  • 6 cups ripe seedless watermelon cubed
  • 1 cup water optional


  1. Place watermelon in a high-speed blender. Turn blender on medium speed and work up to high speed, until watermelon is completely smooth. Use tamper if necessary.
  2. Add water to watermelon juice, if desired. Keep in an airtight bottle for 1-2 days.

Recipe Notes

I personally prefer the watermelon juice without extra water added, but you can add water--as much or as little--as you like!
