01 - In a large mixing bowl, combine the warm water, sugar, and instant yeast. Stir gently and let the mixture rest for about 5 minutes until it becomes frothy and foamy on the surface.
02 - Add the all-purpose flour, salt, and softened butter to the yeast mixture. Stir until a shaggy dough begins to come together, then turn out onto a lightly floured surface.
03 - Knead the dough by hand for 7 to 8 minutes, or use a stand mixer with a dough hook for 5 minutes, until the dough is smooth, elastic, and springs back when pressed.
04 - Transfer the dough to a lightly greased bowl, turning once to coat. Cover tightly with plastic wrap or a clean kitchen towel and place in a warm, draft-free spot until the dough has doubled in size, approximately 1 hour.
05 - Preheat your oven to 400°F. Line a large baking sheet with parchment paper and set aside.
06 - Gently punch down the risen dough to release air bubbles. Divide it into 12 equal portions. Roll each portion into a rope about 7 to 8 inches long and arrange them on the prepared baking sheet, spacing them about 2 inches apart.
07 - Loosely drape a clean kitchen towel over the shaped breadsticks and let them rest in a warm area for 20 to 30 minutes until puffed and nearly doubled.
08 - Bake on the center rack for 12 to 15 minutes, rotating the pan halfway through, until the breadsticks are lightly golden on top and sound hollow when tapped on the bottom.
09 - While the breadsticks bake, whisk together the melted butter, finely minced garlic, salt, and chopped parsley in a small bowl until well combined.
10 - As soon as the breadsticks come out of the oven, generously brush the tops and sides with the garlic butter mixture using a pastry brush. Allow them to cool briefly on the pan, then serve warm.
