight container in the refrigerator for up to 3 days.
For the best texture, reheat them in the air fryer rather than the microwave.
Air fry at 350°F (175°C) for 3–5 minutes, or until warmed through and crisp again.
The microwave can warm the filling quickly, but it may make the puff pastry softer.
You can also freeze the assembled, uncooked pastries. Place them on a tray until firm, then transfer them to a freezer-safe container or bag.
When ready to cook, they can generally be air fried from frozen, adding a few extra minutes to the cooking time. Check that the pastry is fully puffed and golden and that the filling is heated through.
Frequently Asked Questions
Can I use pre-cooked ham?
Yes. Sliced deli ham or leftover cooked ham both work well.
Can I make these ahead of time?
Yes. Assemble the pastries ahead of time and keep them refrigerated until you are ready to air fry them.
Why did my cheese leak out?
This usually happens when the pastries are overfilled or the edges are not sealed firmly enough. Leave a clean border around the filling and press the edges well.
Can I make them without egg wash?
Yes. Egg wash gives the pastry a shiny golden finish, but the pastries can still be cooked without it.
