Need an intensely refreshing drink that takes just minutes to go from kitchen to sipping? Get out of the sun, get into your kitchen, and try one of these watermelon rum lemonade slushies inspired by Celebrating Sweets!
You can’t have a festive summer gathering without delighting your hot and thirsty guests with a fun, fruity, ice-cold drink. Slushies are the ultimate beat-the-heat summer refreshment, and all you need to make them is a few good ingredients and your blender.
Though our watermelon rum lemonade slushie recipe takes little time to prepare, you do need to plan ahead. Frozen chunks of watermelon are the primary ingredient for this drink, which means you’ll have to get your melon in the freezer in advance (instructions below).
When it’s time to refresh your guests, place frozen watermelon chunks, lemonade and rum in a blender and blend on high speed until well combined. Add crushed ice and continue blending until you get that slushie consistency. Immediately pour the mixture into glasses.
Don’t just stick a straw in your slushie: Turn this quick summer treat into a resort-worthy drink. Add two fresh mint sprigs to the top of each slushie, then slip a lemon wheel on the side of each glass and serve.
Making slushies for your whole family? For a non-alcoholic, kid-friendly version, just leave out the rum.
How to freeze watermelon
Start with the freshest, sweetest watermelon you can find (buy seedless to save time). Cut the watermelon in half lengthwise. Use a melon baller to remove watermelon flesh, or use a sharp knife to cut watermelon into chunks. Discard the rind or save it for another use. Place watermelon balls or chunks on parchment-lined baking trays and freeze until solid. Use them immediately, or transfer them to freezer bags or freezer-safe containers and seal.
