  • Yield: 4 servings 1x


  • 3 1/2 cups chopped watermelon
  • 1/4 cup sugar
  • 1 3/4 cups water, divided
  • 1/4 cup fresh lemon juice (from about 4 small lemons)


  1. To make watermelon juice, blend chopped watermelon in a blender until it turns to liquid. Strain through a fine mesh strainer (you’ll want about 2 cups of watermelon juice.) Set aside.
  2. To make lemonade, make a simple syrup on the stove in a small saucepan by whisking together sugar and ¼ cup water. Place over medium heat and heat until just simmering and sugar is dissolved. Remove from heat and let cool a bit.
  3. Whisk in lemon juice.
  4. In a freezable container, mix together watermelon juice, lemonade and remaining 1 1/2 cups of water. Place in freezer and freeze overnight.
  5. Before serving, let sit on the counter for about 10 – 15 minutes until it thaws a bit. Chip at it with a butter knife and then scoop with ice cream scooper into four glasses. Serve with spoons.
