Around our home, we are BIG lemonade fans. I’m a big watermelon fan as well.  So what better than a combination of two of my favorite things?

I love the blend of sweet and tart with just a bit of fizzy zip; this really is a fantastic drink! 

I especially love how easily this recipe comes together. It’s got all the makings of a fancy drink, but is quick and easy to make! You’ll love the fresh and fizzy flavor of this easy watermelon pink lemonade.

Watermelon lemonade ingredients?

Just as the name implies, this fresh watermelon lemonade recipe is made with simple ingredients: mostly watermelon and lemonade, with a bit of sparkling water or lemon lime soda for a zippy kick! 

Here’s what you’ll need to get started: 

  • Sugar – in this recipe, we start by making a simple lemonade syrup
  • Water – to make the lemonade syrup, you’ll combine sugar, water, and lemon juice over the stovetop. 
  • Fresh lemon juice – For the best results, use fresh lemons, not store bought juice.
  • Watermelon juice – sometimes you end up with a delicious watermelon that’s just too big to finish fast! That’s where this recipe is pure gold — puree part of the watermelon, strain it, and use the juice for delightful watermelon lemonade! 
  • Sparkling water (or lemon-lime soda) – I’ve always been a fan of using sparkling water instead of regular water in my lemonade. Try it! I’m sure you’ll love it too!

How long does watermelon lemonade last?

Once you’ve combined the watermelon juice, lemonade syrup, and sparkling water, you have about 2-3 days of peak drinking time (if it lasts that long!) when stored in the refrigerator. Keep in mind the sparkling water can go flat pretty quickly if not stored in an airtight container.

Can you freeze watermelon lemonade?

I don’t recommend freezing the mixed watermelon lemonade because the sparkling water will go flat and it’s much easier to thaw the frozen components in room temperature water. You can certainly freeze the individual components! See below for suggestions. 

Watermelon juice can be frozen in ice cube trays or in a solid block. You’ll want to strain the juice before freezing it. Be sure to store it in an airtight container once it’s frozen so it will stay fresh. You can freeze watermelon juice for up to 2 months when stored correctly. 

Lemonade syrup is great frozen! You can freeze it for 2-3 months in an airtight container or bag, or it keeps well in the fridge for 2-3 weeks. 

To make frozen watermelon lemonade, a slushy and cold twist on this recipe, freeze the correct amount of watermelon juice and lemonade syrup in ice cube trays. When the juice and syrup are frozen, pop them out into a blender, add the correct amount of sparkling water, and pulse until a slush forms!

Who invented lemonade?

Lemon-based drinks have been around since the ancient Egyptians, who combined lemon juice with honey to make a sweetened lemonade like wine. 

In France during the 1600’s, lemonade was bottled and sold. It’s now a popular drink throughout geographic regions and is served both carbonated and still (depending on where you are!).

Is lemonade a juice?

Not exactly. Lemonade is made using lemon juice, additional sugar, and sparkling or still water. Because there is so much added sugar, it’s considered more of a sweetened drink than a juice.

Does lemonade have caffeine?

No, lemonade does not have caffeine! Caffeine is not naturally occurring in either lemons or watermelons. 

Is watermelon lemonade good for you?

While there are nutrients to be found in watermelon lemonade, it’s a heavily sweetened beverage and therefore not a healthy food. As always, moderation is key. If you’re someone who needs to watch their added sugar intake, this probably isn’t the drink for you.

Is watermelon lemonade gluten free?

Yes! Watermelon, lemon juice, sugar, and sparkling water are all naturally gluten free, so this easy watermelon lemonade should be as well! As always, be sure to check your labels to confirm. 

Can dogs drink lemonade?

Lemonade is high in citric acid AND sugar — neither of which are good for your dog, cat, or any other pet! Please don’t give your pup lemonade, no matter how much you might enjoy it yourself.
