Preheat your oven to 425°F. Lightly grease a 9x13-inch baking dish with 2 tablespoons of melted butter.

On a floured surface, roll out the pizza dough to fit the baking dish, then gently stretch it to cover the bottom.

Combine Parmesan, garlic powder, Italian seasoning, dried oregano, onion powder, and salt in a bowl.

Using a pizza cutter, score the dough into 16 even pieces to form breadsticks.

Place in the preheated oven and bake for 15 to 18 minutes, until the edges turn golden.

Immediately after baking, brush the breadsticks with the remaining melted butter and sprinkle evenly with the seasoning mix. Let cool for about 5 minutes. Serve warm with marinara sauce if desired.
