Refreshing Watermelon Margaritas You Need to Make Today

September 12, 2020

These watermelon margaritas are a twist on a classic cocktail recipe that is perfect at the end of summer when watermelons are at their ripest and sweetest.  

Watermelon Margarita

Labor Day weekend is always bittersweet for me. I love getting three days instead of just two to rest  and relax and work on weekend projects. However, living in Northeast South Dakota, Labor Day signals the end of summer–the end of long days of sunshine, warm weather, and time spent outside. It marks the official turn to cooler temps, early sunsets and moving indoors to hibernate. Usually, by the end of September, temps have dropped from the 70s and 80s, to 40s and 50s. By the end of October, it will be close to the 30s nearly everyday. So soaking up these last summer days are essential!

This year has been weird (clearly, thanks, Rona), so we’ve spent so much time entertaining ourselves, and I’ve discovered I have a love for tequila and a good margarita. I’ve had plenty of time to figure out how to make a fresh and zippy marg, like this strawberry jalepeno marg.

The Deets

Last week at work, one of my coworkers brought in a truck bed full of large ripe watermelons. The one I got had to be at least ten pounds–okay I’m not exactly sure how big, but just like old men talk about the big fish they caught that got away, this is the biggest watermelon I had ever seen. We chunked half of it and filled a giant bowl (took us two days, and consuming it during every meal to finish it!), and we still had a second half to do something with. (Watermelon margarita recipe enters stage left.)

We chunked the second half of the watermelon, removed as many seeds as we could by hand, and put it in our blender (it’s nothing fancy, just a basic blender from Hamilton Beach. I don’t blend a ton of things, so this works really well.) added lime juice, tequila, triple sec,and ice, and wham, bam, thank you ma’am, we had a refreshing watermelon margarita. 

How to Level Up Your Margarita

The taste of this watermelon margarita is a little less zippy, but still very refreshing and so good. I’m not a fan of pre-made mixes with lots of sugar, so these watermelon margaritas have the perfect amount of natural sweet. If you need more sweetness in your life, I would add this agave. What is agave? Agave is a natural sweetener that is actually the main ingredient in tequila.

Watermelon Marg

The most labor intensive part of this whole drink is cutting up the watermelon and removing the seeds. Two things would make that easier: first, buy watermelon already chopped, or second, buy a seedless watermelon. Since mine was given to me, I’m not going to complain. 

We made two drinks at once, and after our first round of cocktails, I realized I need a lot more lime juice (I love things tart), but you do you, and make this to taste. 

Margaritas are typically served in traditional margarita glasses, however, I used these simple cocktail glasses I purchased through Amazon. I also salted these rims, because the salt makes the marg! This is the salt I use. I am on my second salt rimmer container this summer–sorry not sorry.
