Do Marshmallows Expire?
Marshmallows eventually do expire, but not in a way other foods do. After the expiration date, they usually remain good for approximately one month or two if remain unopened. Once opened, the sugar candies retains quality for about 1 week.
Marshmallows can be eaten about a month after the expiration date, or expiration date if the marshmallow has not been opened. If the container has not been opened, marshmallows can be consumed within a few weeks after the expiration date. Once the package is opened, marshmallows can last anywhere from 7 days to 4 months, depending on how you store them. Marshmallows usually stay fresh for 1-6 months past the expiration date printed on the package if the package has never been opened.
| Types | Past Expiration Date | Fridge | Freezer | Pantry |
| Open Marshmallow | 1-2 months | 3 days | 3 months | 1 week |
| Packaged Marshmallow | 6-8 months | 1-2 week | 4 months | 2 months |
Marshmallows usually keep for a few weeks after a date and one to two months after the package is first opened. Unopened, they can stay fresh even months after the expiration date.
Sure, marshmallows can keep good quality for a few more months or even longer, but who knows for sure. While marshmallows may be safe to eat after opening for a month, they probably won’t taste as good as they used to. When it comes to homemade marshmallows, they probably won’t keep for long.
If you buy marshmallows online, you can be sure that they will last longer than anything else you buy in the store. Marshmallows, like in the pantry or refrigerator, will last longer in the refrigerator. Marshmallows stored this way can keep for up to three months if not reopened after refrigeration. If for some reason one month’s storage isn’t enough for you, you can freeze marshmallows.
For more time, you can refrigerate the marshmallow after opening or even freeze it. Store the container in the refrigerator to store the marshmallows for 1 week, or the freezer for up to 4 months. Unopened marshmallows will keep for 1 month in the pantry, up to 2 weeks in the refrigerator, and up to 4 months in the refrigerator.

As for marshmallows, an unopened package of marshmallows will keep for about a month or more (sometimes 4-8 months) when stored in a cool, dry, dark place away from direct sunlight and heat. Marshmallows have a shelf life of 1-2 weeks when stored in an airtight container or zippered plastic bag in a cool, dry, dark corner of the storage room away from direct sunlight and heat. If you follow the right steps and store a bag of high-quality marshmallows in an airtight jar, it will last for weeks.
Close the opened package well and place in the freezer if you will not use the marshmallow for a long time. If your bag of marshmallows is nearing its expiration date, you can zip it up and put it straight into the freezer. Once you open the marshmallow bag, make sure you seal it very tightly or even place it in a zippered bag that you can bleed the air out of.

If your marshmallows are old, stale, and hard, you can simply place it in a resealable plastic bag with a slice of bread to soften the aged marshmallows again. All you have to do is take a slice or two of wet bread and put them in a resealable plastic bag along with the marshmallows. You can add some moisture to stale marshmallows by adding a slice or two of bread to the bag. This loaf will absorb excess moisture from the marshmallow bag or container, keeping the marshmallows fresh for a while.
Use a spoonful of cornstarch to keep marshmallows from sticking together after long periods of storage in an airtight container. Even better, it takes about 10-30 minutes to thaw them on the counter, or you can put them in a hot drink and they’ll be ready right away.
