Italian Sub Squares are the kind of nostalgic, crowd-pleasing recipe that instantly brings back memories of family gatherings, casual weekends, and game-day tables covered with simple homemade food.

This dish takes everything people love about a classic Italian sub sandwich—savory deli meats, melted provolone, pepperoni, tangy peppers, herbs, and cheese—and layers it all between two sheets of buttery crescent-roll dough.

Once baked, the crust becomes golden and flaky while the filling turns warm, melty, and incredibly satisfying.

The best part is how easy these squares are to serve. Instead of making individual sandwiches, you bake everything in one pan and cut it into neat portions. That makes them perfect for parties, potlucks, family dinners, school events, tailgates, or any occasion where you need something filling that guests can simply grab and enjoy.

Italian Sub Squares

Servings: 12

Ingredients

• 2 cans refrigerated crescent rolls
• 1/2 pound sliced ham
• 1/2 pound sliced salami
• 1/2 pound sliced provolone cheese
• 1/2 cup sliced pepperoni
• 1/2 cup banana pepper rings, drained
• 1/2 cup roasted red peppers, drained and sliced
• 1 tablespoon Italian seasoning
• 1/4 cup grated Parmesan cheese
• 1/4 cup olive oil
• Optional: lettuce and tomato slices for serving

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish so the crescent crust releases easily after baking.

Step 2: Create the Bottom Crust

Unroll one can of refrigerated crescent-roll dough.

Press the dough into the bottom of the prepared baking dish, gently pressing the seams together so they are sealed.

Press the dough slightly up the sides of the dish to help contain the filling.

Step 3: Add the First Layer of Meat and Cheese

Arrange half of the sliced ham evenly over the dough.

Add half of the salami, followed by half of the provolone cheese.

Try to distribute everything evenly so each square gets a good combination of meat and cheese.

Step 4: Add the Pepperoni and Peppers

Spread the sliced pepperoni evenly across the meat and cheese layer.

Add the drained banana pepper rings and sliced roasted red peppers.

Draining the peppers well is important because too much liquid can make the bottom crust soggy.

Step 5: Add the Italian Seasoning

Sprinkle the Italian seasoning evenly across the filling.

This adds the familiar blend of oregano, basil, and other herbs that gives Italian-style sandwiches their distinctive flavor.

Once the first layers are in place, the second layer of meats and cheese turns this simple bake into a thick, satisfying sub-style casserole.
