Watermelon Soda is a 5-minute homemade drink made with fresh watermelon, lime juice, and sparkling water — naturally sweet, fizzy, and the most refreshing way to cool down this summer!
Once summer hits I want all the cold and refreshing drinks I can get my hands on. I mean, after some time outside, i am all for a cold glass of water. But I really like to switch it up no and then.
And using fresh, juicy watermelon makes for the most refreshing, sweet, and fruity drink!

Ingredients You’ll Need
A ripe watermelon makes all the difference here. Look for one that feels heavy for its size, has a dull (not shiny) rind, and has a creamy yellow spot where it sat on the ground while ripening. The sweeter your watermelon, the less sugar you’ll need to add.
- Fresh Watermelon – seedless is best for this recipe
- Lime Juice
- Water
- Sugar
- Sparkling Water – I used sparkling lime flavored water
This really is just a few simple ingredients to make a homemade soda that you will come back to over and over again. And you really can play with the recipe. I use lime sparkling water, but you can use plain, berry, or another fruit combination and it will be delicious!

How To Make Watermelon Soda
The blender does almost all of the work, so it is ready in no time! Aside from actually chopping the watermelon, but if you buy the already peeled stuff, you can be enjoying a glass in 5 minutes.
- Add the diced watermelon, lime juice, water, and sugar to the food processor or blender and blend until it is completely smooth.
- Pour the mixture through a strainer to get rid of the pulp and any chunks,
- In a large pitcher combine the sparkling water with the watermelon juice and mix until combined.
- To serve pour over glasses filled with ice.

Can You Make Ahead
Yes! If you want to make this ahead, stop before adding the sparkling water. Make just the watermelon-lime base and store it in an airtight container in the fridge for up to 2-3 days. Add the sparkling water right before serving, since it loses its fizz fast once mixed in. You can also mix individual glasses to order, about equal parts watermelon base and sparkling water, if you don’t want to make a whole pitcher at once.
This homemade soda is so easy to make and will definitely rethink letting your kids (or yourself) have soda in your life. It is full of fresh fruit and delicious. Skip all the chemicals and junk in the canned stuff from the store and make your own watermelon soda on repeat all summer long!

No, if you want yours less sweet and a little tart you can absolutely skip it! If you want it to taste more like the store bought kind, you will want to add it. It will also depend on your watermelon, some are definitely more sweet than others.
You really can use anything fizzy for this step. I used lime flavored sparkling water to give it more flavor, but you could use the unflavored kind, club soda, or really and flavor that pairs with watermelon and lime.
Because of the carbonation this isn’t a drink that will store well. If you don’t think you will drink it all at one time, you could add the sparkling water to the top of each glass. Then store leftovers in the fridge for a couple days, adding fresh sparkling water each time.
Absolutely! If you want to make this a grown up cocktail you definitely can. Vodka or Rum would be great additions.
Yes! Frozen watermelon works great for the blended base, and it makes the soda extra cold and slushy — perfect for a hot day. Let it thaw for about 10 minutes before blending so your blender doesn’t have to work as hard.
