Boozy Watermelon Lemonade and Gin Slushies

This homemade watermelon-lemonade recipe is a knockout with your favorite gin. I like to make the lemonade and then combine it with lots of ice and gin in a blender to make an ice-cold slushie. Garnish with a lemon and a rosemary sprig. Take THAT, 100-degree heat!!

Serves 6 (thanks to @piccantedolce for the recipe!)



  • 3/4 cup sugar
  • 2 cups water
  • 4 sprigs rosemary
  • 1 cup lemon juice – fresh squeezed
  • 7 cups watermelon – cut into a 1″ dice – approx. half a medium watermelon
  • 8 ounces gin
  • 1 lemon – thinly sliced
  1. Place sugar and 1 cup of water in a small saucepan; add rosemary sprigs. Cook over medium heat stirring until the sugar dissolves. Once dissolved, remove from heat, cover saucepan and let sit for at least an hour to infuse.
  2. In a blender, combine the lemon juice with cubed watermelon. Add the watermelon in batches, blending in between each addition.
  3. Add in the rosemary simple syrup 1/4 cup at a time until the mixture is at your desired sweetness. I use about a cup.
  4. Pour the mixture into a large pitcher and add 1 cup of cold water, and the gin. Stir to combine. Serve in jars garnished with a lemon slice and half of a rosemary sprig. (Again, combine everything into a blender with lots of ice to make slushies!)
