When you want a taste of summer mix up a refreshing Watermelon Vodka Cocktail! Top with a sprinkling of lime zest and you will feel like summer never ended.

We like to serve these drinks with easy to make spicy food like our Jerk Chicken or our Roasted Shrimp with Chipotle Sauce. Spicy food pairs perfectly with this sweet watermelon slush!

Just 4 ingredients for Watermelon Vodka Cocktails:

  • Watermelon
  • Vodka
  • Simple Syrup (or sweetener of your choice)
  • Lime Juice and Zest

How to make Watermelon Puree:

I like to puree a lot of watermelon during the summer when it is plentiful, and then keep it in the freezer (so I have it all winter for drinks).

To puree:

  • Chop your melon into chunks and remove the rind
  • If you use a super-powerful blender like a Vitamix you don’t need to remove the black seeds because it all gets pureed. If you are hand mashing it or using a regular blender you should try and remove most of the seeds
  • Puree on high for about 30 seconds
  • Once the watermelon is pureed you can store it in small freezer bags, or in glass jars, in portions
  • If you want your puree to be clear strain it through a fine sieve

There are lots of fun ways to use fruit purees, such as in daiquiris, margaritas Mojitos, martinis, and lemonade.

How to make Watermelon Vodka Cocktail:

This cocktail tastes best when it’s very cold so keep your vodka in the freezer if possible. If you have time, also chill your cocktail glass. If preparing everything at room temperature I recommend adding 2-3 ice cubes to the blender to chill the ingredients down.

  • Chill all ingredients
  • Use chilled glasses, if possible
  • Cut rind off of watermelon. Leave a few pieces with rind for a garnish
  • Zest a lime and then cut in half and juice it
  • Blend watermelon puree until smooth
  • Add vodka, simple syrup and lime juice to the blender and mix for about 15 seconds
  • Pour into chilled glasses
  • Sprinkle with lime zest and garnish with a watermelon wedge

Ingredient Tips:

Watermelon can be very sweet or a bit bland, depending on the time of the year, so be sure to taste test your puree. If it’s a little bland you can add a little more simple syrup to this cocktail to sweeten it up. For more details on making easy homemade simple syrup refer to our Blackberry Champagne Cocktail recipe.

Be sure to use freshly squeezed lime juice, but don’t forget to zest your lime first to use for garnish. The lime juice is important to this watermelon and vodka cocktail because it helps balance the sweetness of the watermelon.

    Love this flavor combo! And thanks for the tip to puree watermelon in the summer and freeze – such a great idea. I’d skip the syrup in this recipe as I prefer my cocktails on the less sweet side, but I will definitely be trying it out when good watermelons hit the stores again!
