The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading all the way through for any tips or substitute suggestions, to ensure that you have any specialized ingredients and equipment required and that you understand the steps and timings involved.

This watermelon mint lemonade is super easy to make and is so refreshing on a hot summer day. This is one of those recipes you’ll want to tinker around with to find the right flavor combination for your tastes. For example, the amount of water you need to add will vary depending on how juicy the watermelon is and how strong you want the flavor to be.

Directions for a mint-infused simple syrup are included. The watermelon adds a lot of sweetness, however, so you may not wish to sweeten it further. It really depends on how sweet or tart you want the final results to be.

If you are serving this recipe outside on a warm day, make extra so you can freeze some into ice cubes or an ice ring (if serving in a punch bowl). Using ice cubes made of the beverage you are serving rather than plain water will prevent watered-down drinks as the day or evening progresses.

For an adults-only variation, add some citrus-flavored vodka before serving.

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online.

It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. Please note, you can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Watermelon Mint Lemonade

Yield: 4-6
Prep Time: 15 minutes
Cook Time: 8 minutes
Total Time: 23 minutes

Let’s take classic lemonade to a whole new level with this tantalizingly refreshing Watermelon Mint Lemonade. It can be easily transformed into an adult beverage using citrus vodka if desired. Summer refreshment just got way more interesting!


For the Mint Simple Syrup

  • ½ cup granulated sugar
  • ½ cup water
  • ¼ cup tightly packed fresh mint leaves, stems removed and crushed

Remaining Ingredients

  • 6 cup fresh watermelon, cut into chunks
  • ¾ cup fresh lemon juice (6-8 medium lemons)
  • ½ cup cold water, (plus more, if needed)
  • ½ cup fresh mint leaves, tightly packed with stems removed
  • Ice, to serve
  • fresh mint sprigs, for garnish
  • lemon slices, for garnish


  1. To prepare the simple syrup, add the sugar, water and crushed mint to a small saucepan and heat over medium heat. Stir for 2-3 minutes, until the sugar dissolves completely. Reduce heat to low and simmer for 5 minutes. Remove from heat and strain to remove mint leaves. Set aside to cool.
  2. Add the watermelon chunks, fresh lemon juice, and cold water to a blender and blend until smooth. Pour through a strainer to remove any larger particles. Taste and sweeten with the cooled mint-infused simple syrup, as desired.
  3. Bruise one-half cup fresh mint leaves with fingers to release oils and add to a large glass pitcher or jar. Top with the watermelon mixture and stir to combine. To serve, pour over ice and garnish with a sprig of fresh mint and a slice of lemon. Enjoy!
