01 - In a large bowl, dissolve sugar and yeast in warm water. Allow to sit for 5 to 10 minutes until foamy.
02 - Add olive oil, salt, and 2 1/2 cups of flour to the yeast mixture. Stir until a shaggy dough forms, then gradually incorporate remaining flour as needed.
03 - On a floured surface, knead the dough for 5 to 7 minutes until smooth and elastic.
04 - Transfer dough to a lightly oiled bowl, cover, and let rise in a warm area for 1 hour until doubled in size.
05 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
06 - Punch down the dough and divide into 12 equal portions. Roll each piece into a 10-inch rope and tie into a loose knot.
07 - Arrange knots on the prepared baking sheet, cover loosely with a towel, and let rest for 10 minutes.
08 - Combine melted butter, minced garlic, chopped parsley, and salt in a small bowl.
09 - Generously brush knots with the garlic butter mixture.
10 - Bake knots for 16 to 18 minutes until golden brown.
11 - Immediately brush knots with remaining garlic butter, then sprinkle with Parmesan cheese and extra parsley if desired. Serve warm.
