How to Make Italian Sub Squares
Preheat your oven to 375 °F (190 °C) and grease a 9 13-inch baking dish to ensure easy removal once baked. The warm oven is key to achieving that golden, flaky crust!
Prepare the Dough: Unroll one can of crescent roll dough and press it into the bottom of the greased dish, making sure to seal any seams. This will create a solid, enjoyable base for your delicious filling.
Layer Fillings: Begin layering with provolone cheese, followed by the sliced deli meats (ham, salami, pepperoni). Add mozzarella, roasted red peppers, and banana peppers if you re using them. Each layer brings a unique flavor burst!
Top with Dough: Unroll the second can of dough on top of your layered fillings, carefully sealing the edges. This will encase all that tasty goodness, ensuring every square is filled with flavor.
Season & Bake: Brush the top with melted butter and sprinkle with dried Italian seasoning. Bake for 25-30 minutes until the top is golden brown and the kitchen is filled with a mouthwatering aroma.
Cool & Slice: Allow the dish to cool for a few minutes before slicing into squares. This helps preserve their shape and makes serving a breeze!
