Where to store cottage cheese
Keep it on a middle shelf, not the door: the door warms up every time it opens.
Cottage cheese shelf life, answered
How long does cottage cheese last in the fridge?
1 week at 4°C (40°F) or colder (opened). Count from the day it was cooked, opened or bought.
How long does cottage cheese last in the freezer?
Not recommended. Freezing cottage cheese is not recommended; texture breaks down or the result is unsafe to rely on.
How long does cottage cheese last at room temperature?
No more than 2 hours, or 1 hour above 32°C (90°F). Perishable food left out longer should be thrown away.
How long does cottage cheese last after opening?
1 week in the fridge once opened. The printed date stops applying the moment you break the seal.
How long does unopened cottage cheese last?
2 weeks in the fridge, if the seal is intact and it is stored as the label says.
How long is cottage cheese good for past the expiration date?
FoodKeeper gives unopened cottage cheese 2 weeks in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
How can you tell if cottage cheese is bad?
Ammonia or a sharp sour smell beyond the cheese's usual aroma. Slimy surface, or very dry and cracked all the way through. Darkened or yellowed edges, or new colours that are not part of the cheese.
How long can cottage cheese sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.
Signs cottage cheese has gone bad
Smell
Ammonia or a sharp sour smell beyond the cheese's usual aroma.
Texture
Slimy surface, or very dry and cracked all the way through.
Colour
Darkened or yellowed edges, or new colours that are not part of the cheese.
Mould
On hard cheese, cut 1 inch around the spot. On soft or shredded cheese, discard.
Can you freeze cottage cheese?
Cottage cheese left out overnight
Cottage cheese left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
Bacteria multiply fastest between 4 °C and 60 °C (40–140 °F).
Best-by and use-by dates on cottage cheese
