If you grow rhubarb then you’ll want to know how to preserve it so you can use it all year long. Freezing it is a great way to preserve it.

What is rhubarb?

Rhubarb is a perennial plant that grows from rhizomes. The stalks of rhubarb are edible and are often red or green. Rhubarb stalks resemble celery in looks but taste entirely different. They have a very sour taste. The leaves contain high levels of oxalic acid and are inedible. 

How do I harvest rhubarb?

I select a few stalks from each rhubarb plant to remove. I never take more than 1/4 of the plant at a time. You want your plant to continue producing and taking too many stalks may cause it to die.

How do I use frozen rhubarb?

I use frozen rhubarb in any recipe calling for rhubarb. Many times I will add it frozen and increase the cooking time by 5-10 minutes. You can use frozen rhubarb in rhubarb muffins, rhubarb bread, rhubarb sauce and this delicious rhubarb crisp.  It can also be used in a savory BBQ dish from House of Nash Eats. 

Tips for freezing rhubarb

  • Always label your freezer bag and add the date. 
  • Cut rhubarb to the size you will need for a recipe.
  • Freeze in a freezer that does not have an automatic defrost.
  • Use rhubarb within one year.
  • If rhubarb freezes together, just gently break apart while still in bag.
  • Freeze the amount you have on hand. Sometimes I have just a few cups to freeze and other times I may have several dozen cups.

    This is such a great idea. Everyone I know who loves rhubarb awaits it’s relatively short season with such anticipation. I love how pretty it looks with that bit of frost in your first photo, too. ๐Ÿ™‚ ~Valentina

    Several dozen cups!? Holy cow, Kathy! I’m jealous of your freezer! At any given time, you must have the most amazing selection of frozen berries, rhubarb, fish, etc. The timing on this post is perfect as rhubarb season is wrapping up. We didn’t do much of a garden this year with the new house (just a couple tomato plants in pots), but perhaps we’ll plant some rhubarb next year! You’ve inspired me!

      It gets a little crazy. We have three large deep freezers. Two are in our basement and one in the shop. It’s great for storing things but it’s also easy to forget what’s in there!

    Though I was only able to harvest our rhubarb only once so far this season, I know I’ll refer back to this later on because we usually end up with lots! Freezing is such a great idea so I can enjoy rhubarb all year long! Thanks for this Kathy ๐Ÿ™‚
