Halved watermelon filled with our refreshing Watermelon Slushie recipe

If you follow me on Snapchat (username: minimalistbaker) and Instagram, you probably already knew I had a sexy watermelon recipe coming your way. I share all of my secrets on social media, just in case you were wondering (wink, wink).

I’ve already divulged all the details of my watermelon obsession here, so there’s no need to sing my love for this ruby-red fruit all over again.

Instead, I have a super simple, summery recipe for you that’s perfect for when you want something sweet, healthy, and refreshing on sweltering-hot days.

I present the Watermelon Slushie.

Parchment-lined baking sheet with chunks of watermelon for freezing

This recipe requires just 3 ingredients and a blender! Frozen watermelon creates a slushie base, light coconut milk complements the flavor while adding creamy texture, and lime juice injects some acidity to balance the sweetness.

Friends, get ready to fall in love. I even made a recipe video to show you how it’s done! Check it out.

If you give this recipe a try, let us know! Leave a comment, rate it, and take a picture and tag it #minimalistbaker on Instagram! We’d love to see what you come up with. Cheers, friends!

Ingredients

WATERMELON JUICE

  • 1 small seedless watermelon (cubed)

WATERMELON SLUSHIE

  • 4 cups frozen watermelon (3/4-1 small seedless watermelon yields ~4 cups or 616 g)
  • 1 medium lime (juiced)
  • 1/3 cup light coconut milk
  • 1/2 cup watermelon juice (plus more to ease blending)
  • 1 Tbsp sweetener of choice (optional // such as maple syrup or honey if not vegan)
  • 1 pinch sea salt (optional)

Instructions

  • Halve a ripe seedless watermelon and scoop out rounded Tablespoon amounts (or cube with a knife). Arrange on a parchment-lined baking sheet. Freeze until firm – about 3-4 hours.
  • In the meantime, halve another small seedless watermelon and add the fruit (leaving the rind behind) to a blender. Blend on high, adding a touch of water if needed (I didn’t), until completely smooth and pureed.
  • OPTIONAL: Drape a large, thin dish towel over a mixing bowl and pour over juice. Then gather corners, lift up and squeeze the juice out leaving the pulp behind – there shouldn’t be much, but this makes the juice extra smooth. Transfer to a mason jar, cover, and refrigerate – should keep for 3-4 days, or more.
  • Once watermelon is frozen, add ~ 4 cups (amount as original recipe is written // adjust if altering batch size) frozen watermelon (I found 4 cups was about three-quarters of one small watermelon), coconut milk, lime juice, and watermelon juice to a blender and blend on low until creamy and smooth. You will need to scrape down the sides and blend on low to encourage it along. If it has trouble blending, add a bit more watermelon juice, but not too much or it will become too thin.
  • Once the slushie is blended and smooth, taste and adjust flavor as needed. Add more coconut milk for creaminess, lime for brightness, a pinch of salt to enhance sweetness, or sweetener of choice to sweeten. Blend and sample again – repeat as needed.
  • Serve in empty watermelon rinds or chilled serving glasses and garnish with a lime wedge.
  • This recipe serves 2 generously. Best when fresh! TIP: Freeze leftovers in Popsicle molds.

  1. Daphne says

    Absolutely delicious! And yet, our was more liuqid than slush texture. The taste is exquisite. Will share with everybody thoa heavenly mix!

  2. Steph says

    Looks soooooo good!!
    A few questions…
    Can you use regular canned coconut milk?
    Is straining the watermelon for the juice required?
    Any suggestions for the best alcohol to add for an adult version?? ;)
    Very excited to make this!!

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      Yes, you can use that kind of coconut milk. You don’t have to strain! I’d say coconut rum would be the best addition! That or you could try a spin on our watermelon margs.

  3. Nichole says

    I had a craving for a boozy watermelon drink over the weekend and took to Google. I found your easy recipe, made it, and absolutely looooooved it! It was definitely a hit. I made a batch without booze and a batch with Dominican rum. I didn’t have time (or patience) to freeze the watermelon so I added ice to the blender, and also didn’t add watermelon juice, and that all worked out well! ALSO, I used a yellow watermelon, which was super cool. It was so good that a squirrel came by and drank the leftover slushie (posted pictures at theothercat.com of the squirrel — super cute!).

  4. Molly says

    Looks SO good! Quick question – is the coconut milk the kind from a can or the kind you find in the fridge section with regular milk?

    • Avatar for Dana @ Minimalist BakerSupport @ Minimalist Baker says

      Hi Molly! Coconut milk from a carton you find in the refrigerated section works! Additionally, tetra-cartons will work too.

  5. Lacee says

    Delicious! I subbed out the watermelon juice in favor of coconut water and it was a little bit less sweet, which I preferred.

  6. Rebecca Friedland says

    Great recipe. I made them last weekend and they see thoroughly enjoyed!! I’d like to make them again but have a guest who is allergic to tree nuts (coconut). Any replacement suggestions?? I love your site! ?

      • Amy says

        A few years late here but coconut is a fruit, so people with tree nut allergies aren’t allergic to coconut in general. Also, someone who has a tree nut allergy would be allergic to almonds so this is not a great suggestion in any case.

  7. Miles says

    I’m really glad there was a video because for whatever reason both my partner and myself could not figure out the written instructions. We were confused because it says “halve” the watermelons, but then mentions 3/4s, and so we weren’t sure how much to freeze or how much to blend for juice. But from the video it looks like a whole watermelon for each? and then you just have leftover pieces/juice?

  8. Julianna Horvath says

    I love the idea! Another of a million reasons to by watermelon!
    I also love that in all your recipes you are also corn free!
    XOXOXOXOXOXOX

  9. Ruby says

    My mom usually hates watermelon but the way the coconut made it creamy she instantly fell in love! Also they are wonderful as Popsicles! :)

  10. Anne says

    Hi Dana. Just like Amanda I really love these gorgeous photos with the colored background. How do you do it? Is it some sort of paper? ;) Have a lovely weekend!

  11. Jessica Levin says

    This looks so amazing! Planning on making it this weekend. Any reason my nut bag wouldn’t work for making the juice?

  12. Farha - faskitchen says

    wow.. I am just thinking when the recipe looks so fabulous, how great it would be to taste… this looks like a show stopper during these hot months

  13. karen says

    I really love this! I love the video too! It makes everything look so easy! Trying this watermelon slushie for sure, you’re so creative! Your recipes rock! (I’m always checking them out even though I’m not always commenting) hehe!

  14. Elizabeth @ Pineapples and Polka Dots says

    Oh my goodness, these look amazing! I am on a huge watermelon kick right now, and love just about every kind of frozen treat, so I can’t wait to try this recipe!

  15. Rebeca says

    This was such a refreshing, delicious treat! I’m a watermelon lover, so this will have to happen often this summer. Thank you!

  16. Sarah | Well and Full says

    This looks great, Dana! So perfect and refreshing for summer :) Do you recommend using canned coconut milk or boxed?

  17. anick says

    hi Dana –
    i have become an addict of Minimalist Baker.
    Just did the watermelon slushie for my kids and of course, took all the credit for the “you are the best mom ever”!
    Thank you for all the wonderful recipes, keep them coming please!

  18. Monique @ Ambitious Kitchen says

    1. LOVE THIS RECIPE. It screams summer!
    2. UMMMM VIDEOS? You two are the cutest.
    xoxo

  19. ines @ between kitchens says

    I’ve been dreaming about making watermelon popsicles for days, but I couldn’t find the moulds I wanted at any nearby store yet… so something like this was actually coming into my mind! It looks delicious and so beautiful inside its ‘bowl’ that I feel compelled to go buy a watermelon rightaway to make it!
    Have a nice week!

  20. Kathryn - The Scratch Artist says

    Wow. What a great idea. I really don’t even like watermelon (I know, I know I’ve heard it all before) and I want to have this!
    I love the video!

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      Thanks Kathryn! You MUST try this smoothie! It’s summer’s perfect beverage!

  21. Kate says

    This looks amazing! All the best summer flavors in one fruity, cooling drink! It’s perfect timing too, seeing as we’re having an oppressive heatwave here in Berlin. Thanks for this – love the video!

  22. Heather @ My Overflowing Cup says

    This looks absolutely delicious and refreshing. Thanks so much for sharing your recipe.

    I make smoothies often, but I am thinking a coconut lime watermelon slushie is in order.

    Happy 4th!

  23. Amanda @ Sweets and Greens says

    Yes, you know I’ve been waiting for this, wondering what ingredients you would use. I love the idea of the coconut milk to add some creaminess.
    I’m also loving the new look boards you are using. I really like the white backgrounds that you use as well, but these coloured ones just make your food pop.

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      Thanks Amanda! I’m having a little too much fun with all these colored backgrounds ;D

  24. Michelle Regan says

    What!? This is absolutely adorable. Beautiful colors and a fabulous recipe. Thank you for being you. xoxo

  25. Leah M @ love me, feed me says

    I don’t like watermelon, but I wish I did because this just looks so amazing and so refreshing. Might have to try it anyways…

    Your recipe videos are my favourite! Always so fun and well done.

  26. Abby says

    This is incredible, Dana! SO perfect for summer. Gahhh I need! It’s been way too long since I last had watermelon…

  27. Eve @ Baking the Day says

    This is such a smart idea, I love how you used coconut milk to add richness and a tropical taste. I loved the video, it was so good, Happy 4th July!

  28. Cassie says

    The video was the most high quality and well edited cooking tutorial I’ve ever seen! Please please please make more!

  29. Katelin says

    This looks so delicious and refreshing!! I loved the video. I’m curious what the song was is the video!!
