All One Needs to Know About Freezing Rhubarb

Rhubarb, even being a vegetable, must normally be prepared as a fruit. 

Many people wonder which part of it is edible, the stalks or the root crop. In terms of consuming, only the stalks are possible to eat since the leaves are toxic, the same as the root crop. 

Regarding this, the question occurs about the rhubarb freezing. Since the stalks remind celery and contain much water, is it possible to expose them to frost? Will they not get freezer-burnt because of the long exposure of the low temperature? 

How to Freeze Rhubarb

Well, a way exists how to freeze rhubarb raw and avoid its ruination, as well as the loss of the qualities.

  • Firstly, it is essential to figure out how to prepare rhubarb for freezing.

Since the stems are growing over the soil, they are always being exposed to the impact of external factors like dust and dirt. In addition, some harmful bacteria may get onto them.

So wash them in advance before using and dry thoroughly.

Choose only the vegetables with the fresh-looking, crisp and blemishless stems!

  • To make sure that the only edible part of the vegetable is safe to consume, start with removing all the leaves since they are poisonous and can’t be eaten by no means!
  • Peel rhubarb stems to delete the tough outside fibers.
  • Cut them in pieces, approximately two and a half centimeters each.
  • Now it is time to decide whether rhubarb will be preserved for a long period of time or not. In case it is going to stay frozen for more than three months, it would be more reasonable to blanch it before freezing since it is the best way to freeze rhubarb.

If not, then preserving rhubarb raw is also fine.

Drain and instantly remove rhubarb to the ice-cold water to stop the process of cooking and fix the color.

Drain once again and spread evenly on paper for drying.

  • Now decide which way to use it. If all the vegetable will be used at once, it would be better to freeze it all together in a single frost-friendly tank. 

But if you’d prefer to take some once in a while, then open-freeze it on a baking sheet for a couple of hours and then toss into a frost-proof tank or packet.


After being preserved like this, fresh rhubarb will keep its taste and color together with the crispness. In addition, such a  method to preserve rhubarb allows it to remain edible for nine months at most!

Of course, someone would prefer to leave rhubarb stalks as they are, raw and unblanched, and expose them to frost in this condition. 

Feel free to do as you wish but remember that, when being frozen raw and unblanched, rhubarb stalks will manage to last for nearly three months or so.

In addition, blanching preserves its major qualities such as taste, crispy texture, and flavor for much longer.

Anyway,  preserving it raw is also fine. To freeze rhubarb, just wash the stems and peel as you would do for blanching first. Then cut them and put the pieces into the frost-resistant tank.

Of course, rhubarb is possible to keep unfrozen as well. However, this way of rhubarb storage is good only if you are sure that it will be used pretty soon and won’t start getting spoiled.

When storing rhubarb, keep into account that this vegetable is quite watery which means that it can easily be exposed to spoiling because of improper storage conditions.

So, to extend its shelf life, cut off all the leaves leaving the stalks completely bold.

Then wrap them into the ordinary plastic wrap and refrigerate. Like this, the lifespan of the vegetable will be extended for one week.

Never wash rhubarb before refrigerating because it may cause the sooner rotting!
