Chicken Stromboli Recipe: Flaky Pastry With Savory Cheese and Herb Filling

This stromboli delivers on the promise of flaky pastry wrapped around a hearty filling every time.

I developed this method after testing multiple dough recipes and fillings, focusing on achieving that perfect golden crust that shatters with each bite. The key is using store-bought puff pastry for guaranteed flaky layers without the fuss of homemade dough.

The filling combines tender chicken, melted cheese, and fresh herbs that create a savory center. Each slice reveals those beautiful layers while keeping the filling perfectly contained.

Baking at high heat ensures the pastry puffs and browns beautifully. The result is a meal that looks impressive but comes together with surprising simplicity.

Ingredients for Chicken Stromboli

Store-bought puff pastry meets tender chicken and melted cheeses for a foolproof stromboli.

The puff pastry is non-negotiable for that guaranteed flaky texture. Pepperidge Farm is the most reliable brand at standard grocery stores—look for it in the freezer aisle near the pie crusts. For the cheeses, Boar’s Head Provolone slices melt beautifully, and Sargento mozzarella shreds have consistent quality. The chicken should be uniformly diced (about 1/2-inch pieces) to ensure even cooking throughout the filling.

No provolone? Havarti or Swiss melt just as well. Fresh spinach can be swapped for frozen (thaw and squeeze out all moisture first). If you’re skipping the chicken, diced bell peppers and mushrooms add great texture. The Dijon mustard adds a subtle tang—whole grain mustard works too. For extra richness, add a layer of ricotta cheese before the other fillings.

Assemble the stromboli just before baking for best results. Leftovers keep 3-4 days in the fridge and reheat well in a 350°F oven for 10-12 minutes. The puff pastry is best used within 1 day of thawing—don’t refreeze it once thawed.

Step-by-Step Instructions for Chicken Stromboli

Master the technique for achieving golden, flaky layers with a rich, cheesy filling.

Step 1: Prepare the Chicken and Herb Filling

Heat the 2 tbsp olive oil in a large skillet over medium-high heat. Add the 1.5 lb boneless skinless chicken breasts, diced into small pieces, and season with ½ tsp kosher salt and 0.5 tsp ground black pepper. Sauté for 6-8 minutes until the chicken is cooked through and lightly browned.

Reduce heat to medium, then stir in the 3 cloves garlic cloves (minced), 2 cups fresh spinach leaves (chopped and drained), 0.25 cup fresh basil leaves (chopped), 1 tbsp Dijon mustard, and 1 tsp dried oregano. Cook for 2-3 minutes until the spinach wilts and the mixture is fragrant. Remove from heat and set aside to cool slightly.

Step 2: Roll Out the Puff Pastry

Unfold the 2 sheets puff pastry sheets on a lightly floured surface. Roll each sheet into a 12×10-inch rectangle, ensuring an even thickness. This creates the foundation for a sturdy, flaky crust that will hold the filling without tearing.

Using a sharp knife or pizza cutter, make shallow diagonal cuts about 1 inch apart along the long edges of each sheet, stopping ½ inch from the center. These cuts will create a decorative, lattice-like effect while ensuring the pastry bakes evenly.

Step 3: Layer the Cheese and Chicken Filling

Spread 0.5 cup Parmesan cheese evenly over the center of each puff pastry sheet, leaving a 1-inch border around the edges. Distribute the cooked chicken mixture evenly on top of the Parmesan, then layer with 8 slices provolone cheese slices and 1.5 cups mozzarella cheese.

Fold the uncut edges of the pastry over the filling, overlapping slightly to seal. Braid the cut strips over the top, alternating sides to create a tight, secure lattice. Press the edges firmly to prevent any filling from escaping during baking.

Step 4: Bake to Golden Perfection

Preheat the oven to 400°F. Transfer the stromboli to a parchment-lined baking sheet. Brush the top and sides with the 1 whole large egg (beaten) to achieve a deep, golden-brown finish.

Bake for 25-30 minutes until the pastry is puffed and golden brown. If the top browns too quickly, tent loosely with aluminum foil. Remove from the oven and let rest for 5 minutes before slicing to allow the filling to set.

Serving Suggestions for Leftovers

Plating for Impact

Slice each stromboli diagonally into 1.5-inch pieces to showcase the beautiful layers. Arrange on a wooden board or slate platter for that rustic Italian trattoria feel. The golden pastry against dark wood creates stunning contrast.

Dipping Sauces

Serve with warm marinara sauce on the side for dipping—I use Rao’s Homemade. A creamy ranch dressing balances the richness perfectly. Offer pesto for herb lovers, or spicy arrabbiata for heat seekers.

Side Pairings

A simple mixed greens salad with balsamic vinaigrette cuts through the richness. I love roasted Brussels sprouts with a sprinkle of Parmesan. For heartier meals, add garlic mashed potatoes or minestrone soup. 🥗

Beverage Matches

A crisp Pinot Grigio from Italy complements the herbs beautifully. For beer, try a light lager like Peroni. Non-alcoholic? Sparkling water with lemon or iced tea with mint works wonderfully.

Serving Temperature

This dish is best served warm, straight from the oven. If making ahead, reheat slices at 350°F for 8-10 minutes to restore crispness. I always let it rest 5 minutes before slicing to prevent cheese pull-out.

Portion Sizing

Each stromboli yields 6-8 slices. For a meal, serve 2 slices per person with sides. For appetizers, cut into 1-inch pieces and serve with toothpicks. The puff pastry stays flaky for up to 2 hours at room temperature. 💛
