01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Unroll the crescent roll dough and separate into 8 triangles along the perforated lines.
03 - Combine mozzarella, cheddar, and Parmesan cheeses in a small bowl until evenly blended.
04 - Place approximately 2 tablespoons of cheese mixture at the wide end of each triangle.
05 - Roll each triangle from the wide end toward the tip, enclosing the cheese completely. Tuck the tip underneath to seal.
06 - Place rollups on the prepared baking sheet, seam-side down, leaving space between each for even baking.
07 - Whisk together melted butter, minced garlic, parsley, and salt until fully combined.
08 - Generously brush each rollup with the garlic butter mixture, coating the tops completely.
09 - Bake for 15–18 minutes until deep golden brown and cheese is visibly bubbly.
10 - Remove from oven, brush with additional garlic butter if desired, and serve immediately while warm.
