Ingredients
- 2 sheets (17.3 ounces total) frozen puff pastry, thawed
- 1 tablespoon olive oil
- 1/2 cup finely diced red onion
- 1/4 cup finely diced green bell pepper (optional, for added flavor and color)
- 1/2 teaspoon dried oregano
- 1/4 teaspoon garlic powder
- Pinch of red pepper flakes (optional, for a little kick)
- 4 ounces thinly sliced provolone cheese
- 4 ounces thinly sliced mozzarella cheese (fresh or low-moisture, part-skim)
- 4 ounces thinly sliced deli ham (such as Black Forest or Italian-style ham)
- 4 ounces thinly sliced Genoa salami
- 4 ounces thinly sliced pepperoni
- 1 large egg, beaten (for egg wash)
- 1 tablespoon water (for egg wash)
- Sesame seeds or poppy seeds (optional, for topping)
- Marinara sauce or Italian dressing, for serving
Instructions
- Preheat your oven to 400°F (200°C). Line a large baking sheet (approximately 13×18 inches) with parchment paper.
- Unroll one sheet of thawed puff pastry onto the prepared baking sheet. If the pastry is folded, gently unfold it and use a rolling pin to lightly smooth out any creases. Try to keep it as rectangular as possible.
- In a small skillet over medium heat, add the olive oil. Once hot, add the finely diced red onion and green bell pepper (if using). Sauté for 5-7 minutes, or until softened and translucent. Stir in the dried oregano, garlic powder, and red pepper flakes (if using). Remove from heat and let cool slightly.
- Layer the ingredients evenly over the first puff pastry sheet, leaving about a 1/2-inch border around the edges. Start with half of the provolone cheese, followed by half of the mozzarella cheese.
- Next, layer all of the deli ham, then all of the Genoa salami, and then all of the pepperoni.
- Sprinkle the cooled sautéed onion and bell pepper mixture evenly over the meats.
- Top with the remaining half of the mozzarella cheese, followed by the remaining half of the provolone cheese.
- Carefully unroll the second sheet of thawed puff pastry and place it directly over the layered fillings. Gently press down on the edges of the top pastry sheet to seal it with the bottom sheet, creating a complete sandwich. You can use a fork to crimp the edges together for a decorative seal.
- In a small bowl, whisk together the beaten egg and water to create an egg wash. Brush the entire top surface of the puff pastry with the egg wash. This will give it a beautiful golden-brown color and a lovely sheen.
- If desired, sprinkle sesame seeds or poppy seeds evenly over the top of the egg-washed pastry.
- Using a sharp knife, gently score the top of the puff pastry into 12-16 squares or desired serving sizes. Do not cut all the way through the pastry; just score the top layer. This will make it easier to cut after baking and help steam escape.
- Bake for 25-35 minutes, or until the puff pastry is deeply golden brown and puffed up, and the cheese is melted and bubbly. The pastry should look flaky and cooked through.
- Remove the baking sheet from the oven and let the Italian Sub Squares cool for 5-10 minutes before cutting all the way through the scored lines.
- Serve warm or at room temperature with marinara sauce for dipping, or a side of Italian dressing.
Cooking Tips and Variations
Achieving the perfect Italian Sub Squares is all about paying attention to a few key details and embracing creativity. For starters, when working with puff pastry, remember that
keeping it cold is paramount. If your pastry gets too warm, it becomes sticky and loses its delicate layers. Work quickly, and if it starts to feel soft, pop it back into the refrigerator for 10-15 minutes. A light dusting of flour on your work surface can also help prevent sticking, but use it sparingly to avoid toughening the pastry.
For the fillings,
don’t skimp on quality. High-quality deli meats make a noticeable difference. Look for thinly sliced varieties of ham, salami, and pepperoni. Prosciutto or mortadella can also be fantastic additions. For cheeses, a good melting cheese is essential. Provolone and mozzarella are classics, but fontina, Gruyère, or even a sharp white cheddar can add interesting flavor profiles. If using fresh mozzarella, pat it dry thoroughly to prevent excess moisture from making the pastry soggy.
When assembling,
avoid overfilling. While it’s tempting to pack in as much as possible, too many layers can make it difficult for the pastry to cook through evenly and seal properly. Aim for even distribution of ingredients to ensure every bite is balanced. Pressing down firmly but gently on the top pastry sheet to seal the edges is crucial; a fork crimp adds both security and a nice decorative touch.
One clever tip for even baking and preventing the top from browning too quickly is to
place a sheet of parchment paper on top of the squares during the first 15-20 minutes of baking. You can even place another baking sheet on top of the parchment paper to gently weigh it down, encouraging flatter, more even layers, especially if your puff pastry tends to puff up excessively in the center. Remove the top parchment and baking sheet for the last 10-15 minutes to allow the pastry to achieve that beautiful golden finish.
Now for the fun part:
variations! The beauty of this recipe is its adaptability. For a vegetarian option, load it up with roasted red peppers, sautéed mushrooms, spinach (squeezed dry!), sun-dried tomatoes, and a mix of provolone and feta cheese. You could even add some pesto or a balsamic glaze drizzle inside. For a spicier kick, add pickled jalapeños or banana peppers to the filling, or a sprinkle of extra red pepper flakes.
Consider adding a
layer of finely chopped black olives or artichoke hearts for a briny, tangy element. A thin layer of pizza sauce or marinara on the bottom pastry sheet (before adding other fillings) can also enhance the “sub” experience, but be mindful not to add too much moisture. For a more robust flavor, brush the inside of the puff pastry with a thin layer of garlic butter before layering the ingredients.
Finally, for a different shape, instead of squares, you can
slice the baked pastry into strips or triangles, making them even more appetizer-friendly. These Italian Sub Squares are a fantastic canvas for your culinary creativity, so feel free to experiment with your favorite Italian-inspired ingredients!
Storage and Reheating
Italian Sub Squares are best enjoyed fresh out of the oven when the pastry is at its flakiest and the cheese is delightfully gooey. However, they store and reheat surprisingly well, making them excellent for meal prepping or enjoying leftovers.
To store any leftover baked Italian Sub Squares, first ensure they have cooled completely to room temperature. This is crucial to prevent condensation from making the pastry soggy. Once cool, place them in an airtight container. You can layer them between sheets of parchment paper if stacking multiple pieces to prevent them from sticking together. Store them in the refrigerator for up to 3-4 days.
For reheating, the oven or a toaster oven is your best friend for achieving the closest texture to freshly baked. Preheat your oven or toaster oven to 350°F (175°C). Place the squares directly on a baking sheet (you can line it with parchment paper if you prefer). Reheat for 10-15 minutes, or until the pastry is crisp again and the cheese is melted and warm throughout. Keep an eye on them to prevent over-browning. The microwave is generally not recommended for reheating these squares, as it tends to make the puff pastry soft and chewy rather than flaky.
If you wish to make these ahead of time, you can assemble the squares completely, brush with egg wash, and score them, but do not bake. Cover the unbaked squares tightly with plastic wrap and refrigerate for up to 24 hours. When ready to bake, remove them from the refrigerator about 15-20 minutes before baking to allow them to come closer to room temperature, then bake as directed in the recipe, possibly adding a few extra minutes to the baking time to ensure they are cooked through.
Frequently Asked Questions
Can I use different types of meat or cheese?
Absolutely! This recipe is incredibly versatile. Feel free to swap out the ham, salami, or pepperoni for other Italian deli meats like mortadella, prosciutto, or even thinly sliced turkey or chicken for a lighter option. For cheeses, provolone and mozzarella are classic, but fontina, Gruyère, or even a sharp white cheddar can add a delicious twist. Just ensure the cheeses melt well.
Can I add vegetables to the Italian Sub Squares?
Yes, adding vegetables is a great way to enhance flavor and nutrition! Beyond the suggested red onion and bell pepper, consider adding finely chopped sun-dried tomatoes (patted dry), sautéed mushrooms, spinach (wring out all excess moisture), or even pickled banana peppers for a tangy kick. Just be mindful not to add too many watery vegetables, as this can make the pastry soggy.
How do I prevent the puff pastry from becoming soggy?
Several factors help prevent soggy pastry. First, ensure any vegetables you add are cooked and excess moisture is removed (e.g., wring out spinach). If using fresh mozzarella, pat it very dry. Avoid overfilling the squares, as too many layers can trap moisture. Finally, always cool the baked squares completely before storing them in an airtight container to prevent condensation.
Can these Italian Sub Squares be frozen?
While best fresh, you can freeze baked Italian Sub Squares. Allow them to cool completely, then wrap individual squares tightly in plastic wrap, followed by a layer of aluminum foil. Store in a freezer-safe bag or container for up to 1 month. To reheat, unwrap and bake from frozen in a preheated oven at 350°F (175°C) for 20-30 minutes, or until heated through and crisp.
