Frozen Rhubarb Slush is the refreshing gift of late spring and early summer. Summer is finally upon us and it surely took its sweet time showing up.   I am not complaining.  This is what we mid-westerners wait for, our beloved few days summer.

What is this?

We have to put up with what seems like 8 months of winter yet even with the hassle of all that snow and bad weather, it is well worth the wait for the beautiful summer days that we are in the midst of.  During these glorious daylight hours, I like to sit back with a nice cold refreshing beverage.  My cocktail of choice for this day was rhubarb slush.

Fresh rhubarb from the vine is always best for this frozen rhubarb slush drink.

I was first introduced to Gloria’s rhubarb slush nearly 20 years ago.  Gloria is a tried and true farm girl.  She is great at whatever she does.  Her gardens are plentiful.  Her food is always delicious and she bakes like a dream.

However, when this drink was first offered to me, I wasn’t really sure what to think.  At that point in my life, I didn’t even know what rhubarb was.  But what I was certain of is that if this was something Gloria put together, then I knew that it was going to be good.

For me, it was love after the first sip.  The drink itself is sweet, tart, and refreshing.  The nice thing about it is that it screams summer in a glass.  It can be served with or without alcohol.  Our kids flip when they know that we are making up a batch of the slush.

 This frozen rhubarb slush is very quick and easy to put together.  The longest part of the process is waiting for the slush to freeze solid.  As you might guess, this just happens to be the most annoying part of the process as well.  Talk about wistful anticipation…

We just served this frozen refreshment over the Independence Day holiday, at our small cottage on a small lake in the middle of Nowhere, Wisconsin.    Our guests had a somewhat  baffled look on their faces when I told them what we were serving as a beverage but let me tell you, they too were hooked with just one sip.   This is the stuff that gives cause to make double batches; next time I’ll know better.

Do your palate a favor, the next time you see some rhubarb in the store or at a farmer’s market, pick some up and give this recipe rhubarb slush a whirl.   You can thank  Gloria for this delicious drink.  -Scott

Rhubarb Slush is a refreshing gift of the spring season.
Prep: 10 minutes
Total: 1 hour
Yield: 8 servings


  • 6 cups rhubarb, diced
  • 1 quart water
  • 2 cups sugar
  • 6 oz lemonade concentrate
  • 6 oz orange juice concentrate
  • 3 cupa cold water


  • In a stock pot add diced rhubarb to 1 quart of water. Cover and cook over medium heat until rhubarb is softened.

  • Add the sugar to the juice while it is hot and stir to dissolve the sugar.

  • Pour into a container, cover and place into freezer to freeze.
  • When ready, serve the frozen rhubarb mixture loosely parked in a glass with white soda. An ice cream scoop works great for this.
  • For an alcoholic version, add a little vodka to your glass and follow the instructions listed above.

    Other great additives:
    Also mixes well with rum, whiskey or brandy. Can also substitute white soda with squirt or 50/50.

    Mix it up! Lots of combinations! ❤️

    I’ve made this twice now. I substitute the sugar with Splenda to lower the sugar content. I also freeze it in ice cube trays. My family loves it.
