In a small bowl, combine the warm water and sugar, stirring until dissolved. Sprinkle the active dry yeast over the surface and let it sit undisturbed for 5-10 minutes until frothy.
In a large mixing bowl, whisk together the all-purpose flour and salt. Create a well in the center and pour in the yeast mixture along with the olive oil.
Stir the mixture with a wooden spoon or your hands until a soft and cohesive dough begins to form. If the dough sticks excessively, gradually add additional flour until manageable.
Lightly flour a clean surface and knead the dough for approximately 5 minutes until smooth and elastic. Shape into a ball and place in a greased bowl. Cover and let rise in a warm area for about 1 hour or until doubled in size.
As the dough rises, preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Once the dough has risen, turn it out onto a floured surface and roll into a rectangle about ½ inch thick. Transfer to the prepared baking sheet.
Brush the top with olive oil, ensuring even coverage. Sprinkle garlic powder, dried oregano, and optional red pepper flakes evenly across the surface.
Generously sprinkle shredded mozzarella cheese over the seasoned dough, pressing down slightly.
Using a sharp knife or pizza cutter, gently score the dough into strips, making cuts deep enough to outline the shape but not cutting all the way through.
Bake in the preheated oven for 12-15 minutes until cheese is bubbly and breadsticks are golden brown.
Remove from the oven and let cool for a few minutes. Garnish with freshly chopped parsley if desired. Slice along the scored lines to separate before serving.
