These watermleon slushies are literally summer in a glass.  Nothing is better on a hot, humid, sweltering summer day than these frosty babies.  They have it all: sugar sweet watermelon flavor combined with zesty, tangy lime juice and fresh, sweet, herby mint.  The more ice you add the frostier they will be.

This recipe is super simple and only requires four ingredients that you puree in your blender: watermelon, ice, fresh mint and fresh lime juice.  When I make them for my kids I leave out the mint and lime.  They love the frosty watermelon + ice combination.  It is a great way to keep them hydrated.

I love how incredibly refreshing and hydrating watermelon is in the summer heat.  Watermelons are 92% water and contain electrolytes, vitamin A, vitamin B1, vitamin B6, vitamin C, potassium, lycopene, fiber, magnesium and amino acids. They pack in so much nutrition and happen to be the #1 budget friendly fruit.

Here are my favorite watermelon selection tips for the perfectly ripe, sweet and juicy watermelon…

  1. Pick it up – it should feel heavy for its size (means it is full of water).
  2. Inspect it – It should be firm, symmetrical and free of bruises, cuts or dents in the rind.
  3. Look at the underside of the melon – it should have a creamy yellow spot from where it sat on the field and ripened in the sun.
  4. Sniff it – a sweet aroma means a sweeter melon!

A brilliant red interior indicates a sweet melon.  

You can easily turn this recipe into popsicles by omitting the ice and pouring just the pureed watermelon, mint and lime juice into popsicle molds.

You could also add a splash of vodka, rum or tequlia for a summery adult beverage.

Watermelon Mint Lime Slushies

Summer in a glass! Refreshing. Hydrating. Sugar sweet. Minty. Tangy. Frosty. This recipe only requires four ingredients that you puree in your blender: watermelon, ice, fresh mint and fresh lime juice. Super simple and yet so satisfying.



  • 1/2 small seedless watermelon (about 7 cups), diced into 2 inch cubes*
  • juice from 12 large juicy limes
  • 1015 fresh mint leaves (no stems)
  • 68 cups of ice (depending on how frosty you want it)


  1. In a blender add the watermelon, mint leaves and fresh lime juice. Blend until no watermelon chunks remain to make more room in your blender for the ice (about 20 seconds). Next, add ice and blend again for about 20 seconds. The longer you blend the less frosty it will be so it just depends on your preference.
  2. Taste and add more lime juice for more tanginess and/or more mint for more sweet, fresh, herby flavor. I sometimes add more ice on really hot days when I want it extra frosty. This recipe is pretty forgiving in terms of the ratios so find what works best for you.
  3. Serve immediately. The longer you wait, the more you will notice the icy slushie part rising to the top of the glass and the juicy part sinking to the watermelon. You can always refresh it with a quick whirl in the blender with a handful of ice cubes.


* Or, one entire mini seedless watermelon

To make this for my kids I leave out the lime and mint. They love just the fresh watermelon blended with the ice cubes. It is a great way to use up leftovers and keep your kids hydrated.

If a spritzer is more your style, top it off with some sparkling water.

I haven’t tried this yet with basil or cilantro in place or mint but I imagine either would work and would be a fun spin on the recipe.
