How Long Does Heavy Cream Last?
The good news is that heavy cream has a pretty long shelf life! When unopened, it can stay fresh for up to a month if you keep it stored in the refrigerator below 40°F (4°C). The best part is that you can still use heavy whipping cream 5 days past its expiration date.

Once opened, heavy cream can still last up to 1 month, but it pretty much depends on the storing conditions. The high-fat content (36% to 48%) of heavy cream helps slow down spoilage, given that it’s kept at a constant, cold temperature. Factors that affect its lifespan include whether the cream is pasteurized or ultra-pasteurized, temperature fluctuations, and how well it’s sealed.
If it’s ultra-pasteurized, it might even last longer due to the heat treatment that kills bacteria. Just remember that leaving it out on the counter will shorten its lifespan drastically!
Tips For Storing Heavy Cream
Proper storage is key to extending the shelf life of heavy cream. Whether opened or unopened, it should always be stored in the refrigerator at 40°F or lower. The best spot is at the back of the fridge, where the temperature remains most consistent, instead of the door where temperatures fluctuate more frequently.
Keep heavy cream in its original container if it seals well. Otherwise, transfer it to a sterile, airtight container to prevent exposure to air and contaminants. Never leave heavy cream at room temperature for extended periods. Two hours is the maximum amount of time it should sit out, and even less if temperatures are higher.
Unopened heavy cream can be used for several weeks past the expiration date if it remains unopened and shows no signs of spoilage. However, for the best quality, try to use it before the date on the package.
What about freezing? You can stash it in the freezer for up to 3–4 months, but doing so may affect its texture, making it grainy or separate once thawed. Here’s my secret: I scoop the heavy cream into ice cube trays and transfer them to a freezer-safe container once solid. When the mood strikes, you only have to defrost enough ice cubes for your recipe.
Before using, thaw it overnight in the fridge and stir well.
How To Tell If Heavy Whipping Cream Is Bad?

Pay close attention to these red flags:
- Sour smell: One of the clearest signs that heavy cream has gone bad is a sour, unpleasant odor. Fresh cream has a neutral or slightly sweet smell, so any off odor indicates spoilage.
- Discoloration or mold: Check the surface of the cream and the container for mold or any discoloration. Heavy cream should be white or slightly off-white. Any green, blue, or other odd colors signal contamination and spoilage.
- Separation of liquids and solids: If the cream has visibly separated into liquid and solid components and it doesn’t re-mix smoothly, it’s likely spoiled. Some slight separation is natural, but large amounts of liquid separating from the cream are a red flag.
- Thickening or lumps: Spoiled cream may have an oddly thickened or lumpy texture, resembling cottage cheese. If your cream has these curdled clumps, it’s no longer safe to use.
- Bubbles: The presence of bubbles in heavy cream may indicate bacterial activity. Bubbles are a sign that spoilage has begun, and the cream should be discarded.
- Sour taste: If you’re unsure and taste a small amount, spoiled heavy cream will have a sour or off flavor. Unlike sour cream, this sourness is a sign of spoilage and should not be consumed.
Ways To Use Up Heavy Cream
If you have leftover heavy cream, there are plenty of delicious ways to make use of it before it spoils. One of the most popular uses is making whipped cream. With just some vanilla and sugar, you can create a perfect topping for desserts like cakes and pies

Or why not make homemade butter? It’s a simple process of whipping the cream until the butterfat separates, leaving you with fresh butter and buttermilk. I also found that heavy cream made no-churn ice cream or frozen desserts like gelato or sorbet. It adds creaminess and texture to these frozen treats.
This dairy product is also the star in many baking recipes, such as scones, biscuits, and cakes, infusing moisture and tenderness into doughs and batters. Besides, I love transforming heavy cream into sour cream or even cream cheese with just several drops of cultures or lemon juice. These dairy staples are easy to make and great for dips, spreads, or baking.
Additionally, it is excellent for making cream-based soups or thickening sauces like alfredo or creamy tomato sauce. Tossing it into soups or pasta dishes enhances richness and flavor.
FAQs
What To Do If Heavy Cream Turns Sour?
If heavy cream turns sour, it is best to discard it. Sourness indicates spoilage and the presence of harmful bacteria. Using sour heavy cream can affect the taste and safety of your recipes, so it’s safer to throw it away.
Can I Use Heavy Cream After The Expiration Date?
Yes, unopened heavy cream can still be used for several weeks past its expiration date if it’s been stored properly in the refrigerator. However, once opened, heavy cream should be consumed within 5 days after expiration, and always check for signs of spoilage before use.
