How to Make It (Step-by-Step)
Prep time: 15 minutes | Bake time: 25–30 minutes | Total time: 45 minutes | Yield: 12 Squares
Step 1: Prep and Preheat
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with non-stick cooking spray so the bottom crust doesn’t stick.
Step 2: The Bottom Crust
Unroll the first can of crescent rolls. Press the dough flat into the bottom of your greased baking dish, making sure to pinch and seal the perforated seams together. Press the dough slightly up the sides of the dish to form a crust edge.
Step 3: The First Meat Layer
Layer half of your sliced turkey ham, half of the beef salami, and half of the provolone cheese evenly directly on top of the bottom crescent dough.
Step 4: The Zesty Middle
Evenly spread the pepperoni slices, the drained banana pepper rings, and the sliced roasted red peppers over the layers of meat and cheese. Sprinkle the tablespoon of Italian seasoning evenly over the peppers.
Step 5: The Final Meat Layer
Layer the remaining turkey ham, beef salami, and provolone cheese right on top of the pepper mix, sealing all those delicious flavors into the center.
Step 6: The Top Crust
Unroll the second can of crescent rolls and carefully lay it over the top of the final cheese layer. Press the edges of the top dough into the edges of the bottom dough to seal the sandwich closed, and pinch any perforated seams together.
Step 7: The Golden Finish
Use a pastry brush to lightly brush the entire top layer of crescent dough with the ¼ cup of olive oil. Sprinkle the grated Parmesan cheese evenly over the oiled dough.
Step 8: Bake and Rest
Bake in the preheated oven for 25 to 30 minutes, or until the crust is a deep golden brown and the cheese is bubbly.
💡 Crucial Step: Let the dish cool and rest for at least 10 to 15 minutes before cutting! If you cut it piping hot, the melted cheese will slide right out of the squares.
💡 Expert Tips for Success
- Pinch the Seams: Take the extra 30 seconds to really pinch the perforated triangles of the crescent dough together. If you leave gaps, the melting cheese will bubble up and spill out over the top crust!
- Dry Your Ingredients: Moisture is the enemy of crescent dough. Pat your deli meats and your drained peppers completely dry with paper towels before layering them in the dish.
- The Foil Hack: If you notice your top crust is getting perfectly golden brown but the center needs a few more minutes to bake, loosely tent a piece of aluminum foil over the pan for the last 5 to 10 minutes of baking.
Variations and Substitutions
- The Cheese Swap: If you want a slightly sharper flavor, swap the provolone out for slices of sharp white cheddar, or use a blend of mozzarella and provolone for maximum melt!
- The Spicy Kick: If your family loves heat, swap the mild banana peppers for hot pickled jalapeños, and use a spicy beef salami in the layers.
- The Veggie Sub: You can easily make this a vegetarian delight by skipping the deli meats and layering grilled zucchini, eggplant, extra roasted peppers, spinach, and a thick layer of provolone and mozzarella!
Serving Suggestions
- The Classic Sub Experience: Serve these warm squares with a side of freshly shredded iceberg lettuce and thinly sliced tomatoes tossed in a little olive oil and red wine vinegar so guests can top their own pieces!
- The Soup & Sandwich Combo: Pair these hearty squares with a warm, comforting bowl of minestrone soup or a rich tomato bisque.
- The Game Day Spread: Serve them alongside a heaping tray of antipasto loaded with olives, marinated artichokes, and crispy garlic bread.
Frequently Asked Questions (FAQs)
Can I assemble this ahead of time?
It is not recommended to assemble this too far in advance, as the wet deli meats and peppers will turn the raw crescent dough soggy before it even hits the oven. However, you can pre-slice all your meats and veggies and have them ready to layer right before baking!
How do I store and reheat leftovers?
Store any leftover squares in an airtight container in the refrigerator for up to 3 days. To keep the crust flaky, reheat them in an oven at 350°F (175°C) for about 10 minutes, or pop them in an air fryer for 3 to 4 minutes. Microwaving will make the crescent dough very soft!
