This cool and creamy cucumber salad combines crisp sliced cucumbers and thin red onions with a tangy dressing made from sour cream, mayonnaise, white wine vinegar, and fresh dill. The blend creates a refreshing side dish that's perfect for warm weather dining. With just 15 minutes of prep time and no cooking required, it's an ideal addition to summer meals, barbecue spreads, or picnic baskets. Refrigerate briefly before serving to let the flavors meld together.
The first time I made this creamy cucumber salad was during a heatwave when even turning on the stove felt like a mistake. My grandmother had been making something similar for decades, but I'd never actually written down her method. I ended up improvising with what I had in the fridge, and that happy accident became the version I still make today.
Last summer I brought this to a neighborhood potluck, and honestly, I was worried it was too simple compared to everyone else's elaborate dishes. But halfway through the evening, my friend Sarah pulled me aside and demanded the recipe. She said her husband, who claims to hate cucumbers, had gone back for thirds.
Ingredients
- 2 large cucumbers: English or regular cucumbers both work beautifully here
- 1 small red onion: Thinly sliced for just the right amount of sharp contrast
- 3/4 cup sour cream: Full fat gives the best texture but reduced fat works too
- 2 tablespoons mayonnaise: This adds extra richness that makes the dressing feel luxurious
- 1 tablespoon white wine vinegar: Adds brightness without overpowering the other flavors
- 1 tablespoon fresh dill: Fresh dill makes such a difference here but dried works in a pinch
- 1 teaspoon sugar: Just enough to balance the tang from the vinegar and onion
- 1/2 teaspoon garlic powder: Distributes evenly throughout the dressing better than fresh garlic
- 1/2 teaspoon salt: Enhances all the other flavors
- 1/4 teaspoon freshly ground black pepper: Adds a subtle warmth that ties everything together
Instructions
- Prep your vegetables:
- Slice those cucumbers as thin as you can manage and do the same with your red onion, then toss them together in a large mixing bowl where they'll have room to mingle with the dressing later.
- Whisk up the dressing:
- In a separate bowl, combine the sour cream, mayonnaise, white wine vinegar, dill, sugar, garlic powder, salt, and pepper, whisking until everything is completely smooth and creamy.
- Bring it all together:
- Pour that gorgeous dressing over your cucumbers and onions, then gently fold everything together until every single slice is coated in that creamy goodness.
- Let the flavors marry:
- Pop the bowl in the fridge for at least 20 minutes, though honestly, an hour is even better if you have the time.
- Serve it up:
- Give it one last stir right before serving and maybe sprinkle a little extra fresh dill on top if you are feeling fancy.
My kids used to turn their noses up at anything with cucumber, but this salad completely changed their minds. Now they actually request it for summer barbecues, and watching them willingly eat vegetables feels like a parenting win I never expected.
Making It Ahead
This salad actually tastes better after it has had some time to hang out in the fridge. I have made it the night before a party, and the flavors just get more developed and wonderful. Just keep in mind that the cucumbers will soften slightly over time.
Customization Ideas
Sometimes I throw in some thinly sliced radishes when I want extra color and crunch. Greek yogurt can replace the sour cream if you want something lighter, and fresh parsley or chives can work instead of dill if that is what you have on hand.
Serving Suggestions
This salad is ridiculously versatile and somehow works with almost everything. It is the perfect cooling counterpart to spicy dishes, holds its own next to grilled meats, and makes any picnic spread feel complete.
- Pile it onto burgers or tacos for a creamy fresh element
- Serve alongside fish or chicken for a light complete meal
- Keep it simple and let it shine on its own as a refreshing side
There is something so satisfying about a dish that comes together quickly but still feels special enough for company. This cucumber salad has earned its permanent spot in my regular rotation, and I have a feeling it will find its way into yours too.
Recipe Questions & Answers
- → Can I make this cucumber salad ahead of time?
-
Yes, this salad actually benefits from chilling. Prepare it up to 24 hours in advance and store it refrigerated in an airtight container. The flavors will develop and meld beautifully overnight.
- → What can I use instead of sour cream?
-
Greek yogurt makes an excellent lighter substitute for sour cream. It provides similar tanginess and creaminess while reducing calories. Plain yogurt can also work, though it's slightly thinner.
- → Do I need to peel the cucumbers?
-
Peeling is optional. English or Persian cucumbers have thin, tender skins that don't need peeling. For standard garden cucumbers with thicker skin, peeling creates a more delicate texture.
- → How long does this salad keep in the refrigerator?
-
This cucumber salad stays fresh for 3-4 days when properly stored in a sealed container in the refrigerator. The cucumbers may release some water over time, so give it a quick stir before serving.
- → Can I add other vegetables to this salad?
-
Absolutely. Thinly sliced radishes add extra crunch and color. Bell peppers, cherry tomatoes, or even grated carrots work well. Just keep total vegetable quantities proportional to the dressing.
