This refreshing Watermelon Basil Cooler is a perfect summer drink that combines sweet watermelon, fresh basil, and a hint of lime for a zesty twist. Lightly sweetened with honey or agave syrup and topped off with sparkling water, it’s a naturally hydrating and flavorful beverage served chilled, ideal for hot days or casual gatherings.

Ingredients

For the Watermelon Basil Cooler

  • 4 cups seedless watermelon, diced
  • 1/4 cup fresh basil leaves, chopped
  • 1 lime, juiced
  • 1-2 tablespoons honey or agave syrup (optional)
  • Sparkling water, as needed
  • Ice cubes, as needed
  • Basil sprigs, for garnish

Instructions

  1. Blend Watermelon and Lime Juice: In a blender, combine the diced watermelon and freshly squeezed lime juice. Blend the mixture until smooth to create a fresh watermelon juice base.
  2. Strain the Juice (Optional): For a smoother texture, strain the blended watermelon juice through a fine mesh sieve to remove any pulp, ensuring a clear and refreshing drink.
  3. Mix with Basil and Sweetener: Pour the watermelon juice into a pitcher, add chopped fresh basil leaves and honey or agave syrup if desired. Stir well to combine the flavors evenly.
  4. Prepare Serving Glasses: Fill glasses with ice cubes to chill the drink and keep it refreshing.
  5. Assemble the Cooler: Pour the watermelon and basil mixture over the ice-filled glasses. Top each glass with sparkling water to add effervescence and lighten the drink.
  6. Garnish and Serve: Stir gently to combine, then garnish each glass with a sprig of fresh basil. Serve immediately while chilled for maximum refreshment.

Notes

  • Adjust the amount of honey or agave syrup according to your preferred level of sweetness or omit it entirely for a naturally sweet drink.
  • Using seedless watermelon makes blending easier and avoids having to strain out seeds.
  • For a non-carbonated version, substitute sparkling water with cold still water or coconut water.
  • Fresh basil is key to achieving the distinctive herbal note; dried basil is not recommended.
  • This cooler is best served fresh but can be prepared a few hours ahead and kept chilled in the refrigerator.
