Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper.
In a small bowl, combine the melted butter, minced garlic, chopped parsley, salt, and black pepper. Stir well to create the garlic butter mixture.
Roll out the pizza dough on a lightly floured surface into a large rectangle approximately 12 by 16 inches.
Cut the dough into 1-inch wide strips lengthwise.
Brush each strip generously with the garlic butter mixture.
Cut each strip into 3-inch pieces.
Take each piece and tie it into a loose knot, tucking the ends underneath.
Arrange the garlic knots in a large circle on the prepared baking sheet, forming a wreath shape with the knots touching each other.
Brush the wreath with any remaining garlic butter mixture.
Sprinkle the shredded mozzarella cheese evenly over the wreath, followed by the grated Parmesan cheese.
Bake in the preheated oven for 18 to 20 minutes, or until the bread is golden brown and the cheese is melted and bubbly.
Remove from the oven and let cool for 5 minutes before serving.
