It’s that time of year when my husband plops a couple of cucumbers from the garden on the counter and wants me to use them. Never mind that he doesn’t eat cucumbers so what ever I make I have to eat by myself.
Well I had a few avocados, limes and some cilantro hanging around and thought they would be good together. So I threw everything in my high speed Vitamix blender and in seconds I had this tasty cold cucumber & avocado blender soup! It was rich and creamy and very satisfying as a cold low carb soup.
The Best High Speed Blender IMO
First a note about my Vitamix blender. I bought it on QVC years ago and have used it at least once a day, everyday. It makes such wonderful:
- smoothies
- ice cream
- purees
- silky smooth soup like this one
- bullet proof coffee and tea
- mousse too.
I’m sure there are other really good blenders out there too but I have definitely got my money out of this one and wanted to share that with you.
Cold Cucumber Soup Ingredients
As I mentioned, I used some vegetables from our garden, specifically a large cucumber and a jalapeno. Of course there is also avocado, lime juice, lime zest, garlic, salt and cilantro. I think next time I will try some coconut milk too. It will give it a little bit of Thai flavor I think.
Some Notes About This Cucumber Recipe
- First of all this is very thick as you can see from the photos or from the little video. You can thin it out with water, chicken broth or as I suggested above, some coconut milk.
- Secondly I used half of a jalapeno that I thoroughly cleaned out the ribs and seeds. It was not hot at all. I think next time I’m keep the seeds and ribs in because I like heat. But not everyone does.
- Lastly, taste add a bit more of any of the components you like. You might want to use more fresh garlic or cilantro or like me more jalapeno. Go for it!
Well I hope you like this super easy summer soup recipe! It’s a good way to use fresh summer vegetables and you will feel good about eating so healthy. The nutritional information for 1 serving is:
