I think the most challenging part of this pregnancy for me is being thirsty ALL THE TIME. 

The amount of water I drink feels insane (close to 100 oz a day!) and I am still thirsty after all of that. 

The one issue?

You know, aside from having to go to the bathroom five hundred times a day… 

I get bored with drinking the same thing again and again and again. 

So I’ve been desperately trying to find alternatives! You might have seen my sparkling arnold palmer last week, which I am still super into drinking. 

However, since it’s summer, I want to celebrate the WATERMELON.

This watermelon lime agua fresca is only a handful of ingredients and it is SO refreshing. 

Made with fresh watermelon, it’s the easiest drink you could possibly make and you might just not share it with anyone else.

I am kind thankful that the Man isn’t a big watermelon fan… This entire pitcher was for me and only me!

this recipe’s must-haves

I like to use my Vitamix blender to whip this agua fresca up, but you can also use your food processor if that’s what you have readily available. Just make sure that it’s large because you are using a lot of watermelon that turns into a good amount of liquid.

You will also need a fine mesh strainer to strain out the solids to get a smooth drink as an end result.

here’s how to make watermelon lime agua fresca! 


Add the watermelon, lime juice, agave, and half the water to a large blender or food processor and blend until well combined. You want to make sure it’s smooth so the watermelon is completely broken down! 

There should be no chunks of watermelon left. 


Strain the mixture into a pitcher so you remove all the solids. Discard the solids, you won’t need those anymore!

Stir in the remaining water and chill until you are ready to serve it up. Be sure to serve it over ice. If you want to serve it boozy, check out my note in the recipe card below with instructions on amounts.

I like to use lime wheels, a wedge of watermelon, and a mint sprig as garnish because it’s so festive!

got questions?

Can I use honey or simple syrup?

Sure! I just like the way agave tastes, but both honey and simple syrup work well too for this recipe.

Does this last if you make it ahead of time?

I find that drinking this agua fresca is best when it’s fresh! You can also make it a handful of hours ahead of time if you like. If it separates as it sits, simply stir it all up vigorously before serving over ice.
