01 - In a large mixing bowl, combine warm water, sugar, and instant yeast. Allow the mixture to rest for approximately 5 minutes until it becomes foamy and bubbly 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 fitted with a dough hook for 5 minutes, until the dough is smooth, elastic, and springs back when gently pressed.
04 - Transfer the dough to a lightly greased bowl, cover with a clean kitchen towel or plastic wrap, and place in a warm, draft-free spot. Let rise for about 1 hour or until doubled in volume.
05 - Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.
06 - Gently punch down the risen dough to release air bubbles. Divide into 12 equal portions and roll each into a rope approximately 7 to 8 inches long. Arrange on the prepared baking sheet, spacing them about 2 inches apart.
07 - Loosely cover the shaped breadsticks with a kitchen towel and let them rest in a warm area for 20 to 30 minutes until puffed and nearly doubled.
08 - Bake in the preheated oven for 12 to 15 minutes, rotating the pan halfway through, until the tops are lightly golden and the bottoms sound hollow when tapped.
09 - While the breadsticks bake, whisk together the melted butter, minced garlic, salt, and chopped parsley. As soon as the breadsticks emerge from the oven, brush them generously on all sides with the garlic butter. Serve warm.
