Blended Watermelon Lemonade (3 ingredient)

This refreshing watermelon lemonade is made with 3 basic ingredients and is the perfect pick-me-up drink to sip on during a hot summer day! I like to drink this watermelon lemonade over ice, but you can also blend ice into the drink or freeze the watermelon cubes to get more of a slushy/frozen drink texture. Either way is deliciously refreshing for any time of the year!

  • Blender (linked below)
  • Cutting board (linked below)
  • Lemon Juicer (linked below)


  • 4 cups watermelon chunks (packed) fresh or frozen
  • 1/4 cup lemon juice freshly squeezed *see note
  • 4-5 tablespoons sugar, honey or agave can be adjusted to taste

For Watermelon Lemonade Slushy:

  • 7-8 Ice cubes or see note below


  • Remove the seeds from the watermelon (unless you are using a seedless watermelon), then place into a large blender along with the freshly squeezed lemon juice, sweetener and ice cubes (optional).
  • Blend all together until smooth, then serve over ice cubes or as is if in slushy form. For slushy: the amount of ice cubes added can be adjusted to get the texture you prefer.


Bottled lemon juice can also be used in a pinch. My personal preference is freshly squeezed, but I have not found a significant difference in taste between the two. 
You can also freeze the cubed watermelon for 24 hours to make a watermelon slushy. If using frozen watermelon cubes you do not need to add additional ice cubes.

Equipment needed for this Blended Watermelon Lemonade:

  • Blender You will need a med-large blender to blend up the components for this watermelon lemonade.
  • Cutting board A cutting board and Chef’s knife make short work of cutting up a watermelon and the cutting board saves your countertop from being scratched in the process.
  • Lemon/citrus juicer If using fresh lemon juice in this blended watermelon lemonade you will need a citrus juicer. I personally prefer to use a juicer with the container attached at the bottom to catch the juice.

Is it better to add ice cubes or to freeze the watermelon cubes?

Honestly, I have only made this blended watermelon lemonade without ice cubes blended in, then I serve it over ice cubes. I’m not much of a slushy lover since my teeth are a bit sensitive to cold, but if I were to make this blended watermelon lemonade in slushy form I would opt to freeze the watermelon cubes over adding ice cubes to the blender. Freezing the watermelon cubes may be more time consuming, but it also keeps the flavors from diluting in the slushy. Ice cubes are a good choice if you want to save the time it takes to freeze the watermelon cubes.

Step 1: Remove the seeds from the watermelon (unless you are using a seedless watermelon), then place into a large blender along with the freshly squeezed lemon juice, sweetener and ice cubes (optional).

Step 2: Blend all together until smooth, then serve over ice cubes or as is if already frozen.


Can I turn this watermelon lemonade into ice pops?

Absolutely! We have been trying lots of different homemade ice pop flavors this summer with the abundance of fresh fruits as well as my daughter’s love of having an ice pop snack while little brother takes a nap (it also serves as great entertainment if I am busy with other projects). If making ice pops for my kids I like to use an organic sweetener such as honey or agave. Simply pour the watermelon lemonade (without the frozen slushy texture) into ice pop molds and freeze for 12-24 hours. To remove the ice pops run warm water over the molds to loosen the ice pop inside.


This watermelon lemonade is best if served fresh, but can be refrigerated for 2-3 days. You may wish to stir the contents of the drink if separation occurs due to being refrigerated. To freeze: freeze in ice cube trays or popsicle molds for an icy treat on a hot day.
