How Long Does Cottage Cheese Last?
Cottage cheese lasts about 1 week in the fridge after opening. Unopened, use it by the date on the tub. Freezing is not recommended, and it should never sit out for more than 2 hours.
Cottage Cheese — opened
shelf life- Unopened: 1–2 weeks in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Cottage cheese is a fresh, unaged cheese of loose milk curds in a lightly salted cream dressing. It is wet, mild and barely acidic compared with yogurt, so it has little natural protection and is one of the quickest dairy foods to spoil. Once the seal is broken it sours, turns bitter and grows mold within days.
How to store cottage cheese
- Serve cottage cheese into a bowl with a clean spoon instead of eating out of the tub, since saliva enzymes and bacteria thin it and spoil it fast.
- Reseal the lid firmly and keep the tub at the back of the lowest shelf, the coldest spot in most refrigerators.
- Stir pooled liquid back into the curds before closing the tub, so the top layer of curds does not dry out.
- Buy a container size you will finish within a week; the large tub is only a bargain if it all gets eaten.
How to tell if cottage cheese has gone bad
- A sour, yeasty or musty smell; fresh cottage cheese smells clean and faintly milky.
- A bitter or sharply sour taste, or curds that feel slimy rather than soft.
- Pink, yellow or green discoloration, or fuzzy mold on the surface or under the lid.
- A swollen lid, or a large amount of separated, watery liquid with shrunken, gritty curds.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
How long is cottage cheese good for after opening?
Cottage cheese is good for about 1 week after opening, kept at 40°F (4°C) or colder. This holds even if the printed date is further off, because that date only applies to the sealed tub. Marking the lid with the opening date removes the guesswork.
Can you eat cottage cheese past the expiration date?
It is best not to go more than a few days past it, and only if the tub is unopened and has always been cold. Cottage cheese has less acid and more moisture than yogurt or sour cream, so it has less margin. Signs of spoilage mean discard, but a normal smell does not prove safety.
Why is my cottage cheese watery?
A little thin liquid is normal: whey drains from the curds as the tub sits, especially after some has been scooped out. Stir it back in. If the liquid is excessive and the curds are slimy, gritty, sour-smelling or discolored, the cottage cheese has spoiled and should be thrown away.
Can cottage cheese be frozen?
Freezing cottage cheese is safe but not recommended. The curds break down and turn mushy and watery on thawing, and the cream dressing separates. If you have a surplus, it is acceptable only blended into cooked dishes such as lasagna, pancakes or baked casseroles, within about 3 months.
