Watermelon Slushie Recipe: The Ultimate Summer Chill-Out Drink

There’s nothing quite like this Watermelon Slushie recipe to cool you down on a scorching summer day. I mean, seriously, watermelon is practically summer’s mascot, and when you blend it into a frosty, minty, lime-kissed slushie? Pure magic in a glass. I first whipped this up during a backyard hangout when I had way too much watermelon and not enough patience for fruit salad. One blender whirl later, and boom, everyone was hooked. This slushie is light, refreshing, naturally sweet, and just a little zippy thanks to the lime. It’s the kind of drink that feels like vacation, even if you’re just on your fire escape. Perfect for sunny afternoons, casual brunches, or whenever your inner thermostat screams “ice, please!”

Okay, real talk, this Watermelon Slushie recipe is one of those magical things that somehow manages to be super easy and wildly satisfying all at once.

I’ve tested it more times than I can count (purely for research, of course), and every time, it hits the spot. Here’s why it totally works:

• Fresh mint or basil takes it to a whole new level: Trust me, this is the kind of small touch that makes people go, “Wait…what’s in this?!”
• You can totally make it your own: Whether you’re adding sparkling water, swapping herbs, or spiking it with a splash of rum, this recipe adapts like a pro.

Ingredients

• 10  cups frozen seedless watermelon cubes

• 3 Tbsp maple syrup

• 1 large lime juice

• 0.25  cup fresh mint or basil

• 1.5  cups filtered or sparkling water

Directions

• Let frozen watermelon rest for 5–10 minutes – This softens the edges, making it easier to blend.
• Add ingredients to blender: watermelon, maple syrup (start with 2 tablespoons), lime juice, mint or basil, and water.
• Pulse to break up – Start with short pulses to break the frozen watermelon into chunks.
• Blend to slushie texture – Blend on high speed for 30–45 seconds until smooth and thick.
• Taste & adjust – Add more maple syrup if needed, or a bit more water to thin it to your desired consistency.
• Serve immediately – Divide into four glasses, garnish with lime or mint, and enjoy cold.

Notes

• Use food processor if no high-speed blender.
• Adjust sweetener based on watermelon sweetness.
• No fresh herbs? A dash of lime zest adds a bright kick in place of mint or basil.

My Go-To Tricks for Nailing This Watermelon Slushie

I’ve made this watermelon slushie more times than I can count, and every time I whip it up, I pick up a new little trick to make it even better. Whether you’re blending for one or making a big batch for a crowd, these simple tips will help you get the perfect texture and flavor every single time.

• Freeze in single layers: Spread watermelon cubes on a baking sheet before freezing so they don’t clump together.
• Zest the lime first: Add a little lime zest to the blender for an extra pop of citrus flavor.
• Go easy on the sweetener at first: You can always add more, but it’s hard to take it back!
• Scrape down the sides: If your blender gets stuck, stop and give everything a quick stir or shake.
• Serve immediately: This slushie is best right after blending, it’s super frosty and refreshing.
• No blender? No problem: A food processor works just as well if your blender isn’t high-speed.
