Ingredients

• 2 cans (8 oz each) refrigerated crescent roll dough
• 1/4 lb deli ham (thinly sliced)
• 1/4 lb deli salami (thinly sliced)
• 1/4 lb deli pepperoni (thinly sliced)
• 1/4 lb deli provolone cheese (sliced)
• 1/4 cup roasted red peppers (sliced, optional)
• 1/4 cup banana peppers (sliced, optional)
• 1/4 cup black olives (sliced, optional)
• 2 tablespoons olive oil
• 1 tablespoon Italian seasoning
• 1 tablespoon Dijon mustard (optional)
• 1 egg (beaten for egg wash)
• 1 tablespoon sesame seeds (optional)

Instructions

Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or line it with parchment paper.

Step 2: Prepare the Crescent Dough

1. Open one can of crescent roll dough and unroll it onto the bottom of the prepared baking dish. Press the seams together to form an even layer of dough.

Step 3: Layer the Ingredients

1. Start with the meats: Layer the ham evenly over the crescent dough, followed by the salami and pepperoni.
2. Add the cheese: Place the provolone slices evenly over the meats.
3. Add veggies (optional): If you’re using roasted red peppers, banana peppers, or olives, sprinkle them evenly over the cheese.

Step 4: Add Seasoning and Top with Crescent Dough

1. In a small bowl, mix the olive oil, Italian seasoning, and Dijon mustard (if using). Drizzle this mixture evenly over the layered meats and cheese.
2. Open the second can of crescent roll dough and unroll it over the top of the layered ingredients, pinching the seams together to create an even dough layer.

Step 5: Egg Wash and Topping

1. Brush the top layer of crescent dough with the beaten egg to help it brown and become golden in the oven.
2. Sprinkle sesame seeds over the top (if using) for extra flavor and texture.

Step 6: Bake the Sub Squares

1. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the crescent dough is fully cooked.
2. If the top begins to brown too quickly, cover it loosely with foil during the last 10 minutes of baking.

Step 7: Cool and Slice

1. Once baked, remove from the oven and let the sub squares cool for about 10 minutes to set.
2. Slice into squares and serve warm or at room temperature.

Cook Notes

• Customizable Filling: Feel free to swap out the meats and cheeses for your favorites. Prosciutto, turkey, or mozzarella work great, too!
• Add a Kick: For a spicy version, add sliced jalapeños or sprinkle red pepper flakes between the layers.
• Storage: Store leftover sub squares in an airtight container in the refrigerator for up to 3 days. Reheat them in the oven for best results.

Variations

• Vegetarian Sub Squares: Skip the meat and load the sub squares with veggies like spinach, artichokes, mushrooms, and olives for a vegetarian option.
• Gluten-Free Version: Use gluten-free crescent roll dough to make this recipe gluten-free.
• Spicy Italian Sub Squares: Add hot pepper rings, spicy capicola, and pepper jack cheese for a spicy twist.

Frequently Asked Questions (FAQs)

Can I make Italian Sub Squares ahead of time?

Yes! You can assemble the sub squares, cover them tightly with plastic wrap, and refrigerate for up to 24 hours before baking. When ready to bake, let them sit at room temperature for about 10-15 minutes while the oven preheats.

Can I freeze Italian Sub Squares?

Yes, you can freeze the baked sub squares. Once cooled, wrap them tightly in plastic wrap and aluminum foil, and freeze for up to 2 months. Thaw in the refrigerator overnight and reheat in the oven.

What can I serve with Italian Sub Squares?

These sub squares pair well with a side salad, chips, or a light soup. You can also serve them with marinara sauce or Italian dressing for dipping.

How do I keep the bottom layer of dough from getting soggy?

Be sure to drain any excess liquid from the roasted red peppers or banana peppers before adding them. You can also pre-bake the bottom layer of crescent dough for 5-7 minutes before layering the ingredients to help prevent sogginess.

Can I use puff pastry instead of crescent roll dough?

Yes, you can substitute puff pastry for a flakier, crispier crust. Roll out the puff pastry to fit your baking dish and follow the same layering instructions.
