How To Prepare Chestnuts For Freezing
Before you freeze chestnuts, you need to prepare them. Although you can throw unprepared chestnuts in the freezer in their shells, there’s simply no point. Instead, do the prep work first so that you have ready to enjoy chestnuts in the freezer.
To get them prepared for the freezer, follow these simple instructions:
- Select and Wash
Pick healthy, mature chestnuts. These have a shine, are firm to the touch, and do not bend or crack when pressed then wash your chestnuts.
Score the chestnut skins on one side – making sure not to pierce the nut below. This can be done carefully with a knife or scissors. Give your chestnuts a gentle squeeze to ensure you have broken the skin.
- Soak then Boil
Soak the scored chestnuts in filtered water for 2 hours. After 2 hours, transfer chestnuts to boiling water and boil for 2 minutes. Meanwhile, have a dry saucepan heating.
- Dry Then Toast
Transfer boiled chestnuts to a dry towel and pat dry. Transfer chestnuts to the warm saucepan and cover with a lid for 30-60 seconds This will cause the chestnuts to open on their own.
Transfer opened chestnuts to a towel and peel while hot, be sure to wear heat resistant gloves to protect your hands from burns.
How to Freeze Peeled Chestnuts

Once frozen, store chestnuts in a freezer-safe bag or container.
- Label and Freeze

3 Tips for Freezing Chestnuts
Now you know how to freeze them, we’ve got our 3 top tips which we strongly recommend following when freezing chestnuts to have the best results:
Freeze Them Peeled
Freezing any food is all about saving time. Freezing them peeled means all the fiddly prep work is done for you so when you want to enjoy chestnuts, you can.
Chestnuts toasted over an open fire is the epitome of Christmas. But if you want to toast them then do so after removing them from the freezer. If you roast them beforehand you’ll find the flavour degrades faster.
Cook from Frozen
If you’re making stuffing, filling or paste from your chestnuts then you don’t need to defrost them. You can grab them from the freezer and straight into the pan.
How Long Can You Freeze Chestnuts?
When freezing chestnuts it is always recommended to use air-tight bags or containers. A vacuum-sealed bag will not only last longer but help retain original flavours when freezing.
The best part about chestnuts is that they can be frozen raw or cooked and last from 6-9 months.
As always when freezing any fresh foods, be sure to clearly label each container with what is in the package, along with the date it was frozen.
You Can Freeze Chestnuts for up 9 Months
How Do You Defrost Chestnuts?
Once you’re ready to cook with your chestnuts, it’s time to take them out of the freezer. Much like other fruits and nuts, you can cook with your peeled frozen chestnuts right away to make some delicious meals.
If you prefer to defrost them first, you can either do so at room temperature or in the fridge.
For chestnuts that are in the shell, it’s best to let them defrost at room temperature for several hours. This will prevent them from retaining moisture and becoming mushy. Once fully defrosted, you can cook with your in-shell chestnuts as normal.
Can You Refreeze Chestnuts?
Refreezing chestnuts is not something we would recommend. It will ruin the texture and flavour drastically even if it is likely to be safe to eat them.
The only exception to this advice is if you have frozen chestnuts then made stuffing or filling from them that you then want to freeze. You’ll be fine to freeze it in this way even if they have previously been frozen.
Do Chestnuts Freeze Well?
Nothing beats freshly harvested Chestnuts.
That being said, chestnuts do freeze really well and will maintain much of their original flavour. There is a slight difference in texture, which is to be expected after freezing. Following the defrosting instructions will help preserve your chestnuts texture and flavour as they become sweeter as they dry.
If you’ve still got questions about freezing chestnuts or chestnuts in general, then these may help:
Can You Freeze Chestnut Stuffing?
You can freeze chestnut stuffing. You just need to make it as you normally would before storing it in a freezer bag.
Before placing the bag in the freezer, do your best to remove as much air from the bag as possible before placing it in the freezer. Make sure you defrost it fully in the fridge overnight before cooking.
Can You Freeze Roasted Chestnuts?
Freezing roasted chestnuts is doable but not advised. Freezing can ruin the nutty texture and flavour so we would advise against it. Instead, freeze them as above and then roast them at a later date and enjoy them warm.
