Preheat the oven to 400 degrees F and line a baking sheet with parchment paper.
Unroll the pizza dough on a lightly floured surface and cut it into 8 equal strips.
Tie each strip into a simple knot and place the knots on the prepared baking sheet.
Stir the melted butter, minced garlic, dried parsley, and salt together in a small bowl.
Brush the garlic butter mixture evenly over each knot.
Bake for 12 to 15 minutes until the knots turn golden brown.
Warm the marinara sauce in a small saucepan or microwave while the knots bake.
Transfer the baked knots to a serving plate, sprinkle with Parmesan cheese, and serve with the warm marinara for dipping.
