Preheat oven to 175 degrees.
Dissolve sugar in warm water. Add yeast and stir until dissolved and let sit 3-4 minutes.
Add flour (using only 1-¾ cup if kneading by hand), olive oil, salt, Italian seasoning, 2 Tablespoons parmesan.
Mix on low speed with stand mixer, fitted with dough hook until well mixed and then move to medium speed. Mix (or knead by hand on surface floured with additional ¼ cup flour) until dough pulls away from sides of bowl and forms a ball.
Pat dough to cover bottom of 10 inch iron skillet which has been coated in olive oil.
Turn oven off and place skillet in oven for 20 minutes.
Remove from oven, turning the temperature up to preheat to 375 degrees for convection, or 400 for traditional oven.
Brush with additional 1 Tablespoon of olive oil. Make indentations on surface with fingertip and then sprinkle with additional 1 Tablespoon of Parmesan. Sprinkle with additional herbs if desired.
Bake for 20 minutes or until lightly browned. If desired, sprinkle with coarse kosher or sea salt and brush with additional olive oil.
