There is nothing I love more in the summer time than slushies… especially these watermelon slushies! They are the perfect frozen drink on a hot summer’s day or whenever you are craving a fruity and cold treat.

The ripe watermelon combined with lime and sweet ginger ale make the PERFECT summer flavor combination. And if you are new here, we love adding non alcoholic spirits to our drinks so expect some fun mocktail suggestions below!

For any leftover watermelon I highly recommend these Watermelon Popsicles, or this Watermelon Mojito Salad. There is no alcohol in it, but the flavors are amazing!

Watermelon Lime Slush Ingredients

  • Frozen Watermelon Chunks
  • Ice
  • Ginger Ale
  • Fresh Squeezed Lime Juice
  • Cane Sugar
  • Water
  • OPTIONAL Non alcoholic spirits (suggestions below)

Equipment Needed

  • Blender or Food Processor: I use a Ninja because it is high powdered and doubles as a blender/food processor. You can use it for more than blending drinks which I love.
  • Glassware: I use geometric lowball glasses but you can use hurricane glasses, margarita glasses, or whatever you like.
  • Straws: These are essential for enjoying any frozen drink. I prefer to use eco-friendly paper straws.
  • Citrus Juicer: You definitely need a juicer to get the most out of your limes.
Ingredients are frozen watermelon, lime juice, water, ice, and ginger ale soda.

How to Make Watermelon Lime Slushies

First things first, cut your fresh watermelon in small pieces and place in a single layer on a cookie sheet. Throw that in the freezer overnight and make sure your watermelon chunks are frozen solid before blending.

Back to the Watermelon Lime Slush, this drink is so easy! Literally all you do is throw everything into your blender and blend until smooth. There is no fancy method and you can’t mess it up.

Troubleshooting Your Watermelon Lime Slushie

Too thick? Add a tablespoon more of ginger ale or lime juice.

Too thin? Add a 1/4 more of frozen watermelon.

Not sweet enough? Some watermelon isn’t very sweet so you may want to add more cane sugar. I recommend a tablespoon at a time.

Tips For The Very Best Watermelon Lime Slush

  • Use freshly squeezed lime juice. Store-bought lime juice just isn’t the same.
  • Blend it up as you are serving it. This slushie doesn’t store well in the refrigerator or freezer and it melts quickly. Serving it as you need it, and immediately, is best.
  • Garnish is everything. To make this slush even more fun, add mini watermelon slices, lime slices, and fun straws.

Make It A Mocktail!

Frequently Asked Questions (FAQs)

What if I don’t have a blender?

For this slush a food processor of any size works just as well as a blender. You will definitely want a blender or food processor to make this though.

Can I add alcohol to my Watermelon Slushies?

Yes, of course! Vodka, coconut rum, or even tequila would taste delicious in this!

Do the watermelon chunks have to be frozen?

Yes, yes, yes! The slush consistency comes from the combination of frozen watermelon and ice. If the watermelon chunks are at room temperature or even refrigerated, all you will have is a liquid juice.

    Soooo good! Made these to drink while at the pool at my parents’ house. We all loved them!! I added a little extra ginger ale and lime juice to thin them out.
