(This recipe for Watermelon Margaritas was originally published in August 2010, but was updated with new photos in 2019).

Can I just say how happy I am that it’s Friday? I’m looking forward to an absolutely fabulous weekend that will involve hanging out with some of my favorite friends, having brunch with my sister and bro-in-law, and hopefully spending some quality time at the pool (yes! my new apartment building has a pool. Swooon!) OK, OK and I’ll also be doing lots of work on finishing all my unpacking, so I can show you a bit more of my apartment. Next week, I promise!

Now, summer Fridays call for margaritas, yes? I was going to throw this little recipe in with my post about what I had for dinner the other night. But then I determined that it needed its own post. Because it’s easy, delicious, and absolutely necessary for all of you to make. Who doesn’t need more margaritas in their life? Also, the drink section of WANM has been sadly looking a little empty. It is now my goal in life to fill it up.

Seriously, one of my goals for my move is: MAKE MORE COCKTAILS. I’m not even kidding. I see tons and tons of cocktail recipes, but always find myself mixing Absolut Boston (or vanilla!) and sodas. Or just sipping on a glass of red wine. But it’s summer and summer calls for fresh fruit in fun drinks. Especially in margarita form.


First, I recommend you prepare the glasses. This is obviously optional and if you’re in a hurry or not a fan of salt-rimmed margaritas, you can skip it. Or you can use coarse sugar instead. I love a good salty rimmed margarita! I rubbed the rims with a little bit of lime and then put the glasses on a plate with coarse salt. Then I popped the glasses in the freezer so they could chill while I was preparing the watermelon margaritas.

I recommend you keep your watermelon cubes nice and chilled before you blend the margaritas. I just keep mine in my fridge, but if I wanted a true frozen watermelon margarita, I’d freeze them. Pop the watermelon in the blender with the lime juice, tequila, and Triple Sec, and blend until combined. Add ice and blend again, for about a minute, until smooth.

Pour into the chilled glasses and garnish with a little lime wedge.

Take a sip and rejoice in the fact that we still have plenty of summer left to enjoy.

I had one of these suckers waiting for Chris when he got home from work. Which made him happy and me girlfriend of the year. Except now, every day I don’t have a drink waiting for him, it’s like “remember that time you had a watermelon margarita waiting for me when I got home from work?” Le sigh.

This isn’t really a frozen margarita, but because there’s ice involved, it does have an icy froth to it, which I absolutely love. Like I mentioned, just freeze your cubed watermelon if you want this to qualify as a true frozen margarita.

This watermelon margarita would probably run you at least $12 at any bar here in Boston. But making it at home cost less than $1. And like I said, it’s incredibly simple! And super refreshing and delicious… The watermelon isn’t overly sweet, and tasted totally natural (you can add sugar in if you want it sweeter… You can also add more tequila in to make it more boozy).

Now if you excuse me, I’m off to the pool with one of these in hand. OK, I’m totally lying. I’m off to finish a ton of work, so I can have some fun this weekend. But I might take a quick pool break. And a margarita may just be in order later tonight.

What are you up to this weekend? Will it involve any watermelon margaritas? 🙂

  6. Kelly says:

    I love making watermelon margaritas. They are fantastic this time of year when the watermelon is so juicy and sweet. I made them a year ago and really should make them again. No margaritas this weekend for me, that I know about, but it should still be relaxing.
