How to Pick a Good Watermelon
Selecting the flavorful watermelon is VERY important for the success of your slushie. Since this slushie is made with just 2 ingredients, if the watermelon you chose is bland, then the slushie will turn out to be bland. Here are some tips to choosing a ripe and flavorful watermelon:
- Pick a watermelon that feels heavy for its size
- The watermelon should have a deep yellow/orange field spot.
- When you tap the watermelon it should have a hollow sound.
- The skin of the watermelon should be dull, and not shiny.
With these tips, you should be able to select the perfect watermelon for a delicious watermelon slushie!
Ingredient Notes
*This is just a recipe overview. The full recipe ingredients, measurements and instructions can be found below in the recipe card.

- Watermelon: Choose ripe, juicy watermelon and cut it into small cubes before freezing. Watermelon is also really fun to use to make Watermelon Pizza!
- Lime Juice: Freshly squeezed lime juice adds a zesty kick to balance the sweetness of the watermelon.
How to Make a Watermelon Slushie

Step 1: Cut up the watermelon and place in the freezer overnight or for at least 4 hours. Then transfer to a blender with lime juice.

Step 2: Blend together until it forms a slushie texture. If the texture is too thick you can add a splash of water or juice.

Step 3: Transfer the slushie to your glasses and garnish with some lime, watermelon or a sprig of mint.
Jess’s Tips
- Prep Ahead: Cut your watermelon into chunks and freeze them in a single layer on a baking sheet before transferring to a freezer bag. This ensures quick blending and prevents clumping.
- Add Liquid Sparingly: Start with a small amount of lime juice and adjust according to your taste preferences. You can always add more, but you can’t take it away!
- Texture Matters: For a slushie with the perfect consistency, blend the frozen watermelon in short pulses until it reaches a slushy texture. Avoid over-blending, or you’ll end up with a watery slushie.
- Sweeten Naturally: If your watermelon isn’t as sweet as you’d like, try adding a touch of honey or agave syrup to sweeten the slushie.
- Garnish: Garnish your slushie with a wedge of lime, a sprig of mint, or a slice of watermelon on the rim of the glass.
Frequently Asked Questions
You can use fresh watermelon however you’ll end up with more of a watermelon juice than slushie. If using fresh watermelon make sure to add a big handful of ice cubes!
Watermelon slushies are best enjoyed fresh, so I recommend making this recipe right before serving.

This hit the spot and was way more refreshing than I expected. It only took a few minutes to make and came out light, icy, and really satisfying. Iโve already made it a couple times when I wanted something cold and fruity without a ton of effort. Definitely keeping this one in my back pocket.
