Pro Tips for Making the Best Italian Sub Squares
To ensure that your Italian Sub Squares come out perfectly every time, keep these expert tips in mind:
1. Use High-Quality Deli Meats and Cheeses
Since this dish relies heavily on the flavors of its ingredients, opt for freshly sliced, high-quality deli meats and cheeses. Avoid pre-packaged options with added preservatives, as they may not melt or taste as good when baked.
2. Press and Seal the Crescent Roll Dough
Crescent roll dough is a fantastic shortcut, but its perforated edges can cause issues if not sealed properly. When pressing the dough into your baking dish, use your fingers or a rolling pin to seal any seams to create a uniform base. This prevents the filling from leaking out during baking.
3. Brush the Top with Egg Wash or Butter
For a beautiful golden-brown crust, don’t skip the egg wash or melted butter. This step enhances both the appearance and the texture of the baked squares, making them look as appetizing as they taste.
4. Let It Cool Before Slicing
It’s tempting to dig in right away, but allowing the sub squares to cool for at least 5-10 minutes before slicing helps everything set properly. This makes for cleaner cuts and prevents the layers from falling apart.
Creative Variations to Try
1. Spicy Italian Sub Squares
For those who love a little heat, add sliced jalapeños, spicy giardiniera, or crushed red pepper flakes between the layers. You can also use spicy pepper jack cheese for an extra kick.
2. Mediterranean-Inspired Sub Squares
Give this dish a Mediterranean twist by adding ingredients like kalamata olives, sun-dried tomatoes, and feta cheese. Swap the traditional meats for thinly sliced prosciutto and capicola for an even more authentic flavor.
3. Vegetarian Sub Squares
Eliminate the deli meats and load up on roasted vegetables instead. Try layers of grilled eggplant, zucchini, roasted red peppers, caramelized onions, and spinach, paired with a mix of provolone and mozzarella.
4. Low-Carb or Keto-Friendly Version
If you’re following a low-carb diet, replace the crescent roll dough with a keto-friendly alternative, such as almond flour fathead dough. Another option is to make lettuce wraps using the same ingredients while skipping the baking step.
Serving Suggestions: What to Pair with Italian Sub Squares
While Italian Sub Squares are delicious on their own, pairing them with complementary sides enhances the meal. Here are a few perfect matches:
1. Classic Italian Side Salad
A fresh salad with crisp lettuce, cherry tomatoes, red onions, olives, and a tangy vinaigrette balances out the richness of the sub squares.
2. Warm Tomato Soup
Nothing complements a cheesy baked dish better than a bowl of warm tomato soup. The acidity of the tomatoes cuts through the richness of the cheese, creating a comforting combination.
3. Garlic Parmesan Fries
Crispy garlic parmesan fries add a satisfying crunch to your plate and pair well with the Italian flavors in the sub squares.
4. Marinated Antipasto Platter
For a true Italian-inspired spread, serve a platter of marinated olives, artichoke hearts, fresh mozzarella balls, and cured meats alongside your sub squares.
Frequently Asked Questions (FAQs)
1. Can I Make Italian Sub Squares Ahead of Time?
Yes! You can assemble the dish up to 24 hours in advance and refrigerate it until you’re ready to bake. Just be sure to cover it tightly with plastic wrap to keep the dough from drying out.
2. How Do I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm them in the oven at 350°F until heated through to maintain the crispy texture.
3. Can I Freeze Italian Sub Squares?
Absolutely! Wrap individual squares in aluminum foil and freeze for up to 2 months. When ready to eat, reheat them directly from frozen in a 350°F oven until warm and crisp.
4. Can I Use Puff Pastry Instead of Crescent Roll Dough?
Yes! Puff pastry creates a flakier, more delicate texture compared to crescent roll dough. Just be sure to thaw it properly before use and adjust the baking time if needed.
5. What Are the Best Cheese Substitutes?
If you want to switch up the cheese, try pepper jack for spice, cheddar for sharpness, or Swiss for a milder flavor. Combining different cheeses can also create a more complex taste.
6. What’s the Best Way to Slice the Squares?
For clean, even cuts, use a sharp serrated knife or a pizza cutter. Letting the dish cool before slicing will also prevent the layers from shifting.
