On a hot summer day, there's nothing like this Watermelon Mint Lemonade! It's refreshing, delicious, easy and make-ahead.
A couple of weeks ago, I took my granddaughter Annie, to Chick-fil-A for lunch. I was scanning the menu and my eyes stopped at Watermelon Mint Lemonade. Maybe it's been on the menu for a long time but, not being a frequent fast-food consumer, it was the first time I'd noticed it.
"Annie, would you like to try the Watermelon Mint Lemonade?" I thought she might think it was a strange combination, but she didn't hesitate for a minute. "Sure!" she replied.

When our food arrived I was curious and asked if I could try a sip of her drink. Oh my goodness! I loved it and so did Annie. I knew right away I was going to have to figure out how to make this wonderfully refreshing drink.
It seems we're all in a hurry these days, so I decided to start with a can of frozen lemonade. That made things simple, as all I had to play around with was the watermelon and mint. A couple days later, I bought a beautiful seedless watermelon and a big bunch of mint and was ready to roll.
How to add lots of watermelon and mint flavor?
It was surprising how much watermelon it took to actually arrive with a distinct watermelon flavor. I started with around 4 cups of diced watermelon and was finally happy with the recipe at 8 cups (about ½ of a medium size seedless watermelon).
I pureed the watermelon in the blender along with some of the frozen lemonade. Watermelon drinks can be a bit "pulpy" though, which is great for a smoothie or slushie, but I didn't want that for my lemonade. Straining the pureed mixture with a fine mesh strainer took care of that problem easily.

Along with the watermelon, the Chick-fil-A lemonade also had a distinct mint flavor. I decided to achieve that with muddling and steeping. What's muddling? It's simply bruising herb leaves in order to release the oils which contain their wonderful flavor. I don't have a muddler so I used the blunt end of a large wooded spoon to crush or "bruise" my mint. It worked like a charm!

Allowing the muddled mint to steep in the lemonade for about 15 minutes was all it took to get lots of bright, fresh mint flavor. The muddled mint was then discarded and when I served my watermelon mint lemonade, I used beautiful fresh mint sprigs for garnish along with pretty yellow lemon slices. I couldn't wait to let Annie try it. I let her be the official "taste-tester" and the smile on her face after the first sip was a huge thumbs up!

Make it ahead and freeze
In the process of getting this recipe "just right" I made several batches and had quite a "stash". I decided to try freezing it so I could serve it for the 4th of July. I used a large Rubbermaid container and just pulled it out a few hours before our guests arrived. It tasted like it was freshly made!
Is the summer heat is getting to you? It's been in the mid 90's here in Carolina for quite a string of days now. Just looking at these pictures make me want another a batch of this Watermelon Mint Lemonade. Try it! I think you'll find too, that it's the perfect way to beat the heat!

My Market doesn't sell frozen lemonade concentrate so I froze My fav Matt's bottled lemonade in silicon cubes. I used one medium watermelon and one bottle of lemonade. I did not add sugar. I made the mistake of freezing both the watermelon and lemonade and that does not work at all. Freezing the lemonade in cubes and fresh watermelon worked best for me. This recipe is Delicious! My husband LOVEs it! Its so refreshing! I would maybe add some fresh strawberry too next time! Summer vibes for your bridal and baby showers with this beverage is a must have!
Thanks for the great review, Lisa, and for sharing your substitution ideas - freezing your own lemonade cubes is a clever fix! So glad to hear how well this recipe turned out for you and we'd love to hear your thoughts if you try adding fresh strawberries. We appreciate you taking the time to let us know how much you and your husband enjoyed this recipe!
Did you use peppermint or spearmint? I have only spearmint in my yard.
Hi Ems, I use spearmint.
I'm so happy that you and Annie had that lunch date because now we get to enjoy this pretty summer dirnk.
Goodness, that looks refreshing, Chris! I think you did a great job of replicating a delicious and perfect-for-summer beverage!
Such a nice summery drink! And it's gorgeous -- as are the pictures. This is a winner -- thanks.
So perfectly refreshing and beautiful! We are still waiting for the big Summer heat here. It's been nice enough, but we have yet to string together a bunch of hot days in a row. I'm sure they're coming, so I'll be prepared with this refresher 🙂
That looks like the best 116 calories I've ever had 🙂 Our temps are hitting 3 digits this week, so you are right on time with this refreshing lemonade, thanks Chris!
I'm hanging out with my sisters up in Northern Minnesota and a pitcher of this fabulous lemonade would be welcomed on the dock! What a wonderful, refreshing summer beverage!!
You girls and your lemonades!!:) Porch swings..lattice pies..lemonades♥
Lovely posts ladies.And Scott:)
Wow! does this watermelon mint lemonade refreshing , love the color. Annie sounds like a wonderful taste terster. My grandsons love chick-fill-a too.
Yes, it has been very hot here, too. Watermelon and lemonade weather, and you have combined them both! I declare that you can copy anything you taste, and make it even better! It is beautiful, and I can almost smell the mint. and now that your grandchildren are living so much closer, I know you will be turning them into excellent cooks!
I have the watermelon and mint but only fresh lemons on hand. I will try it with fresh lemons and add more sugar.
Hi Diane,
I would just go with a classic lemonade recipe and then add the watermelon and mint as in this recipe. Enjoy!!!!
Wow -this looks sooooooo refreshing! Absolutely gorgeous color and the flavors are perfect. I recently enjoyed a mint and watermelon salad so I know I'm going to love this! Thanks for the link love - sharing, pinning and wishing I had a glass right now! Stay cool 🙂
Sounds like you and Annie had a nice lunch together Chris. This lemonade sounds absolutely refreshing and PERFECT for summer! I love the addition of the mint!
