How Long Can You Freeze Rhubarb? 

You can freeze rhubarb for up to a year. Especially if it has been blanched, it will stay vibrant and flavorful for a long while.

But as in the case of any fruit or vegetable, the quality of the rhubarb will deteriorate, the longer it stays in the freezer, so it is best to use it up sooner rather than later. 

If you are freezing food made with rhubarb, they would last well in the freezer for a couple of months before they lose their taste and texture.

How to Store Frozen Rhubarb? 

You can store frozen rhubarb in any freezer-safe air-tight container or Ziploc bag. The key is to freeze it completely sealed and protected from being exposed to air or freezer burns. 

If you are pressed for freezer space, then the best option would be Ziploc bags.

While the freezer-safe containers can be bulky and limit the quantity of rhubarb you can freeze, the Ziploc bags are a great way to freeze even large batches compactly. 

How to Defrost Rhubarb? 

If you want to defrost the frozen rhubarb, take out the portion you need and leave it in the fridge for a couple of hours or overnight, and let it thaw gradually. 

But in most cases, you needn’t bother thawing the rhubarb. You can use them right out of the oven and cook or bake with them.

Keep in mind that the rhubarb can get mushy or soggy once it thaws. So, it is best to use them in recipes where you cook them and don’t call for thawing it first.

Can You Refreeze Rhubarb? 

Although you can refreeze rhubarb, it is best advised not to. The rhubarb can change in texture and get mushy once it thaws.

Repeated freezing and thawing will only worsen this condition. So, it is best not to refreeze rhubarb and also risk the chance of bacterial buildup.

To avoid having to refreeze or waste the rhubarb once it thaws, you can freeze them after portioning it into quantities you can easily consume in one go.

You could also flash freeze the pieces of rhubarb beforehand to easily grab a handful without thawing the whole batch.

Does Rhubarb Freeze Well? 

Yes, rhubarb freezes well, and it is a great way to have the delicious fruit at the ready all year long. If it has been blanched beforehand it freezes much better and for longer.

Dishes cooked with rhubarb, like rhubarb crumble, also freeze quite well. 

But keep in mind that while rhubarb freezes well, it isn’t too appealing once it thaws. So, frozen rhubarb is best used right out of the freezer and when cooked. 

FAQs

Can you freeze rhubarb without blanching? 

Yes, you can freeze rhubarb without blanching. You can directly pack and freeze it or flash freeze it first and then freeze it for the long term. But to keep the flavor and color of the rhubarb intact it is best recommended to blanch it first.

Can you freeze rhubarb compote? 

Yes, you can freeze rhubarb compote. Once it is cooked and cooled, you can portion and freeze it in Ziploc bags or freezer-safe air-tight containers. You could also pour them into an ice cube tray and flash freeze them into small cubes before freezing them for the long term.
