Preheat your oven to 375°F and line a large baking sheet with parchment paper (this keeps everything golden and cleanup easy).
Unroll the crescent dough and separate it into the 8 big triangles. Grab a pizza cutter or sharp knife and slice each triangle lengthwise into two long, skinny triangles—you’ll end up with 16 pieces total. Boom—mini slider bases ready!
Cut each slice of mozzarella into 4 long strips (you’ll use one strip per bite). Lay a strip right down the center of each skinny crescent triangle.
Grab your thawed meatballs and nestle one onto the wide end of each dough strip.
Scoop a little marinara into a small bowl and brush each meatball generously so they’re glossy and saucy (this keeps everything extra juicy and flavorful). Ready for roll-up!
Starting at the wide end, gently roll the dough (with the cheese strip inside) around the saucy meatball, tucking everything in like a tiny edible burrito.
Place each little bundle seam-side down on your parchment-lined baking sheet, spacing them about 2 inches apart. Repeat until all the meatballs are snugly wrapped and ready for their buttery glow-up!
Brush each wrapped meatball generously with the melted butter—don’t be shy, full coverage is the secret to that golden, garlicky crust
In a small bowl, stir together the garlic powder, dried parsley, and grated Parmesan until evenly mixed. This is your magic dusting powder—get ready to make these bites absolutely irresistible.
Sprinkle a generous pinch of the garlic-parsley-Parmesan mixture over each buttery bite (the more, the merrier).
Slide the pan into your preheated 375°F oven and bake for 12–14 minutes, until the crescent rolls are puffed, golden brown, and smelling like pure victory. Pull them out, let them cool for just a minute.
Pull them out of the oven while they’re golden and steamy, then serve immediately with a bowl of warm marinara for dunking.
