Yes, you can! Most cheesecakes freeze well, and this one is no exception. Just make sure you wait until it's completely cool. I'd keep it in the pan and wrap really well before freezing. Alternatively, if you don't want your pan to be in the freezer for weeks on end, carefully take the cheesecake out of the pan but keep it in the baking paper. Wrap with several more layers of cling wrap/aluminium foil and freeze for up to 1 month. You can freeze it for longer than a month if you like, but I think cheesecakes begin to deteriorate in taste and texture after this.
