- Banana peppers: Lend a mild tangy crunch that livens the flavor profile.
- Red onion (thinly sliced): Offers a sweet sharpness and subtle crispness.

How to Make Italian Sub Squares Recipe
Step 1: Prepare your oven and bread
Start by preheating your oven to 350°F (175°C). This heat level is perfect for melting the provolone cheese and heating the sandwich through without drying it out. Then, slice the Italian bread horizontally to create two sturdy halves that will cradle all the delicious fillings.
Step 2: Build the flavor base
Spread a generous layer of mayonnaise on the bottom half of your bread. This creamy coat will prevent the bread from becoming soggy while adding richness. Next, drizzle the Italian dressing evenly over the mayo to infuse that unmistakable tang and Italian herbs into the base.
Step 3: Layer your meats and cheese
Arrange the salami, ham, and provolone cheese on top of the dressing. The combination of these three ingredients anchors the dish with savory, salty, and melty textures that are essential to an authentic Italian sub flavor experience.
Step 4: Add your veggie medley
Top the cheese with banana peppers, thin slices of red onion, roasted red peppers, black olives, and fresh basil leaves. Each vegetable brings its own character — from the crisp tang of banana peppers to the sweet smokiness of roasted red peppers and the fragrant punch of basil. This colorful assortment elevates the sandwich beyond the ordinary.
Step 5: Assemble and bake
Place the top half of the bread over the layered ingredients snugly, then wrap the whole sandwich tightly in aluminum foil. This wrapping ensures all the flavors meld together beautifully while the sandwich heats evenly. Pop it on a baking sheet and bake for 20 to 25 minutes until the cheese is perfectly melted and the bread is warm and inviting.
Step 6: Rest, slice, and serve
Once out of the oven, let the sandwich cool just enough so it’s manageable, then carefully unwrap and slice into delightful squares. These compact portions are ideal for sharing and guarantee every bite is packed with all the layers of flavor you crafted.
How to Serve Italian Sub Squares Recipe

Garnishes
A simple garnish of extra fresh basil leaves or a light sprinkle of Italian seasoning can add an extra touch of freshness and aroma that makes these squares even more irresistible. A small drizzle of balsamic glaze also offers a tangy-sweet contrast that pairs beautifully.
Side Dishes
Italian Sub Squares go wonderfully alongside light sides such as a crisp green salad with vinaigrette, a bowl of marinated olives, or even a small serving of pasta salad. These accompaniments complement the sandwich squares without overpowering their bold flavors.
Creative Ways to Present
For an eye-catching presentation, arrange the squares on a large platter with colorful layers alternated so guests can admire the vibrant peppers, onions, and basil peeking through. You can also add toothpicks for easy grabbing, making these perfect party finger foods.
Make Ahead and Storage
Storing Leftovers
If you have any Italian Sub Squares left, store them in an airtight container in the refrigerator for up to 3 days. Keeping them wrapped tightly prevents the bread from drying out and helps maintain that perfect texture.
Freezing
While freezing is an option, it’s best to freeze the assembled but unbaked sandwich wrapped in foil, then thaw and bake when ready. This way, the bread won’t become soggy and the flavors stay fresh.
Reheating
To enjoy leftovers warm, reheat the squares in a preheated oven at 350°F (175°C) for about 10-15 minutes. This brings back the melty cheese and toasty bread without sacrificing texture.
FAQs
Can I substitute the meats or cheese in the Italian Sub Squares Recipe?
Absolutely! Feel free to swap salami or ham with turkey, roast beef, or vegetarian deli slices, and replace provolone with mozzarella or cheddar, depending on your preference. Just keep in mind how the flavor profiles will blend.
Is it necessary to bake the sandwich, or can I eat it cold?
While you can enjoy an Italian sub cold, baking the squares melts the cheese and melds the flavors beautifully, offering a comforting, warm experience classic to this recipe.
What kind of Italian bread works best?
A sturdy, crusty Italian loaf with a soft interior is ideal. Avoid very crusty artisan breads that might become too hard when baked or overly soft sandwich breads that may turn soggy.
Can I prepare the sandwich ahead of time before baking?
Yes, you can assemble the sandwich, wrap it tightly in foil, and refrigerate for several hours before baking. Just be sure to bake it thoroughly before serving.
Are these Italian Sub Squares suitable for parties and gatherings?
Definitely! Their bite-sized, shareable nature makes them perfect for entertaining. They offer all the flavors of a classic sub in easy-to-handle pieces that guests love.
