Ingredients You’ll Need
You only need a handful of simple ingredients to bring this Watermelon Lemonade to life, and each one plays an essential role in the final flavor. Some provide sweetness, others add a punch of citrus, but together, they promise a pitcher full of summer joy!
- Watermelon: Use 5 to 6 cups of seedless watermelon, cut into cubes; it’s the sweet, juicy heart of this drink.
- Ice Cold Water: Two cups of cold water help turn your watermelon into a perfectly drinkable lemonade—super chill is key!
- Granulated Sugar: One third of a cup to dial up sweetness and balance the tang of lemons and limes.
- Lemon Juice: About 4 large lemons give you half a cup of bold, tart juice—absolutely essential for that classic lemonade kick.
- Lime Juice: Two tablespoons (about 1 large lime) add a subtle, lively zing that pairs beautifully with watermelon.
- Agave Nectar (Optional): For a natural, mellow sweetness, add two tablespoons; honey or maple syrup can swap in, too.
- Garnishes: Fresh mint leaves, watermelon, lemon, or lime slices make every glass look and taste extra special.
How to Make Watermelon Lemonade
Step 1: Blend the Watermelon
Begin by piling your cubed watermelon, ice cold water, and granulated sugar into your blender. This is when the kitchen starts to smell like summer! Blitz everything until it’s silky smooth; if your blender has a smoothie setting, go ahead and use it for that extra-creamy finish.
Step 2: Strain the Juice
Set a fine mesh strainer over a large pitcher or bowl, and carefully pour in your blended watermelon mixture. Use the back of a spoon to press the juice through—this step removes pulp, giving your Watermelon Lemonade that signature light, lovely texture.
Step 3: Add Citrus and Sweetener
Now stir in the fresh lemon juice, lime juice, and agave (if you’re using it). Give it a good mix so everything dissolves and marries into a sweet-tart symphony. At this point, take a taste—feel free to adjust the sweetness with more sugar, agave, or honey if you like it a bit sweeter.
Step 4: Serve Over Ice
Pour your Watermelon Lemonade over tall glasses filled with ice. Top each glass with a wedge of watermelon, a lemon or lime wheel, and a few sprigs of fresh mint if you have them. Get ready for some seriously happy sips!
How to Serve Watermelon Lemonade

Garnishes
Nothing says celebration like a colorful garnish! Add a slice of juicy watermelon on the rim, a twist of lemon or lime, and a sprig of mint. Not only do these look festive, but the extra aromas from the herbs and citrus make every sip more vibrant.
Side Dishes
This Watermelon Lemonade is a sunny sidekick for all kinds of summer fare. Think crunchy salads, chips with guacamole, grilled corn, or just about anything off the BBQ—its bold flavor holds its own and keeps your palate refreshed.
Creative Ways to Present
For parties, serve Watermelon Lemonade in mason jars with paper straws, or pour it into a big dispenser for easy refills. For a grown-up twist, you can add a splash of sparkling water, or even a touch of vodka or gin (just label those adult batches). Kids will love it as popsicles—just pour into molds and freeze overnight.
Make Ahead and Storage
Storing Leftovers
Have extra Watermelon Lemonade? Pour it into a covered pitcher and keep it chilled in the fridge. It will stay fresh and fabulous for up to three days—just give it a quick stir before serving, as flavors can settle.
Freezing
If you made a big batch, you’re in luck! You can freeze leftovers into ice cube trays, then use those cubes to chill your next pitcher without watering it down or blend them for a slushy treat whenever you get a craving.
Reheating
This one’s best served cold, but if your lemonade gets too icy from being in the fridge, just give it five minutes at room temperature and a gentle stir—it’ll be ready to serve again, fresh and delicious as ever.
FAQs
Can I make Watermelon Lemonade ahead of time?
Absolutely! Whip up a batch the night before your get-together and store it in the fridge. Just stir well before pouring, and add ice and garnishes right before serving for the prettiest, freshest presentation.
Do I have to strain the watermelon juice?
While straining is optional, it gives your Watermelon Lemonade a smoother, lighter texture. If you don’t mind pulp—or even love a bit of extra fiber—feel free to skip that step!
What’s the best sweetener to use?
Granulated sugar is classic, but agave nectar, honey, or maple syrup are all wonderful. Just taste as you go—adjust sweetness to suit your crowd or your mood!
How do I make this recipe sugar free?
Try swapping out the sugar and agave for your favorite zero-calorie sweetener. Stevia or monk fruit both blend well with the fresh fruit flavors and keep things light.
Can I use a different fruit instead of watermelon?
Feel adventurous! Cantaloupe, honeydew, or even strawberries make fun variations—just be sure to keep those bright citrus flavors front and center so it still tastes like lemonade.
