Rhubarb Sauce with Strawberry Jello is a favorite old-fashioned rhubarb treat. Serve it over ice cream or eat it in a bowl just like you would applesauce.

Rhubarb Sauce with Strawberry Jello

Old fashioned rhubarb sauce is sweet, tangy, and perfect as a snack or dessert.

This was originally one of my great grandma’s rhubarb recipes and true to her style, her original recipe read like this:

“Add just enough water so rhubarb doesn’t stick while cooking. Add sugar to taste and jello to thicken.”

She didn’t list an amount for the ingredients, just basic instructions. 

Thankfully after some trial and error, I’ve nailed down amounts for each of the ingredients and more specific cooking instructions.

At family gatherings, we’ve always served this sauce as a side dish, just like applesauce. That is still my favorite way to eat it.

However, I’ve heard from a lot of people who enjoy this rhubarb sauce over ice cream or pound cake. I’ve tried it over ice cream myself now and it is delicious.

How to make Rhubarb Sauce with Jello

You can make this sauce with either fresh or frozen rhubarb. If you’re using frozen rhubarb, you will need to plan ahead and let it thaw completely.

Drain the excess liquid, but don’t squeeze out the rhubarb. I let mine thaw in a strainer over a bowl.

Rhubarb Sauce Ingredients

This recipe is simple, only 4 ingredients counting the water. You will need: 

  • Rhubarb
  • Water
  • Granulated Sugar
  • Strawberry Jello

Rhubarb Sauce Recipe

Place the rhubarb, water and sugar in a saucepan over medium heat. Bring to a boil and simmer for about 5 minutes until the rhubarb is tender. Remove from the heat and stir in a package of Strawberry Jello. Let cool. 

The amount of water in the recipe creates a sauce that is the consistency of applesauce when cool. It will seem runny at first, but the Jello will thicken it as it cools, especially after it is chilled in the refrigerator.

Feel free to adjust the amount of water in the recipe to thicken it to your tastes. The amount of sugar is adjustable too based on your tastes. This is a sweet sauce, thanks to the strawberry jello. 

Store your rhubarb sauce in the fridge for up to a week or freeze for longer storage.

I’ve only had rhubarb in sweet desserts, so I’m looking forward to trying this Rhubarb Barbecue Sauce and this Rhubarb Pulled Pork too.

    I have rhubarb in my garden and made this sauce. Turned out perfect! I would have never thought to have added jello!

    This is really great! Not sure we’ll use the whole batch before it turns. Do you know if this can be canned or frozen so I can put half up for later?

    About how rhubarb do you use for your recipe? Did you use a 3 or 6 oz. box of Strawberry Jello? My mom used to make rhubarb sauce with Jello, but I can’t find her recipe. Thanks!

    I always had rhubarb sauce at my grandmas but she never had a recipe. She just passed a week ago and my rhubarb is ready. I just made some in her memory of her, and success! I tried once before a few years ago and it was no good. I finally realized that i needed sugar and more water! Thank you for the recipe!

    I made this & it turned out extremely watery. Looks nothing like picture. I only added 3 cups of water. Is there any way I can fix this?

  6. Michelle says

    This is a disappointment. I love the taste of rhubarb, but after following the recipe to the letter, it tastes like strawberry sauce.

      I’ve made this sauce countless times exactly as written. Did it thicken in the fridge for you, Patty?
