One dream I thought for sure died with my twenties was a Watermelon Margarita. I just knew I would never be able to “afford” that many calories again. Thankfully, I was wrong!

Honestly, I didn’t even realize how incredible a fresh Watermelon Margarita could be after years of drinking pre-mixed margaritas at restaurants! Puréed fruit is sweet enough to limit the amount of agave nectar. It’s so much more amazing than the super sweet pre-mixed margaritas.

Watermelon Margarita

I was getting ready to make a batch of skinny margaritas for the weekend, and realized I needed to share one of my favorite variations with you. A fresh Watermelon Margarita. It’s a taste of summer. It’s so refreshing, especially without a salt rimmed glass.

It is perfectly presentable with a little watermelon wedge to garnish the glass.

How Many Calories are in Watermelon Margaritas

There are just 112 calories in a Watermelon Margarita! That’s just one of the things that make them so amazing! It’s so fresh and flavorful yet naturally sweet.

Secrets to Amazing Margaritas

Use Crushed Ice

Using crushed ice is so simple, but really makes a difference. It waters the margarita down taking out a hint of sour. In the name of research, we tasted a margarita made with cubed ice next to a margarita with crushed ice. The difference is astounding.

Sometimes, it’s the little things. However, at home, we often make them with cubed ice out of ease. Either way, you’ll love these margaritas!

Fresh Lime Juice

Purchasing lime juice will do, too. I have a juicer attachment for my mixer that makes fresh juice a breeze, but I also frequently use bottled lime juice. Either way it’s significantly better than a mix.


Agave naturally sweetens watermelon margaritas, without all the calories! If you prefer, you can use simple syrup.

Great Tequila

Any will “do”, but the better the tequila, the better the flavor. I love using Patron Silver, Camerena Reposado, Camerena Silver or Altos. The tequila you choose can enhance or detract from the flavor.

How to Rim a Margarita Glass

  • Rub a lime wedge around the rim of a glass.
  • Dip rims in thick flakes of kosher salt or margarita salt.

How to Make a Watermelon Margarita

  1. Purée watermelon in a food processor. Blend until smooth.
  2. Combine watermelon juice with tequila and agave nectar.
  3. Serve over ice cubes or crushed ice in prepared glasses if you prefer salt on the rim.
  4. Garnish with fresh lime wedges or a watermelon wedge.

You can also combine all ingredients with ice and shake in a cocktail shaker. 

How to Make a Frozen Watermelon Margarita

After puréeing the watermelon, add tequila, agave nectar and blend with ice. It makes an amazing Frozen Watermelon Margarita that’s perfect for poolside get togethers, barbecues, boating and more. Either way, it’s low calories and tastes fabulous!
