How to Freeze Watermelon
Watermelon is made of a ton of water, so it takes it a long time to freeze. Depending on how frozen the watermelon is will determine the consistency of the slushie.
If the watermelon is frozen solid it will be more of a scoopable texture. If the watermelon has only been frozen for around 6hours it'll be thinner and a consistency you can slurp with a straw.
To start - I highly recommend getting a seedless watermelon. Picking out the seeds takes wayyy too much time!
I use a medium or average-sized watermelon to get 8 cups. Chop it up into cubes and aside in a bowl.
What method of freezing is totally up to you. You can freeze it on a baking sheet to prevent the watermelon from freezing into a block.
However, 8 cups is a lot of baking sheets of watermelon. So, I usually just toss it all into a large container.
If you let it feeze overnight or for 24hrs it will freeze into a block - but that's okay! Just take the watermelon out to defrost before you want to make the slushies.
This recipe is super simple:
- lime juice
- coconut water
You can easily change it up by swapping the coconut water for pineapple juice, mango juice or whatever tropical juice you want to try.
Trade the lime juice for lemon or grapefruit juice.
Garnish with a slice of citrus and fresh mint for a refreshing drink!

Recipe Tips and FAQs
It can! But you'll want to remove the seeds before freezing the watermelon chunks, and that takes a lot of work and time so seedless watermelons are definitely best.
If you freeze it overnight or for 24hrs it'll freeze solid and need to defrost for a bit before you use it in the recipe. The consistency will be thick and scoopable with a spoon. If you want a slushie that is slurpable with a straw try freezing the watermelon for just 6-8 hours.
