Watermelon Cucumber Popsicles

Summer is here and keeping everyone hydrated in the heat of the season can be such a challenge!

I mean, you can only nag kiddos so much to drink water. So, to keep nagging to a minimum but still ensure that my crew is hydrated during these hotter months, I love to keep healthy popsicles in my freezer to grab at a moment’s notice.

Why these Watermelon Cucumber Popsicles are great!

  • Just 3 ingredients. Watermelon, cucumber and lime! That’s it! I love a minimal recipe that is good for me!
  • No added sugar. Lots of commercially prepared ice pops have oodles of added sugar in them. These watermelon popsicles are sweetened only with fruit! If you like a sweeter pop, feel free to add a tablespoon or two of coconut sugar to the blender. Even then, they will still be far lower in sugar than most popsicles on the market.
  • They are hydrating. Watermelon and cucumber are naturally high in water content. Creating a popsicle from these two refreshing fruits of nature is a delicious way to help keep your family hydrated while they think they are enjoying a frozen treat.

Suggested adaptations for making Watermelon Cucumber Popsicles.

  • Use whatever kind of cucumber you have on hand. I used an English cucumber. If you use a different type of cucumber that has a lot of seeds, cut your cucumber in half lengthwise and scrape out the seeds with a spoon before dicing.
  • Add a few fresh mint leaves! This makes for a really refreshing flavor combo if your family enjoys mint.
  • Blend in a few fresh or frozen strawberries. This will add extra sweetness and flavor or add sliced strawberries to the popsicle mold before filling with the blended watermelon for an extra pretty and tasty popsicle.
  • Use frozen watermelon. Since watermelon is so high in water, the pulp can separate from the juice before freezing. The taste will still be lovely, but the popsicle might be a bit more ombre in appearance. If you want a popsicle that is one solid pink color, freeze some watermelon chunks before blending to help slow the separation process while the pops freeze.
  • Don’t have popsicle molds or want to enjoy a frozen treat right away? Make a cucumber watermelon slushy! Blend ingredients above with a few handfuls of ice and serve with a spoon!

Tips on making these healthy popsicles with kids.

This magical and easy watermelon popsicle recipe is the brainchild of the awesome Heather from Happy Kids Kitchen. She is the queen of delicious recipes AND helps parents/caregivers get children into the kitchen.

With this amazing summer recipe, she is also serving up some helpful bits of wisdom for how to include children in making these Watermelon Cucumber Popsicles.

1. Knife skills! This is a great recipe for kids to practice using an age appropriate knife, especially since the cucumber and watermelon will be blended in the end. Cut the watermelon into large but flat pieces then let your child cut them smaller and place them in the blender. Kids can also help peel the cucumber then cut it into small chunks. If you’d like some advice on helping toddlers and younger kids use a child-safe knife, you can check out my blog post on Teaching Knife Skills.

2. Use the blender. Take this opportunity to review how to safely use a blender: never place your hands inside the blender, use the blender only with an adult’s supervision, and really make sure the lid is on tightly before you turn it on. With my preschool cooking classes, we make using the blender extra fun by doing a countdown and then covering our ears when I flip the switch. “5,4,3,2…1!”

3. Help pour! This is job is probably best for older kids, but younger ones can help hold the blender as you fill the popsicle molds or even help tell you when the mold is starting to get full.
