Why I love this pizza sliders recipe

This pizza sliders recipe is a great option when you want an appetizer that you know people will actually eat.

You get all the cheesy, saucy goodness of pizza in a small, easy-to-grab sandwich, making them especially good for game day, parties and other casual get-togethers.

And unlike some party appetizers that disappear in a bite or two, these are substantial enough to be satisfying.

You can also easily change the toppings to suit your crowd, whether you stick with pepperoni and vegetables or swap in your own favorite pizza combination.

pizza sliders ingredients

Here is your shopping list (for 12 sliders):

  • Bread – 1 12-count package sweet Hawaiian rolls
  • Fresh produce – 4 medium mushrooms, 1 medium yellow pepper, 1 small red onion.
  • Jarred goods – 1 cup pizza sauce
  • Refrigerated Meats – ½ cup pepperoni slices
  • Dairy – 1 ½ cups shredded mozzarella cheese

Substitutions & Additions

  • Use another color of bell pepper in place of the yellow pepper if desired.
  • You can also swap the pizza toppings for other finely chopped pizza toppings that will cook through during the short baking time.

How to make pizza sliders

  • 1 | Prep work

    Preheat the oven to 375°F so it is fully heated before the assembled sliders go in.

    Line a baking sheet with parchment paper.

    Chop the mushrooms, yellow pepper and red onion.

    Pro tip:

    All of the produce should be chopped into fairly small pieces so that it can be more evenly distributed over all of the sliders.
  • 2 | Cook the onions and peppers

    Peppers and onions in a saute pan.

    Add the olive oil to a small saucepan and heat it over medium heat.

    Give the oil a minute or two to warm up before adding the vegetables so they begin cooking right away.

    Add the diced yellow pepper and red onion to the warm oil.

    Cook for 3 to 5 minutes, stirring occasionally, until the vegetables have softened.

    Remove the pan from the heat and set the mixture aside.

  • 3 | Cut the rolls

    Hawaiian rolls cut in half on a parchment-covered baking sheet

    Keep the rolls connected in one block and use a serrated knife to slice horizontally through the middle.

    Saw gently rather than pressing down so the soft rolls do not get crushed.

    Lift off the top half and set it aside.

    Transfer the connected bottom half of the rolls to the parchment-lined baking sheet, keeping the slab intact.

    Pro tip:

    A long serrated bread knife makes it easier to cut through the entire slab of rolls at an even height.

  • 4 | Put the sliders together

    Pizza sauce and shredded mozzarella on the bottom half of the rolls.

    Spread the pizza sauce over the cut surface of the bottom half of the rolls.

    Take it close to the edges so each slider gets enough sauce.

    Sprinkle half of the shredded mozzarella evenly over the pizza sauce.

    Pepperoni layered over mozzarella and pizza sauce on the slider rolls.

    Arrange the pepperoni slices in a single layer over the mozzarella, distributing them across the entire slab so every slider is covered with it.

    Olives, mushrooms, yellow pepper and red onion layered over the pepperoni.

    Scatter the sliced olives, diced mushrooms and cooked pepper-and-onion mixture evenly over the pepperoni.

    Shredded mozzarella covering the pizza slider toppings before the top rolls are added.

    Cover the toppings with the remaining mozzarella cheese, distributing it evenly across the sliders.

    This top layer will melt around the vegetables and pepperoni and help hold the filling together.

    Assembled pizza sliders brushed with Italian dressing before baking.

    Set the connected top half of the rolls back over the filling.

    Line it up with the bottom slab so the individual rolls match up and the filling stays enclosed.

    Use a pastry brush to coat the tops of the rolls with the Italian dressing.

    Brush it across the whole surface, including the edges, so the rolls brown and pick up the dressing’s seasoning as they bake.

  • 5 | Bake

    Baked pizza sliders with browned tops and melted cheese filling.

    Bake the sliders at 375°F for 12 to 15 minutes.

    They are ready when the cheese is melted and the tops of the rolls are browned and slightly crisp.

    Watch them near the end of the baking time because the sweet rolls can brown quickly.

  • 6 | Serve

    Serve the pizza sliders while they are hot.

    For easier serving, separate the individual sliders along the natural seams of the rolls before taking them out.

How to make ahead

You can assemble the sliders through adding the top half of the rolls a few hours ahead.

Cover and refrigerate, then brush with Italian dressing just before baking.

Add a few extra minutes to the baking time if they are going into the oven cold.

Storage

Pizza sliders are best served fresh.

But if you do have leftovers, you can store them in an airtight container in the refrigerator for up to 2 days.

Then reheat in the oven at 350°F for a few minutes before serving.

You can also use the microwave, but the rolls won’t maintain their texture as well.
