- Thinly Sliced Salami (4 oz.) Adds a robust flavor; you can swap with any cured meat you like.
- Giardiniera Mix or Muffuletta Mix (1.5 cups, drained and patted dry) Contributes a tangy kick; chopped olives or capers can be a good replacement.
For the Topping
- Extra-Virgin Olive Oil (1 Tbsp.) Boosts flavor and aids browning; regular olive oil is also fine.

How to Make Italian Sub Squares
Preheat oven: Start by setting your oven to 375 °F (190 °C) and generously grease your baking pan with cooking spray or vegetable oil to ensure a perfect release.
First Layer: Roll out one tube of crescent dough into the prepared pan, making sure to press the seams together to seal the dough and create a sturdy base.
Layer Fillings: Evenly distribute half of the shredded Asiago cheese across the dough, followed by the mortadella, ham, provolone, salami, giardiniera mix, and top with the remaining Asiago.
Cover and Seal: Unroll the second tube of crescent dough and place it on top of the filling, sealing the edges well by pinching the seams and preventing any filling from escaping.
Prep for Baking: Brush the top layer of dough with extra-virgin olive oil, then sprinkle sesame seeds and dried oregano to create a beautiful, aromatic topping.
Bake: Place the pan in the oven and bake for about 30-35 minutes until the crust turns golden brown and flaky. Allow to cool for roughly 15 minutes before cutting into squares for serving.

Tips for the Best Italian Sub Squares
Layer Correctly: Ensure you follow the layering sequence for fillings to maintain balance, so every bite of your Italian Sub Squares is flavorful and satisfying.
Cool Before Cutting: Allow the squares to cool for about 15 minutes before slicing; this prevents the fillings from spilling out and ensures clean cuts.
Drain Thoroughly: Always drain giardiniera or muffuletta mixes well to avoid a soggy bottom; moisture will ruin the texture of your Italian Sub Squares.
Experiment Freely: Don t hesitate to customize fillings! Use your favorite cheeses and meats or try roasted vegetables for a meat-free twist.
Keep It Sealed: When placing the top layer of dough, pinch seams tightly to avoid leaks during baking, ensuring all those delightful flavors stay inside.
How to Store and Freeze Italian Sub Squares
Fridge: Store leftover Italian Sub Squares in an airtight container for up to 3 days to maintain freshness and flavor.
Freezer: Wrap individual squares in plastic wrap and place them in a freezer-safe bag for up to 2 months. Thaw in the fridge before reheating.
Reheating: To regain that flaky texture, reheat in the oven at 350 °F (175 °C) for about 10-15 minutes until warm and crisp.
Room Temperature: If serving fresh, keep them at room temperature for no more than 2 hours to ensure food safety.
Italian Sub Squares Recipe FAQs
How do I select the right ingredients for my Italian Sub Squares?
Absolutely! For the best flavor, choose fresh ingredients. Look for crescent roll dough that feels soft and pillowy, while the deli meats should be freshly sliced for optimal taste. When selecting your cheeses, make sure they are full-flavored; avoid any that appear dried out or too crumbly.
How should I store leftover Italian Sub Squares, and how long do they last?
To keep your Italian Sub Squares fresh, store them in an airtight container in the refrigerator for up to 3 days. This helps maintain their delicious flavor and texture. If they start to dry out, you can reheat them lightly, adding a sprinkle of water to keep them moist.
Can I freeze Italian Sub Squares, and how do I do it?
Very much! To freeze, wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 3 months. When you re ready to enjoy them again, simply thaw overnight in the fridge. To reheat, bake in a preheated oven at 350 °F (175 °C) for about 10-15 minutes for that crispy and flaky texture.
What if my Italian Sub Squares turn out soggy?
If you find your squares are soggy, it may be due to excess moisture from filling ingredients like giardiniera or muffuletta. To avoid this, ensure these components are well-drained and patted dry before layering them. Additionally, allowing the squares to cool completely before cutting can help retain structure.
Are there any dietary considerations to keep in mind while making Italian Sub Squares?
Yes, indeed! If you re preparing this dish for someone with dietary restrictions, there are plenty of substitutes to make it accessible. Use gluten-free crescent roll dough for those with gluten sensitivities. For a dairy-free option, try plant-based cheeses, and incorporating roasted vegetables in place of meats is a wonderful way to cater to vegans or vegetarians.
Can I use different fillings in my Italian Sub Squares?
Absolutely! The beauty of Italian Sub Squares lies in their versatility. You can mix and match fillings, using any combination of deli meats, cheeses, and even veggies. Experimenting with different sauces or condiments will also enhance the flavor profile, making them uniquely yours!
