01 - In a large bowl, dissolve active dry yeast and granulated sugar in warm water. Allow the mixture to sit for 5 minutes, until frothy.
02 - Incorporate all-purpose flour, salt, and olive oil into the yeast mixture. Stir until a soft dough develops.
03 - Transfer dough onto a floured surface and knead for 5 to 7 minutes until smooth and elastic.
04 - Place dough in a lightly oiled bowl, cover, and set aside in a warm area for 1 hour, or until doubled in volume.
05 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
06 - Deflate risen dough and section into 12 equal portions. Roll each into a 7-inch breadstick.
07 - Position breadsticks on the prepared baking sheet, ensuring slight spacing between each.
08 - In a small bowl, combine melted unsalted butter, minced garlic, onion, chopped parsley, and salt until uniform.
09 - Apply half of the garlic-onion butter evenly over the uncooked breadsticks using a pastry brush.
10 - Bake in the preheated oven for 13 to 15 minutes until breadsticks are golden brown.
11 - Remove breadsticks from oven and immediately coat with remaining garlic-onion butter.
12 - Serve breadsticks warm.
