This refreshing cucumber and radish salad comes together in just 15 minutes with no cooking required. Thinly sliced cucumbers and peppery radishes are coated in a creamy Greek yogurt dressing infused with fresh dill, garlic, and a bright splash of lemon juice.
It's a light, vibrant side dish that pairs beautifully with grilled fish, works well as part of a mezze spread, or stands on its own as a quick lunch. Naturally vegetarian and gluten-free.
The summer I grew cucumbers in a bucket on my apartment balcony, I had more cucumbers than any single person could reasonably eat. A neighbor knocked on my door holding a bunch of radishes from her garden, and we stood in the hallway brainstorming what to do with our unexpected harvest. That casual conversation birthed the best cold salad I have ever thrown together in fifteen minutes.
I brought this to a potluck once and watched a woman who claimed to hate radishes go back for her third helping without a trace of guilt on her face.
Ingredients
- 2 medium cucumbers, thinly sliced: English cucumbers work beautifully because their seeds are small and their skin is tender, but any fresh firm cucumber will do the job.
- 1 bunch radishes (about 8), thinly sliced: Look for radishes that feel heavy for their size with crisp green tops still attached, a sign they were pulled recently.
- 1 cup (240 g) plain Greek yogurt: Full fat yogurt gives the richest mouthfeel, but two percent also works if that is what your fridge holds.
- 2 tbsp fresh dill, finely chopped: Dried dill can sit in quietly if fresh is unavailable, though you will want only about two teaspoons of the dried version.
- 1 clove garlic, minced: One clove is enough to warm the dressing without taking over the entire bowl.
- 1 tbsp lemon juice: Fresh squeezed brightens everything, so avoid the bottled stuff here if you can help it.
- 1 tbsp extra virgin olive oil: A grassy, peppery oil rounds out the tang of the yogurt and lemon.
- Salt and freshly ground black pepper: Seasoning is everything in a raw salad, so taste before you serve.
Instructions
- Prep the vegetables:
- Slice the cucumbers and radishes as thin as you can manage, aiming for coins that are almost translucent, because thin slices drink in the dressing beautifully.
- Whisk the dressing:
- In a small bowl, stir together the yogurt, dill, garlic, lemon juice, olive oil, salt, and pepper until the mixture is smooth and no streaks of oil remain floating on top.
- Combine and toss:
- Pour the dressing over the vegetables and fold gently with a large spoon or spatula, taking care not to crush the delicate slices.
- Taste and adjust:
- Take a small bite on a spoon and decide if it needs another pinch of salt or a squeeze more lemon to wake up the flavors.
- Chill or serve:
- Let the salad rest in the refrigerator for ten minutes if you have the patience, or serve it right away on a warm plate beside anything grilled.
That neighbor and I still trade garden extras every July, and this salad has become our unofficial handshake of summer friendship.
Serving Suggestions
Pile this alongside grilled salmon or lamb kebabs and you have a meal that feels like a Mediterranean holiday without leaving your patio.
Storing Leftovers
The salad keeps well covered in the refrigerator for up to two days, though the vegetables will soften and release some liquid as they sit.
Quick Variations to Try
Once you master the basic formula, a handful of small changes can shift the personality of this salad entirely.
- Scatter toasted walnuts or sunflower seeds over the top right before serving for a satisfying crunch.
- Swap Greek yogurt for an unsweetened coconut or almond yogurt to make the dish completely plant based.
- Arrange it on a large platter with hummus, olives, and warm flatbread for an effortless mezze spread.
Keep this recipe in your back pocket for every hot evening when cooking feels like too much to ask of yourself. It rewards you with freshness and asks almost nothing in return.
Recipe FAQs
- → Can I make this cucumber radish salad ahead of time?
-
Yes, you can prepare it up to 4 hours in advance. Keep it covered in the refrigerator. The cucumbers may release some water, so give it a gentle stir before serving and adjust the seasoning if needed.
- → What's the best way to slice the cucumbers and radishes?
-
Use a sharp chef's knife or a mandoline slicer for thin, even cuts. Aim for about 1/8-inch thickness for both vegetables. Thin slices absorb the yogurt dressing better and create a more delicate texture.
- → Can I use regular yogurt instead of Greek yogurt?
-
Greek yogurt is preferred because its thick, creamy consistency coats the vegetables well without making the salad watery. If using regular yogurt, strain it through cheesecloth for 30 minutes first to remove excess moisture.
- → How long does this salad last in the fridge?
-
It's best enjoyed the same day, but leftovers will keep for up to 24 hours in an airtight container. Beyond that, the cucumbers lose their crunch and the dressing becomes watery.
- → What can I substitute for fresh dill?
-
If fresh dill isn't available, use one tablespoon of dried dill weed. Alternatively, fresh mint or flat-leaf parsley work well and give the salad a different but equally delicious flavor profile.
- → Is this suitable for a vegan diet?
-
Simply swap the Greek yogurt for a plain, unsweetened plant-based yogurt such as coconut or almond yogurt. The rest of the ingredients are already vegan-friendly.
