  • 4 cups watermelon, cubed
  • 1/2 cup lime juice
  • 1/2 cup granulated sugar


  1. Heat the lime juice and sugar in a small saucepan over medium heat.
  2. Stir the juice frequently until the sugar has completely dissolved. Turn off the heat and set the juice aside.
  3. Remove all seeds from the watermelon and puree in a blender until completely smooth.
  4. Add the lime juice and blend until mixed.
  5. Strain the mixture to remove any remaining pulp and pour into a large glass or metal baking dish.
  6. Place the baking dish on a flat surface in your freezer.
  1. After 30 minutes, use a fork to scrap any ice crystals off the side or bottom of the baking dish and stir them back into the liquid.
  2. Repeat the process of scraping ice off the side every 20 to 30 minutes until it is completely frozen and has the texture of a slushie.
  3. Give the granita one final stir with a fork, breaking up any large chunks of ice. You want the dessert to have a shaved ice texture when it is finished.
  4. Leave it in the freezer, uncovered, for 30 minutes to an hour once it is frozen. This will help dry the surface of the ice and get the texture right.
  5. Store in an air-tight plastic container or serve immediately with a little fresh whipped cream.

Tips For Watermelon Granita Recipe

  • Make sure to get all the seeds out of the watermelon before you put it in the blender. Just one seed can flavor the entire mixture if it goes through the blender. Buying seedless watermelon is a great option to avoid this.
  • There are tons of different watermelon dessert recipes that you can make. My favorites are watermelon sorbet and watermelon popsicles. You can actually use either of those recipes to make granitas too, so you can try two different frozen desserts at once!
