Ingredients for a watermelon slushie

This watermelon slushie is the perfect summer treat because it’s laid-back and no-frills. All you need is 3 ingredients, plus ice! Here’s what you’ll need to have on hand:

  • Ripe watermelon: Use only ripe, in season watermelon for this recipe.
  • Lime juice: Fresh squeezed lime juice brings a welcome tang and brings out the sweet, tropical flavor of the melon.
  • Sugar: Just a hint of sugar heightens the flavors in this drink.

All you’ll do is blend these ingredients until they form watermelon juice, then add ice until a slushie texture forms. Here are a few things to note about the texture!

Achieving the perfect slushie texture

The texture of this watermelon slushie is icy yet loose. It’s not a watermelon smoothie, which has a thicker, creamier texture. Here are a few things to note:

  • Want it frostier? You can add a few more ice cubes. But the more ice you add, the more diluted the flavor becomes. Don’t add too much ice! When we tested with 4 cups of ice instead of 3, the flavor was too mild.
  • Enjoy right away! The slushie texture is perfect right out of the blender. It does melt quickly, so make sure to enjoy it right after you make it. It doesn’t store well!

How to find a ripe watermelon

The most important thing for a watermelon slushie? Find a ripe watermelon! Don’t even attempt to try this with an unripe melon: no amount of sugar can make up for the lack of flavor. Here’s what to know about finding a good melon:

  • Shop in watermelon season. It’s the best way to find a sweet, juicy melon.
  • Look for the field spot. Most watermelons should have a patch on the bottom, which is where they were resting on the ground before being picked. If the patch is yellow, the watermelon is ripe (if it’s white, it’s unripe).

Why to drink a watermelon slushie

Why make a watermelon slushie? You might not need convincing, but here’s what we think:

  • Watermelon is high in lycopene, an antioxidant, which studies show could help curb your risk of cancer and diabetes as part of a healthy lifestyle. It’s also got loads of vitamins. (Source WebMD: Health Benefits of Watermelon)
  • It’s very hydrating. Watermelon is 92% water, so it’s super hydrating!
  • It’s frosty and delicious. The best reason? It tastes incredible.

Frequently asked questions

Do I need to seed the watermelon before blending?

No need for a seed-picking marathon! Use seedless watermelon for this recipe. Most watermelon slushie recipes blend the entire fruit, seeds and all. The seeds are tiny and don’t affect the texture.

My watermelon isn’t very sweet. Will the slushie still be tasty?

Use only ripe, sweet watermelon for a watermelon slushie. You can adjust the sweetness of your slushie by adding extra sweetener.

Is this slushie healthy?

Watermelon is a naturally hydrating fruit packed with vitamins and antioxidants. As long as you don’t add excessive sugar or processed ingredients, it’s a healthy and refreshing summer treat.
