Vegetarian Antipasto Sliders Recipe: 12 Crowd-Pleasing Bites
These crowd-pleasing vegetarian antipasto sliders feature roasted veggies, provolone, and a tangy spread in mini slider buns for an easy, flavorful bite.
These Vegetarian Antipasto Sliders capture the vibrant flavors of an Italian antipasto platter in a convenient, handheld form. Layers of roasted eggplant, zucchini, and bell peppers are topped with provolone cheese and a zesty cream cheese spread, all nestled in soft slider buns. They’re perfect for game day gatherings, cocktail parties, or casual weeknight meals, offering a meat-free option that’s both satisfying and impressive.
Antipasto, meaning “before the meal” in Italian, traditionally features cured meats, cheeses, and marinated vegetables. This vegetarian twist swaps in hearty roasted veggies for a lighter yet flavorful profile. Each slider delivers smoky, charred vegetables balanced by creamy cheese elements, making them irresistible even to carnivores. Best of all, they come together in about 40 minutes with minimal hands-on time, thanks to simple roasting and assembly.

Ingredients
This recipe yields 12 sliders. Ingredients are straightforward pantry staples with fresh produce for maximum flavor.
For the Roasted Vegetables:
- 1 medium eggplant (about 1 lb), sliced into ¼-inch thick rounds
- 1 medium zucchini (about 8 oz), sliced into ¼-inch thick rounds
- 1 red bell pepper, seeded and cut into ½-inch strips
- 1 yellow bell pepper, seeded and cut into ½-inch strips
- 2 tablespoons olive oil
- 1 teaspoon dried Italian seasoning
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
For the Herbed Cream Cheese Spread:
- 8 oz cream cheese, softened
- ¼ cup chopped fresh basil
- 2 tablespoons chopped fresh parsley
- 1 garlic clove, minced
- 1 tablespoon lemon juice
- ¼ teaspoon salt
For Assembly:
- 12 slider buns or Hawaiian rolls, split
- 12 slices provolone cheese (about 6 oz total)
- ¼ cup sliced pepperoncini peppers (optional, for heat)
- 2 tablespoons balsamic glaze (optional, for drizzling)
Tip: Use reduced-fat cream cheese or dairy-free alternatives for a lighter version. Gluten-free slider buns work seamlessly.
Directions
- Preheat Oven: Position racks in upper and lower thirds of oven; preheat to 425°F. Line two large rimmed baking sheets with parchment paper.
- Prepare Vegetables: In a large bowl, toss eggplant, zucchini, and bell peppers with oil, Italian seasoning, salt, and black pepper until evenly coated. Divide between prepared baking sheets in a single layer.
- Roast: Bake until vegetables are tender and lightly charred, 20-25 minutes, rotating sheets and stirring veggies halfway through for even cooking.
- Make Spread: Meanwhile, in a medium bowl, combine cream cheese, basil, parsley, garlic, lemon juice, and salt. Beat with an electric mixer on medium speed until smooth and fluffy, about 1 minute. Cover and refrigerate until ready to use.
- Toast Buns: Place bun bottoms and tops, cut-sides up, on a third baking sheet. Bake on upper oven rack until lightly toasted, 3-4 minutes.
- Assemble Sliders: Spread about 1 tablespoon herbed cream cheese on each bun bottom. Layer with 1 slice provolone, roasted veggies (2-3 pieces per slider), and a few pepperoncini slices if desired. Cap with bun tops. Drizzle with balsamic glaze if using.
- Serve: Arrange on a platter and serve immediately. For best texture, enjoy within 30 minutes of assembly.
