Pizza dough can be frozen before baking it. Take enough dough for one pie and form it into a semi-flat disk shape. You don't have to spread it all the way out, just enough to make it into a circle an inch or two high. Spray the inside of a zip-top bag with some cooking oil spray and pop the dough in the bag. Lay it flat and place in your freezer. To use, simply take the dough out of the freezer and remove it from the bag. Place it on a floured surface and let it rest for about two hours or until it is completely thawed and pliable. Form it into your crust and bake as usual. You can also place the frozen dough in your refrigerator the day before you want to make your pizza. Dough can last in the freezer for up to three months. This is great when you are short on time, but still want a freshly baked pizza right from your oven.
