If you're using a cast-iron skillet, there is no need to pre-bake pizza crust, as it cooks it evenly and on all sides. However, if you're cooking your pizza on a baking sheet, it's best to pre-bake the dough for 4-5 minutes to ensure your thin crust will be perfectly cooked later. This will ensure your crust will not get soggy after adding the marinara sauce.
