Ingredients
The magic of these puff pastries lies in a few carefully chosen components. Ripe plum tomatoes provide natural sweetness and acidity, while fresh mozzarella delivers a melt‑in‑your‑mouth creaminess. A splash of extra‑virgin olive oil and a pinch of sea salt amplify the flavors, and the puff pastry sheets give you that coveted airy crunch. Fresh basil adds a fragrant lift at the finish, turning a simple snack into a celebration of summer flavors.
Pastry & Filling
- 2 sheets frozen puff pastry, thawed
- 4 medium plum tomatoes, diced
- 8 oz fresh mozzarella, torn into small pieces
Seasoning & Aromatics
- 2 tbsp extra‑virgin olive oil
- 1 tsp sea salt
- ½ tsp freshly ground black pepper
- ¼ tsp crushed red‑pepper flakes (optional)
- 2 tbsp fresh basil, finely chopped
Finishing Touches
- 1 egg, lightly beaten (for egg wash)
- 1 tbsp grated Parmesan (optional, for garnish)
These ingredients work together to create a layered taste experience. The tomatoes release a little juice that keeps the mozzarella moist while baking, and the olive oil ensures the pastry stays crisp. Salt and pepper enhance the natural sweetness of the tomatoes, whereas red‑pepper flakes add a subtle heat for those who enjoy a gentle kick. Finally, the egg wash gives the pastries a glossy, golden finish, and a sprinkle of Parmesan adds an extra umami note that rounds out the flavor profile.
Step-by-Step Instructions

Preparing the Filling
In a medium bowl, combine the diced tomatoes, torn mozzarella, olive oil, sea salt, black pepper, and optional red‑pepper flakes. Toss gently until the cheese is lightly coated and the tomatoes are evenly seasoned. Let the mixture sit for 5 minutes; this allows the tomatoes to release a little of their juices, creating a naturally moist filling that will keep the pastry from drying out.
Assembling the Pastries
- Roll the pastry. On a lightly floured surface, unfold one sheet of puff pastry and roll it to a smooth 12‑inch square. This extra roll eliminates any seam lines and ensures an even thickness for uniform puffing.
- Cut into squares. Using a sharp knife or pizza cutter, divide the sheet into eight equal 3‑inch squares. Keep the squares covered with a clean kitchen towel to prevent them from drying out while you work on the remaining sheet.
- Place the filling. Spoon about 1½ tablespoons of the tomato‑mozzarella mixture onto the center of each square. Be careful not to overfill; too much moisture can make the pastry soggy.
- Fold and seal. Bring opposite corners together to form a triangle, pressing the edges gently with your fingertips. Then, use a fork to crimp the sealed edges, creating a decorative pattern and ensuring the filling stays inside.
- Apply egg wash. Brush the top of each pastry with the beaten egg. This step is crucial for achieving a glossy, deep‑gold color once baked.
- Add final garnish. Sprinkle a light dusting of grated Parmesan over each pastry, if using, and scatter a few fresh basil leaves on top for a burst of color and aroma.
Baking to Perfection
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Arrange the pastries on the sheet, leaving a small gap between each to allow steam to escape. Bake for 18‑22 minutes, or until the puff pastry is puffed, golden‑brown, and the cheese inside is melted and slightly bubbling. The visual cue of a deep amber hue signals they are ready. Remove from the oven and let them rest for 2 minutes before transferring to a wire rack; this prevents the bottoms from becoming soggy.
Tips & Tricks
Perfecting the Recipe
Dry the tomatoes. After dicing, pat the tomato pieces with paper towels. Excess moisture can make the pastry soggy, while a dry surface promotes a crisp interior.
Chill the assembled pastries. Place the formed pastries in the refrigerator for 10‑15 minutes before baking. Cold dough expands more dramatically in the oven, yielding a higher lift.
Use a light hand with the egg wash. Too much egg can cause the edges to brown too quickly, while a thin coat ensures an even sheen.
Flavor Enhancements
For an extra layer of complexity, drizzle a teaspoon of aged balsamic reduction over each pastry just before serving. A pinch of smoked paprika in the filling adds a subtle earthiness, and a sprinkle of toasted pine nuts provides a delightful crunch.
Common Mistakes to Avoid
Avoid overfilling; excess filling leaks during baking and creates a soggy base. Also, don’t skip the preheating step—an oven that isn’t fully hot will prevent the pastry from puffing properly, resulting in a dense texture.
Pro Tips
Work quickly. Puff pastry is sensitive to heat; the longer it sits at room temperature, the more likely it is to become buttery and lose its lift.
Use a pastry brush. A silicone brush distributes the egg wash evenly without tearing the delicate dough.
Rotate the pan halfway. Oven hotspots can cause uneven browning; a simple 180° turn at the 10‑minute mark ensures uniform color.
Variations
Ingredient Swaps
Swap fresh mozzarella for creamy burrata for an ultra‑rich center, or use sun‑dried tomatoes instead of fresh for a deeper, concentrated flavor. Adding thinly sliced prosciutto before folding introduces a salty, meaty dimension that pairs beautifully with the sweet tomatoes.
Dietary Adjustments
For a gluten‑free version, replace the puff pastry with a certified gluten‑free alternative or use a homemade almond‑flour pastry. Vegans can substitute dairy‑free mozzarella and use a plant‑based egg wash made from soy milk mixed with a dash of turmeric for color.
Serving Suggestions
Serve these pastries alongside a simple arugula salad dressed with lemon vinaigrette, or pair them with a chilled glass of prosecco for a festive brunch. They also make a delightful appetizer on a cheese board, nestled between olives, marinated artichokes, and a selection of cured meats.
Storage Info
Leftover Storage
Allow any leftovers to cool completely, then place them in a single layer inside an airtight container. Store in the refrigerator for up to 3 days. For longer keeping, wrap each pastry individually in plastic wrap, then seal them in a freezer‑safe bag; they’ll maintain quality for up to 2 months.
Reheating Instructions
Reheat refrigerated pastries in a preheated 350°F (175°C) oven for 8‑10 minutes, or until the pastry regains its crispness. If reheating from frozen, add an extra 5‑7 minutes. A quick microwave burst can warm the interior but will soften the crust, so the oven method is preferred for best texture.
