Place the warm water, yeast, and ½ tablespoon of sugar into a small bowl, and stir together. Let sit for 5-10 minutes until foamy, and the yeast is activated.
To the bowl of a stand mixer fitted with the hook attachment add the remaining 3 tablespoons of sugar, 3 cups of flour, and salt. Mix to combine.
Add the activated yeast mixture and oil to the bowl. Mix on medium-low speed until a dough starts to form, scraping down the sides as needed. Continue to mix until the dough starts to clean the sides of the bowl. If it is not cleaning the sides, begin to add 1 tablespoon of flour at a time until it does (up to ½ cup more flour total).
Once the sides of the bowl are being cleaned by the dough, turn the stand mixer speed ti medium-high. Knead for 7 minutes until a smooth dough forms.
Lightly spray a large bowl with non-stick cooking spray. Place the dough in the bowl and roll it around so the dough is coated in oil. Cover with plastic wrap and allow the dough to rest until doubled in size, about 1 to 1 ½ hours.
Spray two baking sheets with non-stick cooking spray and set aside.
Transfer the breadstick dough to a lightly floured work surface and punch it down to release any air bubbles. Divide the dough into 2-ounce portions. Roll each portion into a ball. (I got 15 pieces, but amounts may vary depending on how much flour is used.)
Roll each dough ball into a long rope and then place them on the prepared baking sheets, so that they are not touching. Cover the breadsticks with a clean kitchen towel and allow them to rise again until doubled in size for 1 to 1 ½ hours.
Preheat your oven to 400 degrees F.
In a small bowl, stir together the butter, garlic powder, salt, and Italian seasoning. Brush the breadsticks with half of the garlic butter.
Bake for 11-14 minutes until golden brown.
Remove from the oven and immediately brush the breadsticks with the remaining butter mixture. Sprinkle the parmesan cheese over top and serve warm.
Notes
These breadsticks are best served warm. You can re-warm them in the oven for a couple of minutes or in the microwave at 15-second intervals.
Store any leftovers at room temperature for up to 3 days, in the fridge for up to 1 week, or freeze for up to 3 months.
