Keep it on a middle shelf, not the door: the door warms up every time it opens.
Sour cream shelf life, answered
How long does sour cream last in the fridge?
Use-by date at 4°C (40°F) or colder. Count from the day it was cooked, opened or bought.
How long does sour cream last in the freezer?
Not recommended. Freezing sour cream is not recommended; texture breaks down or the result is unsafe to rely on.
How long does sour cream 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 is sour cream good for past the expiration date?
For perishable sour cream, the storage clock matters more than the label: if it has been in the fridge longer than use-by date, discard it even before the printed date.
How can you tell if sour cream is bad?
Sour or cheesy smell when it should be clean and mild. Lumps, curdling or a thick, slimy body. Yellowing or a pink, green or grey tinge.
How long can sour cream sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.

Sour or cheesy smell when it should be clean and mild.

Can you freeze sour cream?
Sour cream left out overnight
Sour cream 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 sour cream
Best-by and sell-by
FoodKeeper gives unopened sour cream use-by date 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.
Past the date
For perishable sour cream, the storage clock matters more than the label: if it has been in the fridge longer than use-by date, discard it even before the printed date.
How to store sour cream
- Store on an inside shelf, not the door, at 40°F (4°C) or below.
- Close the container tightly; dairy absorbs fridge odours.
- Pour what you need and return it to the fridge right away.
