There is nothing more refreshing than a Watermelon Mint Martini on a hot day or warm evening. It just screams summer and this vodka cocktail is also screaming good.

It is sweet, fun, and fancy. The addition of mint adds a bit of coolness which is a great complement to the subtle flavor that watermelon offers in this cocktail recipe.

Besides being completely delicious, the gorgeous pink color is so tempting. Offer it along with a Pink Mocktini so everyone can have a fun drink to sip all summer long.

Ingredients for a Watermelon Mint Cocktail

I love a good martini and I prefer vodka over gin any day of the week. This recipe would be no exception, vodka all the way! This calls for regular plain vodka, no fancy flavors here.

The key to the best watermelon cocktail is fresh ingredients. This is made with real fresh fruit & herbs - not just flavored vodka or syrups. If you love a lemon drop martini, this is your kind of drink.

Watermelon mint martini ingredients on the table.

Fresh Watermelon - seedless variety is best
Vodka - use your favorite regular brand - Tito's, Grey Goose, Kirkland, Absolut, Ketel One, etc.
Lemon Juice - freshly squeezed is best
Simple Syrup - for added sweetness
Fresh Mint - the leaves add a cool flavor to offset the sweetness
Super Fine Sugar - for rimming the martini glass

There are also seedless varieties so this fruit without seeds is a great option for straining to make cocktails.

How to Make a Watermelon Martini

This recipe makes enough for two glasses. This is what will fit in a standard cocktail shaker. The one I have works great to make the drink cold but if you don't have one, use a large mason jar with tight-fitting lid.

Here are the easy steps for making a vodka martini with fresh watermelon:

Prep the Glasses
Blend & Strain the Watermelon
Combine in Cocktail Shaker
Pour & Enjoy

See the step-by-step instructions with photos below plus the recipe card at the end of the post.

1 - Prep the Glasses

Prepare two martini glasses by rubbing the lemon slice around the edge to moisten. In a shallow dish pour the superfine sugar, dip the martini glasses, and roll around to coat the lemon edge with sugar.

2 - Blend & Strain the Watermelon

In a blender or single-serving Ninja capsule, combine the watermelon, simple syrup, lemon juice, and mint. Blend on high until liquified.

Using a fine-mesh strainer, strain into a martini shaker. This will remove the foam that will be created and leave nothing but pink liquid.

This recipe uses just a bit of watermelon so if you have plenty leftover you can freeze watermelon to make this recipe again later. Better yet make a batch of my Watermelon Salsa (pico de gallo) for more party recipes.

3 - Combine in Cocktail Shaker

Add the vodka and ice cubes to the shaker. Place the top tightly on the shaker. Shake vigorously for about 15 seconds.

4 - Pour & Enjoy!

Remove the small shaker lid to expose the strainer part of the shaker, and pour ½ in each of the 2 prepared martini glasses with a sugared rim.

** optional, garnish with mint leaves and/or watermelon wedge.

Sip & Enjoy! Great to serve at backyard cookouts, for 4th of July, or any summer gathering. Pair it up with my Peach Martini Recipe & give your guests a variety.
