These Watermleon Mint Lime 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: naturally 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 easy recipe is refined sugar-free, vegan, grain-free, nut-free and dairy-free.
- 1/2 medium watermelon (about 7 cups), diced into 2 inch cubes*
- juice from 2 large juicy limes (add the zest too for a stronger lime flavor)
- 6-8 cups of ice (depending on how frosty you want it)
- 15 fresh mint leaves (no stems)
- a little water to thin if needed
- 1 teaspoon maple syrup (optional - if your watermelon isn't naturally very sweet)
- In a blender add the watermelon, fresh lime juice and zest (if using). 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.
- Add mint and blend for 10-20 seconds (too much blending can make the mint taste bitter or soapy)
- 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. If it is not sweet enough add a little maple syrup. To thin it out add just a little water.
- 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.
* You can use a seedless or regular watermelon with black seeds. We usually buy regular watermelon with seeds and blend the seeds right up in the slushies for added nutrients. It doesn't impact the flavor or texture at all!
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.
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. See my easy Watermelon Popsicles here.
You could also add a splash of vodka, rum or tequlia for a summery adult beverage.
