Watermelon Juice

Yesterday evening, I made a pitcher of sweet, refreshing watermelon juice to keep me hydrated while I packed up my house.

It took me back to San Pedro Island, where I sipped watermelon juice under the shade of a palm tree earlier this month.

We walked down the beach to Estel’s, where we enjoyed a leisurely, traditional Belizean breakfast—scrambled eggs, refried black beans and fry jacks, complete with watermelon juice. It was a good start to a very good day.

How to Make Watermelon Juice

Watermelon juice couldn’t be easier to extract. You don’t need a fancy-schmancy juicer, just a blender.

Scoop the watermelon into the blender, blend for about thirty seconds, and ta da! You’ve made watermelon juice.

Taste your juice straight from the blender. If you like it as is, you don’t need to strain it.

If your watermelon had seeds in it, or you want your juice to be less pulpy, pour it through a fine-mesh sieve into a pitcher. Easy!

If your juice separates as it sits, give it a little whirl with a spoon. If you’re thinking about adding a splash of tequila or white rum… I can verify that that is indeed a good idea.

Watermelon Juice Nutrition

As you would expect, watermelon juice is good for you. It’s high in vitamin A, vitamin C and potassium. It’s about 92% water, so it’s plenty hydrating, too (nutrition source).

I thought my juice was perfectly sweet without any added sugar, but I added a squeeze of lime juice for that extra zing.

Refreshing, naturally sweet watermelon juice couldn’t be easier to make in a blender. Yield will vary based on the size of your watermelon, but my 6.5-pound watermelon yielded about 5 cups of juice. 

Ingredients

  • 1 small sweet watermelon (a 6 pounder will do)
  • 1 small lime, juiced (optional)

Instructions

  1. Slice the watermelon in half. Using a big spoon, scoop chunks of sweet watermelon into the blender. Discard the rind.
  2. Blend the watermelon until it is totally pulverized. This shouldn’t take more than a minute. For extra flavor, squeeze the juice of one small lime into the blender and blend for a few seconds.
  3. If your watermelon is notably pulpy or seeded, pour the mixture through a fine mesh strainer into a pitcher. If not, you can pour it directly into glasses filled with ice. Watermelon juice will keep in the refrigerator, covered, for up to 4 days. The juice will separate over time; stir it with a spoon to recombine.

Notes

Watermelon selection: Your juice will only be as good as your watermelon, so find a good one at a farmer’s market or health store. Look for a watermelon that is heavy for its size, round, dark and dull (versus shiny) with a yellow field spot.

Change it up: You can make cantaloupe juice using the same method! You can also turn your watermelon juice into popsicles by pouring the juice into a popsicle mold and freezing until solid. You might also like my melon cocktails—try the watermelon cucumber cooler or cantaloupe fiesta cocktail.

    I love juice recipes that don’t use any processed sugar, very yummy and healthy as well.

  2. Kd

    Thanks Kate for this recipe!. I came across it yesterday and i already had frozen watermelon at home. Couldn’t wait to do this. It was very refreshing, quick and simple to do. Now i would be buying some more watermelon before the end of the season.

    1. Kate

      Thanks, KD! I never thought to make the juice with frozen watermelon. Glad you liked it!

  3. Kd

    This is a tried recipe and taste really good

    Hi,
    Your recipe sounds very refreshing and am going to try it. Can you please explain why do we need to add lime juice. Can this be optional?

    1. Kate

      Hi! The lime juice is optional. I just felt like the lime enhanced the watermelon flavor, but you can skip it!

  7. Taunya

    Great recipe! I like that you removed the sugar and added lime. I learned how to make watermelon juice in a small Belize village where I have just opened a small restaurant and sugar is always added. I think our guests will like it better this way. Especially based on how sweet watmelon is here in Belize. Thanks!!

  8. Doris

    GREAT IDEA..YOU CAN EVEN USE THOSE WITH SEEDS..JUST USE A POTATO MASHER OR USE YOUR HANDS OVER A STRAINER,,YOU DON’T NEED A BLENDER WITH THIS METHOD…LOVE, MOMMA DORIS..KEEP SENDING GREAT RECIPES..THANK YOU AND GOD BLESS…

    1. Kate

      Sorry, I don’t think so.

  14. Rebecca

    wonder how it would come out if you poured in ice cube tray froze and then blend….

    1. Kate

      Ooh, let me know if you try that, Rebecca.

  15. Chris

    Just made this for my daughter who is a cheerleader. It drives me crazy that she wants a Gatorade at all her competitions. I am thinking this could be a perfect replacement! :-)

    Thanks for sharing.

    1. Kate

      I hope so, Chris! That’s a great idea.

  16. JAY

    This is my first time making a watermelon juice and this is the perfect recipe! I bet leaving the watermelon as it is brings out a sweeter and more refreshing juice. Thanks!

    1. Kate

      Thanks, Jay!

  17. Edward

    3 pitchers of watermelon juice later
    a) straight as your recipe
    b) added 1/4 cup black sambucca
    c) added 1/4 cup B&B
    All 3 versions were great for our party goers
    none who knew what was in the mix.
    I did tell them that ALL 3 versions had some
    alcohol content

    1. Kate

      Sounds like a great party, Edward! Thanks for commenting.

  18. Deborah

    Hi Kate!

    Have you ever frozen any of your watermelon juice to use at a later date when watermelons are out of season? I was just wondering is it would still be good and safe to drink?

    Thanks,

    Deborah

    I am gluten free have been since 71 am 79 So like only gluten free receipts my hubby cooks so we do exchange regular noodles for gf

  20. Colleen

    Looks wonderful! Do you know how long it might last in a ball jar in the fridge? Thank you!

    1. Kate

      Hey Colleen! I’d say about 4 to 5 days. That’s about standard for homemade recipes. Hope that helps!

  21. Francis

    Great recipe suggestions, Thanx for the Watermelon Juice Recipe.

    1. Kate

      Thank you!

  22. Christina

    Ohh! Watermelon is one of my favorite items. Nice to hear that you are a Vegetable enthusiast. Really I’m also a vegetarian. I love any planet based juice recipe. Really planet based item is so essential for human food because of we are destroying our eco-balance to be fulfilled our demand. Day by day are decreasing our animal sector. That’s why all are should more publish & share this type of recipe, food to increasing public awareness. Thanks & keep it up.

    1. Kate

      Thanks for the review, Christina!

  23. rose

    I sometimes buy a watermelon that taste good but has that bad texture I just put it in the blender and drink it I use to just throw them out but now I drink it very refreshing drink.

    1. Kate

      Thank you!

  24. flgirl

    I saw watermelon juice today at the farmer’s market selling for $4 a bottle. It looked so refreshing so I bought a whole watermelon instead for $4 and am making my own. Thanks, great recipe and great idea!

    1. Kate

      You’re welcome! How did it go?

  25. E Harry Leland

    Kate, why are you discarding the seeds?
    The seeds are lovely on our colon, as well as nutritious in their own right.
    Also too, I discovered by using my fancy pants nice juicer, the water that comes out at the end is easier to drink in large quanties if one is doing a cleanse.
    I loved the story and hope your move was all you were looking for.

  26. Teri Cristobal

    Had a small watermelon that was too soft to eat like normal… glad I found your post and made the juice. So yummy and refreshing! Made several versions… with squeeze of lime, with a shot of Limone gin, with a splash of lemonade – all good. Didn’t realize how delicious and simple this drink was. Love ×3!

    1. Kate

      Thanks for your review, Teri!

  27. Edward Foster

    Beautiful color! I am intrigued by the book your recommended, adding it to my list of books to read! I can’t wait to try this juice. I love that your recipe . :)

    1. Kate

      Thank you, Edward!

  28. Ellen

    I made some watermelon juice from an organic melon purchased a few days before. When I take a drink, initially it’s delicious but has an icky aftertaste, like I’m drinking the rind (none of which went into the juice). Is it always like this or should I try again.

    1. Kate

      Thanks for sharing, Ellen!

  29. John

    I just made some pickled watermelon rind and have all this flesh left over. If I make the entire melon into juice how long can it be kept if refrigerated or can it be frozen once blended with the lime juice? Could a lemon be used instead of lime?

    1. Kate

      Hi John! It should keep covered for a few days. It didn’t last that long for me. Let me know! I would judge by color and taste.

  30. Donna Goodman

    I am not clear how long I can keep it. I placed it in the blender, then place the watermelon juice in a jar. I went to add some to my smoothie and it appears to be separating and have a different taste? The bottle seems swollen? Is it bad

  31. Rimmy

    Your watermelon takes me back to the tropics party in the blue ocean. So fresh and hydrate juice!!!

  32. Ahimbisibwe Syson

    how many lemons can you put in one water melon and what can you put in the juice to prevent it from separating in case you want to pack and market

    1. Kate

      I’m not sure, sorry!

  33. Chris

    Thanks for the recipe I will really go for and I get back to you for results.
    Chris

  34. Karen Masters

  35. Deborah Johnson

    I love watermelon so much now i found a new way of using watermelon I’ll for now on and I’ll still eat it…… Thanks for sharing.

  36. Sheila

    So easy and refreshing! I got a giant watermelon at Costco and wasn’t sure we’d eat it before it went bad…glad I found your recipe. We don’t have any tequila or rum on hand, but I did see a cocktail recipe with watermelon, whiskey, and ginger beer that might be worth trying…

  37. Tashina

    Made this (lime included) and it is DELISH!!!! So Yum!!!

  38. Marvella

    I bought an organic watermelon and although the watermelon wasn’t as sweet as I’d hoped, it was still really good!
