Keep parbaked pizza shells on hand for quick weeknight meals. Roll the dough balls into rounds and bake on a preheated pizza stone or baking sheet at 500 degrees F for about 10 minutes for a softer crust, about 15 minutes for a crisper crust. Remove and let cool. Wrap the pizza shells well and freeze for up to 1 month. When ready to serve, add your favorite toppings to the frozen pizza shell and bake on a preheated pizza stone or baking sheet at 500 degrees F until hot.
