  • 1.5 cups frozen watermelon cubes
  • 1 cup frozen strawberry
  • 1 lime juice
  • 1.5 teaspoon honey or any other sweetener – sugar, stevia. Don’t add any sweetener if watermelon has enough sweetness
  • 2 teaspoon chia seeds
  • 2 tablespoon chilled milk or chilled water or chilled almond milk for vegans – optional


Frozen Fruits –

  • It all starts with fresh ripe watermelon. Buy fresh ripe watermelon preferably without seeds. If watermelon got seeds in it, make sure to remove all seeds before you start blending into smoothie.
  • I prefer to cut watermelon into discs, then cut out the outer green rind leaving behind ripe watermelon squares. Cut the squares into 1 inch cubes. Remove any seeds present on watermelon.
  • Store the cubes in zip lack bags and freeze it.
  • Pro-Tip – definitely use frozen fruits for thick smoothie consistency.
  • I prefer to use 1.5:1 ratio of frozen watermelon to frozen strawberries. For every 1.5 cups of frozen watermelon, use 1 cup frozen strawberries.

Taste Enhancers –

  • Lime juice in watermelon makes it taste much better. Lime juice also adds hint of tart kick to the smoothie balancing out the sweetness of the watermelon.
  • We call for honey in this smoothie recipe for sweetness enhancement. In place of honey you can add stevia, sugar. DO NOT ADD ANY SWEETENER if your watermelon has enough sweetness to it.

Packing In Nutrients –

  • Few teaspoons of chia seeds in the smoothie packs more nutrients in the smoothie. You can either replace chia seeds with flax seeds, hemp or add these along with chia.

Liquids –

  • To add or not to add liquids will majorly depend on your blender and ofcourse your taste buds. Since we are using frozen fruits, your blender should be powerful enough to break down frozen fruits and make a smooth, thick smoothie.
  • Frozen fruits when blended is more like slushie consistency. I love to drink it up with straw directly. So good!
  • If you prefer to add liquids, choose one of the below –
  • Ice cubes
  • Chilled water
  • Chilled milk
  • Chilled almond milk (for vegan option).
  • Note – If using fresh watermelon (not frozen) do not add any liquids. It will thin down the smoothie consistency.

Serve It Right Away -

  • Always serve smoothie right away. This watermelon smoothie made from frozen fruits will have slushie like consistency when served immediately. The longer you wait, the icy parts starts separating and float to the top leaving down the juice sink down the glass.
  • Smoothie tastes better when served chilled.
