Watermelon Slushie

July 24, 2025

There’s no better way to cool off on a hot day than with a Watermelon Slushie. This chilled, refreshing drink is packed with the natural sweetness of ripe watermelon, making it the perfect thirst-quenching treat. The best part? It’s incredibly easy to make, requiring just a few simple ingredients to create a fruity, icy delight that’s sure to satisfy.

Start with fresh watermelon, its high water content makes it the ideal base for a slushie. Cut it into chunks and remove the seeds. For an extra burst of flavor, you can add a squeeze of lime juice or a handful of mint leaves to give the slushie a refreshing zing. A touch of honey or agave syrup can add sweetness if your watermelon isn’t quite ripe enough, but this is entirely optional.

To achieve that perfect slushy consistency, simply blend the watermelon with ice. The ice helps give the slushie that smooth, frosty texture, while the watermelon’s natural juiciness ensures it’s not too thick. You can adjust the amount of ice depending on how frozen you want your drink to be. For a little extra depth, consider adding a splash of coconut water or sparkling water to keep it light and bubbly.

Serve your Watermelon Slushies in chilled glasses, garnished with a sprig of mint or a thin slice of lime on the rim. If you’re feeling adventurous, top with a few chunks of fresh watermelon or even a drizzle of lime zest for an added pop of flavor.

These slushies are perfect for hot summer days, poolside hangouts, or even as a fun and fruity drink at a party. They’re not only delicious and refreshing but also naturally hydrating, making them a healthy and tasty alternative to sugary beverages.

Whether you’re sipping it on its own or pairing it with a meal, Watermelon Slushies bring the perfect balance of sweetness, coolness, and fruitiness to any occasion.

    Is it really that simple? Just watermelon and ice? 🤔 I expected something more fancy.

      Honestly, it could be better with more ingredients. How about some mint or coconut milk? Just watermelon seems too plain.

  8. User avatar benton.hammes81 says:

    Pretty good, but too tart for my taste. Maybe next time I’ll add more sugar.

    Watermelon should NOT be blended! It just makes it mushy. #disappointed

    1. User avatar antone.daniel32 says:

      I get what you’re saying, but blending actually makes it a refreshing drink! You might just need to try a different ratio next time.

    2. User avatar Deena Rempel IV says:

      5 stars
      Nah, blending is the best way! Who wants to eat it all chunky? Slushies are where it’s at! 🍉

    I tried it without sugar and it was too sour for me. Maybe better with a bit of sweet.

    1. User avatar huey.bradtke says:

      4 stars
      I totally agree! A little sugar can really balance out that tangy flavor. I always add a bit too.

      Try honey instead of sugar! Sweetens it up without the granulated stuff.

    Not bad, but I think yoos should add more sugar. My slushie was too tart.

    Yummy! I added some mint leaves too. Makes it even better!

  18. User avatar Zaphod Beeblebrox says:

    Tried this and it was too watery for me. I think it needed more watermelon or less ice.

    1. User avatar stanton.smitham61 says:

      4 stars
      I had the exact opposite experience! Mine was super thick and refreshing. Maybe you blended it too long?

    2. User avatar hugh.schmeler1990 says:

      Less ice makes sense, but more watermelon? How do you fit that in the blender? 🤔

  19. User avatar terresa.hayes says:

    I followed the recipe, but it didn’t taste as sweet as I expected. Maybe I needed to add more sugar.

      You probably need to use a riper watermelon! That would make it way sweeter.

    It’s not really slushy. My blender couldn’t handle the ice cubes. 😕

    1. User avatar renata.rau says:

      Sounds like your blender might be too weak for this! 🙁 Did you use a high-speed one?

      Maybe try cutting the ice into smaller pieces first? My blender handles it fine that way!

    Watermelon is the best fruit for summer! Slushie sounds good.

    Not convinced. How is this even a recipe? Just blend fruit and ice.

    1. User avatar Meriadoc Brandybuck says:

      Blending fruit isn’t cooking! This is just lazy. Where’s the effort? 🤷‍♂️

    How much lime juice exactly? I squeezed half a lime and it was too sour.

    1. User avatar suspiciousCommentator says:

      4 stars
      I think it says 1 tablespoon of lime juice! You might have used too much if you only squeezed half a lime. Try the full tablespoon next time.

    2. User avatar smartestRedditor says:

      3 stars
      Half a lime is not enough for that recipe, it gives its zest! Maybe try 2 tablespoons next time?
