The Taylor Street Baked Ziti may be stored in the refrigerator for up to 24 hours, or even in your freezer to last for one month. When you're thinking of baking it, make sure and defrost the ziti for a night in the refrigerator, and then remove the casserole from its wrapper and cover it with aluminum foil lightly greased. Then, let the ziti bake on a foil-lined baking tray at 400 degrees F until it is fully cooked in the oven, which will take around 20 to 25 minutes.
