Watermelon Lemonade is sweet, tart, and made with the simplest ingredients! Made with just watermelon, lemonade, and a splash of sparkling water, this is a budget friendly recipe that’s delightfully easy to make a pitcher of.

By the looks of HomeGoods and Target right now, you’d think we were in the thick of spooky season! As much as I’d also love to watch scary movies and fully pretend it’s autumn already, the weather outside won’t let me forget that it’s still, in fact, summer. The leaves are all still vibrantly green and the thermostat is relentless – so beat that heat with a glass of homemade Watermelon Lemonade!

Essentially, this is just a pink lemonade recipe that has an extra touch of fruity flavor from the fresh watermelon. It’s just as pretty to look at as it is tasty! Just make sure you choose a brand of lemonade you like, that way you know you’ll like the final product. If you really feel like showing off, you can make the lemonade from scratch… But I’ve found that using the store bought stuff always yields just as good results, and my hands aren’t aching from squeezing lemons.

Before it’s officially pumpkin spice latte season and too cold to lay out by the pool, chop up some watermelon and enjoy every sweet, tart, and cool sip of this easy to make Watermelon Lemonade! While you can keep it super simple with just the watermelon and lemonade, I also like to toss in some sparkling water for a touch of bubbles. Isn’t everything a little more fun when it sparkles?

Ingredients You’ll Need

  • Watermelon – You’ll need about 6 cups of cubed watermelon. Make sure you get a seedless one to keep things easy!
  • Lemonade – You can use diet or regular lemonade, both work well. For the best results, try to use a brand you already know you like.
  • Sparkling Water – This is optional, but I like some bubbles in my lemonade!
  • Ice

How to Make Watermelon Lemonade

For more detailed instructions, scroll to the bottom of this post.

Blend. Blend the watermelon until it’s smooth. You can strain it if you’d like, but you don’t need to if you’d prefer to have some pulp.

Pour. Pour the watermelon juice, lemonade, ice, and sparkling water into a pitcher.

Lemon wedges and mint sprigs are placed around several glasses of watermelon lemonade.

Common Questions

Can I make Watermelon Lemonade boozy? Yes, you sure can! If you’re adding liquor to the whole pitcher, I’d recommend pouring in about 5-7 ounces of vodka to a boozy kick. Taste test it before adding in any more.

Can I sweeten Watermelon Lemonade? I’d personally avoid adding any sugar or simple syrup to this already sweet recipe. The natural sweetness of the watermelon and the sugar in the lemonade will lend a good amount of sweetness to every sip!
