Ingredients You’ll Need
The magic of the Baked Italian Sub Sandwiches Recipe lies in its simple yet essential ingredients. Each component adds its own unique layer of flavor, texture, or color, ensuring every bite is a delicious experience. From the crisp sub rolls to the rich cheeses and zesty seasonings, these ingredients come together beautifully.
- 4 sub rolls sliced lengthwise but not all the way through: This keeps your sandwich intact while allowing the fillings to meld and the bread to toast evenly.
- 8 slices provolone cheese: Mild and smooth, provolone creates a wonderful gooey base layer for the sandwich.
- 6 ounces sliced ham: Adds a subtle smoky sweetness that balances the stronger meats.
- 6 ounces sliced salami: Brings a punch of spicy and robust flavor.
- 6 ounces sliced pepperoni: The classic pizza favorite adds just the right amount of zestiness.
- 1 cup shredded mozzarella cheese: For that bubbly, melty top layer that makes these sandwiches irresistible.
- 1 half cup sliced banana peppers drained: Provides a tangy, slightly spicy crunch that brightens every bite.
- 1 third cup sliced black olives (optional): Adds a salty depth and richness; great if you love olives.
- 2 tablespoons olive oil: Helps the bread toast beautifully and carries the seasoning flavors.
- 1 teaspoon Italian seasoning: A fragrant mix of herbs that wraps the sandwich in classic Italian aroma.
- 1 half teaspoon garlic powder: Infuses a subtle garlic punch without overwhelming the other flavors.
- 2 tablespoons grated Parmesan cheese: Sprinkled on top for a sharp, nutty finish and extra crispness.
- Salt and black pepper to taste: Essential for rounding out all the savory notes perfectly.
How to Make Baked Italian Sub Sandwiches Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 375°F and lining a baking sheet with parchment paper to prevent sticking. Arrange your sub rolls on the sheet and open them gently, just enough to create a cradle for the fillings without splitting them apart completely.
Step 2: Layer the Cheese and Meats
Begin by layering provolone cheese on the bottom inside of each roll. This not only adds flavor but also acts as a moisture barrier to keep the bread from getting soggy. Next, pile on the ham, followed by the salami and pepperoni, building a robust, meaty foundation for the sandwich.
Step 3: Add Mozzarella and Veggies
Sprinkle shredded mozzarella evenly over the meat layers. This cheese will melt and bind everything together when baked. Then add the banana peppers and black olives if you’re using them — these bring a welcome tang and slight briny contrast that livens up the sandwich.
Step 4: Season and Oil the Rolls
In a small bowl, whisk together olive oil, Italian seasoning, garlic powder, salt, and black pepper. Brush this aromatic mixture generously onto the tops and insides of the sub rolls. This step is crucial because it seasons the bread and helps it crisp up while baking.
Step 5: Sprinkle Parmesan and Bake
Finally, sprinkle grated Parmesan cheese over the tops of the sandwiches. Place the entire tray in the preheated oven and bake for about 12 to 15 minutes. You’ll know it’s done when the cheese is melted, bubbly, and the bread is toasted to a beautiful golden brown.
How to Serve Baked Italian Sub Sandwiches Recipe

Garnishes
Once your sandwiches are out of the oven, let them cool for a few minutes to settle the hot, gooey cheese. For an added fresh crunch and color, I love topping them with shredded lettuce or thinly sliced tomatoes. It’s a refreshing contrast that balances out all the richness.
Side Dishes
These Baked Italian Sub Sandwiches Recipe pairs beautifully with simple sides like crisp dill pickles, a light pasta salad, or even some kettle-cooked chips for a satisfying crunch. If you want to keep it balanced, a fresh green salad with a tangy vinaigrette is always a winner.
Creative Ways to Present
For gatherings or family dinners, try slicing the subs into smaller, bite-sized portions for easy sharing. You can also wrap them in foil and serve as portable lunch options that maintain their warmth and deliciousness.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (which is not very common!), wrap them tightly in plastic wrap or store in an airtight container in the refrigerator. They should stay fresh for up to 3 days, retaining most of their flavor and texture.
Freezing
This recipe freezes fairly well. Wrap each assembled but unbaked sandwich tightly in plastic wrap and then in foil before freezing. When you want to enjoy them, thaw overnight in the fridge and bake as directed for best results.
Reheating
To reheat, wrap leftovers in foil and warm in a 350°F oven for about 10 to 15 minutes. This method helps melt the cheese once again and crisps up the bread without drying out the sandwich.
FAQs
Can I use different types of cheese in this recipe?
Absolutely! Feel free to swap provolone or mozzarella for your favorite Italian-style cheeses like fontina or even a sharp cheddar for a twist. Just keep the melty texture in mind.
Is there a vegetarian version of this sandwich?
Yes, you can easily make a vegetarian Baked Italian Sub Sandwiches Recipe by using grilled vegetables like zucchini, bell peppers, and mushrooms, plus extra cheeses and banana peppers for flavor.
Can I make this ahead of time and bake later?
You can assemble the sandwiches ahead of time and keep them wrapped in the fridge for a few hours before baking. Just add the Parmesan right before baking to keep it fresh and crisp.
What if I don’t have sub rolls? Can I use another bread?
Sub rolls are ideal for their size and texture, but you can use hoagie rolls, baguettes, or even thick sandwich bread slices if needed. Just adjust baking time slightly to avoid over-toasting.
How spicy are these sandwiches with banana peppers?
The banana peppers give a gentle tangy heat that adds brightness without overpowering the other flavors. If you prefer milder, you can reduce the amount or omit the peppers entirely.
