- Refrigerated crescent roll dough: This gives the squares their crisp, golden crust and a tender base that’s pure comfort food magic.
- Deli ham: Ham adds that classic savory layer, giving a mild, smoky undertone that anchors the filling.
- Genoa salami: For subtle spice and richness, you can’t beat Genoa salami—its marbled texture melts beautifully.
- Pepperoni: Pepperoni brings familiar boldness and a pop of color that makes each bite so satisfying.
- Provolone cheese: Creamy, gentle provolone melts to blanket everything in a gooey embrace.
- Mozzarella cheese: For irresistible stretchy cheese pulls, you need mozzarella—mild, melty, and kid-friendly.
- Sliced pepperoncini or banana peppers (optional): If you love a tangy, bright kick, toss in a handful for extra zing and color.
- Large eggs: Eggs bind the layers and give the filling a luxurious, custardy feel.
- Grated Parmesan cheese: Parmesan brings that nutty, salty lift that ties every flavor together.
- Italian seasoning: Classic herbs (like oregano and basil) perfume the squares with unmistakable sub shop magic.
- Garlic powder: Just a hint of garlic elevates the savory notes in the dough and filling.
- Salt and pepper: A touch of each makes every ingredient pop—don’t skip it!
How to Make Italian Sub Squares
Step 1: Prepare the Baking Dish and Dough
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so nothing sticks. Then, unroll one can of crescent dough and gently press it into the bottom, pinching the seams closed for a unified crust. This forms the flaky base that holds in all those amazing fillings.
Step 2: Build the Layered Filling
Once your dough is snuggly in place, get to layering the good stuff: start with an even spread of deli ham, followed by thin slices of Genoa salami, then pepperoni for a salty, slightly spicy boost. Add slices of provolone and mozzarella, overlapping them for ultimate cheesiness. If you like a sharp tang, sprinkle on those pepperoncini or banana peppers here. Every layer brings a bit more character to your Italian Sub Squares.
Step 3: Mix and Pour the Seasoned Egg Mixture
In a small bowl, crack both eggs and give them a good whisk. Stir in the Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper. Pour this herby, creamy mixture evenly across your layered meats and cheese. This transforms the filling into a gorgeous, slightly custardy center that’s a little bit like quiche and a lot like sub heaven.
Step 4: Seal and Top with More Dough
Take your second can of crescent dough, unroll it, and lay it over the top. Pinch any seams together and press gently on the edges so all that amazingness is tucked in. The second layer ensures your squares bake up perfectly golden with a tender, flaky bite—from top to bottom.
Step 5: Bake to Golden Perfection
Slide it into the oven and bake for 25–30 minutes. When the top is shimmering gold and the filling looks set, it’s finished. Let the pan cool for about 10 minutes—this makes slicing easier and keeps the cheese intact—then cut into generous squares and serve. Each bite is warm, melty, and satisfying, just like a deli sandwich fresh from the oven!
How to Serve Italian Sub Squares

Garnishes
For a finishing touch, sprinkle Italian Sub Squares with a little extra grated Parmesan or chopped fresh basil just before serving. A crack of black pepper or a drizzle of olive oil can be a sophisticated upgrade, adding aroma and flavor. If you like a bit more zing, serve with extra pepperoncini or even a few mild pickled veggies on the side.
Side Dishes
Pair these hearty squares with a crisp green salad tossed in Italian dressing, or maybe a simple tomato and cucumber salad for a refreshing contrast. Chips, fries, or even a bowl of minestrone soup turn Italian Sub Squares into a complete, comforting meal, whether for lunch, dinner, or a casual party spread.
Creative Ways to Present
For parties, arrange Italian Sub Squares on a big platter with colorful toothpicks—they’re irresistible finger food! You can cut them smaller for appetizers or slightly bigger for meal portions. Try serving them in parchment wrappers or individual baskets with a tiny bowl of marinara for dipping. If you want an antipasto twist, scatter a few olives or artichoke hearts around the tray for extra flair.
Make Ahead and Storage
Storing Leftovers
Leftover Italian Sub Squares keep beautifully in an airtight container in the fridge for up to three days. The flavors even deepen overnight, making next-day squares perfect for a quick snack or easy lunch. They’re just as enjoyable cold as they are reheated!
Freezing
These squares are super freezer-friendly! Let them cool completely, then wrap tightly in foil and place in a freezer bag. They’ll hold up well for up to two months, so you can always have a batch of Italian Sub Squares ready for unexpected company or future cravings.
Reheating
To bring back that just-baked magic, reheat Italian Sub Squares in a 350°F oven, covered loosely with foil, for about 10 minutes. The crust crisps up and the cheese gets melty again. In a pinch, a microwave works too—cover and heat on medium until warmed through—but the oven really shines for texture!
FAQs
Can I add extra veggies to my Italian Sub Squares?
Absolutely! Sliced black olives, roasted red peppers, or even baby spinach can be tucked between those layers of meat and cheese for a boost of color and flavor. Add them before pouring on the egg mixture so everything bakes together perfectly.
Are Italian Sub Squares good served cold?
Yes—these are just as tasty at room temperature or cold as they are warm, making them a great make-ahead option for picnics, work lunches, or easy snacking straight from the fridge.
What’s the best way to prevent the crescent dough from getting soggy?
Make sure to let the finished squares cool for about 10 minutes before slicing, giving the filling a chance to set and keeping the crust from getting too moist. Don’t overload with too many juicy vegetables, and always use well-drained deli meats and peppers.
Can I make this recipe vegetarian?
You sure can! Swap the meats for grilled or roasted vegetables like zucchini, eggplant, or bell peppers. Be sure to season them well and pat dry so the crust stays flaky.
How do I get perfectly clean slices when serving?
Let your Italian Sub Squares cool slightly, then use a sharp, serrated knife to cut through the crust and filling. Wipe the blade between cuts for neat, bakery-style squares every time.
