Cheesecake freezes surprisingly well. Typically made with cream cheese, eggs and sugar, cheesecake tends to be rich and heavy. As a result, you may find yourself with more cheesecake than you can eat. Or, you may want to make it ahead for a special event. Keep the cheesecake in the freezer for no more than a month and you probably won't notice any decline in taste or texture.
Cut out a piece of heavy cardboard that's the same size as the cheesecake. Wrap it in aluminum foil.
Lay a sheet of plastic wrap onto a large, flat surface, such as a counter, then lay the piece of foil-wrapped cardboard on top of the plastic wrap.
Slide the cheesecake carefully off the plate or pan onto the piece of foil-wrapped cardboard. If you are freezing a cheesecake that you just removed from the oven, place the entire pan into the freezer for about an hour to make the cheesecake easier to transfer before you complete this step.
Fold the plastic wrap up to completely cover the the cheesecake. This will also gently attach the cheesecake to the piece of foil-wrapped cardboard, keeping it intact. Wrap the entire bundle in another layer of plastic wrap. For more protection, put the wrapped cheesecake into a plastic freezer bag, then seal this bag.
Put the cheesecake into the freezer.
