Watermelon juice is super easy to make at home - no juicer required! All you need is a blender, a watermelon, and a few kitchen tools, and you’ll be on your way to delicious summer cocktails, mocktails, and popsicles.
For the longest time I’d see watermelon juice in summer cocktails at my favorite restaurants and think “where do you get that?” I had no idea just how EASY it was to make! You don’t need a fancy juicer or much special equipment at all. And since watermelon is mostly juice, you don’t even waste much of the fruit after you blend it up.
What you’ll need:
- A watermelon
- A cutting board big enough to chop up your watermelon.
- A large, sharp knife to cut into your watermelon and cut it into pieces.
- A blender
- A fine mesh sieve that fits over, and mostly covers, a large bowl
What to do:
- Place your watermelon on the cutting board. Carefully cut it into large sections. Cut each section away from the watermelon rind. Dispose of the rind and cut the watermelon flesh into 2 -3 inch pieces. (These are getting blended up, so don’t worry about them being symmetrical or looking nice!)
- Place 3-4 cups of diced watermelon in a blender, cover, and purée until smooth.
- Pour the pureed watermelon through the fine mesh sieve into the large bowl. Use a spoon or spatula to move the watermelon pulp around in the sieve, making sure all the juice goes into the bowl.
- Dispose of the pulp leftover in the sieve.
- Repeat steps 2-4 until you have all the watermelon juice you want!
- Pour the juice from the bowl into a pitcher and chill until ready to use.
FAQs About Watermelon Juice
An entire "personal" sized watermelon will make aprox 64 oz of juice, but you can make as much or as little juice as you want. Feel free to make a small amount - and save yourself some time - by using the precut chunks of watermelon found in most grocery stores.
The most popular brand has cherry juice added to it, which significantly alters the taste of the juice. So don’t buy bottled watermelon juice at the store without checking the label. Any time I’ve bought watermelon juice at the store, I’ve regretted the taste and wished I’d just made some myself.
The juice will start separating if not used within a couple hours. If you leave it sit in the refrigerator overnight, there’s a good chance it’ll separate into 3 distinct layers. This does NOT impact its taste and does NOT mean it’s gone bad. Simply stir or shake the juice to mix it back up.
It will keep in the refrigerator for 4-5 days.
