You can easily freeze cheese in your freezer, so if you find that killer deal on cheese (Costo usually has great deals) or are buying cheese close to the best before date, you can easily freeze it for use later.
If you are using cheese for cheese sauce, pasta noodles, etc, grate the cheese first or cut it into cubes, then freeze in a ziploc. As it freezes, remove it from the freezer a few times to shake it, so the cheese doesn’t stick together as it freezes. This way, you can grab just as much cheese as you need.
If you would like to freeze it in blocks, do note that the cheese will change texture slightly. So it will be fine for grilled cheese, for example, but not as good for cheese and crackers. Wrap the cheese well in foil or plastic wrap, wrapping as tightly as possible to prevent air reaching the cheese. Then place in a ziploc bag, squeezing as much air as possible.
If you own a Food Saver, you can vacuum seal the cheese for best results – and vacuum sealing it can also mean your cheese can last much longer in the fridge without freezing.
Cheese will stay good for up to 3 months, but will be best if used within a month.
