01 - In a large bowl, combine the warm water, sugar, and instant yeast. Let the mixture sit until foamy and bubbly, about 5 minutes.
02 - Add the all-purpose flour, salt, and softened butter to the yeast mixture. Stir until a shaggy dough begins to come together.
03 - Turn the dough out onto a lightly floured surface and knead by hand for 7–8 minutes, or use a stand mixer with a dough hook for 5 minutes, until the dough is smooth and elastic.
04 - Place the kneaded dough in a lightly greased bowl, cover with a clean kitchen towel or plastic wrap, and let it rise in a warm spot until doubled in size, about 1 hour.
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. Divide it into 12 equal portions. Roll each piece into a breadstick shape about 7–8 inches long and arrange them on the prepared baking sheet with space between each.
07 - Loosely cover the shaped breadsticks with a kitchen towel and let them rest and puff up for 20–30 minutes.
08 - Bake the breadsticks in the preheated oven for 12–15 minutes, until the tops are lightly golden brown.
09 - While the breadsticks bake, whisk together the melted butter, minced garlic, salt, and chopped parsley in a small bowl.
10 - As soon as the breadsticks come out of the oven, generously brush each one with the garlic butter mixture. Serve warm alongside marinara sauce, soup, or salad.
