Does Sour Cream Go Bad?
Sour cream lasts for one to two weeks past its date, and even up to two weeks of opening the container. That’s probably the longest shelf life of all cream-related products.
But to ensure sour cream keeps for as long as possible, you need to store it properly. That’s especially true after you open the container.
On top of that, you still need to know how to tell if your sour cream is bad. You probably know the basics, like the fact that mold is bad, but there’s more to it.
That’s where this article comes in. In it, we go through storage, shelf life, freezing, and going bad of this dairy product.

How To Store Sour Cream
Like other dairy products such as heavy cream or half and half, sour cream needs to be refrigerated. And while the door shelves are a popular place to keep sour cream, it’s definitely not the top choice.
The temperature in the fridge door fluctuates the most, so it’s better to put sour cream somewhere on the bottom shelves and in the back.
I’ve seen online questions about how long sour cream can last out of the fridge, and there isn’t a good answer to such a question. In short, you should put it in the fridge as soon after purchasing as possible.
Once you open the container, make sure it’s always sealed tightly. If it isn’t easily sealable, consider pouring the sour cream in a mason jar or an airtight container.
That’s especially useful if you expect to keep it in the fridge for at least a few days. A tight seal also prevents drying out and keeps any strong odors at bay.
Aluminum foil and a rubber band can work as a makeshift seal.
Since in most cases we don’t use the whole container of sour cream right away, it’s essential to practice proper food hygiene.
That means you should always use clean utensils when scooping sour cream and never double-dip. If you ever need another teaspoon or two for a recipe, just grab a clean spoon or wash the used one.
Using “dirty” utensils will likely transfer bacteria to the sour cream, and that will quite often cause it to spoil early.
Can You Freeze Sour Cream?
Most manufacturers advise against freezing sour cream. Like buttermilk and many other dairy products, sour cream separates once thawed.
While you can regain some of the consistency by whipping it gently, the result won’t be nearly as good as fresh sour cream.
That means that freezing sour cream works only for cooked and baked dishes.
Only use frozen and defrosted sour cream in recipes that require cooking or baking.
If, say, you’re making a soup, the changed texture of sour cream won’t affect it that much because you will stir the dairy product in either way. Similar thing for using thawed sour cream in baking.
When it comes to how to freeze sour cream, consider using an ice cube tray. This way you can easily thaw as much or as little as you need. Plus the frozen cubes end up in a freezer bag, which takes much less space in the freezer than an airtight container.
Of course, if you can’t be bothered with using a tray, you can use a freezer-safe jar or container. Just remember to leave an inch of headspace, as the sour cream slightly expands when frozen.

How Long Does Sour Cream Last
Like other milk-based products, sour cream comes with a sell-by date. That’s how long the store has to sell the package. So it’s quite obvious that the product will be fresh for at least a couple of days longer.
In the case of sour cream, it’s usually about 7 to 10 days past that date. Of course, like almost all dairy products, it’s possible that it will go bad earlier, even before the date on the label.
If your sour cream spoils before its date, it was probably mishandled before it got to the supermarket’s fridge. It’s usually not your fault – don’t worry about it.
When it comes to open sour cream, it can retain freshness for up to two weeks. That’s, of course, if you store it properly. Since sour cream is already sour, it usually retains its quality for longer than other dairy products.
I’ve read in many places online that people regularly store it for a month and it’s still perfectly fine. Feel free to do that, but please remember it’s a bit risky and it’s better to discard sour cream opened for that long.
Also, as usual, the longer it sits in the fridge, the worse its quality.
Let’s sum all of that up.
Sour cream usually lasts for one to two weeks past its date. Once you open the container, it retains freshness for up to two weeks.
| Fridge | |
|---|---|
| Sour cream (unopened) | Sell-by + 1 – 2 weeks |
| Sour cream (opened) | 2 weeks |
Please note that the periods above are estimates and for best quality only.
How To Tell If Sour Cream Is Bad
Signs of spoiled sour cream include:
- Mold, discoloration, or significant change of texture. If there’s lots or water in the container, or anything that’s not supposed to be there, it’s bad.
- Sharp sour or funny smell. Sour smell is normal for sour cream, but if it gets sharp and biting, or off in any other way, it’s time to discard the product.
- Off taste. If everything else seems okay, but the taste is off (e.g., too sour), don’t use that sour cream.
Also, some separation on the surface is perfectly natural, and you can stir it in with a spoon.
See how this looks like:
As usual, if sour cream seems to be perfectly fine, but it sits in the fridge for much longer than the provided estimates, it’s better to throw it out.
If your sour cream has gone bad, and you need something acidic to activate baking soda in a baked good, you can sometimes use buttermilk instead of sour cream. Subbing heavy cream for sour cream, without adding acid such as lemon juice or vinegar, won’t cut it. In soups and casseroles, cream cheese subs in nicely for sour cream.
