These Italian sub sliders are the perfect handheld party sandwich. Salty deli meats and Provolone cheese are layered with fresh, savory veggies and dressed with a simple, yet flavorful vinaigrette.
Servings: 12
Equipment
- 9x13-inch Baking Dish
- 2 Small Bowls
Ingredients
For the Dressing
- ¼ cup Olive Oil
- 3 Tablespoons Red Wine Vinegar
- 1 teaspoon Italian Seasoning
- ¼ teaspoon Dijon Mustard
For the Topping
- ½ cup Salted Butter, softened
- 2 teaspoons Chopped Parsley (plus more for garnish)
- 1 teaspoon Italian Seasoning
- 1 teaspoon Garlic Powder
- 1 teaspoon Onion Powder
- ½ teaspoon Salt
- ½ cup Grated Parmesan Cheese
For the Sandwiches
- 12 Hawaiian Slider Rolls (undivided but sliced horizontally)
- 12 slices Deli Ham
- 12 slices Salami
- 12 slices Pepperoni
- 8 slices Provolone Cheese
- ¼ of a Red Onion, thinly sliced
- ¼ cup Cherry Tomatoes, thinly sliced
- ¼ cup Sliced Pepperoncini
- 1 ½ cups Shredded Iceberg Lettuce
Instructions
Preheat and Prep Dish
- Preheat your oven to 350°F and spray a 9x13-inch casserole dish with non-stick spray and set aside.
Make the Dressing
- In a small bowl, make the dressing by combining the olive oil, red wine vinegar, Italian seasoning, and Dijon mustard. Place it in the refrigerator for the flavors to meld while you build your sandwiches.
Make the Topping
- In a second small bowl, make the topping by stirring together the softened butter, parsley, Italian seasoning, garlic powder, onion powder, and salt until smooth. Set aside.
Assemble
- Assemble the sandwiches by placing the bottom of the sliders into your prepared 9x13-inch casserole dish. Layer the ham, salami, and pepperoni, followed by the cheese, onion, tomatoes, and pepperoncini. Place the top over the sliders.
Brush with the Topping
- Brush the tops of the buns with the topping mixture, making sure to cover the tops of each slider.
Bake
- Bake uncovered for 20 minutes or until the sliders are heated throughout and the tops are a light golden brown.
- Remove from the oven and sprinkle the tops with Parmesan cheese. Make sure to do this straight out of the oven so the cheese melts a bit.
Add the Lettuce and Dressing
- Remove the tops of the sliders and add the shredded lettuce. Give the dressing a good stir and drizzle it over the lettuce before replacing the top of the sliders.
Slice and Serve
- Slice and serve warm or at room temperature
Notes
Storage Instructions
Leftover sliders will keep in the refrigerator for 2-3 days. They get even better as they sit, but after 2-3 days, the vegetables start to make the sandwich soggy.
Reheating
You can reheat larger portions of the sliders in the oven or individual portions in the microwave or air fryer.
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.
