Step 2: Equipment Needed

To prepare Italian Sub Squares, make sure you have the following:

• 9×13 Baking Dish: Ensures even baking and a perfect shape.
• Mixing Bowl: For preparing the pesto-egg wash mixture.
• Pastry Brush: Helps evenly distribute the egg wash or pesto topping.
• Knife or Pizza Cutter: For slicing into squares after baking.
• Non-Stick Foil or Cooking Spray: Prevents sticking and helps with an even bake.

Step 3: Preparing the Layers

1. Preheat oven to 350°F. Spray a 9×13 baking dish with cooking spray.
2. Unroll one sheet of crescent roll dough and press it into the bottom of the baking dish, ensuring it reaches about 1 inch up the sides.
3. Layer half of the cheese on the bottom.
4. Add the meats in the following order: pepperoni, ham, then salami.
5. Top with red bell peppers and pepperoncini slices.
6. Add the remaining provolone cheese on top.
7. Unroll the second crescent roll sheet and place it over the filling, pressing the edges together to seal.

Step 4: Baking Instructions

1. Whisk together the egg, pesto, and Parmesan cheese in a small bowl.
2. Brush the mixture over the top of the dough using a pastry brush.
3. Cover with non-stick foil and bake for 30 minutes.
4. Remove foil and continue baking for another 15-20 minutes, until the top is golden brown.
5. Let cool for 10 minutes before slicing into squares.

Tips for Making the Best Italian Sub Squares

• Use high-quality deli meats for the best flavor.
• Drain excess moisture from roasted peppers and pepperoncini to prevent sogginess.
• Ensure even layering so every bite has the perfect balance of ingredients.
• Press the dough edges tightly to prevent cheese leakage.
• Let the squares cool before slicing for cleaner cuts.
• For extra crispiness, brush olive oil on the top layer before baking.

Common Mistakes to Avoid When Preparing Italian Sub Squares

• Skipping the egg wash or pesto topping: This helps achieve a golden, flavorful crust.
• Not sealing the dough edges properly: This prevents cheese from leaking out during baking.
• Overloading with ingredients: Too much filling can cause the dough to bake unevenly.
• Not preheating the oven: Ensures even cooking and a crispy crust.
• Cutting too soon after baking: Letting the squares rest prevents them from falling apart.
