Watermelon is one of the most nostalgic foods of summer. When I think back to my childhood, there was always a watermelon on the counter or cubed in the fridge while school was out of session. I’ve had a weird journey with this fruit haha! When I was really little my mom said I enjoyed it but around seven years old for some reason, I started not liking it. Fast forward to my 20s and I’m in love with this sweet summer fruit again.

There’s so much going on during summer, kids are out of school, tons of parties and barbecues happen, the Forth of July, and summer road trips. This easy and natural watermelon lemonade is perfect to whip up in a few minutes when you want something sweet and refreshing. A tall glass of watermelon lemonade goes great with a slice of sourdough bread, alongside an arugula chicken sandwich for lunch, or with cajun chicken alfredo for supper!

A Healthy Summer Drink

There are so many terrible ingredients included in pre-made drinks at the grocery store. From powerful chemicals disguised as food coloring to extreme amounts of sugar causing the risk of diabetes. That’s why it’s so important to create delicious treats from scratch at home like this watermelon lemonade.

You know exactly what the ingredients are and you get to control how much you put in! Lemons, watermelons, and water are so good for your body. Cane sugar is a much better swap for refined white sugar or corn syrup while still sweetening your drink just a bit.

Watermelon Lemonade Ingredients

  • 2 lemons
  • 6 cups watermelon
  • 1 1/2 cups water
  • 1/2 cup cane sugar

With only four ingredients, you don’t have to spend tons of time preparing this recipe. I selected each one with nutrition in mind and of course NO FOOD DYES EVER!

Watermelon Lemonade Instructions

The instructions are easy enough that a 10-year-old could make it (if the watermelon was cut up). You first start by juicing the lemons with your hands or a hand-held lemon juicer. Next, you’ll add the lemon juice and cane sugar to a large pitcher preferably made of glass. Then you’ll slice up or scoop out your watermelon and add to a blender for 30-40 seconds on high. Finally, you’ll strain the watermelon into the pitcher, add water, and stir until everything is dissolved. Serve over ice and enjoy!

*it is important to use fresh lemons for this recipe for the perfect flavor (not bottled lemon juice)
*when straining the watermelon use a fine mesh strainer to reduce pulp in your lemonade (you’ll need to use a spoon to help strain the juice through)
* When storing this watermelon lemonade it may separate in the fridge. Simply stir it before serving and it’ll taste perfect!
