We’re going green today folks with a super healthful and refreshing Cold Thai Cucumber Avocado Soup with Cucumber Relish with Greek yogurt, tangy lime juice and cilantro.  A splash of Sriracha hot sauce provides the right amount of heat.  A light and crunchy cucumber relish on the top puts this refreshing soup over the top!  What’s not to love on a hot summer day?

I’ve found there are two types of people in this world–those who love cold soups and those who do not.  I recently suggested gazpacho for a client who wanted soup.  She responded by vehemently using the “h” word to convey her feeling on the subject.  Know not to go there anymore!

I’m in the first category and love cold soups.  I’ll admit it was a little strange at first.  Soup should be hot, steamy and warm you to your soul, right?  I then started to make my Very Veggie Gazpacho all those years ago and that opened my mind to cold soups.  I now make my gazpacho at least once each summer.

How to make Cold Thai Cucumber Avocado Soup with Cucumber Relish:

  • Cold Thai Cucumber Avocado Soup with Cucumber Relish is as easy as combining all the soup ingredients in a blender.
  • A food processor will work if you have one that does not leak.  A blender is one kitchen appliance I don’t have and my food processor leaks!
  • If you don’t have a blender or food processor, simply combine all the ingredients in a deep bowl and use an immersion blender.  An immersion blender is one of the handiest tools you can have in your kitchen!
  • Then, add texture and crunch by hand chopping the Cucumber Relish.

Make this Cold Thai Cucumber Avocado Soup with Cucumber Relish dairy-free / vegan by using coconut or soy yogurt.  The soup thickens during refrigeration, so just add water as necessary and adjust the acidity with lime juice and the heat with additional Sriracha.

This flavorful soup makes an elegant starter for a Thai-inspired meal or with a salad for a wonderful light lunch.

Stay cool!

    So delicious!!! I am a spicy/salty girl, so I added a Serrano and a splash of fish sauce for umami flavor. Overall just lovely! This is a keeper!! Thank you!!

  2. Hey! Just came across this recipe and it looks delicious! I would like to know if I could freeze this soup and how long I can freeze it for?

    1. Hi, Jess, Thanks so much for your question. I would prepare to the point of adding the yogurt. Add the yogurt when you’re ready to enjoy/serve. I think it should be fine for 3-4 months without the yogurt. Thanks again and hope you enjoy!

  3. Hi, Can you please send me the recipe for this? I’m not seeing it. Any portions also will be using coconut milk instead of yogurt. Thanks in advance.

    1. Hi, Brandi, I checked to make sure a glitch didn’t happen but the recipe is definitely there at the bottom of the post. Perhaps give it another try? Thanks so much and I think coconut milk or coconut yogurt would be just fine.

    1. Hi, Kristine, Thanks so much for your question! A plant-based yogurt should work just fine. Thanks again and hope you enjoy!

  4. I would like to make this for a “Going Away” lady’s luncheon. How far in advance can I make it?

    Hi, this is a great cold soup. However, in which ingredients are you arriving at that ginormous carb count? It just doesn’t seem right.

    1. Hi, Timm, Thanks so much! I’m using a program for that. I actually really hate including nutritional counts because they’re always off unless you research each ingredient. I’m going to be changing my program again in the next month or two so hopefully can get more accurate information. So glad you enjoyed! It’s really perfect for summer!

  6. Thanks for this great recipe, will make tomorrow! We make at least three cold soups every week during the summer. Liquid salad + something grilled = a perfect dinner. Make your soup early in the day so it has plenty of time to “mature” into icy wonderfulness.

    1. Hi Lizzie! I am preparing to make this soup for a small gathering and wondering if you have recommendations for what pairs well as the main dish? We were thinking grilled salmon (perhaps on a salad?) Wondering if you have thoughts on spices?

      Thanks so much! Have a great day!
