When I think of smoothies I think sweet, like this berry avocado smoothie or perhaps this kiwi mango smoothie. Both delicious, both healthy, and both noticeably sweet. Today however we are trying something a little different and a lot less sweet, with this cucumber avocado smoothie.
Today’s smoothie is still made of fruit as both cucumbers and avocados are fruits, berries to be exact. They probably aren’t the things that come to mind when you think of berries, but because they grow from a single flower and encase their seeds inside, they really are berries. However, their sweetness is much more subtle when compared to a banana or grapes, which are ironically berries as well.
This smoothie calls for only four ingredients half of which are in the name. In addition to the cucumber and avocado, we add cilantro and lime. If you want to get crazy with it and up those ingredients to five, you can add a dash of salt to turn up the flavor impact. I drank the first half of mine without it, then added a bit of pink Hawaiian sea salt and it was pretty awesome.
Like most smoothies, this one requires some sort of blender or food processor. I used my immersion blender with the mini-food processor attachment, but one of these days I’ll upgrade to a professional level blender to make my smoothies as smooth as possible.
The cucumber takes the most work. It needs to be peeled and seeded. A Kuhn Rikon Y-Peeler makes super quick work of any peeling job and just over $2 each it’s by far the best bargain I’ve found for my kitchen.

Once it’s peeled, slice it in half and use a small spoon to scoop out the seeds. I used an espresso spoon like this one, but an iced tea spoon or even a baby spoon would be a good fit. It makes for very quick work of removing the seeds. Place half of the cucumber into your blender.
Cut the avocado in half, remove the seed and scoop the flesh from both sides directly into the blender. Add in the juice of half a lime, about 1/2 cup of cilantro leaves, and a 1/2 cup of water. Puree it until smooth. Then give it a taste.

Mine needed a little bit more lime, but just a squeeze. Add the salt if you want, or don’t. If you prefer a thinner smoothie, add a bit more water to the mix. Give it one last mix with the blender and serve immediately.
This cucumber avocado smoothie is a refreshingly delicious take on a green fruit smoothie and a great way to start your day or even drive some energy back into the middle of your afternoon. Lots of fruit, a bit of herbs, and no guilt. Enjoy!

This is actually the smoothie that I want to try. I wonder how cucumber tastes in smoothies. Looks so delicious! Pinning:)
Cucumber in a smoothie is so refreshing! Think cucumber water in a concentrated form. Mine had little pulpy bits of cucumber, but if you have a high end blender I’m sure they would be obliterated.
What a wonderful start to the day or midday pick up! I love this creamy, refreshing drink….definitely must try this!
Let me know what you think!
I am a huge fan of cucumber in juices and smoothies. I agree with you that it is so refreshing. This sounds like the perfect mid-afternoon pick-me-up.
Yes! Much better than a caffeine jolt and crash in the afternoon.
MMm this looks beautiful! Such an interesting combination of ingredients – I need to try this!
I love the idea of using cucumber. Going to try it in my new blender!
Lucky you!! I need a new blender.
I love the idea of using cucumber in a smoothie – I like cucumber water, so totally makes sense. Looks like a healthy way to start the day 🙂
That was exactly my thought! Love cucumber water, why not cucumber smoothie?!
What a delicious, healthy smoothie to start the day with! Looks so good!
Thank you!
Ingredients look delicious but tried this recipe and its a bit to be desired. Could really use some acidity to balance it out. Not a fan but those are just mine and my wife’s tastes.
Jeremy, Thank you for taking the time to come back and comment after trying the recipe! It sounds like your’s may have used a bit more lime juice. Sometime half of a lime does it and, like I mentioned in the post, other times it needs a bit more. To satisfy your tastes, try upping the lime and maybe the salt too. Cheers!
Can I substitute lemon instead lime? Margaret
Margaret, you can absolutely substitute lemon for the lime. I like the flavor better with lime, but with a lemon tree growing in my backyard it’s easier to make a substitution than take a trip to the store. Try it both ways and see which one you like best!
