Step 1: Make the Meatballs (Skip if Using Store-Bought)

Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a large bowl, mix ground beef, breadcrumbs, Parmesan, egg, garlic, Italian seasoning, salt, and pepper until just combined.

Roll the mixture into 1-inch meatballs and place them on the prepared baking sheet.

Bake for 15-18 minutes, or until the internal temperature reaches 165°F (75°C).

Step 2: Prepare the Sauce

In a saucepan, heat olive oil over medium heat.

Add marinara sauce and red pepper flakes, stirring occasionally.

Simmer for 5 minutes, then remove from heat.

Toss the cooked meatballs in the sauce until evenly coated.

Step 3: Assemble the Sliders

Slice the Hawaiian rolls in half horizontally, keeping them connected.

Place the bottom half of the rolls in a baking dish.

Arrange the saucy meatballs evenly on top.

Sprinkle mozzarella cheese over the meatballs.

Place the top half of the rolls back on.

Step 4: Brush and Bake

In a small bowl, mix melted butter, garlic powder, and parsley.

Brush the tops of the rolls generously with the butter mixture.

Cover with foil and bake at 350°F (175°C) for 10 minutes.

Remove the foil and bake for another 2-5 minutes until golden brown.

Step 5: Serve and Enjoy!

Let the sliders cool slightly, then cut them apart.

Serve hot with extra marinara sauce for dipping. Enjoy! 😋
