In a deep bowl cover dry yeast with warm water and stir it.
Pour olive oil to the bowl, sprinkle salt with sugar. Mix. Let the mixture sit for 5 minutes. This time will be enough for the yeast to start reacting.
Start adding flour in bunches. At first, I tend to use a spoon for mixing and when the dough becomes thicker, I will continue kneading with hands.
In the end, you should get a thick malleable dough. Cover it with a kitchen towel and place the bowl in a dark warm place for an hour.
If you followed all the instructions, then the dough should double in size. Now is also the time to shred parmesan. You can use graters of different sizes.
Add grated cheese to the dough and thoroughly knead it once again. Leave it once again for 1 hour.
Preheat oven at 350ºF/180°C. Tear off small portions of dough from the main piece. Roll up strips with a thickness as a pencil, 20-25 cm long.
Spread parchment paper over the baking tray and place strips of dough with some space between them. Let the tray sit for 15 minutes at the room temperature before baking. Bake parmesan breadsticks for 20 minutes. Let grissini sticks cool down before serving. Enjoy your meal!
