Preheat the oven to 375 degrees F and line a baking sheet with parchment paper.
Open the tube of dough and separate into individual breadsticks. Place them on the prepared baking sheet with space between each one.
Stir together the melted butter, minced garlic, chopped parsley, and salt in a small bowl until combined.
Brush the garlic butter mixture evenly over the top of each breadstick.
Bake for 12 to 15 minutes until the breadsticks turn golden brown.
Remove from the oven and serve warm with the marinara sauce on the side for dipping.
