How to Make Fastest Puff Pastry Chicken Appetizer Recipe
Step 1: Preheat Your Oven
Start by heating your oven to 200°C (400°F). Line a baking sheet with parchment paper to make cleanup a breeze and prevent the pastry from sticking. Preheating your oven ensures the pastry gets perfectly crisp and golden.
Step 2: Prepare the First Pastry Layer
Unroll one sheet of puff pastry onto your prepared baking sheet. This forms the base of your appetizer, so take a moment to smooth it out gently and make sure it covers the area evenly.
Step 3: Spread the Mustard
Using a spoon or a knife, spread 3 to 4 teaspoons of mustard evenly over the pastry, leaving a small border around the edges. This layer adds a wonderful sharpness that contrasts beautifully with the creamy mozzarella.
Step 4: Layer the Fillings
Sprinkle half of the grated mozzarella cheese evenly over the mustard, then scatter half of the chopped cooked chicken across the cheese. The cheese will melt and bind the filling, while the chicken adds a comforting, savory heartiness.
Step 5: Add Fresh Dill
Sprinkle half of the finely chopped fresh dill over the chicken. The dill brings a burst of fresh, herbal brightness that lifts the richness of the other ingredients.
Step 6: Top with Second Pastry Sheet
Place the second puff pastry sheet gently on top of your layered filling. Press down lightly around the edges to seal everything together. This top layer will puff up into a beautifully golden cover during baking.
Step 7: Brush with Egg Wash
Using a pastry brush, coat the top layer with the beaten egg. This step is key to achieving a shiny, golden crust that’s as visually appealing as it is delicious.
Step 8: Score the Pastry
Carefully score the top of the pastry into squares or rectangles with a sharp knife. This lets steam escape during baking and makes it easy to slice after cooking without squashing those gorgeous layers.
Step 9: Bake to Perfection
Slide the baking sheet into your preheated oven and bake for 20 to 25 minutes, or until the puff pastry has puffed up nicely and is golden brown all over. The smell wafting from your oven will be simply irresistible!
Step 10: Slice and Serve
Allow the baked puff pastry chicken to cool for 5 minutes before slicing along your scored lines. Serve warm, ideally with a side of ketchup for dipping, letting everyone personalize each bite.
How to Serve Fastest Puff Pastry Chicken Appetizer Recipe

Garnishes
A sprinkle of fresh dill or a light dusting of paprika can turn this classic appetizer into something quite special. Adding a few lemon zest shavings can also brighten the plate visually and flavor-wise.
Side Dishes
This appetizer pairs beautifully with a simple garden salad dressed in light vinaigrette or a bowl of crisp vegetable sticks. These fresh sides balance the richness of the puff pastry and chicken, creating a well-rounded snack or starter.
Creative Ways to Present
Serve the puff pastry appetizers on a rustic wooden board or a vibrant platter with small bowls of ketchup, mustard, or even a creamy herb dip. For a party, you can skewer small squares with toothpicks for effortless finger food styling.
Make Ahead and Storage
Storing Leftovers
Leftover puff pastry chicken can be stored in an airtight container in the refrigerator for up to 3 days. Keep the pieces separated by parchment paper to avoid sogginess, and reheat gently to keep the pastry crisp.
Freezing
If you want to prepare in advance, you can freeze the assembled but unbaked pastry wrapped tightly in plastic wrap and foil. Freeze for up to 2 months, then bake directly from frozen, adding a few extra minutes to the baking time.
Reheating
To reheat leftovers, warm them in a preheated oven at 180°C (350°F) for 10-12 minutes. This helps refresh the puff pastry’s crispness and warms the filling without drying it out—microwaving is not recommended here as it will make the pastry soggy.
FAQs
Can I use shredded chicken instead of chopped chicken?
Absolutely! Shredded chicken works wonderfully and can even create a more uniform filling. Just make sure it’s well-drained so the pastry doesn’t get soggy.
Is it okay to substitute mozzarella with another cheese?
Yes, you can swap mozzarella for cheeses like cheddar or gouda for a different flavor profile. Just keep in mind mozzarella’s mildness and meltability is part of what makes this recipe so comforting.
Can I make this recipe vegetarian?
Definitely! You can replace the chicken with sautéed mushrooms, roasted vegetables, or even a mix of spinach and feta to keep things tasty and suitable for vegetarians.
What if I don’t have fresh dill? Can I use dried herbs?
Fresh dill really brightens the dish, but if you only have dried herbs, use about one-third the amount and sprinkle it over the chicken. Fresh herbs provide the best flavor and aroma, though.
How do I prevent the pastry from getting soggy?
Spreading the mustard and cheese evenly helps create a barrier, and scoring the pastry allows steam to escape. Also, make sure the chicken isn’t too wet before adding it to the pastry.
