Expiration & Storage Tips
When does celeriac expire?
Unopened and kept at cool storage and high humidity like a root cellar or second fridge, celeriac can last for 3-4 months. If you don't have such a storage option, the vegetable will stay fresh for a solid 2-3 weeks in your kitchen's refrigerator. Once the celeriac has been peeled or cut, you should store it in an airtight container and it will last for about a week in the refrigerator. If frozen, celeriac can last up to a year, but be aware that freezing may change its texture upon thawing.
How do you tell if celeriac is bad?
Check the condition of the skin and the feel of the celeriac. If the celery root has become slimy, soft, or it's starting to mold, it's time to let it go. A bad smell can also be an indicator that the celeriac has gone bad. And of course, if you see an unusual amount of dark spots, it's probably best to toss it away.
Tips for storing celeriac to extend shelf life
• Keep your celeriac in a cool, dark place with high humidity to maintain its quality.
• If cut or peeled, store the celeriac in an airtight container in the refrigerator to slow its aging process.
• If you're planning to freeze celeriac, blanch it first and then store in a tightly sealed freezer bag.
• When freezing, in order to maintain taste and texture, try to use frozen celeriac in cooked applications, like purees, soups, or stews.
