With just three ingredients, this Watermelon Slush recipe is not only easy to make, it’s healthy too!
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. 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. I found out while doing research for our Copy Cat Sonic Slushes with Pop Rocks that the restaurant uses 5 pounds of sugar for every gallon of water. FIVE POUNDS! No wonder these dang love handles won’t go away!
This watermelon slush is just as tasty, if not tastier, and only has 1/2 cup sugar per batch; and each batch makes 3-5 servings depending on size. I feel a whole lot better letting my kids drink this version, obviously.
Watermelon Slush 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 them themselves! All you need is:
- Watermelon
- Sugar
- Lemon Juice
- Water
Pro Tips:
- To make prep for these slushes easy I like to buy an extra watermelon when they’re on sale (or when they are $4.99 at Costco) and dice up the second 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, or if it’s too tart add a little sugar at a time until desired sweetness is achieved.
- Best if served promptly after preparation.
