The ultimate summer sipper, this Juicy Watermelon Lemonade is sweet and refreshing – and only just slightly tart. The perfect summer beverage for cooling off on a hot day.
Watermelon Lemonade Recipe
Anyone else have a hard time resisting grabbing a fresh, ripe watermelon almost every time you hit up the grocery store or a farmer’s market in the summer?
For a special treat, instead of serving it sliced up, try making it into a juicy, sweet and refreshing watermelon lemonade. It’s perfect for serving at BBQs or summer parties, or just enjoying with the kids in the backyard. The vibrant color is so inviting and unlike a lot of lemonades, it’s actually a thirst-quencher thanks to the high water count of the watermelon.
I have some tips for picking out a ripe, juicy watermelon below but if you can’t find a ripe watermelon easily (or they are super overpriced where you live), you can use frozen watermelon chunks instead.
Tip: Skip the ice cubes and instead add some frozen watermelon chunks or freeze some extra watermelon juice in an ice cube tray to make frozen watermelon juice ice cubes to keep this watermelon lemonade icy cold without watering down it’s flavor.
Variations on this Watermelon Lemonade Recipe:
- add Sprite or use a fizzy lemonade like San Pellegrino for a pineapple lemonade punch
- add fruit syrups or chopped fruits for a fruity touch
- made a watermelon limeade by swapping out the lemon juice for lime juice
- add a teaspoon of grenadine or cherry syrup to the bottom of each glass
- add booze for a grown-ups only version (use plain, pineapple or coconut flavors of vodka, gin or rum)
- use pre-made lemonade (even pink lemonade)
- make into popsicles by pouring the mixture into a popsicle mold and freezing
- muddle mint leaves on the bottom of the pitcher or each glass for a mint-infused watermelon lemonade.
How to Pick a Ripe Watermelon
Here are some tips to help you pick the perfect sweet watermelon for this recipe:
- Look for the field spot. Look for a lighter spot where the watermelon rested in the field: it’s called a field spot. If the field spot is white, it’s unripe: if the spot is yellow, it’s ripe.
- Dense is good. Buy a watermelon that seems heavy for it’s size.
- Thump it lightly. The watermelon should sound slightly hollow when knocked lightly.
This watermelon lemonade should be stored in the fridge if not serving immediately. It will last about 4-5 days in the fridge.
For a sugar-free watermelon lemonade, skip the homemade simple syrup and make the watermelon lemonade with just water, lemon juice and blended watermelon. Sweeten with honey or your desired natural sweetener.
