In this post, I’ll share not only how dehydrate rhubarb, but more importantly why you would want to and how to use it.
How to Dehydrate Rhubarb
Here’s how to dehydrate rhubarb in six easy steps using a dehydrator. I use an Excalibur 9 tray model.
- Pick and wash rhubarb stalks. Choose fresh, good quality rhubarb stalks that aren’t woody.
- Chop rhubarb into even, 1/4 to 1/2 inch pieces (1 to 2 cm).
- Spread in a single layer on mesh dehydrator trays.
- Dry at 135°F (57°C) for 8 to 12 hours depending on your dehydrator, rhubarb and humidity levels.
- Rhubarb will feel dry and crisp with no moisture inside when broken open. Err on the side of over-drying if in doubt.
- Turn dehydrator off and let rhubarb sit overnight before storing in a well sealed container in a dark, dry space for up to 1 year. Dried rhubarb will be safe to eat beyond one year, but the color will change over time. To preserve color for longer, blanch rhubarb for 2 minutes before drying.
Why Dehydrate Rhubarb?
I dehydrate rhubarb because it’s an easy, economical and convenient way to preserve and store rhubarb. In its dried form, rhubarb takes up hardly any space and will last 6-12 months before its color begins to deteriorate.
Unlike other fruit, I don’t dehydrate rhubarb as snack food. While some people may enjoy chewing on these tart nuggets, I prefer to use my dried rhubarb in various recipes, not to eat as is.
How to Use Dried Rhubarb?
Dehydrated rhubarb can never be turned back into juicy, fresh rhubarb. It will plump up when soaked in water, but it will have a slightly chewy texture. So use dried rhubarb in recipes where a little added texture is appreciated, e.g. muffins, oatmeal, pancakes, cookies, etc. The longer it cooks or stews in liquid, the less chewy it becomes, so you could also use it in sauces – rhubarb sauce on pork chops perhaps?
My favorite way of using dried rhubarb is in homemade tea blends like this apple and rhubarb mix, one of the 40+ recipes in the Rhubarb eCookbook.
Or in these honey rhubarb bran muffins, also found in the Rhubarb eCookbook.
How to Rehydrate Dried Rhubarb
It’s hard to give specific amounts of how much dried rhubarb to use in any recipe because each batch is different and will rehydrated differently. For that reason, I prefer to rehydrate rhubarb before adding to recipes (except when making tea blends). This allows me to see how well the rhubarb plumps up and how much I need in a particular recipe.
To rehydrate, pour dried rhubarb in a bowl and add twice as much boiling water. Allow to rest for 60 minutes. Drain water and use in recipes as you would fresh or frozen rhubarb.

Can you use dehydrated rhubarb for pies
I haven’t tried it, but you should be able to. Just re-hydrate the rhubarb in warm water until it’s plumped back up. It won’t return 100%, but it should work. Let us know how it goes.
Do I need to boil my rhubarb if it is frozen first?
Hi Dawn,
If you’re planning to dehydrate your frozen rhubarb then no, you do not need to boil it first. Just thaw it and drain it very well. Your dried rhubarb will look more like little shredded bits rather than solid pieces, but depending on how you’re using them, that shouldn’t be an issue.
All the best,
