Using Freeze Dried Rhubarb

Joy! Rhubarb is in season. This week I bought a bunch in the grocery store just in time for a Memorial Day pie. I had to explain to the cashier what it was, and she still kept calling it “Roobark”. This exchange made me worry that my favorite vegetable was being overlooked by the next generation. Do people even eat rhubarb anymore?

I had barely finished eating my pie when we got an email from the owner of a Harvest Right freeze dryer. I was so pleased to know there were other rhubarb devotees out there. (Thanks Debra M. from Rexburg, Idaho!)

Debra says her neighborhood has an email group and someone sent a note offering free rhubarb. Nobody claimed the rhubarb so Debra picked up a large sack and toted it home to meet the freeze dryer. On more than one occasion I have picked up construction size garbage bags full from my own neighbors!

Debra says that one freeze dryer batch of rhubarb makes about 7 quarts and she vacuum packed it into 2-quart jars. The first recipe she tried was rhubarb bread. Recipe below:

Rhubarb Bread

Crunchy top with a sweet and nutty inside.


Mix together:

  • 1/3 cup sugar
  • 1 tablespoon soft butter


Mix together:

  • 1 ½ cup brown sugar
  • 2/3 cup oil
  • 1 egg
  • 1 cup buttermilk
  • 1 teaspoon vanilla

Mix together:

  • 2 ½  cups flour
  • 1 teaspoon salt
  • 1 teaspoon soda
  1.  To the dry ingredients fold in 2 cups of freeze dried rhubarb that have been rehydrated and drained. Fold in 1 ½ cups nuts.
  2. Combine wet and dry ingredients and stir until incorporated together.
  3. Pour into 3 small loaf pans of two medium size loaf pans that have been greased and floured.
  4. Crumble the topping on the top of each loaf
  5. Bake at 350 degrees for 40 to 45 minutes.

NOTE: To rehydrate the rhubarb, cover the dry rhubarb with water and let it absorb the water for about 5 minutes. I placed a regular size canning lid in a wide mouth mason jar on top of the water and rhubarb to submerge the floating pieces of rhubarb to help with the rehydrating process.  Drain well.

thank you for this post. we just got our freeze dryer and plan to freeze dry much of our huge rhubarb patch. very excited to free up our freeze space by having shelf stable supply of rhubarb

We love rhubarb, especially my husband, so after we got our HarvestRight, I f-d’d some rhubarb. I will be trying the rhubarb bread above since up to now my use of the f-d’d rhubarb in pies or crisps has been VERY unsatisfactory. The f-d’d rhubarb seems tough, gummy, and void of the usual rhubarb tartness. I am open to any and all tips that might cure this problem so I don’t have to go back to freezing my rhubarb.

I blanched my rhubarb peices for 1 min. Let them air dry over night. put on cookie sheets & froze them for 2 days. Then i put them in the freeze dryer. The flavour & color was locked in. Quite delicous

I have freeze dried my rhubarb. It’s so handy and the flavor stays so amazing. We are a big rhubarb family!

Just freeze dried a batch using two treatments. One was raw rhubarb and the other batch I had soaked the cut rhubarb overnight in simple syrup. The raw was light and fluffy and tasted ok I really liked the soaked rhubarb. It was a great snack
