I made this drink on a whim last July because my watermelon was about to go bad, and I haven’t bought a bag of ice for plain water since.
It’s watermelon, mint, and lime blended into something that tastes like it should cost $9 at a beach bar. It doesn’t. It costs about $4 to make a whole pitcher.
I brought a jug of this to a backyard barbecue last summer and watched three different people ask me what was “actually” in it. One guy assumed there was alcohol. There wasn’t. It’s just that good.
Here’s exactly how I make it.
What You’ll Need
| Ingredient | Amount |
|---|---|
| Seedless watermelon, cubed | 6 cups |
| Fresh mint leaves | 1/3 cup, packed |
| Fresh lime juice | 1/4 cup (about 3 limes) |
| Cold water | 1 cup |
| Honey or simple syrup | 2 to 3 tablespoons |
| Ice | For serving |
| Extra mint sprigs and lime slices | For garnish |
That’s it. Seven ingredients, and two of them are ice and garnish.
Tools You’ll Need
- A blender
- A fine mesh strainer (optional, but I use it every time)
- A large pitcher
- A citrus juicer, or just your hands
How to Make It
- Cube your watermelon. Cut off the rind and slice the flesh into rough chunks. You don’t need to be neat about it.
- Blend it up. Add the watermelon, mint leaves, lime juice, water, and honey to your blender. Blend until completely smooth, about 30 seconds.
- Strain it. Pour the mixture through a fine mesh strainer into your pitcher, pressing with a spoon to get all the liquid out. This step is optional, but it removes the pulp and makes the drink feel more like something from a fancy resort.
- Taste and adjust. Depending on how sweet your watermelon is, you might want more honey or a little extra lime. Every watermelon is different.
- Chill it. Pop the pitcher in the fridge for at least 30 minutes. It tastes even better cold, and honestly, it tastes better the next day too.
- Serve. Pour over ice, and garnish with a mint sprig and a lime wheel.
Total time, including chilling? About 45 minutes, and most of that is just waiting.
Pro Tips
- Use the ripest watermelon you can find. An underripe one makes a bland, watery drink. Look for one that feels heavy for its size, with a creamy yellow spot where it sat on the ground.
- Don’t skip the strain unless you like pulp. I tried skipping it once to save time. It was fine, but noticeably grittier. Your call.
- Bruise the mint before blending. Gently rub the leaves between your palms first. It releases more of the oil, and the mint flavor comes through so much stronger.
- Add the honey while the watermelon is still slightly warm from the counter, if you’re using raw honey. It dissolves faster and blends smoother than straight from the fridge.
- Make a big batch. This drink disappears fast, and doubling the recipe takes zero extra effort since it’s all one blender step.
Substitutions and Variations
- No honey? Agave, maple syrup, or plain white sugar all work.
- Want it sparkling? Swap the cold water for club soda or sparkling water, added right before serving so it stays fizzy.
- Feeling fancy? A splash of white rum or tequila turns this into a full cocktail. Add it directly to each glass rather than the whole pitcher, so people can opt in or out.
- No mint on hand? Basil actually works surprisingly well here. It gives a slightly peppery twist that a lot of people end up preferring.
- Different melon? Cantaloupe or honeydew can sub in for watermelon, though you’ll want to cut the water down slightly since they’re less juicy.
Make Ahead Tips
You can blend this up to 2 days ahead and store it in the fridge in a sealed pitcher.
Give it a good stir before serving since the pulp (if you didn’t strain) tends to settle at the bottom.
I actually think it tastes better on day two. The mint has more time to infuse into the watermelon.

Diet notes: This is naturally vegan, gluten-free, and dairy-free. Swap the honey for maple syrup or agave to make it fully vegan if that matters to you.
Pairing suggestions: This drink goes really well next to grilled shrimp skewers, a light Caprese salad, or really any backyard barbecue food. It cuts through rich or smoky flavors nicely.
Time-saving tip: Buy pre-cubed watermelon from the store. It shaves off almost 10 minutes and honestly tastes exactly the same once it’s blended.
Leftovers and Storage
Store leftovers in a sealed pitcher or mason jars in the fridge for up to 3 days.
I don’t recommend freezing the blended mixture. It separates when it thaws and the texture gets weird.
If you do have extra watermelon-mint puree before you add the water, that part freezes fine in ice cube trays. Drop a few frozen cubes into lemonade or sparkling water later for an easy flavor boost.
FAQ
Can I make this without a blender? You can muddle the watermelon and mint together and press it through a strainer, but it takes longer and won’t be quite as smooth. A blender genuinely makes this so much easier.
Is this the same as watermelon juice? Close, but not quite. This has mint and lime mixed in, which gives it more of a cocktail-style flavor rather than straight juice.
Can kids drink this? Yes, without the optional rum or tequila, this is completely kid-friendly and a great way to sneak in extra hydration on hot days.
Why did my drink turn out foamy? Blending on too high a speed for too long can whip in extra air. Blend just until smooth, not longer.
Can I use frozen watermelon instead of fresh? Yes, and it actually works well if you want a slushier, more frozen drink. Just cut back on the ice when serving since the fruit itself is already cold.
Wrapping Up
This is one of those recipes that looks way more impressive than the effort it actually takes.
Seven ingredients, one blender, and you’ve got something that tastes like summer vacation in a glass.
Make a pitcher this weekend, and let me know in the comments how it turned out, or if you tried one of the variations. I’d love to hear if the basil swap won anyone over.
