Italian Sub Squares

by

Introduction

If you love the bold, zesty flavors of a classic Italian deli sandwich but need a way to serve it to a crowd without a mountain of individual rolls, Italian Sub Squares are the ultimate solution. This dish takes all the heavy hitters—salami, pepperoni, ham, and provolone—and bakes them between two layers of buttery, flaky crescent dough. As it bakes, the meats become warm and savory, the cheese turns into a molten binder, and the dough transforms into a golden, herb-flecked crust. It’s essentially a “hot-pressed” sub in casserole form. Whether you’re looking for a heavy appetizer for game day or a fun, kid-friendly weeknight dinner, these squares offer a salty, satisfying bite that’s impossible to resist.

Ingredients

The Foundation

  • 2 cans (8 oz each) Refrigerated Crescent Rolls: (Or crescent dough sheets).
  • 1/4 lb Thinly Sliced Deli Ham
  • 1/4 lb Thinly Sliced Salami: (Genoa or Hard).
  • 1/4 lb Thinly Sliced Pepperoni
  • 1/4 lb Thinly Sliced Provolone Cheese
  • 1/4 lb Thinly Sliced Mild Swiss or Mozzarella: For extra meltability.

The Zesty Layer

  • 1/2 cup Banana Peppers or Pepperoncini: Sliced and patted dry.
  • 1/4 cup Roasted Red Peppers: Pat dried and chopped (optional).

The Glaze

  • 2 tbsp Unsalted Butter: Melted.
  • 1/2 tsp Garlic Powder
  • 1 tsp Dried Italian Seasoning
  • 1 tbsp Grated Parmesan Cheese

Equipment Needed

  • 9×13 inch Baking Pan: Ungreased or lined with parchment.
  • Small Bowl: For the butter glaze.
  • Pastry Brush: To apply the glaze.

Preparation Time, Cooking Time, Total Time, Servings

  • Prep Time: 15 minutes
  • Cook Time: 20 to 25 minutes
  • Total Time: Approx. 40 minutes
  • Servings: 12 to 15 squares

Step-by-Step Instructions

1. Pre-Heat and Base Layer

Preheat your oven to 350°F (175°C). Unroll one can of crescent dough and press it into the bottom of your 9×13 pan. If using rolls, pinch the seams together to create a solid sheet.

2. The Meat and Cheese Stack

Layer your meats and cheeses in the following order:

  1. Ham: Creates a sturdy base.
  2. Provolone Cheese: Acts as the “glue.”
  3. Salami and Pepperoni: For that classic Italian spice.
  4. Peppers: Scatter the banana peppers and red peppers evenly across the meat.
  5. Swiss or Mozzarella: The final cheese layer helps seal the top crust.

3. Top the “Sub”

Unroll the second can of crescent dough and place it carefully over the top of the fillings. Stretch it to the edges and pinch the seams.

4. The Herb Glaze

In a small bowl, whisk together the melted butter, garlic powder, and Italian seasoning. Brush the mixture generously over the top crust. Sprinkle with parmesan cheese.

5. Bake to a Golden Brown

Bake for 20 to 25 minutes. The top should be a deep golden brown and the pastry should be puffed. If the top browns too quickly, cover loosely with foil for the final 5 minutes.

6. The Essential Rest

Let the pan sit for 5 to 10 minutes before slicing. This allows the cheese to firm up slightly so the layers don’t slide apart when you cut them into squares.

Tips and Tricks

  • Dry Your Toppings: Make sure to pat your peppers (banana peppers or roasted reds) with a paper towel. Excess brine can make the dough soggy.
  • Crescent Sheets: If you can find the “Crescent Dough Sheets” (without the perforations), use them! They save you the time of pinching seams.
  • Deli Style: Ask for “thinly sliced” meats at the deli counter. Shaved meat layers better and makes the squares easier to bite through.

Variations

  • Turkey Club Squares: Swap the Italian meats for turkey and bacon, and use cheddar cheese.
  • Vegetarian Italian: Replace the meat with layers of baby spinach, artichoke hearts, and sun-dried tomatoes.
  • Spicy Italian: Use “Hot” capicola or add a layer of crushed red pepper flakes to the butter glaze.

Serving Suggestions

Serve these squares with a side of warm marinara sauce for dipping or a simple Italian side salad with a red wine vinaigrette. They are also fantastic with a side of classic potato chips or pickles.

Storage Instructions

  • Refrigeration: Store in an airtight container for up to 3 days.
  • Reheating: Reheat in a 350°F oven or toaster oven for 5–8 minutes to keep the pastry crisp. Microwaving is convenient but will result in a softer, chewier crust.
