The shelf life of sour cream is influenced by various factors, including pasteurization and storage.

Hey there! This site is reader-supported and I earn commissions if you purchase products from retailers after clicking on a link from this site.

Pasteurization, which heats the cream to eliminate harmful bacteria, significantly extends the longevity of commercially produced sour cream, allowing it to last longer than unpasteurized varieties.

The expiry date on the container provides a guideline for its optimal quality, with properly refrigerated, unopened sour cream often lasting up to two weeks beyond this date.

To further ensure the maximum shelf life and maintain taste and texture, sour cream should be stored in the refrigerator in an airtight container, avoiding prolonged exposure to room temperature or other food odors, and consumed within a week to ten days after opening.

Other Factors Affecting Longevity

A few other things can impact the longevity of sour cream:

  1. Fat content: Sour cream with a higher fat content tends to have a longer shelf life compared to low-fat or fat-free varieties. The fat acts as a natural preservative, slowing down bacterial growth.
  2. Additives: Some commercial sour cream brands may include stabilizers or preservatives that can extend the product’s shelf life. However, it’s always a good idea to check the ingredients list and opt for minimally processed options when possible.
  3. Contamination: Introducing contaminants, such as dirty utensils or fingers, into the sour cream container can introduce bacteria and accelerate spoilage. Always use clean utensils when scooping out sour cream and avoid double-dipping.

How Long Past Expiration Date Can You Use Sour Cream?

Assuming that you kept your container refrigerated at least 40 degrees Fahrenheit, you can expect your sour cream to last anywhere from 1-3 weeks past expiry. Again, this depends on several factors such as contamination and ingredients, so it’s not set in stone.

With that said, if you notice any signs of deterioration such as mold, an off smell, or an off taste, you should throw your sour cream and buy a fresh container.

Signs Sour Cream is Bad

As much as we love sour cream, it’s not invincible. Despite our best efforts, sometimes things can go awry.

With most things, sour cream will develop an unfamiliar look, taste, and smell after spoiling. Here are some easy signs to look out for:

  1. If you notice that your sour cream has become yellow or discolored in any way, discontinue use.
  2. If you notice mold on sour cream, it is yet another sign of spoilage.
  3. Sour cream that doesn’t taste or smell quite right is also likely unsafe to eat.
  4. And most importantly, if your sour cream has gone 1-3 weeks past expiry, it is best you toss it and purchase fresh sour cream.

If you find that your sour cream has gone bad, you can replace the sour cream with buttermilk in the case of dressings or baked goodies. Although the two seem very different, they are very similar when you compare buttermilk vs sour cream.

Visual Cues

One of the first things to look out for when assessing the freshness of your sour cream is its appearance. Fresh sour cream should have a smooth, creamy texture and a pristine white color. If you notice any signs of discoloration, such as yellowing or browning, it’s a clear indication that the sour cream has started to spoil.

Another visual red flag is the presence of mold. If you spot any fuzzy green, blue, or gray patches on the surface of the sour cream, it’s time to bid it farewell. Mold can spread quickly throughout the container, even if it’s only visible on a small portion of the surface.

The Nose Knows

Your sense of smell is a powerful ally when it comes to detecting spoiled sour cream. Fresh sour cream should have a slightly tangy, buttery aroma. If you take a whiff and are greeted by a strong, unpleasant odor reminiscent of sourness or even a rancid smell, it’s a surefire sign that the sour cream has gone bad.

Trust your nose—if something smells off, it’s best to err on the side of caution and discard the sour cream rather than risk consuming it.

Last Resort Taste Test

If the sour cream looks and smells okay, but you’re still unsure about its freshness, you can cautiously perform a taste test. However, this should be done with great care and only if you’re confident that the sour cream hasn’t spoiled based on the previous visual and olfactory checks.

Take a small amount of sour cream on a clean spoon and give it a taste. If it has a noticeably sour, bitter, or off-putting flavor, it’s time to toss it out. Remember, even if the taste is only slightly off, it’s not worth risking your health by consuming potentially spoiled sour cream.

How to Properly Store Sour Cream

Proper storage is key to extending the shelf life of your sour cream and keeping it fresh for as long as possible. A little extra care and attention go a long way in maximizing the life of such a versatile dairy product.

Keep It Cool

The golden rule of sour cream storage is to keep it refrigerated at all times. As soon as you bring it home from the grocery store, make sure to tuck it away in the fridge. The ideal storage temperature for sour cream is 40°F (4°C) or below, which helps slow down bacterial growth and keeps the cream from spoiling too quickly.

When you’re not using the sour cream, keep it in the coldest part of your refrigerator, typically the back of the top shelf or the bottom shelf. Avoid storing it in the door, as the temperature there tends to fluctuate more due to frequent opening and closing.

Seal It Tight

Another important aspect of sour cream storage is keeping it in an airtight container. Once you’ve opened the original packaging, transfer any leftover sour cream to a clean, airtight container before returning it to the fridge. This helps prevent the sour cream from absorbing odors from other foods in the refrigerator and also minimizes its exposure to air, which can cause it to dry out or develop mold more quickly.

If you prefer to keep the sour cream in its original container, make sure to seal it tightly with the lid or with plastic wrap to create an airtight seal.

Avoid Contamination

To further extend the shelf life of your sour cream, it’s crucial to avoid contamination. Always use clean utensils when scooping out sour cream, and never double-dip. Introducing contaminants, such as dirty spoons or fingers, can introduce bacteria into the sour cream and accelerate spoilage.

If you’re serving sour cream at a party or buffet, consider transferring a portion to a separate serving bowl and replenishing it as needed, rather than letting guests dip directly into the main container. This helps minimize the risk of contamination and keeps your sour cream fresh for longer.

Don’t Let It Linger

While sour cream can last for a while in the fridge, it’s not invincible. To enjoy it at its best, try to use it within a week to ten days after opening. If you find yourself with more sour cream than you can use in that timeframe, consider sharing it with friends or family, or get creative in the kitchen and whip up a batch of tangy salad dressing, zesty dip, or moist baked goods.

Tips to Keep Sour Cream Fresh for Longer

Proper storage is just the beginning. There are a few extra tricks that can come in handy that you should also know.

Give It a Stir

One simple yet effective tip for prolonging the life of your sour cream is to give it a good stir before storing it in the fridge. This helps redistribute any separation that may have occurred during storage and keeps the texture smooth and consistent.

After opening a new container of sour cream, use a clean spoon to give it a thorough mix, making sure to incorporate any liquid that may have separated from the solids. This quick step can help prevent the formation of dry or crusty bits on the surface, which can lead to faster spoilage.

Invest in Quality Containers

While the original packaging of your sour cream may suffice for storage, investing in high-quality, airtight containers can take your preservation game to the next level. Look for containers with tight-fitting lids that create a secure seal, preventing air and other contaminants from entering.

Glass or ceramic containers are excellent choices, as they are non-porous and won’t absorb odors or flavors from other foods in the fridge. If you prefer plastic, opt for BPA-free options that are designed for food storage.

Practice Proper Hygiene

In addition to using clean utensils when scooping out sour cream, it’s important to maintain good hygiene practices throughout the storage process. Always wash your hands thoroughly before handling the container or its contents to minimize the risk of introducing bacteria.

If you’re transferring sour cream to a separate container, make sure it’s been washed with hot, soapy water and dried completely before use. This helps prevent any lingering bacteria or moisture from contaminating your sour cream.

Keep It Cool and Consistent

Temperature fluctuations can wreak havoc on the shelf life of your sour cream, so it’s crucial to keep it stored at a consistent temperature. Avoid placing your sour cream near the front of the fridge or in the door, where the temperature tends to be less stable due to frequent opening and closing.

Instead, store your sour cream in the back of the fridge, where the temperature is typically the coldest and most consistent. If you have a particularly cold spot in your fridge, like the back of the bottom shelf, consider making that your sour cream’s designated home.

Get Creative with Leftovers

If you find yourself with a surplus of sour cream nearing its expiration date, don’t let it go to waste! Get creative in the kitchen and whip up a batch of tangy ranch dressing, creamy potato salad, or zesty enchiladas.

You can also portion out leftover sour cream into smaller, airtight containers and freeze them for later use. While the texture may change slightly upon thawing, frozen sour cream is still perfect for use in cooked dishes or baked goods.

Can You Freeze Sour Cream?

Freezing sour cream can be a great way to extend its shelf life and reduce food waste. When you find yourself with an abundance of sour cream that you can’t use up before its expiration date, you can freeze sour cream!

However, it’s important to keep in mind that the texture and consistency of the sour cream will change once it’s been frozen and thawed.

How to Freeze Sour Cream

  • Start by transferring it to an airtight, freezer-safe container. If you’re freezing a large quantity, consider dividing it into smaller portions so you can thaw only what you need later on.
  • Be sure to leave some headspace in the container to allow for expansion as the sour cream freezes.
  • Label the container with the date and amount of sour cream, then place it in the freezer.

Sour cream can be kept frozen for up to six months, although it’s best to use it within three months for optimal quality.

Texture Changes

When you’re ready to use your frozen sour cream, transfer the container to the refrigerator and allow it to thaw gradually. This process can take several hours or even overnight, depending on the quantity of sour cream.

Once thawed, you’ll notice that the texture of the sour cream has changed. It may appear separated, with liquid on top and a chunky, cottage cheese-like consistency below. This is because the freezing process causes the water and fat in the sour cream to separate.

While the texture change may make thawed sour cream less appealing for use, it’s still perfectly fine to use in cooked dishes or baked goods. The heat from cooking or baking will help to re-incorporate the separated liquid and solids, resulting in a smoother consistency.

Thawed sour cream is an excellent addition to casseroles, soups, stews, and sauces. It can also be used in baked goods like cakes, muffins, and biscuits, where its slightly altered texture won’t be as noticeable.

If you want to use thawed sour cream as a topping or dip, you can try blending it in a food processor or whipping it with an electric mixer to help smooth out the texture. However, keep in mind that it may not be quite as smooth and creamy as fresh sour cream.

Alternative Uses for Expired Sour Cream

Just because your sour cream has expired doesn’t mean it has to go straight into the trash. There are some creative ways you can put that expired dairy to good use.

Compost Companion

If you’re an avid gardener, you know that compost is the key to healthy, thriving plants. Did you know that expired sour cream can be a valuable addition to your compost pile? The dairy content provides beneficial bacteria that help break down organic matter, while the fat acts as a food source for microorganisms.

Simply add your expired sour cream to your compost bin along with other organic materials like fruit and vegetable scraps, coffee grounds, and dry leaves. Over time, these ingredients will decompose, creating nutrient-rich compost that your plants will love.

Soothing Skin Treatment

Believe it or not, expired sour cream can be a secret weapon in your beauty routine. The lactic acid in sour cream acts as a gentle exfoliant, helping to remove dead skin cells and reveal smoother, brighter skin.

To create a nourishing face mask, mix equal parts expired sour cream and honey, then apply the mixture to your face and neck. Let it sit for 10-15 minutes before rinsing off with lukewarm water.

Garden Pest Deterrent

If pesky aphids or other insects are wreaking havoc on your garden, expired sour cream may be the solution you’ve been looking for. The dairy content can help deter certain pests, while also providing a source of moisture for your plants.

Dilute a small amount of expired sour cream with water, then pour the mixture around the base of affected plants. The sour cream will create an uninviting environment for pests, while also nourishing the soil as it decomposes.

Leather Conditioner

Got an old leather couch or pair of shoes that could use some TLC? Expired sour cream to the rescue! The lactic acid in sour cream can help soften and condition leather, making it look and feel like new again.

Apply a small amount of expired sour cream to a clean, damp cloth, then gently rub it into the leather in circular motions. Let it sit for 10-15 minutes, then wipe away any excess with a clean cloth.

DIY Silver Polish

If your silver jewelry or cutlery is looking a bit tarnished, expired sour cream can help restore its shine. The lactic acid in the cream helps to break down tarnish, making it easier to buff away.

Apply a small amount of expired sour cream to a clean cloth, then gently rub it onto the tarnished silver. Let it sit for a few minutes, then rinse the silver with warm water and dry it thoroughly.

Can You Use Spoiled Sour Cream For Baking?

It’s best to avoid eating spoiled sour cream if it has been 1-3 weeks past expiry.

Despite being in baked goods, the spoiled sour cream can still induce food poisoning and unwanted symptoms when consumed. Thus, it is best to avoid using sour cream 1-3 weeks after the printed expiration date, even when using it to bake.

Is your sour cream getting close to its expiration date?

Don’t worry.

Although we don’t recommend using old sour cream, you can quickly use up sour cream that is ready to expire. Whether you prefer cooking vs baking with sour cream, or somewhere in between, we are willing to bet you can find a recipe you love to help you use up that leftover sour cream in your refrigerator.

Can You Get Sick From Expired Sour Cream?

It is important to know that you can, indeed, get sick from expired sour cream.

But how long it has been expired and what conditions it was kept in makes a difference.

Because sour cream is a dairy product, you can get sick from it rather easily if it isn’t stored properly or goes bad. Consuming expired sour cream can cause you to get food poisoning.

Expired Sour Cream: To Use or Not to Use?

Sour cream remains a worldwide favorite for many. It is a cool and creamy complement to many dishes. Remember that sour cream that lasts anywhere from 1-3 weeks past its expiration date assuming that it was refrigerated continuously.

If you notice signs of spoilage including discoloration, a bad smell, or mold growth, you should pitch the sour cream. Purchase fresh sour cream instead.

Soured Cream Expiry FAQs

What Can You Do with Expired Sour Cream?

You can do what you want with expired sour cream, but remember, once the sour cream goes 1-3 weeks past expiry, you should no longer continue with the use. 

Will Mold on Sour Cream Hurt You?

Depending on your level of sensitivity to mold, mold can certainly hurt you. But mold isn’t always harmful. Still, we don’t recommend consuming foods with visible mold growing on them as some molds can produce mycotoxins which can make you very sick.

What Does Bad Sour Cream Smell Like?

Sour cream naturally has a tangy odor. However, if that smell is stronger than usual or seems particularly rotten, chances are that the sour cream has gone bad.

Is Sour Cream Still Good If It’s Watery?

That depends. Sour cream that has water or liquid on top isn’t odd. In fact, it can be perfectly normal. That’s because the water that presents itself on both sour cream and yogurt is known as whey. It’s naturally occurring and is perfectly safe. Try mixing to see if it can achieve the same creamy consistency we’re all familiar with.
If, however, there are other signs of spoilage such as a bad smell, bad taste, mold, or discoloration, your best bet is to opt for new sour cream.

Is Lumpy Sour Cream Bad?

There are a few reasons why your sour cream may get so lumpy it can resemble cottage cheese. Maybe the sour cream was frozen at a point in time. Or the sour cream was heated. Or perhaps the sour cream has gone bad. To know whether or not the lumpy sour cream has gone bad, smell it, taste it and check the expiration. Maybe even mix it together to see if it will re-incorporate. If you’ve left sour cream sitting out and you notice that it now looks like cottage cheese, be sure to throw it out.

What Happens if You Eat Expired Cream?

If you eat expired dairy, you will always run the risk of food poisoning and unpleasant digestive issues.

  1. The container says July 18, 2022, but it looks and smells fine! Didn’t taste it though. Today’s date is November 16, 2022. Again, it looks perfectly white and smells normal. BUT, I guess I still need to toss it 😕 Why doesn’t it look or smell off. Plus, it has been opened and just sitting in the back of the fridge.
