Preheat the oven to 375°F and line two baking sheets with parchment paper.
Lightly flour your work surface then using a rolling pin, roll out the dough into a 10-inch square. (If needed, the dough can also be pulled and stretched with your hands.)
Using a sharp knife or pizza wheel, cut the square in half to form two rectangles then cut each rectangle widthwise into 12 strips.
Tie each strip into a knot then arrange the knots on the lined baking sheets.
Bake the knots for 7 minutes, then rotate the baking sheets and bake an additional 5 to 10 minutes until the knots are baked through.
While the knots bake, combine the minced garlic, olive oil and butter in a small sauce pan set over medium-low heat. Cook the garlic butter, stirring, until the garlic just begins to turn golden brown. Remove the mixture from the heat and stir in the chopped parsley.
Remove the knots from the oven and immediately brush them with the garlic mixture. Sprinkle them with the grated Parmesan cheese and a pinch of salt and serve warm with marinara sauce for dipping (optional).
