Hot Italian Sub Sliders

There’s something magical about sliders—those little bites of comfort that somehow pack all the flavor of a full-sized sandwich into a couple of handheld bites. And when you take a beloved deli classic like a Hot Italian Sub and turn it into a gooey, oven-baked slider? Game over.

These Hot Italian Sub Sliders are everything you love about a classic Italian sandwich—savory deli meats, melty provolone, tangy banana peppers—layered inside buttery, soft rolls and baked to golden, cheesy perfection. They’re easy to prep, totally customizable, and perfect for everything from game day snacking to laid-back weeknight dinners.

I’ve made these sliders more times than I can count—mostly for parties, but also for those nights when the family is craving something warm, hearty, and a little indulgent. The best part? They’re ready in just about 30 minutes from start to finish. Whether you’re feeding a crowd or just want something cozy and quick, these sliders never disappoint.

Let’s jump into the recipe and get those ovens preheated!

Ingredients You’ll Need

Here’s everything you’ll need to make a batch of these crowd-pleasing sliders:

For the Sliders:

• 12 slider rolls or Hawaiian rolls

• ¼ cup mayonnaise

• ¼ cup Dijon mustard

• 6 slices Genoa salami

• 6 slices deli ham

• 6 slices pepperoni

• 6 slices provolone cheese

• ¼ cup sliced banana peppers

• ¼ cup thinly sliced red onion (optional)

For the Topping:

• ¼ cup unsalted butter, melted

• 1 teaspoon Italian seasoning

• ½ teaspoon garlic powder

• 1 tablespoon grated Parmesan cheese

STEP-BY-STEP INSTRUCTIONS

Step 1: Preheat the Oven and Prep Your Dish

Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish so your sliders don’t stick. I usually use a quick spray of non-stick cooking spray or brush a little olive oil on the bottom.

Step 2: Slice the Slider Rolls

Take your 12 slider rolls and slice them horizontally as one full piece—don’t separate them into individual rolls just yet. Think of it like slicing a loaf of bread into a top and bottom half. Place the bottom half of the rolls into your greased baking dish.

Tip: Hawaiian rolls work great for this recipe, but any soft dinner rolls will do the trick. The sweetness from the Hawaiian rolls contrasts perfectly with the savory meats and cheese.

Step 3: Spread the Sauces

Now it’s time to flavor the inside. Mix together ¼ cup mayonnaise and ¼ cup Dijon mustard in a small bowl (or just spread them individually if you like). Slather the mixture generously over the cut sides of both the top and bottom halves of the rolls. This step adds creaminess and a bit of tang that complements the meats beautifully.

Step 4: Layer on the Meats and Cheese

Let the layering begin! Start by placing:

• 6 slices Genoa salami

• 6 slices deli ham

• 6 slices pepperoni

You can slightly overlap them to make sure every bite gets a little of everything. After the meats, add:

• 6 slices provolone cheese (they’ll melt down into that ooey-gooey perfection)

• ¼ cup banana peppers

• And if you’re using them, ¼ cup thinly sliced red onion for a bit of bite.

This combo gives the sliders that bold Italian sub flavor—salty, spicy, cheesy, and just a little tangy.

Step 5: Cap It Off

Gently place the top half of the slider rolls back on top to complete your little sandwiches. Try to line them up so they bake evenly and stay together when you slice them later.

In Part 1, we layered up our rolls with all the delicious Italian sub fixings—salami, ham, pepperoni, provolone, banana peppers, and just the right touch of mustard and mayo. Now, it’s time for the finishing touches that really make these sliders shine: a buttery, herb-infused topping and a quick trip to the oven.

This part is what transforms your sliders from good to completely irresistible. That golden, garlicky crust on top adds so much flavor and texture—it’s honestly hard to stop at just one. And once you see how easy it is to put together, you’ll be adding this slider topping to all your baked sandwich recipes.

Step 6: Make the Garlic Butter Topping

In a small bowl, combine the following:

• ¼ cup melted unsalted butter

• 1 teaspoon Italian seasoning

• ½ teaspoon garlic powder

• 1 tablespoon grated Parmesan cheese

Give everything a good stir until well mixed. This simple combo smells incredible and brings so much savory flavor to the table.

If you want to take it up a notch, you could add a pinch of red pepper flakes or a little extra Parmesan on top right before baking. Totally optional—but highly recommended if you like a bit of heat or an extra cheesy finish.

Step 7: Brush It On

Using a pastry brush (or even a spoon if that’s what you’ve got handy), generously brush the butter mixture all over the tops of the rolls. Make sure to get into the edges and corners—you want every slider to soak up that garlicky, herby goodness.

This is what’s going to give your sliders that perfectly golden, slightly crisp top once baked.

Step 8: Bake to Perfection

Cover your baking dish with foil and pop it into your preheated 350°F (175°C) oven. Bake covered for 15 minutes—this helps everything get warm and melty without drying out the bread.

Then, remove the foil and bake for an additional 5 to 7 minutes, just until the tops are golden brown and the cheese is perfectly melted.

At this point, your kitchen will smell like a little Italian sandwich shop—and it’s honestly the best kind of torture while you wait.

Step 9: Let Them Rest, Then Slice

Once the sliders are out of the oven, let them rest for a few minutes in the pan. This helps everything set up a bit, so the cheese doesn’t ooze out the second you slice into them.

Then, using a sharp knife, slice the sliders along the seams into individual servings and serve them warm.

Tips & Variations

These sliders are super versatile, so don’t be afraid to make them your own! Here are a few of my favorite ways to switch things up:

• Mix Up the Meats: Try swapping in capicola, turkey, or even roast beef. You can stick to one or layer two or three together—whatever you like.

• Go Spicy: Use hot banana peppers or add a drizzle of spicy Italian dressing inside the sandwich before baking.

• Cheese Options: Mozzarella, fontina, or sharp provolone all work well. Use what you have on hand or what you love most.

• Make Ahead Friendly: These can be assembled earlier in the day, covered tightly with foil, and stored in the fridge until you’re ready to bake. Just be sure to let them sit at room temp for about 10–15 minutes before baking so they warm up a bit.

• Leftovers? No Problem: Reheat leftover sliders in the oven at 300°F for about 10 minutes or pop them in the air fryer for a few minutes to get them warm and crispy again.
