Watermelon Mojito

If you like a light tasting, refreshing cocktail this is the drink for you. If you like mojitos, this is the drink for you.

The cool taste of watermelon mixed with sweet rum, mint and a fizzy soda makes this an unforgetable cocktail. Mix this up for friends and you’ll be very popular. I should add a disclaimer: Plan to make more than you think you’ll need. You’ll need them.

I usually add sugar water to my mojitos. I’ve been trying to cut a few calories and a friend suggested this Fresca. (This is not a sponsored posts, by the way!) Fresca is much like tonic water or club soda. It has fizz, is neutral is flavor and zero calories. It’s perfect to top off the alcohol and muddled watermelon and mint.


The process I use for making this drink is simple. I muddle watermelon, mint, lime and ice in a shaker. If you’ll add the ice with the watermelon and mint, it helps to break the fruit down and release the flavors.

Next, pour in the rum and shake to combine.

In a glass that has been filled with ice, fill the glass half to 3/4 with the watermelon mixture and top it off with the Fresca. Stir gently to combine.

Two things to remember, Fresca is carbonated, you do not want to add it to the shaker and shake. Trust me. Remember that soda you dropped then opened?

You can substitute tonic water, club soda, Sprite, 7-up or any carbonated beverage that is neutral in flavor for the Fresca. It won’t be exactly the same, but will be close to my recipe. I do recommend Fresca if it’s available in your area.

For mocktail, simply leave out the rum. It’s a refreshing drink that doesn’t have to include alcohol!

  3. Hi Paula,

    I was in an e-mail from Arlene at “Flower On My Face”. This was one of the drinks she featured.

    I am not much of a drinker, but this does sound soooo good. I noticed that there are not any amounts of item used showing….example 1. cups of watermelon.

    I was hoping you would be able to fill in the amount of each item needed. I saw that this served 4….would be a big help. I will be going down to my Summer Place in “The Valley” in South Texas and I thought this would be a good way to start off the stay.

    Thanks so much for your help on this.

    Have a good one.
    Carpe Diem

    1. Hi Roy, I don’t know what happened to that and it won’t allow me to fix it there where it’s supposed to be, but I added it in the notes. It’s a great hot weather cocktail, my favorite. Hope you enjoy it.

      1. Thanks Paula. I can’t wait to make it and give it a try…..I’m sure I’m gonna luv it!

    1. I think blending will be fine. You just really want to get the flavors out of the mint and watermelon so it should work beautifully!
