Wicked Watermelon Slush Mocktail Recipe
I keep coming back to this watermelon slushie mocktail because it’s just so easy and refreshing. Sweet watermelon pairs up with mint, lime, and a splash of sparkling water for a summer drink that always hits the spot.
Equipment
- Blender (for blending everything up)
- Freezer-safe container (to freeze the watermelon cubes)
- Knife and cutting board (for chopping watermelon and strawberries)
- Citrus juicer (to get that fresh lime juice)
- Measuring cups and spoons (for honey, coconut water, and the rest)
- Stirring spoon (to give it all a quick mix)
- Serving glasses (for the finished mocktail)
- Shallow dish or plate (if you want a lime sugar rim)
- Zester or grater (for a little lime zest on top)
- Fine mesh strainer (if you’re not into pulp)
Ingredients
- 4 cups seedless watermelon (cubed and frozen)
- ½ cup fresh strawberries (hulled and sliced)
- ½ cup coconut water (for extra hydration)
- Juice of 2 limes (freshly squeezed)
- 1–2 tablespoons honey or agave nectar (to taste)
- ½–1 cup sparkling water (chilled)
- Handful of fresh mint leaves (plus more for garnish)
- Lime zest (optional, for garnish)
- Coarse sugar (for the lime sugar rim)
- Ice cubes (optional, if needed)
Instructions
- Chop up the watermelon and toss the cubes in a freezer-safe container. Let them freeze for at least 3 hours, or until they’re solid.
- Throw the frozen watermelon, strawberries, coconut water, honey (or agave), and lime juice into your blender and blend until smooth.
- Add in the fresh mint leaves and pulse just enough to mix—don’t overdo it, or you’ll lose that bright green.
- For the lime sugar rim, rub a lime wedge around each glass and dip in coarse sugar on a plate.
- Pour the watermelon slush into your glasses.
- Top off each glass with chilled sparkling water, give it a gentle stir, and you’re good to go.
- Garnish with extra mint, lime zest, or a strawberry slice if you’re feeling fancy.
Notes
This turns out best with super ripe, sweet watermelon—otherwise, I’ll sneak in a bit more honey or agave.
You can totally swap coconut water for regular water, but coconut adds a nice, subtle twist. Sparkling water brings a fun fizz that makes the drink a bit more lively.
Don’t skip freezing the watermelon cubes if you want that proper slushy texture. If you’re in a rush, toss in some ice cubes, but heads up: it’ll water down the flavor a bit.
The lime sugar rim is a little extra, but it looks great and adds some zing. Just dip the rim in lime juice, then sugar.
Kids love this one, and hey, no alcohol—so it’s perfect for everyone.

Tasting Notes
That first sip? The natural sweetness of the watermelon jumps out, but it’s not overpowering or syrupy—just fresh and cooling.
Every sip is super refreshing, and honestly, on a hot summer day, it’s exactly what I crave.
The crushed ice gives it that perfect frosty, slushy feel. Makes it hard not to gulp it down all at once.
What I really like is how you can taste the actual fruit—nothing fake or artificial. Plus, knowing watermelon brings in some vitamins and minerals makes me feel a little better about reaching for a second glass.
A chilled glass, that clean coolness, and the crisp watermelon flavor all come together for a mocktail that’s just plain refreshing.
I honestly look forward to every sip!

Substitute
Sometimes, I just don’t have every single ingredient for my Wicked Watermelon Slush Mocktail. No big deal—there are plenty of easy swaps that work in a pinch.
Fruit Substitutes:
- If watermelon’s missing from my fridge, I’ll grab cantaloupe or even honeydew.
- Frozen strawberries or mango chunks? Honestly, they’re fantastic for a different vibe.
Sweetener Options:
- Out of honey? I’ll go with maple syrup or agave, whatever’s within reach.
- Some days, I just want things less sweet, so I’ll choose a low-calorie sweetener.
Citrus Choices:
- If I’m out of lemon juice, lime juice totally steps in.
- Orange juice brings a whole new twist, and I’m not mad about it.
Herb Alternatives:
- Mint’s gone? Basil actually works, trust me.
- Sometimes I’ll toss in a pinch of fresh rosemary—why not?
For extra fizz, I’ll add club soda instead of something sweet.
If I’m feeling clever, I’ll freeze juice for the ice cubes, which keeps the slush extra smooth.
