Hot Italian Sub Sliders

These Hot Italian Sub Sliders transform classic Italian subs into an irresistible baked treat perfect for feeding a crowd. The combination of savory deli meats and melty cheese nestled in soft Hawaiian rolls creates an appetizer that disappears in minutes at any gathering.

I first made these for a last-minute Super Bowl party when I needed something impressive without spending hours in the kitchen. The tray was empty before halftime even started and I've been making them for every gathering since.

Ingredients

• Hawaiian rolls: Soft sweet base that caramelizes beautifully when baked
• Mayonnaise: Creates a creamy base that prevents the bread from getting soggy
• Italian dressing: Adds classic Italian flavor throughout each bite
• Salami: Adds rich savory flavor; choose high quality for best results
• Pepperoni: Provides a subtle spicy kick; look for pepperoni that has visible specks of spices
• Ham: Balances the spicier meats with its mild flavor; select thinly sliced for best layering
• Provolone cheese: Melts perfectly with a slight tanginess; choose aged for more flavor
• Roasted red peppers: Sweet smoky flavor that brightens each bite; pat them completely dry before adding
• Banana peppers: Tangy vinegar notes that cut through the richness; drain well before using
• Italian seasoning: Ties all flavors together with classic herbs
• Butter: Creates a golden crispy top that seals in all the flavors
• Garlic powder: Infuses the butter topping with aromatic flavor
• Parmesan cheese: Adds nutty salty finish to the tops of the sliders

Step-by-Step Instructions

Preheat Oven:

Begin by heating your oven to 350°F and lightly greasing a 9×13 baking dish. This temperature is ideal for melting cheese while gradually crisping the rolls without burning them.

Prepare Rolls:

Keep the Hawaiian rolls connected and slice them horizontally as one unit. This technique makes assembly infinitely easier and ensures the sliders stay together when serving.

Create Flavor Base:

Mix mayonnaise and Italian dressing until completely combined. This spread is crucial as it creates a moisture barrier that prevents the bread from becoming soggy while adding tanginess to complement the rich meats.

Layer Strategically:

Start with salami on the bottom as it creates a solid base. Follow with pepperoni, ham, provolone, then the peppers. This specific order ensures optimal melting and flavor distribution throughout each bite. Make sure every inch is covered with each ingredient for consistent flavor.

Prepare Butter Topping:

Whisk melted butter with garlic powder, Italian seasoning, and Parmesan until fully incorporated. This mixture not only adds incredible flavor but also creates that irresistible golden top that makes these sliders Instagram worthy.

Two-Stage Baking:

Cover tightly with foil for the first 10 minutes to trap steam and help the cheese melt evenly. Removing the foil for the final 5-7 minutes allows the tops to become beautifully golden and slightly crisp, creating textural contrast.

Pin it

The Italian dressing is my secret ingredient here. While many recipes call for mayonnaise alone, I discovered that mixing it with Italian dressing adds an incredible depth of flavor that reminds me of the authentic Italian subs my grandmother would make for Sunday family gatherings. The tangy herbal notes make all the difference.

Make-Ahead Instructions

These sliders are perfect for preparing in advance, which makes them ideal for entertaining. Assemble the entire recipe up to the baking step, cover tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to serve, remove from the refrigerator while the oven preheats, add the butter topping just before baking, and add an extra 3-5 minutes to the covered baking time since they'll be starting cold.

Ingredient Substitutions

Hawaiian rolls can be a game changer for these sliders, but if unavailable, regular slider buns work well; just brush them with a bit of honey butter before assembly to mimic the sweetness. For a healthier option, try whole wheat slider buns. The deli meats can be customized based on preference: salami can be swapped for soppressata; ham for mortadella; or vegetarians can use grilled vegetables and extra cheese. For those avoiding dairy, try dairy-free mayonnaise and vegan cheese alternatives.

Serving Suggestions

These hot Italian sub sliders make an excellent centerpiece for any casual gathering. For game day, pair them with cold beverages and crunchy sides like kettle chips or a simple green salad with Italian vinaigrette to balance the richness. For a more substantial meal, serve alongside a cup of tomato soup or minestrone. Cut sliders into individual portions before serving and arrange on a platter surrounded by extra banana peppers, pickles, and small bowls of warmed marinara sauce for dipping.
