Pour yeast into a small bowl. Add the ½ cup warm water and sugar. Stir together. Let sit for 10 minutes.
Once yeast is foamy, combine flour and salt and mix wet mixture into dry ingredients.
Mix well with silicone spatula until a sticky dough forms. Continue to mix with spatula for 2-3 minutes. Then roll dough out on floured surface.
Knead with floured hands for 10 minutes. If the dough is hard to work with, dust with additional flour. Using only a tiny bit at a time so it doesn't dry out. The dough is ready when it is relatively smooth and no longer sticking to your hands. You can use a mixer for this as well and the same principle applies.
Form dough into a ball and transfer into lightly greased large bowl. Set bowl in a warm location, cover and let rise for one hour.
Transfer dough onto floured surface and use a rolling pin to roll out into a rectangle. Cut lengthwise into six long pieces (a pizza cutter makes this super simple). Cut once more in the middle to create 12 breadsticks.
Place breadsticks on a lightly greased cookie sheet. Let rise for 1 hour.
Preheat oven to 450 degrees. Melt butter and brush over breadsticks. Bake for 20 minutes. Remove from oven, brush with reserved melted butter. Bake for remaining 5 minutes. Remove from oven and cool.
Notes
I highly recommend using a pizza cutter to form the dough into breadstick shapes. You can roll it by hand, but the pizza cutter will get the job done in seconds!Don't rush the sugar, warm water, and yeast. Letting it rest for 10 minutes will make it bubbly and the breadsticks will turn out good. Kneading the dough with your hands is going to give you the most delicious results.
How to Proof Dough in Instant Pot
Assemble your dough as you would, and then grease your Instant Pot liner.
Add in the dough and place a glass lid on top of your Instant Pot. Select the yogurt setting and let it rise for 30 minutes. Remove dough and then move on to the next steps in the recipe.
This only works with the Yogurt setting. All other settings are too hot and will cook the dough.
