Philly Cheesesteak Puff Pastry Stromboli Tips, FAQ & printable recipe

Tips for success

To achieve an even, professional-looking golden finish on your puff pastry, brush the surface lightly with an egg wash before baking. Simply whisk one egg with a tablespoon of water and apply it with a pastry brush.

This adds a beautiful sheen and helps the pastry become extra crispy and rich in color. You can also sprinkle a little extra steak seasoning or some dried herbs on top of the egg wash for added flavor and visual appeal before the stromboli enters the oven.

If you find that the cheese is browning too quickly before the center of the pastry is fully cooked, you can loosely tent the stromboli with a piece of aluminum foil for the last few minutes of baking.

This protects the top layer from burning while allowing the pastry to finish cooking through. Always monitor the oven closely during the final five minutes, as puff pastry can go from perfectly golden to dark brown very quickly depending on the specific heat distribution of your oven.

Variations

• Vegetable Cheesesteak: Add sautéed bell peppers and onions to the steak filling for a classic Philly-style twist. Ensure the vegetables are cooked until tender and moisture-free before adding them to the pastry.
• Spicy Pepper Jack: Replace the mozzarella with shredded pepper jack cheese and add a few slices of pickled jalapeños to the filling for a spicy kick that pairs perfectly with the savory beef.

Storage and make-ahead

Fridge

Keep in an airtight container for up to 3 days. Allow to cool completely before covering to prevent the pastry from becoming soggy.

Freezer

Wrap tightly in plastic wrap and then aluminum foil. Freeze for up to 1 month. Thaw in the refrigerator before reheating.

Reheat

Reheat in a preheated oven at 350°F (175°C) for 10-15 minutes until the pastry is crisp and the center is heated through.

Store any leftover stromboli in an airtight container. Cool the leftovers at room temperature for no more than 2 hours before moving them into the refrigerator. This ensures food safety and prevents the pastry from becoming overly soft. If you do not plan to eat the leftovers within a few days, it is best to freeze them immediately after they have cooled to ensure the best quality and flavor for later consumption.

You can prepare the filling ahead of time and keep it in the refrigerator for up to 24 hours. However, for the best results, assemble the stromboli just before you are ready to bake it. Puff pastry can become sticky and difficult to work with if it sits for too long after being filled. If you need to save time, have your beef seared and your cheese shredded the day before, so you only have to roll, fill, and bake when you are ready to serve.

Serving ideas

Serve the stromboli immediately after its short resting period to enjoy the contrast between the hot, gooey interior and the crisp, flaky exterior. A simple side salad with a bright vinaigrette provides a refreshing balance to the richness of the pastry and cheese, making for a well-rounded meal.

You can also offer a side of warm marinara or a creamy dipping sauce, though the dish is flavorful enough to stand perfectly on its own without any additional accompaniments for your diners to enjoy.

When slicing, use a serrated bread knife and a gentle sawing motion to cut through the puff pastry without crushing it. Aim for thick slices to ensure each portion holds its shape and contains a generous amount of the steak and cheese filling.

Arrange the slices on a warm serving platter to keep them at the ideal temperature for as long as possible. Serving this as an appetizer or a main course makes it a versatile addition to any menu, especially when you are looking for something impressive.

Philly Cheesesteak Puff Pastry Stromboli

Prep 15 minCook 25 minRest 5 minTotal 45 minServes 4

Ingredients

• 1 lb thinly sliced beef steak
• 1 sheet puff pastry, thawed
• 2 cups shredded mozzarella cheese
• 1 tbsp steak seasoning

Instructions

1. Heat a large skillet over medium-high heat. Add the thinly sliced beef steak and season with the steak seasoning. Sauté the meat until it is browned and cooked through, reaching an internal temperature of 145°F (63°C). Remove the pan from the heat and let the meat rest for at least 3 minutes before proceeding.
2. Preheat your oven to 400°F (200°C). Roll out the puff pastry sheet on a piece of parchment paper. Spread the cooked steak evenly over the center of the pastry, then top with the shredded mozzarella cheese. Roll the pastry tightly around the filling, pinching the edges closed to seal the stromboli completely.
3. Place the assembled stromboli on a baking sheet. Bake in the preheated oven for 20 to 25 minutes, or until the puff pastry is golden brown and the cheese is melted and bubbling. Remove from the oven and allow it to rest for a few minutes before slicing into thick, hearty portions to serve.
