Ingredients in Italian Sliders
For exact measurements, see the recipe card below.
- Olive Oil – Use light-tasting olive oil or extra virgin. I wouldn’t use other oils here; the olive oil adds to the distinct taste of this dressing.
- Red Wine Vinegar – Use white wine vinegar or apple cider vinegar in a pinch.
- Italian Seasoning – Or make your own Italian seasoning using a mix of dried oregano, basil, thyme, and rosemary.
- Dijon Mustard – Yellow mustard will work too.
- Salted Butter – Unsalted butter works great too.
- Chopped Parsley – Optional, it adds a nice freshness.
- Garlic Powder – You could also use minced fresh or jarred garlic.
- Onion Powder
- Salt – Optional as the meats are salty, but I enjoy a bit extra.
- Grated Parmesan Cheese – Shredded Parmesan would also work.
- Hawaiian Slider Rolls – Individual slider buns or sweet rolls will also work for this recipe.
- Deli Ham – I like getting the meat from the deli, but you can use prepackaged meats and cheeses.
- Salami – Prosciutto works great too.
- Pepperoni – Use leftover pepperoni for pizza later in the week.
- Provolone – Cheese Swiss or mozzarella cheese are great replacements.
- Red Onion – Or a white, yellow, or sweet onion. The red onion has a great bite to it.
- Cherry Tomatoes – Or slice up a regular-sized tomato.
- Sliced Pepperoncini – Banana peppers or chopped green chilies are great replacements.
- Shredded Iceberg Lettuce – Iceberg is traditional and cost effective, but use any type of lettuce that you like here.

2. Mix the dressing and the butter topping.
• In a small bowl, whisk together the olive oil, red wine vinegar, Italian seasoning, and Dijon mustard. Refrigerate to let the flavors blend while you prepare the sliders.

FAQ About Hawaiian Roll Sliders
Here's what people are asking about Sliders:
- What kind of bread should I use?
Hawaiian rolls are the preferred choice as they are soft and slightly sweet, which balances the savory meats and tangy dressing. However, any slider buns will work. - Can I serve these cold instead of hot?
Yes! They’re delicious warm & melty, these sliders are also great served cold, like a traditional sub. Either skip the baking step and brush the butter mixture on the top rolls as-is. Or bake them and let them cool. - Can I make this vegetarian?
You can! Replace the meats with roasted red peppers, marinated artichokes, and sliced olives for a delicious vegetarian version. - Can I make this ahead of time and freeze it?
This sandwich is best enjoyed right after it is made. The vegetables in the sandwich will get soggy if they are frozen and thawed. - What’s the best way to transport these for a potluck or party?
Once baked, cover the dish with foil and transport it in an insulated carrier to keep warm, if desired. Then add the lettuce and dressing just before serving for the best texture. - Can I Make These Ahead?
You can prep these sliders a few hours in advance (up to the baking step). Cover and refrigerate, then bake just before serving. Add the lettuce and dressing after baking to keep everything fresh and crisp. Freezing is not recommended due to the fresh vegetables.
Storage Instructions for Leftover Italian Deli Sliders
Refrigerate: Store leftover Italian sub sliders in an airtight container in the refrigerator for up to 2–3 days. After a few days the veggies may start to make the bread soggy.
How to Reheat Italian Sub Sliders
You can reheat these Hawaiian Roll Italian Sliders using the oven, microwave, or air fryer:
• Oven: Preheat to 350°F. Place sliders in a baking dish, cover with foil, and bake for 8–10 minutes or until heated through. For best results, remove any lettuce before reheating and add it back afterward.
• Microwave: Place one or two sliders on a microwave-safe plate and heat for about 1 minute. The bread will be softer, but it’s quick and easy.
• Air Fryer: Preheat to 330°F. Place sliders in a single layer in the air fryer basket and heat for 3–5 minutes until warmed through.

Reheating

Oven: Place your leftovers in a 9x13-inch casserole dish and reheat your sliders at 350°F for 8-10 minutes or until warmed throughout. I like to pick the lettuce off so it doesn’t get wilted.
Microwave: Place individual servings on a microwave-safe plate and heat for 1 minute.
Air Fryer: 330°F for about 3-5 minutes. Check and add more time if needed.
