Watermelon Slush with Lime and Coconut

If you look up the definition of summer, you’ll probably see a picture of a watermelon. It’s one of the true pleasures of the season. Rich in heart health boosting lycopene, watermelon is an excellent source of vitamins A and C. And despite the sweetness, a cup of watermelon has just 45 calories. Hard to believe but it’s true. This is all good, but if you’re like me, you eat it because it tastes good.

I tend to buy too much of it and end up with extra. A few years ago in my single girl apartment, in July I started freezing chunks of leftover watermelon. After eating as much as my belly could take right off the rind, I’d make watermelon salad then a frozen dessert (a granita).

Because I can’t let good watermelon go to waste, I cut the watermelon and freeze the cubes. I can use the frozen fruit as ice cubes, but I love to toss them into a blender to make this easy watermelon slush. You can add mint, basil or other flavors to mix it up. This method will also work well for cantaloupe, honeydew, and pineapple.

Before I get to the recipe, can we take a moment to appreciate just how pretty it is? 😍

  • 2 cups frozen ripe watermelon cubed
  • Juice of 1 large lime
  • 1-1½ cups coconut sparkling water (I used a can of coconut LaCroix)


  • Add the ripe watermelon cubes and lime juice to a blender. Blend on high until smooth.
  • Pour in 1 cup sparkling water. Blend just to combine. Add more sparkling water to reach the desired consistency.
  • Pour. Enjoy!
  • NOTE: I didn't need any sugar in this recipe because the watermelon I got was very sweet. Feel free to add a little honey or your favorite sweetener if your watermelon is not super sweet.

      Haven't tried it with pineapple yet but cantaloupe and honeydew melon both work well! I'd try pineapple but add a bit more liquid to the mix Reply

      I keep a stash of melon cubes in the freezer all summer long for slushies or fruit "ice" cubes in water :) Reply

      When watermelon is that ripe, there's no need for sugar. It was sweet as candy! :) Reply

    This is surely a summer pleasure! Not sure if I can find sparkling coconut water but how about adding some sparkling orange or peach juice instead? Reply

      I used Coconut Flavored Lacroix! I think lime or peach flavor would be delicious in it! I've never tried it with orange but I bet it could be a fun combo. Reply
