2-Ingredient Watermelon Lime Slushie
A refreshing and naturally sweet two-ingredient watermelon lime slushie, perfect for cooling down or soothing an upset stomach. Its simple, whole-fruit approach provides hydration and natural electrolytes without added sugars.
For 1 serving
Prepare the watermelon: Cut approximately 300g (about 1.5 cups) of fresh watermelon into 1-inch cubes, ensuring all seeds are removed. For best results, use a seedless variety.
Freeze thoroughly: Arrange the watermelon cubes in a single layer on a parchment-lined baking sheet or plate. Place in the freezer for at least 4 hours, or preferably overnight, until completely solid. This is crucial for achieving the ideal slushie texture.
Juice the lime: Just before blending, cut a fresh lime in half and squeeze the juice from one half directly into your blender jar. Ensure no seeds fall into the blender.
Combine ingredients: Add the solidly frozen watermelon cubes to the blender with the fresh lime juice.
Blend to perfection: Secure the lid and blend on a high setting, starting with short pulses, then continuously, until a smooth, icy slushie consistency is achieved. If the mixture is too thick to blend, add 1 to 2 tablespoons of cold water, one at a time, and continue blending until smooth.
Serve immediately: Pour the slushie into a chilled glass and serve at once to enjoy its frosty texture and refreshing flavor.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Pre-chill your blender jar: Place your blender jar in the freezer for 15-20 minutes before blending to help maintain the slushie's icy consistency for longer.
- 2Seedless watermelon is best: Opt for seedless watermelon to save time on preparation and ensure a perfectly smooth slushie without any gritty bits.
- 3Adjust tartness: Taste the slushie after blending and add a tiny bit more lime juice if you prefer a tangier flavor. While designed to be naturally sweet, a small drizzle of agave or honey can be added if your watermelon isn't very sweet.
- 4Use a high-powered blender: A high-speed blender will yield the smoothest slushie with minimal effort, but a regular blender will work with a bit more patience and by stopping to scrape down the sides as needed.
Adapt it for your goals.

Frequently asked questions
No, freezing the watermelon is essential to achieve the thick, icy slushie texture without adding regular ice, which would dilute the flavor and make it watery. The frozen fruit is the 'ice' here.
