PIN the Cucumber Radish Salad to try it later!

Cucumber Radish Salad (with Feta Dressing) is without a doubt one of my favorite summer salads! This combination is so refreshing, with the coolness of the cucumbers, a little zing from the radishes, and so much creaminess and flavor from the Feta dressing. 

I do love cucumbers and radishes, but it’s really the flavorful dressing with Feta cheese that makes this salad such a winner for me. And it’s definitely cucumber salad weather, so today I’m reminding you about this salad for my Friday Favorites pick!

You might think cucumbers and radishes are an unusual combinatio. But I promise if you like both those vegetables and enjoy Feta Cheese you’ll make this easy summer salad over and over!

How did we make this salad even better?

When I tried this salad with cucumbers and radishes it took a bit of experimenting to get it just right. Feedback from recipe testers on the first two attempts asked for smaller pieces of cucumber and radish, more Feta, and less vinegar in the vinaigrette. I agree those changes made the salad even better, and love the salad recipe you see here..

What cucumbers did I use for Cucumber Radish Salad?

For this salad I used small, crisp Persian cucumbers (also called mini cucumbers) to make the radishes and cucumbers both equally crisp. Of course if you’re lucky enough to have fresh garden cucumbers, use them! 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. 

What Feta did I use for Cucumber Radish Salad?

I’m a huge fan of creamy sheep’s milk Feta, and lately I am swooning over Kirkland Organic Feta from Greece. But any type of Feta you like the flavor of will be great in this easy salad!

How to make Cucumber Radish Salad with Feta Dressing:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. Cut eight Persian cucumbers in half lengthwise, then into half-moon slices about 1/2 inch thick.
2. 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.
3. 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.
4. Toss radishes and cucumbers together in a bowl.
5. I adapted the Creamy Feta-Red Wine Vinegar Salad Dressing recipe from David Lebovitz to make the dressing.
6. Start by mashing together feta, red wine vinegar, and chopped fresh thyme (or crushed dried thyme will work in a pinch.)
7. Then stir in  olive oil and buttermilk and stir the dressing together.
8. I loved the tang of buttermilk in this, but if you’re not a buttermilk fan you could use milk, or just use water.
9. Stir the dressing into the cucumber-radish mixture, and season with salt and fresh ground black pepper to taste.
10. If you’re a huge Feta lover like me, serve the Cucumber Radish Salad with a bit more crumbled feta sprinkled on top. YUM!

Make it a Low-Carb Meal:

For a low-carb summer meal, the Cucumber Radish Salad would be amazing with one of these main dishes:

• Grilled Lamb Chops
• Marinated Beef Kabobs
• Grilled Chicken with Lemon and Capers
• Grilled Cuban Flank Steak
• Grilled Cod with Garlic, Basil, and Lemon.

Ingredients

Toggle ingredient group

• 8 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)

Instructions

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 salad with cucumbers, radishes, and Feta dressing will keep in the fridge for a day or two, but it’s better freshly made.

Notes

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.
