When I updated my collection of 25 Low-Carb Cucumber Salads, I mentioned that this Cucumber and Radish Salad with Feta Dressing needed a new photo, and I’m so happy to be able to share photos that I hope will entice you to try this; it’s one of my long-time favorite summer salads!

It’s really the flavorful dressing with Feta cheese that makes this Cucumber and Radish Salad salad such a winner, but when I first posted this recipe (in 2010!) It took a bit of experimenting to get the salad just right; feedback from recipe testers on the first two attempts asked for smaller pieces, more feta, and less vinegar flavor in the vinaigrette, and I thought those changes made the salad better.

I used small, crisp Persian cucumbers (also called mini cucumbers) in the salad to make the radishes and cucumbers more equally crisp. Of course if you’re lucky enough to have fresh garden cucumbers, definitely use them in this salad but I wouldn’t use large watery cucumbers with a lot of seeds. The Persian cucumbers didn’t need to be salted to draw out water, and that kept the leftover salad good in a fridge for a day, so they were a perfect choice. You might think cucumbers and radishes are an unusual combination for a salad, but I promise if you like both those vegetables you’ll make this easy salad over and over like I do!

How to Make Cucumber and Radish Salad with Feta Dressing:

(Scroll down for complete recipe with nutritional information.)

  1. Cut eight Persian cucumbers in half lengthwise, then into half-moon slices about 1/2 inch thick. I didn’t peel the Persian cucumbers, but if you don’t have this thin-skinned type of cucumber, you might want to peel some strips of skin off.
  2. Trim stem and root ends of radishes and wash, then cut radishes in half lengthwise and cut into slices just slightly thinner than the cucumber pieces.
  3. Toss radishes and cucumbers together in a bowl.
  4. I adapted a Creamy Feta-Red Wine Vinegar Salad Dressing recipe from David Lebovitz to make the dressing.
  5. Start by mashing together feta, red wine vinegar, and chopped fresh thyme (or crushed dried thyme will work in a pinch.)
  6. Then stir in  olive oil and buttermilk and stir the dressing together. I loved the tang of buttermilk in this, but if you’re not a buttermilk fan you could use milk, or just use water like David did.
  7. Stir the dressing into the cucumber-radish mixture, season with salt and fresh ground black pepper to taste, and serve the Cucumber and Radish Salad with a bit more crumbled feta sprinkled on top. YUM!

Cucumber and Radish Salad with Feta Dressing

Yield 6 servings
Prep Time 15 minutes
Total Time 15 minutes

It's the interesting dressing that makes this Cucumber and Radish Salad with Feta Dressing so delicious!


  • 8 small Persian cucumbers (or other small cucumbers without large seeds)
  • 12 large radishes
  • 1/2 cup + 1/4 cup crumbled Feta cheese
  • 1 T red wine vinegar
  • 1 1/2 tsp. chopped fresh thyme (see notes)
  • 1 1/2 T olive oil
  • 3 T buttermilk (see notes)


  1. Cut ends off cucumbers, cut in half lengthwise, then cut into half-moon slices about 1/4 inch thick.
  2. Wash radishes and trim ends, then cut in half lengthwise and cut into half-moon slices just slightly thinner than cucumbers. Put cucumbers and radishes into salad bowl.
  3. Put 1/2 cup crumbled feta into a bowl or measuring cup. Add chopped fresh thyme (or crushed dried thyme) and red wine vinegar and mash slightly with a fork. (I like to leave it a little chunky.) Stir in olive oil and buttermilk (or use regular milk or water if you prefer.)
  4. Stir the dressing into the salad. Season to taste with salt and fresh ground black pepper (I didn’t use much salt.)
  5. Serve with the extra 1/4 cup crumbled feta sprinkled over the salad.
  6. This will keep in the fridge for a day or two, but it’s better freshly made.


You can use 1/2 tsp. crushed dried thyme, but fresh thyme is definitely better. If you don't have buttermilk just use regular milk or water to thin the dressing.

The dressing in this recipe adapted from Creamy Feta-Red Wine Vinegar Salad Dressing from David Lebovitz.

  1. This was delicious. Even someone who didn't like radishes had seconds!

  2. What a lovely salad. I have so many cucumbers and now i know what I will be making with them.

  3. This sounds and looks like a delightful summer salad with a refreshing combination of ingredients. I like the use of the buttermilk dressing!

  4. Lovely and healthy recipe, like always Kalyn. That is what I should eat instead of eating leftover chocolate peanut and caramel cake for supper and breakfast!!

  5. yum!
    Chef Chuck

  6. The really cold weather has settled in here, yet I strangely find myself craving your salad!

    The combination of crunch and sharp sounds inspired and a friend found for me a tin of real Bulgarian feta, off to the greengrocer I think.

  7. The colors in the finished salad are really lovely. You've given me food for thought. I have no recipes for radishes in my files. This recipe is a great place to start. I hope you are having a wonderful day, Kalyn. Blessings…Mary

  8. This looks wonderful Kalyn. You have so many great salad ideas!

  9. A lovely summer's salad, dear Kalyn!! yeah!!!

  10. Mmm. Looks delicious. I think I would substitute the buttermilk for Greek yogurt instead. It has a nice thick consistency but healthier. Thanks, Kalyn!

  11. One will never run out of great salad recipes with your blog, Kalyn! This one looks great, too. I'm ready to try radishes again. I've never had mild radishes actually. They always seemed pretty potent to me, but maybe I haven't been exposed to the right ones yet. Love all the colors in this salad. It's the right time of year for everything cucumber. 🙂 I just made "bruschetta" using cucumber. 🙂


  12. This dressing sounds delicious! This whole thing sounds so refreshing.

  13. very nice information and look forward to reading more and great recipes.

  14. The colors are fantastic, and as I'm a butternut fan, I'm definitely adding this to my summer menus.

  15. Home-grown radishes are just the best! Glad people are liking the sound of this.

  16. I love radishes – the only ones I had last summer were a fat bunch that a farmer pulled out of the ground for me in Upstate NY. Those tasted particularly good, given the circumstances, as I'm sure the ones from your garden do.

  17. Gorgeous colors. So excited that radishes are in season.

  18. Looks SO good Kalyn!

  19. My husband is a big radish fan! I don't mind them but I forget to buy them. This looks awesome, I'll book mark it to try, thanks!

  20. Your radish recipes always make me want to run out and buy a bunch of them (or raid a neighbor's garden). This dressing is inspired!
