Cucumber Avocado Salad is filled with crisp cucumbers, rich creamy avocado, and fresh summery dill. It’s all tossed in a simple fresh lemon dressing. 

This avocado salad makes the perfect summer side in just minutes! It’s great alongside almost any meal on the grill or makes a filling lunch on its own.

A Fresh Summer Salad

I summer for the produce and the fresh summer salads. We frequently make an avocado salad or a cucumber salad but in this recipe, we put them together for the perfect crisp side dish.

Most often I make cucumber salad with a creamier dressing or a sour cream/Greek yogurt base so this fresh dill dressing is not only easy, it’s a bit lighter in flavor!

Cucumbers to Use in this Avocado Salad

English Cucumbers – While any variety of cucumber will work in this avocado salad recipe, I prefer to use a long English cucumber (or seedless cucumber).  They tend to have thinner skin and fewer seeds, making them the perfect addition.  

You can peel English cucumbers if you’d like but there really is no need.

Other –If using a field cucumber, they often have a thicker skin so you can peel it if you’d like and use a spoon to scrape out the seeds.


If you’re looking for a delicious and simple dish to dig into, you’re going to love this Cucumber Avocado Salad.  


  • Cut the avocado into cubes and immediately toss with a little bit of lemon juice; this keeps it from getting brown (and adds flavor).
  • This recipe really relies on the flavor of fresh ingredients so use fresh lemon juice. Bottled juices can sometimes have a bitter aftertaste.


  • Depending on the size of your cucumbers and avocados, you may not need all of the dressing. Mix it in a mason jar and add a little bit at a time.  
  • If you happen to have extra, it’s perfect over a tossed salad and will last about a week in the fridge!


  • I love the flavor (and little bit of color) red onion adds to this Cucumber Avocado Salad.
  • If you don’t have red onion, you can certainly add in sweet white onions. Be sure to use onions with white papery skin (not the typical yellow-skinned onion), they’re sweeter and milder.  
  • To take a little bit of the “bite” out of the onion (and make it milder) soak the onion in cold water while preparing the cucumbers and avocado. Optional of course!

Enjoy it Fresh!

The lemon juice will keep the avocado from going brown for a couple of hours but this recipe is best consumed within a couple of hours.

If you’d like to prepare this ahead of time or keep leftovers, prepare all of the ingredients except the avocado. Add the avocado at the time of serving.

  • Tossing the avocado with lemon juice keeps it from turning brown and adds flavor. Use fresh lemon juice for the best flavor.
  • White onion can be used in place of red onion. Yellow onions are too harsh in this salad and not recommended.
  • Soak the onions in a bit of ice water to take a little bit of the “bite” out (and make it milder). Optional of course!
  • Depending on the size of your cucumbers and avocados, you may not need all of the dressing. Leftovers are great add over a tossed salad.

  1. Could you substitute lemon juice for the vinegar. I’m not a fan of that vinegary taste. Plus the lemon juice will help keep the avacado from browning. I don’t know if vinegar does that or not.

    1. Hi Linda, we have not tried subbing out the vinegar for lemon juice but it sounds like it should work out. I would love to hear how it turns out for you, Linda!

  2. Loved this salad, the dressing was a bit sweet, I added more wine vinegar and lemon to reduce sweetness. Thanks for sharing!5 stars

    1. It’ll last only about a day if you add the avocado. The dressing itself will keep for about a week. To extend the time you can keep it in the refrigerator, I’d suggest mixing up and adding the avocado shortly before serving. It’ll last about 4 days that way. Enjoy Cella!
