This is one of those easy rhubarb recipes that you’ll be so glad is in your back pocket and one you’ll likely repeat year after year for its versatility.

Let’s face it there’s only so much rhubarb pie a person can eat, saving some for later feels like a prudent thing. This recipe will put an end to all that wondering about what to do with rhubarb every spring season.

Is Rhubarb a fruit or vegetable?

Rhubarb is technically a vegetable. However it is a vegetable that we eat like a fruit and a high acid vegetable, at that, making it safe for water bath canning.

It’s also a vegetable that we treat like a fruit in that we most often combine it with other fruits and use like a fruit in most recipes.

An Easy Preserve

Stewed rhubarb is simply sliced rhubarb mixed with sugar and gently boiled.

That mixture of sugar, rhubarb, and juice is then put into jars and canned.

It doesn’t get much easier, no making of sugar syrup, no need to worry about gel stage, etc.

It’s also easy to double or triple, if desired. Make lots to give away to friends and family who will appreciate it come winter.

How to Prepare Rhubarb

Once the rhubarb is pulled from the plant, remove the leaves. The leaves are poisonous and should not be eaten.

Then simply wash the stalks. A rinse under cool water is generally enough to remove any surface dirt. Some stems might need a light scrub with a brush to remove any stubborn bits of dirt or mud.

After the wash simply shake off any moisture and proceed with the recipe.

How to Cut Rhubarb

You will have most success with a very sharp knife. Rhubarb can be kind of stringy, this isn’t a problem at all but you can reduce the instances of those stringy bits essentially peeling your stalks by making sure to use a sharp knife.

Place the rhubarb onto your cutting board with the flatter edge down. Cut the rhubarb into one inch pieces for this recipe by simply slicing with your sharp knife. Make quick work of it by lining up two or three stalks to cut through at once.

Ways to Use Stewed Rhubarb

These beautiful jars are a simple addition to many meals in winter:

  • Use as a pancake / waffle topping instead of syrups
  • Mix in with oatmeal and other hot cereals for a flavorful, fruity punch
  • Top ice cream, poundcake, or sweet shortcake biscuits for an easy dessert
  • Dumplings! Put a jar or two into a pot and heat, add dumpling batter and cook until the dumplings are cooked and fluffy.
  • Stir into homemade yogurt
  • Pour a jar or two into the bottom of a pie plate and top with oats and melted butter for a crisp-style dessert.
Yield: 7 Half Pints

  2. While the fruit stands, get the boiling water canner going and get jars, lids, and rings ready.
  3. Once some water has started to release from the rhubarb, bring it to a gentle boil, stirring to prevent scorching. Ladle the stewed rhubarb into hot jars leaving 1/2" headspace. Clean rims, put on lids and rings.

There's some advice for pressure canning rhubarb here but I've never tried it:

I do this same thing, only I add a little vanilla to mine. Makes it even better in my opinion.

Love this recipe! So easy! I did not have enough half pints so used one pint and that one turned out fine.

Could you use this as a pie filling? What would you need to add?

@Carole Leone, you can definitely make pie filling! For rhubarb, get some Instant ClearJel (not to be confused with SureJel). For every 8 cups of rhubarb add 6 Tbsp+2 tsp. Follow directions on package. You can also use Pie Filling Enhancer, for every 8 cups of rhubarb use 1 cup enhancer but you must reduce you sugar by 1/2 cup, since the enhancer has sugar in it. Hope this helps.

Probably though I haven't tried it yet. You'd want something to help it set, some eggs & flour maybe. I have an apple butter pie recipe here: - I imagine the stewed rhubarb could work as a substitute for apple butter but I can't promise. I keep wanting to try a stewed rhubarb pie but never seem to get around to it.

What do you think about a little beet juice for coloring. When I cook beets there's that beautiful purple juice..maybe a good sub for food colors.?

My concern about adding beet juice is that it will lower the acidity level which isn't good for canning.
