Nothing says summer more than biting into a nice, juicy slice of watermelon. Last month when the temperatures were too hot to handle, we spent some time in the kitchen coming up with fun new drinks.

Watermelon Slushie

My kids' favorites were the Jamba Juice Caribbean Passion Copycat drinks and the Copycat Sonic Slush. Mine was this watermelon slush.

Watermelon Slush

We LOVE slushes. The only downfall to these cool drinks is the sugar content. While researching for our Copy Cat Sonic Slushes with Pop Rocks, I found out that the restaurant uses 5 pounds of sugar for every gallon of water. FIVE POUNDS!

This watermelon slush is just as tasty, if not tastier, and only has ½ cup sugar per batch; and each batch makes 3-5 servings depending on size. I feel a whole lot better about letting my kids drink this version, obviously.

If you like Watermelon in other forms, you should try this Watermelon Feta Salad or  Fresh Watermelon Cake too.

Watermelon Slushie Recipe Ingredients

The best thing about this slush is how simple it is to make. Other than cutting the watermelon to freeze, my kids can make it themselves. All you need is:

  • Watermelon
  • Sugar
  • Lemon Juice
  • Water

How to Make Watermelon Slush Recipe

Simply place all your ingredients into a blender or food processor and blend until smooth. Best if served immediately.

Watermelon Slushy Pro Tips:

  • To make prep for these slushes easy, I like to buy a second watermelon when they're on sale (or when they are $4.99 at Costco) and dice up the extra one. I measure out the pieces into 5-cup portions and freeze them in Ziploc bags. This way, whenever the hankering for a slush comes on, it only takes 2 minutes to make.
  • If the slush is too sweet for you, add a few more cubes of watermelon. If it's too tart, add a little sugar at a time until desired sweetness is achieved.
  • Best if served promptly after preparation.

    I served this at a birthday party, and it was a huge hit! Everybody loved it, especially since it's so hot outside. It makes a nice change from sodas.
