Watermelon Slushie

Did you know that National Watermelon Day is August 3? In celebration of this wonderful holiday, I decided that it would be perfect to make a drink! Not only is it super hot outside, but it’s still summertime so this drink falls right into place. The best part about this watermelon slushie is that it’s refreshing and very easy to make.

Watermelon Slushie


  • 10 cups of seedless watermelon, cubed (frozen for at least 24 hours)

  • 1 lime

  • 1/2 cup water

Optional Ingredients: Sugar, Mint, Sparkling Water


  1. It’s important that your watermelon has been cubed and frozen for at least 24 hours. This keeps you from having to use ice in the recipe because the watermelon will substitute that.

  2. Allow the watermelon to defrost for about 5 minutes before adding to the blender. Then add the watermelon, juice of 1 lime, and water to the blender. If you want to add mint to your slushie, now would be the time to add it. That way it gets muddled in with the drink while blending.

  3. If the slushie is too thick, you can add sparkling water, until desired consistency is reached. This will make the drink nice and fizzy, which you can never go wrong with. If you don’t want the fizz, using normal water is fine as well.

  4. If you taste the slushie and you don’t think it’s sweet enough, you can definitely add sugar or even maple syrup. I’ve tried agave syrup, and that worked just fine as well. Doesn’t alter the taste at all. It’s hard to gauge just how sweet the drink will be because it depends on your watermelon. Taste the watermelon before freezing, and that should tell you if you’ll need sugar or not.

There are so many alternatives for this drink. You can add more lime for twang. Basil, if you’re fancy. You can also try adding different fruits to the mix, like strawberries, pineapples, or even mango! Whatever variation you choose, let me know so that we can enjoy this drink together. It’s also kid friendly, so perfect for a family day playing in the backyard, or a picnic.
