You’re in for a treat! I’m teaching you how to make this watermelon basil cocktail. Served up in a martini glass, it’s as beautiful as it is delicious. If summer had a flavor, this might be it! 

The base of the cocktail is watermelon juice muddled with fresh basil. To achieve this, you mash up a few pieces of watermelon with a couple of basil leaves and then strain it to remove the pulp and seeds. What you end up with is a delicious juice that tastes like a summer melon with just a hint of basil.

I love herb and fruit cocktails like this Strawberry Thyme Martini, Strawberry Basil Martini, or Pineapple Basil Sangria! Yum!

I saw this cocktail on a menu a few months ago and have been dying to give it try. I wasn’t quite sure what the restaurant used to make its version, but as soon I read the name, a few ingredient ideas were dancing in my head. 

After lots of testing, I’m pleased to tell you that the resulting libation is quite delicious. I think you’re going to love this watermelon basil cocktail as much as I do! 

Why You’ll Love This Cocktail

  • It’s unique but familiar. While you’ve probably never had a watermelon and basil cocktail before, I assume you are familiar with both of its ingredients. Therefore, it’s approachable but still special. 
  • You only need four ingredients. I love a drink recipe that’s not overly complicated. With a limited amount of ingredients, this cocktail couldn’t get much easier to make. 
  • It’s ideal for summer, but you can enjoy it whenever. I think this is a delightful recipe to enjoy during warmer weather months when watermelon and basil are both in season. However, you can certainly enjoy this cocktail any time of the year. I think it would be lovely for a bridal/baby shower or even to celebrate mom on Mother’s Day

Ingredients

  • fresh watermelon – This is where a lot of the flavor comes from in this cocktail recipe. Be sure to use a watermelon that’s fresh and full of flavor. 
  • basil leaves – Fresh basil leaves are a must here. Pick them up at the store or grab them out of your cocktail garden. 
  • vodka – To make sure the watermelon basil flavor stood out in this cocktail, I relied on vodka for the main liquor. (When you’re making any martini, go with a top-shelf vodka for the best results. As of late, my brand of choice is Tito’s.)
  • St-Germain liqueur – This sweet liqueur, with flavors reminiscent of pear and lychee, perfectly complements everything else that’s happening in this martini.
