Preheat the oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.

1. Prepare the dough: If using store-bought pizza dough, roll it out onto a lightly floured surface into a rectangle or square about 1/2 inch thick. Cut the dough into strips about 1 inch wide.
2. Form the knots: Take each strip of dough and tie it into a knot. Place the knots on the prepared baking sheet, leaving a little space between each one. If the dough is too sticky, you can lightly flour your hands.
3. Make the garlic butter: In a small bowl, combine the melted butter, minced garlic, dried oregano, garlic powder, and red pepper flakes (if using). Stir to combine.
4. Brush the knots: Brush the garlic butter generously over each garlic knot, making sure to coat them well. Reserve some butter for brushing the knots after baking.
5. Bake: Bake the garlic knots in the preheated oven for 12-15 minutes, or until they are golden brown and cooked through.
6. Add finishing touches: Once baked, remove the garlic knots from the oven and brush them with the remaining garlic butter. Sprinkle with freshly grated Parmesan cheese, if using, and garnish with freshly chopped parsley.
7. Serve: Serve the garlic knots warm with marinara sauce or your favorite dipping sauce.
