Air Fryer Puff Pastry Bites
Why this recipe works
- Fast pastry snack: Ready-made puff pastry and a short air-fryer cook time keep the recipe practical for last-minute serving.
- Crisp, flaky finish: Keeping the pastry in a single layer allows hot air to circulate, helping the bites puff evenly and brown well.
- Balanced savoury flavour: Sharp cheddar brings richness, Dijon adds gentle tang, and sesame seeds give the tops a nutty savoury finish.

Texture tips
- Keep the pastry cold: Cold pastry puffs more cleanly and is easier to cut and seal without compressing the layers.
- Seal lightly: Press the edges just enough to hold the filling in place; heavy pressure can flatten the pastry and limit the rise.
- Cook in batches: Arrange the bites in a single layer so the air fryer can brown the pastry instead of steaming it.
Timing notes
- Serve warm: The bites are at their best shortly after cooking, when the pastry is crisp and the cheese is soft.
- Let the filling settle: A brief stand after air frying makes the melted cheese less molten and easier to eat.
Ingredient notes
- Use all-butter pastry if possible: All-butter puff pastry gives a richer flavour and a cleaner, flakier texture than many standard versions.
- Choose a strong cheese: Mature cheddar gives enough sharpness to stand out against the buttery pastry and mild mustard.
Make-ahead tips
- Refresh before serving: Reheat chilled bites in the air fryer at 180°C (355°F) for a few minutes until piping hot and crisp again.
- Best freshly cooked: They can be refrigerated after cooling, but the pastry texture is lightest and crispest on the day they are air fried.

Ingredients
Instructions
- Unroll the puff pastry onto a board and cut it into 20 equal squares. Spread a very thin smear of dijon mustard over half the squares, keeping a small border clear.
- Divide the cheddar cheese over the mustard-topped squares, then top with the remaining squares and press the edges lightly to seal. Beat the egg and brush a little over the tops, then sprinkle with sesame seeds.
- Air fry at 190°C (375°F) for 8 to 10 minutes until well puffed and deeply golden, working in batches so the bites are in a single layer. Leave to stand for 2 minutes before serving so the filling is less molten.
Recipe notes
Tips
- For neat layers and maximum puff, keep the pastry cold and avoid pressing too hard when sealing the squares.
- If your air fryer runs hot, check at 8 minutes; the cheese filling can make the pastry brown quickly.
Substitutions
- Replace Cheddar cheese with Gruyere cheese for a nuttier, more mellow filling.
- Replace Dijon mustard with whole-grain mustard for a milder heat and a coarser texture.
Storage
- Refrigerate up to 2 days
- Cool completely, then refrigerate airtight. Reheat in the air fryer at 180°C (355°F) for 3 to 4 minutes until piping hot and crisp.
