My new favorite summer drink right here! I’m not ever big on drinks because I’d rather get my sugar from a decadent dessert but this is my new exception! It is totally irresistible and the watermelon and lemon flavor combination pairs perfectly together.

Today I went on a gorgeous hike with my brother and I brought this Watermelon Lemonade along. Even though it was an easy hike it was a long hike for me because due to this lame permanent hip injury I went from exercising 6 days a week to exercising 0 days a week for last year and half. But, I made it through the 7 mile hike thanks to this drink :). The thought of getting another taste of this kept me going. Ah and how refreshing it was to guzzle this drink down on a warm day! It has the perfect amount of sweet and tart, and a delicious depth of mellow watermelon flavor.

I could live on this drink this summer! I’m totally in love with it and when you use a good watermelon it just makes it that much better! Now if only I could learn how to pick the perfect watermelon every single time. It’s like with cantaloupe and avocados, if only I could just see what’s inside before making my selection. I follow the recommend tips but still sometimes end up with duds. Luck of the draw right?

The next watermelon treat I want to try is Rachel’s Watermelon Fruit Leather. I love watermelon so my mouth is watering just thinking about that stuff! It looks so good! I need to expand my collection of watermelon recipes and I think that along with this drink definitely needs to be added to our summer to do list.

Watermelon Lemonade

One of my favorite drink recipes! This lemonade is perfectly sweet and tangy and brimming with fresh watermelon flavor.
Servings: 6
Prep15 minutes

  • 6 cups cubed seedless watermelon , chilled (2 lbs after peeling)*
  • 4 cups cold water
  • 3/4 cup fresh strained lemon juice , chilled
  • 2/3 cup granulated sugar (more or less to taste)
  • Ice and fresh mint for serving


  • Add watermelon to a blender and pulse until well pureed (there should be about 4 cups). Pour through a fine mesh strainer into a bowl.

    This recipe is Okay. I think it could use more watermelon, and less lemon and water.

      Yes you could definitely adjust to taste, but I do recommend being sure that you use a good quality, flavorful and sweet watermelon and you may find the ratios are ok :).

    I was having visitors over last minute and needed a refreshing drink. Someone suggested picking up soda (!) but I knew neither these visitors nor I would appreciate soda. Saw that I had lemons and half a watermelon in the fridge so I looked up a recipe that used both and found this. Everyone enjoyed it!!! But I made a few changes….
    Instead of using white sugar, I substituted 1/3 cup of coconut sugar, 1/3 cup monkfruit sweetener and about a half teaspoon of stevia extract powder to sweeten the drink. I actually trimmed the peel, seeded and cut up enough lemons (about 2 medium) to make half of the lemon “juice” needed by pulverizing them in my Vitamix, then added the other half as hand-squeezed strained lemon juice (another 1 or 2 lemons), to which I added the sweeteners and mixed them further before combining with the watermelon juice and cold water. Didn’t have mint on hand. It was delicious and not too sweet!
