Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.

Let the pizza dough sit at room temperature for about 10 minutes. Sprinkle a clean work surface with flour.

Roll each piece of dough into an 8-inch long rope and snip the ends to create a bone shape.

Transfer the shaped breadsticks onto the lined baking sheets, ensuring enough space between each.

Brush melted butter over each breadstick and sprinkle grated Parmesan cheese on top.

Bake for 15 minutes until puffed and golden in color.

Add shredded mozzarella cheese on top and return to the oven for 5 to 7 minutes until melted.

Let cool slightly before serving with marinara sauce.
