Baked Italian Sub Sandwiches

by Sophia

There’s something undeniably comforting about a hearty sandwich, especially when it’s packed with savory meats, melted cheese, and wrapped in a golden, buttery crust. These Baked Italian Sub Sandwiches are my go-to when I want something easy, satisfying, and guaranteed to please a hungry crowd. Whether it’s game day, a weekend family dinner, or even just a busy weeknight when you need something quick but delicious, these sandwiches check every box.

I first made these on a whim one Sunday afternoon when we were having a few friends over for the game. I had some deli meats that needed using, and let’s be honest—who doesn’t love a melty sandwich with layers of meat and cheese? I tossed everything onto hoagie rolls, baked them with a little butter and seasoning on top, and hoped for the best. The result? Not a single sandwich left by halftime.

This is one of those recipes that feels like more than the sum of its parts. Each bite is loaded with bold flavor, from the salty meats and melty cheese to the tangy banana peppers and that perfectly crisped roll on top. And did I mention how easy they are to make? Seriously, you’ll be in and out of the kitchen in no time.

Let’s dive into the first steps of building these amazing sandwiches.

Ingredients You’ll Need

4 hoagie rolls, hinged (not sliced all the way through)

½ lb deli chicken ham
½ lb salami
½ lb roast beef or cooked ground beef

¼ lb sliced pepperoni (optional but delicious)
8 slices provolone or mozzarella cheese
½ cup pickled banana peppers or pepperoncini

½ cup sautéed onions (optional, but adds great flavor)
1 tablespoon Italian seasoning
2 tablespoons melted butter

STEP 1: Preheat and Prep Your Oven

Set your oven to 375°F (190°C). You’ll want it hot and ready because these sandwiches only need a short time to bake. Line a baking sheet with parchment paper or foil for easier cleanup later.

STEP 2: Slice the Rolls

Take each hoagie roll and slice it lengthwise, but don’t go all the way through. Think of it like opening a book. This helps keep all those yummy fillings tucked inside while they bake and makes serving them a breeze.

STEP 3: Layer the Meats

Now comes the fun part—stacking all that flavor. Start with a layer of chicken ham, followed by salami, and then either roast beef or cooked ground beef. If you’re adding pepperoni, this is where it goes in. Don’t be shy with the layers—this is a sandwich that’s meant to be indulgent.

STEP 4: Add the Cheese

Top the meats with two slices of provolone or mozzarella cheese per sandwich. The cheese melts down into the layers and helps hold everything together. Plus, who doesn’t love that gooey cheese pull when you bite into a hot sub?

STEP 5: Add the Extras

If you’re using banana peppers or sautéed onions, now’s the time to add them. The peppers add a tangy kick that balances the richness of the meats, and the onions bring a touch of sweetness. I usually go with both, but feel free to tailor it to your taste.

STEP 6: Arrange on the Baking Sheet

Carefully transfer your assembled sandwiches onto a parchment-lined baking sheet. If your rolls are stuffed full (which they should be), you might need to use two sheets or space them out a bit so they bake evenly. You want the heat to get around each one for that toasty outer crust.

STEP 7: Brush with Butter and Seasoning

In a small bowl, mix 2 tablespoons of melted butter with 1 tablespoon of Italian seasoning. Using a pastry brush (or even the back of a spoon if that’s what you’ve got), generously brush the tops of each sandwich with this buttery blend.

This step is key to getting that flavorful, golden crust. The butter soaks into the top of the hoagie rolls while the Italian herbs add a beautiful savory aroma that will fill your kitchen.

STEP 8: Bake Covered

Cover the sandwiches loosely with foil—you don’t want it pressed down on the tops, just lightly tented to help them heat through without drying out. Place the baking sheet in your preheated oven and bake for 10 to 15 minutes, or until the cheese is melted and the fillings are nice and hot.

If your sandwiches are particularly packed, go closer to the 15-minute mark to make sure everything inside is heated through.

STEP 9: Uncover and Toast the Tops

Once the fillings are heated and the cheese is melted, go ahead and remove the foil. Bake for an additional 2 to 3 minutes, uncovered, just until the tops of the rolls get slightly crisp and golden brown.

This last step makes a big difference in texture—it adds that subtle crunch that makes each bite feel like a treat. Keep a close eye on them during this part so they don’t overbrown.

STEP 10: Serve Hot and Enjoy

Remove from the oven and let the sandwiches sit for just a minute or two before serving. You can slice them in half for easier handling, or leave them whole for a seriously satisfying bite.

Pair these with a side of kettle chips, olives, or even a crisp green salad if you’re trying to balance out all that indulgence (no judgment here). They’re also great with a side of marinara or ranch if you like a little dipping action.

Tips and Easy Variations

Swap the meats: Turkey, pastrami, or even leftover grilled chicken work beautifully in this recipe. Just be sure they’re thinly sliced so everything melts and heats evenly.
Add a spread: A swipe of mayonnaise, mustard, or even garlic aioli inside the roll before baking adds extra flavor and moisture.

Make it spicy: Toss in a few slices of jalapeños or add crushed red pepper flakes to your butter mix for a spicier kick.
Go veggie: Skip the meat and go all in with roasted red peppers, spinach, sautéed mushrooms, and extra cheese for a hearty vegetarian version.
Prep ahead: You can assemble the sandwiches a few hours in advance, refrigerate them, and then pop them in the oven just before serving. Just add a couple of extra minutes to the covered baking time.

Everything you need to know to make these subs a smashing success.

You’ve layered, baked, and toasted your way to one seriously delicious meal. Whether you’re making these Baked Italian Sub Sandwiches for a hungry family dinner or serving them up during the big game, they’re guaranteed to disappear fast.

Before we wrap up, I wanted to answer a few of the most common questions that come up when making this recipe. These tips should help you feel totally confident about customizing, storing, and serving your subs like a pro.

Frequently Asked Questions

1. Can I make these Italian subs ahead of time?
Absolutely. You can assemble the sandwiches, wrap them in foil, and refrigerate them for up to 4–6 hours before baking. When you’re ready, just pop them in the oven and bake as instructed, adding a couple of extra minutes if they’re cold from the fridge.

2. What’s the best bread to use for these sandwiches?
Look for hoagie rolls or sub rolls that are sturdy but still soft enough to bite into. Rolls labeled “Italian” or “submarine” often work well. Avoid overly crusty bread like baguettes—they don’t bake up as nicely with the fillings.

3. Can I freeze these sandwiches?
Yes, you can freeze the assembled (but unbaked) sandwiches. Wrap each one tightly in foil, then place them in a freezer-safe bag. To bake from frozen, let them thaw in the fridge overnight and then bake as usual.

4. What’s a good cheese alternative if I don’t have provolone?
Mozzarella is a perfect substitute—it melts beautifully and has that classic Italian flavor. You could also use a mild cheddar or Monterey Jack for a different twist.

5. Do I have to use all three meats?
Not at all! You can mix and match with whatever deli meats you have on hand. Even just chicken ham and cheese with some peppers and onions will still taste amazing.

6. How can I make these sandwiches spicy?

For some heat, try adding sliced jalapeños, spicy banana peppers, or crushed red pepper flakes to the inside of the sandwich. You could also use a spicy salami or pepper jack cheese.

7. What sides go well with these subs?
Chips, coleslaw, pickles, potato salad, or a fresh green salad are all great options. If you’re making these for a crowd, you can even set up a mini sandwich bar with different toppings and sauces.
