Looking for a refreshing summer drink? Watermelon Mint Lemonade is full of fresh flavor and is the perfect way to cool off on hot summer days.
It’s hot outside, but I h ave a solution. This is one of the first drinks I learned to make from scratch back in the early days of this blog when I lived in Bangkok, Thailand and every day was a warm, sunny day. I can tell you from experience that there’s a lot to love here.
🍉 What you’ll love
- Hydrating – Watermelons are naturally hydrating, so you’ll love that boost.
- Adjust to taste – Watermelons are naturally sweet, so you can adjust the amount of sugar you add. Adjust your lemon too, for a more or less tart flavor.
- Make Ahead – This can be made up to 3 days ahead, stored in the fridge, and poured whenever you’re thirsty.
FAQs
Can it be made ahead?
Yes! Make Watermelon Mint Lemonade up to 24 hours in advance. Store it in a pitcher in the fridge and stir before pouring.
Can I use honey or another sweetener instead of sugar?
Yes. Play around with using honey, agave syrup, or maple syrup for the sugar. You can also try skipping added sweetners if your watermelon is at peek season and is naturally sweet enough.
Want to make it a cocktail?
For a boozy twist, pour a shot of vodka, rum, or tequila into your glass before pouring in the lemonade. Or blend it with ice for a frozen cocktail version!
Can I freeze leftovers?
Yes! It freezes well and can even be turned into watermelon frose.

Watermelon Mint Lemonade
Equipment
- Saucepan
- Sieve or Colander
- Blender
- Pitcher
Ingredients
- ½ cup granulated sugar
- 10 cups seedless watermelon, cubed in 1-inch pieces
- 1 cup fresh-squeezed lemon juice
- ½ cup loosely packed mint leaves
- lemon slices, for serving
- fresh mint sprigs, for serving
Instructions
- Make a simple syrup by combining 1/2 cup sugar and 1/2 cup water in a small pan over medium-high heat. Heat the liquid just until the sugar is complete dissolved, 5-6 minutes. Set the simple syrup aside to cool.
- Pulse the watermelon in a blender until smooth. (You may need to do this in 2 batches.) Strain the pureed watermelon through a fine mesh collander into a large bowl. Discard the pulp and rinse the blender container out with water.
- Return the watermelon liquid to the blender. Add the lemon juice and mint and blend until the mint is very finely chopped. Transfer the Watermelon Mint Lemonade to a juice pitcher. Slowly adjust for your desired sweetness by adding simple syrup to the lemonade. (I found that I needed only about half of the simple syrup, but depending on the sweetness of your watermelon, this may vary.)
- Chill until serving. Serve over ice, with lemon slices and fresh mint as a garnish.

Try using the Spice blend Tajin on Watermelon, cantaloupe, tomatoes it is amazing
Oh yum! That sounds so good! Will try it
Hi this looks very refreshing and tasty 🙂 .. just wondering what sort of mint would be most suitable… spearmint? Peppermint ? Or just regular plain mint ?
Thanks
That’s a great question, Brandon. I had regular mint (not specified as spearmint or peppermint) growing in my garden this year and almost always just used that. The other varieties would be great too, especially if you have a preference for those mint flavors!
Never thought of adding lemon juice to watermelon. Tried it & loved by all in the family
So glad you liked it! It really does bring out both flavors, right? It’s a combination I had never tried before either, but now I use it all the time. I even make a fruit salad with cubed watermelon and a little lemon juice and mint on top.
Yummm!!! This looks so good, even better than celebrity gossip 🙂 My pregnant summer has me loving all things watermelon, so I can’t wait to try this…although I’ll have to wait a bit to hit the gin.
sounds awesome – we dont have seedless melons here but maybe ill make some next weekend at my parents house… sounds delicious!

We don’t have seedless watermelons either, which definitely added an extra step to making these. I saved the really seedy peices of the melon and we just ate those. 😉
Test
Wow, this looks so refreshing and delicious! Watermelon is definitely one of my favorite summer foods and I love discovering new ways to enjoy it, so thank you! Cheers!
Me too, Mercedes – I can never get enough watermelon this time of year!
Wow. Those look so refreshing. I think mint makes anything cooler to the palate. I am posting a watermelon popsicle later this week too. (I am a sucker for entertainment gossip—don’t judge! I can’t believe she stayed with him this long!) 🙂
Can’t wait to see your watermelon popsicle, Debra. I love how many variations can stem from that simple, refreshing treat!
