Super Refreshing Rhubarb Strawberry Lemonade Slush

Welp, I confess the heat outside is getting to me already.  We haven’t even officially reached summer, which is June 20th, but we have had temperatures in the mid-90s.  It’s the perfect time to make some rhubarb strawberry lemonade!

If this is your first time reading my blog, you may not know that I have a bit of an obsession with rhubarb.  I shared the most delicious rhubarb bars, rhubarb raspberry ice cream sauce, rhubarb jam, and a guide on growing rhubarb in case you missed it.

This is a PERFECT time to whip up some ice-cold refreshing Strawberry Rhubarb Lemonade Slush.  This drink is tangy and hits the spot for summer.

We like to keep a gallon of this slush in the freezer for those hot days.   To serve the drink, you’ll scrape or scoop some of the frozen slushes out and into a glass.  You’ll want to add some carbonated drink to your glass.  I prefer proportions of 2/3 slush to 1/3 carbonated drink.  We always used to add Sprite or 7-Up to our rhubarb slush.  More recently, I have switched it up to have a lighter drink that is not syrupy.  If you’re like me, you may want to opt to add sparkling water to your slush when serving up a glass (my favorite is lemon-flavored La Croix).

I’ve seen other rhubarb slush recipes, and they all call for a ton of sugar.  My version has far less sweetener than most through a little trick called True Lemon Lemonade.

We keep our cupboard stocked with a box of these packets, which contain a tiny amount of sugar and stevia.  I also use TrueLemon in my Low Carb Strawberry Lemonade Pie, so check that out if you are looking for a citrus dessert that is low on sugar.  In my humble opinion, this concoction results in the PERFECT level of sweetness.

One more note before I get to the recipe…

You will need to extract the rhubarb juice out of the rhubarb by cooking about 8 cups of rhubarb in 2 quarts of water.  Once the rhubarb is softened, you will strain the rhubarb out, so your slush is pulp-free.  We also have a juicer and I may try using that in the future but this method of extracting the juice is perfect for every kitchen.



Super Refreshing Rhubarb Strawberry Lemonade Slush

Prep Time 5 mins
Cook Time 10 mins
Total Time 1 d 15 mins
Servings 16 persons


  • 8 cups rhubarb cut up
  • 2 quarts of water for cooking rhubarb
  • 1 ½ cups granulated sugar
  • 3 ounce box of strawberry Jell-O
  • 6 packets of True Lemon Lemonade
  • Sprite 7-Up, or Sparkling water


  • In a medium kettle, cook the rhubarb and water until the rhubarb is tender.
  • Strain the rhubarb so only juice/water remains.
  • Mix in the sugar, Jell-O, and lemonade packets.
  • Pour mixture into a gallon bucket (we use an old ice cream pail)
  • Add enough water to the mixture to make 1 gallon of slush.
  • Freeze at least 24 hours prior to serving.
  • To Serve: Scrape out the slush to fill a drinking glass ⅔ rds full. Pour your preferred carbonated beverage.
  • Stir and enjoy!


Sparking water such as LaCroix is my absolute favorite carbonated drink for this.  I recommend you try that if you find that 7-Up or Sprite is too sweet for your tastes.
