When the sun is shining and the temperatures rise, there’s nothing quite as refreshing as a cool and fruity drink to quench your thirst. Enter the watermelon slushie! Bursting with juicy sweetness and a hint of tanginess, this frozen treat is the perfect way to beat the summer heat. Here’s how to make a delicious watermelon slushie that will leave you feeling refreshed and satisfied.


  • 4 cups of fresh watermelon, seeded and cubed
  • Juice of 1 lime
  • 2 tablespoons of honey or agave syrup (adjust according to your desired sweetness)
  • Ice cubes


  1. Start by placing the cubed watermelon in a blender. Blend until smooth and liquefied.
  2. Add the lime juice and sweetener of your choice (honey or agave syrup) to the blender. Blend again until everything is well combined.
  3. Next, add a handful of ice cubes to the blender. This will help create the slushie texture. Blend on high speed until the mixture turns into a slushie consistency.
  4. Taste the slushie and adjust the sweetness if needed by adding more honey or agave syrup.
  5. Once you’re satisfied with the taste and consistency, pour the watermelon slushie into glasses or bowls.
  6. Optional: Garnish your watermelon slushie with a slice of fresh watermelon, a sprig of mint, or a squeeze of lime for an extra touch of flavor and presentation.
  7. Serve immediately and enjoy the icy, refreshing goodness of your homemade watermelon slushie!


  • For a tangy twist, add a small amount of lemon or orange juice to the slushie mixture.
  • For a tropical twist, blend in a handful of frozen pineapple or mango chunks along with the watermelon.
  • For an adult version, add a splash of your favorite clear spirit, such as vodka or rum, to the blender and blend briefly until combined.
