Chicago Deep Dish Pizza is classically baked in a well greased cast iron skillet. I don't have two 9" cast iron skillets in my house! If you don't have them too, then you can substitute two well greased 9" cake pans. Just watch the crust to be sure that it doesn't brown too quickly. If that happens, turn the oven down to 400 for the last 15 minutes of the cook time.
You can turn any extra dough and trimmings into rolls, just make 2 inch balls, place on a baking sheet and bake at 450F for 15 minutes.
