For those who wish to preserve this strawberry rhubarb butter long-term, try your hand at canning rhubarb butter.
Ingredients
Rhubarb is available before strawberries are. Gather and freeze the rhubarb until the garden strawberries have ripen.
- 2 pounds fresh rhubarb stalk, cut into 1-inch pieces
- 2 pounds fresh strawberries, remove the green tops and cut berries in half
- granulated sugar, 1 cup
- light brown sugar, 1 cup
- vanilla extract, 1 tablespoon
Equipment
Preparing this recipe over the stove is doable. Simply set the over burner to low and allow the ingredients to simmer for 45 minutes(ish). Take note to use non-reactive pots such as stainless steel, enamel dutch oven, or a copper jam pot.
Because we are busy, the use of an electric slow cooker is practical and much more convenient.
- 8-quart slow cooker
- silicon spatula
- steam canner, or hot water bath canner
- immersion blender (stick blender)
- jar funnel
- air bubble remover
- 1/2-pint mason jars, or pint-size jars
Slow Cooking Instructions
This is a prepare and walk away recipe. Go about tending to the family, garden, or livestock and allow the ingredients to transform themselves into a delicious and easy rhubarb strawberry butter.
- Add all the ingredients to the slow cooker, gently folding the ingredients until thoroughly mixed.
- Place lid onto the slow cooker at an angle, do not latch the lid.
- Place the setting to cook on low, set timer for 4 hours.
- Stir the mixture often to ensure the sugars are mixed with the strawberries and rhubarb.
- Once the rhubarb has completely softened, the strawberry rhubarb butter is done.
- Using an immersion blender, slowly blend the rhubarb butter, taking care to not over blend. If the butter appears to be watery, slow cook the butter on high with the lid off until the desired consistency has been met.
Canning Instructions
Processed the pint jars using either a steam or hot water bath canner.
A steam canner is a much more efficient tool which uses 2 inches of water and processes jars with steam. Unlike the steam canner the hot water bath canner processes jars using boiling water.
- Prepare jars, lids, and canner.
- Using jar funnel, ladle this easy strawberry rhubarb butter into new or sterilized mason jars. Make sure to leave a 1/4 headspace.
- Remove any air bubbles using the air bubble remover. Add additional strawberry rhubarb butter as needed.
- With a clean dishtowel, wipe the rims of the jars. Add warmed lids and rings finger tight.
- Process the strawberry rhubarb butter in a steam or hot water bath canner based on your altitude, see notes below.
Notes
- Please note, since the fruit butter was made in a slow cooker it is necessary to bring it raging hard boil prior to canning. Jams and jellies must boil at 212 degrees Fahrenheit for a minimum of 2 minutes prior to canning to kill any potential bacteria within the food.
- *Canning time for this easy strawberry rhubarb butter recipe – 1/2-pints or pints see below.
- Additional strawberries can be added to minimize the tartness of the rhubarb.
- To substitute honey for the sugars, begin with 1 cup of honey and increase the amount as desired. Keep in mind, honey will alter the original flavor, it is best to increase the amount of honey slowly.
- An 8-quart slow cooker yields roughly 8 1/2-pins or 4 pints.
Processing Time
- Below 6,000 feet elevation – process 10 minutes
- Above 6,000 feet – process 15 minutes

As you can see, rhubarb is a prized garden item in many households. In addition to the methods mentioned here, this tart stalk freezes quite well, too. The means for enjoying rhubarb year-round is great. Do not let the opportunity of making it shelf stable slip through your fingers!
Thanks, been waiting for this!
Thank you for this post. My rhubarb is ready and I am so busy. Off to the store to buy the berries. Love your site
Thanks for the recipe! After several years I finally got rhubarb to grow in Oklahoma. No strawberries this year though. Will this recipe be ok with just rhubarb? I really try to only use what I grow.
Thanks!
Michelle
Rhubarb is tart, but the sugars sweeten it. The strawberries only balance it out more. If you are looking for items to add to the rhubarb, pineapple works great too!
There is a recipe for rhubarb sauce over at the Old Farmer’s Almanac that you might want to try. It’s made with all rhubarb (sugar and water are the only other ingredients).
That is how I put up rhubarb simple syrup. It’s amazing over just about everything!
I have frozen rhubarb that I put away earlier this spring. Will that work? Do I let it thaw or put it in frozen?
It will work great, and yes thawing it would be best.
Can you freeze the strawberry rhubarb butter after you make it? Also, do you need to use pectin? I don’t see it listed.
Thanks!
Hi there, it can be frozen instead of canned. Because it is a butter and not a jam or jelly, pectin is not needed. It is meant to spread like butter.
In your notes you indicate that when prepared in a slow cooker, it is necessary to bring to a raging hard boil prior to canning., and that jams and jellies must boil for 2 HOURS prior to canning. However, in the recipe you bring it to a raging hard boil for up to 2 MINUTES. Should it be cooked for 2 hours or 2 minutes? Thank you.
I apologize! In the note section of the recipe card it should have read, bring to a hard boil for 2 minutes, not 2 hours. I have adjusted the recipe card.
