I used to struggle with making deli-style sandwiches at home that didn’t fall flat. Cold cuts on basic bread with sad slices of cheese? Not anymore. These baked Italian sub sandwiches solve all that.

Even my skeptical grandmother—who usually turns her nose up at anything not made from scratch—took one bite and said, “Now that’s a sandwich.”
You’ll love how customizable they are—swap meats, add veggies, choose your heat level. Whether you want a classic combo or a veggie-loaded version, this recipe molds to your cravings. Now let’s get to the good stuff!

Brings spice and that signature Italian kick.
Substitute: Prosciutto or spicy soppressata. - Pepperoni (6 slices per sandwich)
Melts beautifully, adds smokiness.
Substitute: Turkey pepperoni or omit for milder flavor.
Cheeses
- Provolone cheese (2 slices per sandwich)

Substitute: Mozzarella for extra gooeyness or sharp cheddar for a twist.

How to Make Baked Italian Sub Sandwiches
1. Prep Your Station
Preheat your oven to 375°F (190°C). Line a baking sheet with foil or parchment for easy cleanup. Slice your hoagie rolls lengthwise, leaving a hinge so they don’t fall apart.
2. Build the Layers
Drizzle the inside of each roll with Italian dressing. Add the provolone first—it melts into the bread. Next, layer your meats: salami, then capicola, then pepperoni. Top with banana peppers, onions, and a sprinkle of oregano and red pepper flakes.
Tip: Don’t overstuff—balance is key to that perfect bite.
3. Bake to Perfection
Place your subs open-faced on the baking sheet. Bake for 10–12 minutes, or until the cheese is bubbling and the bread is lightly toasted. For extra crispiness, broil the last 1–2 minutes.
Visual Cue: Edges golden, cheese fully melted.
4. Finish and Serve
Remove from the oven, let cool slightly. Add lettuce, tomato, and any cold toppings you love. Press gently to close, slice in half, and serve warm.
Pro Tip: Wrap leftovers in foil and reheat in the oven to preserve that crunchy crust.
Creative Variations to Try
1. Spicy Italian Melt
Swap provolone for pepper jack and add pickled jalapeños and hot sauce drizzle before baking.
2. Veggie Lover’s Delight
Skip the meats and add roasted zucchini, eggplant, and red peppers with mozzarella and pesto.
3. Thanksgiving Sub
Use leftover turkey, stuffing, cranberry sauce, and a layer of Swiss cheese.
4. Caprese Italian Sub
Fresh mozzarella, tomato slices, basil, balsamic glaze—bake just long enough to warm through.
5. Breakfast Italian Sub
Add scrambled eggs, crispy prosciutto, and sharp provolone. Serve with marinara dipping sauce.
6. Holiday Baked Sub
Add fig jam, brie, and prosciutto for a sweet-savory seasonal twist.
