Make the meatballs
- Heat the oven to 400°F and line a rimmed baking sheet with parchment paper.
- Gently mix the ground beef, breadcrumbs, egg, Parmesan, garlic, parsley, salt, and pepper in a large bowl until just combined.
- Shape the mixture into 12 meatballs and place them on the baking sheet.
- Bake for 16–20 minutes, until the centers reach 160°F.
Assemble and bake
- Reduce the oven temperature to 350°F.
- Slice the rolls horizontally as one slab, keeping the tops and bottoms connected, and place the bottom slab in a 9x13-inch baking dish.
- Arrange the meatballs on the rolls.
- Spoon 2 tablespoons marinara over each meatball.
- Sprinkle the mozzarella evenly over the meatballs.
- Replace the top slab.
- Stir the melted butter, Italian seasoning, and garlic powder together.
- Brush the butter mixture over the rolls and cover the dish with foil.
- Bake for 10 minutes.
- Uncover and bake for 5–8 minutes more, until the cheese is melted and the tops are lightly golden.
- Rest for 5 minutes before pulling apart and serving.
Notes
For evenly cooked meatballs, shape them to a similar size. Refrigerate leftovers in an airtight container for up to 3 days; freeze baked sliders for up to 2 months. For a gluten-free option, use gluten-free breadcrumbs and rolls.
