I know you don’t come here to hear me complain about the weather, so I’ll spare you the details. It’s hot, and when the temperature rises there’s nothing better than a cold, revitalizing drink. This Coconut Lime Watermelon Slushie is one of my go-to summer treats—simple to make, bright in flavor, and incredibly refreshing.
This slushie combines sweet watermelon, zesty lime, a hint of coconut and fizzy citrus soda for a light, tropical twist. We use frozen watermelon cubes so the drink becomes thick and icy without needing a lot of ice or added sugar. It’s fast to prepare, family-friendly, and perfect for cooling down after outdoor play, pool time, or a long day in the sun.
We make these slushies often at home because they’re so easy—and everyone loves them. The recipe is forgiving: if you prefer a sweeter drink, add a touch of honey or agave; if you want it more tart, increase the lime. The slight coconut flavor pairs beautifully with the watermelon and gives the slushie a vacation-like vibe.
No need to stop for slushies at the gas station—this homemade version is fresher and you can customize it to suit everyone’s tastes. Keep reading for the full ingredient list, step-by-step instructions, and helpful tips for serving, storing, and varying the recipe.

Description
The perfect way to cool down this summer—easy to make, light, and super refreshing. This Coconut Lime Watermelon Slushie combines frozen watermelon, citrus soda, fresh lime juice and a hint of coconut to deliver a bright, icy drink in minutes. It’s ideal for hot afternoons, backyard gatherings, kids’ parties, or whenever you want a quick, cooling beverage.
Ingredients
- 1 1/2 cups frozen seedless watermelon cubes
- 1 cup ice cubes
- 1 can citrus flavored soda (I used a zero-sugar soda like Fresca)
- Juice of one fresh lime (about 2 tablespoons)
- 1/8 teaspoon coconut extract
Notes: If you prefer a less fizzy texture, reduce the soda slightly and add a splash of chilled water. For a creamier variation, substitute a small amount of coconut milk for part of the soda.
Instructions
- Place the frozen watermelon cubes, ice, citrus soda, fresh lime juice and coconut extract into a blender jar.
- Start the blender on low and gradually increase speed until the mixture becomes smooth and slushy. If the blender struggles, stop and scrape down the sides, then blend again.
- Check the texture. If it’s too thick, add a splash more soda or a little cold water and blend briefly. If it’s too thin, add a few more frozen watermelon cubes or ice.
- Taste and adjust: add a bit more lime for brightness or a few drops of sweetener if you prefer sweeter slushies.
- Pour into chilled glasses and garnish with a lime wheel, mint sprig, or a small watermelon wedge. Serve immediately with a straw.
Tips, Variations and Storage
Tips: Use evenly sized frozen watermelon cubes for the smoothest blend. If you plan to make this for a crowd, prepare extra frozen watermelon ahead of time. A high-speed blender yields the best texture, but a regular blender works with a little extra pulsing and scraping.
Variations: Add a handful of fresh basil or mint for a herbal note. For a tropical twist, stir in a tablespoon of cream of coconut or use coconut water instead of soda for a lighter option. To make an adult version, add a splash of rum or vodka.
Storage: Because this slushie is best enjoyed fresh, avoid storing it once blended. If you must, keep leftovers in a covered container in the freezer and scoop briefly into the blender to re-smooth before serving.
