Yes, you can freeze grated cheddar or mozzarella. Best quality within 3–4 months; it stays safe beyond that at a constant -18°C.
What freezing does to grated cheddar or mozzarella
Shredded cheese is one of the easiest things to freeze: it is already in small pieces, so it freezes loose and can be used straight from frozen. The FoodKeeper window (3–4 months) is shorter than for a block because the shreds have more surface exposed to air. FoodKeeper gives grated cheddar or mozzarella a best-quality freezer window of 3–4 months.

Common questions
How long can you freeze grated cheddar or mozzarella?
For best quality, up to 3–4 months (USDA FoodKeeper). It stays safe beyond that, because bacteria cannot grow at a constant -18°C; the time limit is about taste and texture, not safety. Label the pack with the date so you can use the oldest first.
How should I freeze grated cheddar or mozzarella?
Spread on a tray for an hour so the shreds do not clump, then bag with the air pressed out.
How do I defrost grated cheddar or mozzarella?
Use straight from frozen on pizza, in sauces and in bakes; no defrosting needed.
Can you refreeze grated cheddar or mozzarella?
Not needed; just take out what you want from the bag.
Fridge or freezer for grated cheddar or mozzarella?
The fridge window for grated cheddar or mozzarella is 1 month (USDA FoodKeeper). If you are not going to finish it inside that window, freeze it while it is still fresh, ideally in the first day or two, since freezing only pauses the clock and anything frozen late goes in with less life left.
