01 - In a small bowl, combine warm water, sugar, and yeast. Let sit for 5 to 10 minutes until foamy.
02 - In a large bowl, mix flour and salt. Add the yeast mixture and olive oil. Stir until a shaggy dough forms.
03 - Knead the dough on a lightly floured surface for 6 to 8 minutes until smooth and elastic.
04 - Place the dough in a lightly oiled bowl, cover with a towel, and let rise in a warm area until doubled in size, about 1 hour.
05 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
06 - Punch down the dough and divide it into 16 equal pieces. Roll each piece into an 8-inch rope and tie into a knot, tucking the ends underneath.
07 - Arrange knots on the baking sheet. Cover and let rest for 10 to 15 minutes.
08 - Bake for 12 to 15 minutes until golden brown.
09 - While baking, combine melted butter, garlic, parsley, salt, and pepper.
10 - Brush warm knots generously with garlic butter. Sprinkle with Parmesan if desired. Serve immediately.
