Can You Freeze Cheddar?
Written by Jordan Morley · Reviewed against USDA FoodKeeper · Last updated 28 October 2026
Yes, you can freeze cheddar. Best quality within 6 months; it stays safe beyond that at a constant -18°C.
What freezing does to cheddar
Hard cheese is low in water, so it freezes better than soft cheese, but the texture does go crumbly. Frozen then defrosted, it is fine for cooking, grating and sauces, and less good on a cheeseboard. The FoodKeeper window is 6 months. FoodKeeper gives cheddar a best-quality freezer window of 6 months. For comparison, the same database gives soft cheese 6 months, shredded cheese 3–4 months, butter 6–9 months.

How long: 2 months or 9?
| Source | Freezer time for hard cheese such as cheddar | Texture warning |
|---|---|---|
| Which?, 28 Aug 2025 (UK) | Hard cheese up to 2 months | Soft cheese 'ends up very watery when defrosted' |
| Speciality Food Magazine, 12 Jan 2025 (UK trade) | Use within 6 months | Beyond that 'taste and texture can be very significantly altered'; best used for cooking |
| Healthline, updated 15 Oct 2026 (US) | Indefinitely safe; 'use the cheese within 6–9 months' for best quality | 'Often become crumbly and mealy'; harder to slice |
| President (Lactalis brand site), 2018 | 'Within a few months' | Can become 'crumbly' and lose flavour |
| USDA FoodKeeper (our headline figure) | 6 months | Best quality, not a safety limit |
The UK consumer figure (Which?, 2 months) is a third of the US figure. None of the sources says cheddar becomes unsafe in the freezer; the numbers are about taste and texture. If you want the best result, use it within 2 months; if it has been in longer, use it in cooking.
Block, grated or sliced?
| Format | How to freeze it (as the sources say) | Best use after thawing |
|---|---|---|
| Block | Healthline: portions of no more than about 500g, wrapped, then in an airtight bag to prevent freezer burn. Thaw in the fridge: 7–8 hours per 500g block. | Cooking, sauces, cheese on toast; less good on a cheeseboard |
| Grated | Speciality Food Magazine: divide into sealed freezer bags, remove excess air, date and label. Healthline: shredded cheese can go straight from the bag into the dish without thawing. | Pizza, pasta bakes, cheese sauce, toasties |
| Slices | Speciality Food Magazine: separate the slices with greaseproof paper, then seal in a bag or container. | Toasties and burgers |
Why it goes crumbly
Healthline explains that ice crystals form in the cheese and release water when it thaws, leaving it drier and crumbly. That is why every source steers frozen cheddar towards cooking. Which? says the opposite problem hits soft cheese, which turns watery; soft cheese in a recipe, such as a pasta sauce, freezes better.

Refreezing
Healthline says not to refreeze thawed cheese. That matches our existing advice: freeze in portions you will use in one go.

Common questions
How long can you freeze cheddar?
For best quality, up to 6 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 cheddar?
Cut into portions you will use in one go (smaller blocks defrost more evenly), wrap tightly in cling film or baking paper, then put in a freezer bag. Grated cheese can be frozen loose in a bag.
How do I defrost cheddar?
In the fridge overnight. Use grated cheese straight from frozen.
Can you refreeze cheddar?
Better not to; the texture degrades. Freeze in portions you will use.
Fridge or freezer for cheddar?
The fridge window for cheddar is 6 months (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.
Can you freeze grated cheddar without it clumping?
Speciality Food Magazine says to divide grated cheese into sealed freezer bags and remove the excess air. Healthline says shredded cheese for cooking can go from the bag straight into the dish without thawing. Neither source mentions anti-clumping tricks, so we do not add any.
Why is the UK freezer time for cheddar shorter than the American one?
Which? gives hard cheese up to 2 months; USDA FoodKeeper and Healthline give 6 months or more. The sources do not explain the gap. Both are about quality, so we show both and suggest you use frozen cheddar for cooking either way.
