I hate the idea of throwing away food, so our freezer is packed with an array of chopped vegetables and fruits for use in future recipes, to include lots of watermelon!

Fortunately, frozen watermelon is exactly what we need for these daiquiris. You can keep them in a freezer-safe container or baggie for tasty slushies anytime.

This daiquiri is a bit healthier and doesn’t use any simple syrup. Feel free to adjust the sweetness level to your liking.

You just need four ingredients

Watermelon is a healthy, sweet base that adds volume to this cocktail without needing to add much else.

  • Watermelon: This recipe starts with frozen seedless watermelon. Of course, you can double the recipe if you’d like! Frozen is the key to getting the perfect frozen daiquiri texture.
  • Lime Juice: To add a bit of tang and zest, we will use a dash of fresh lime juice!
  • Sugar: Finally, we gotta add some sweetness! Watermelons are tasty as they come, but a little extra sugar helps the flavors to pop when frozen. You can substitute the sugar for a sugar alternative (like Stevia or Splenda) or go with a liquid sweetener like honey, maple, or agave.
  • Malibu Rum: Rum goes great with watermelon because this alcohol takes on any flavor added to it. I prefer Malibu, and sometimes I get a little wild and use coconut, but you could use whatever rum you like! Light rum or white rum will work.

To Freeze It…

To freeze watermelon chunks, lay chopped pieces on a parchment paper-lined sheet in a single layer. Freeze until hard, then transfer the frozen watermelon cubes to a freezer-safe container or baggie until you need them.

You’ll notice seedless watermelon actually has little seeds. These are much smaller and easier to eat than standard seeds, and they blend up just fine!

Let’s Blend!

This frozen cocktail is so easy to make. It’s also a super great recipe for using watermelon that you don’t think you will eat before it goes bad.

Step 1: Blend It All
Add all ingredients to a blender and blitz until smooth, scraping down the sides as needed to evenly combine.

Flavorful Additions

This cocktail can be customized with fun flavors and mix-ins. Here are just a few of my favorites.

  • Add herbs like mint leaves or basil.
  • Add heat with a pinch of chipotle pepper.
  • Use more citrus, like orange juice and orange zest.
  • Swap the rum for tequila or vodka.

    I believe I am going to try this next weekend. I am going to try it with Caribbean rum instead of the Malibu rum. I have the Caribbean on hand and don’t know that I’d like the coconut flavor in this drink.

    Yum!!! Had leftover watermelon in the freezer and this was perfect! Used Malibu coconut rum and all 4 tablespoons of sugar as I couldn’t remember how sweet my melon was. Next time will try it with tequila and agave. Keeper recipe, thanks!!

    Tried this for the first time for 4th of July weekend. So refreshing! Even my beer-drinking hubby loved it and told me to add it to our recipe box for future occasions.
