A recap of how to store and prepare chestnuts in the fridge and freezer
When autumn comes, I always want to buy chestnuts, but when I get too many at once they are hard to finish. Delish Kitchen published an article that summarises how to store and prepare chestnuts in the fridge and freezer, so I want to note the key points. It was reviewed by a registered dietitian and dated 6 October 2026.
The basic idea is simple: refrigerate if you will use them within a few days, and freeze if you cannot finish them soon. Either way, before storing, remove any chestnuts with holes and wipe off the surface moisture thoroughly. Chestnuts with holes or small spots on the shell may have insects inside, and ones that float when placed in water may also have gone bad, so avoid them.
The refrigerator method has three steps. First, check for holes. Second, boil plenty of water in a pot, add the chestnuts, turn off the heat, and leave them for one minute before draining. Third, leave them on kitchen paper until they cool and the moisture evaporates, then wipe off any remaining water, wrap them in newspaper, and put them in the fridge. The article does not give a specific number of days for refrigerated storage. It only says to use them as soon as possible.
For freezing, peel off both the outer shell and the inner skin first. If freezing raw, soak the peeled chestnuts in water for about 5 minutes, drain, dry them, lay them flat in a freezer bag, and press out the air. If freezing after boiling, simmer them over medium heat for about an hour in enough water to cover them, then cool and peel them and pack them the same way. The article warns that boiled chestnuts must be reheated before eating, and it suggests about one month as a guide for storage time. For long-term storage, it also introduces coating them with sugar or salt to prevent freezer burn.
As a bonus tip, freezing chestnuts in their shells and then dipping them in hot water softens the outer shell and makes the inner skin easier to remove. Peeled chestnuts should be soaked in water right away to remove their bitterness. Peeling has always felt like the hardest part, so I want to remember this tip.
