Dad’s Creamy Cucumber Salad is the cool, tangy kind of side dish I reach for when the rest of the meal is warm, grilled, or rich. The dressing is simple—mayonnaise, vinegar, a little sugar, dill, garlic powder, and black pepper—but the texture depends on one important step: getting excess water out of the cucumbers before the dressing goes on.
My biggest recommendation with this recipe is not to rush the salting and draining. Cucumbers hold a lot of water. If we skip that step, the dressing can turn thin and watery after the salad sits in the refrigerator. Give the cucumbers time to release moisture first, and the finished salad stays creamy instead of soupy.
The Step That Makes the Biggest Difference
Salt draws moisture out of sliced cucumbers. In this recipe, the cucumber and onion sit with sea salt for about 30 minutes, then drain for another 30 minutes.
I would keep both stages. The first rest pulls water to the surface. The draining time gives that liquid somewhere to go before we add the mayonnaise dressing.
Do not squeeze the cucumbers aggressively. We want them drained, not crushed. A gentle stir in the colander once or twice is enough.
Ingredients
- 2 large cucumbers, peeled and thinly sliced
- 1 sweet onion, thinly sliced
- 1 tablespoon sea salt
- 1 1/2 cups mayonnaise, or more to taste
- 2 tablespoons vinegar
- 1 tablespoon white sugar
- 1 teaspoon dried dill weed
- 1 teaspoon garlic powder
- 1 teaspoon ground black pepper
How I Build the Creamy Dressing
The dressing should taste tangy, lightly sweet, and well seasoned before it touches the cucumbers. I recommend whisking the mayonnaise, vinegar, sugar, dill, garlic powder, and black pepper in a separate bowl until completely smooth.
Taste it at this stage. The salad has already been salted, so I would not add more salt automatically. The cucumber mixture may carry enough seasoning into the dressing on its own.
If you prefer a sharper salad, add a small splash more vinegar. If you like it slightly sweeter, add a little more sugar. Make those changes before combining everything so the dressing stays evenly mixed.
How to Make Dad’s Creamy Cucumber Salad
- Add the thinly sliced cucumbers, sweet onion, and sea salt to a large bowl. Toss gently to distribute the salt.
- Cover and let the mixture sit for 30 minutes.
- Transfer the cucumbers and onion to a colander set over a bowl or in the sink. Let them drain for another 30 minutes, stirring gently once or twice.
- Move the drained vegetables to a clean large bowl.
- In a separate bowl, whisk together the mayonnaise, vinegar, sugar, dill, garlic powder, and black pepper until smooth.
- Pour the dressing over the cucumber mixture and fold gently until every slice is coated.
- Cover and refrigerate for at least 2 hours before serving.
Why the Two-Hour Chill Matters
This salad tastes better cold, but chilling does more than lower the temperature. It gives the dill, vinegar, onion, and garlic time to season the dressing evenly.
I recommend at least 2 hours. If you taste it immediately after mixing, the dressing can seem a little separate from the vegetables. After chilling, everything tastes more settled and cohesive.
How to Keep the Salad From Turning Watery
Even after draining, cucumbers will continue to release some moisture. That is normal. A few habits help keep the texture creamy:
- Slice the cucumbers evenly so they drain at roughly the same rate.
- Do not skip the salting period.
- Give the vegetables the full draining time.
- Use a clean bowl after draining instead of mixing the dressing into the bowl that collected cucumber liquid.
- Keep the salad refrigerated until serving.
Make-Ahead Timing
This is a good make-ahead side because it needs refrigerator time anyway. My preferred window would be a few hours before the meal.
You can also prepare it the night before, but expect the cucumbers to soften slightly and the dressing to loosen as more liquid comes out. Give the salad a gentle stir before serving.
What to Serve With Creamy Cucumber Salad
I would pair this with grilled chicken, burgers, barbecue, baked ham, pork chops, sandwiches, or a simple summer dinner. The cold, creamy dressing is especially useful next to smoky or salty food.
If you want the same cucumber-onion idea without a creamy dressing, try my Marinated Cucumbers, Onions, and Tomatoes. That version uses a light sweet-tangy vinegar marinade with tomatoes instead of mayonnaise.

Simple Variations
Use red onion: Red onion gives the salad a sharper flavor and more color. Slice it very thinly.
Add fresh dill: If you have fresh dill, it can replace the dried dill. I would start modestly and add more to taste because fresh dill can become dominant quickly.
Leave some cucumber peel on: Thin-skinned cucumbers do not have to be completely peeled. Leaving narrow strips of peel adds color and a little extra texture.
Storage
Keep the salad covered in the refrigerator. For the best texture, I recommend eating it within 2 to 3 days.
If liquid collects at the bottom, stir gently before serving. I would not drain it aggressively because some of the seasoning is in that liquid too.
Frequently Asked Questions
Why do I need to salt the cucumbers first?
Salt draws out excess water. That helps prevent the mayonnaise dressing from becoming too thin as the salad sits.
Can I use English cucumbers?
Yes. English cucumbers have thinner skin and fewer large seeds, so they work very well. You may not need to peel them.
Can I use regular onion instead of sweet onion?
Yes. White, yellow, or red onion will work. I recommend slicing stronger onions very thinly so they do not overpower the cucumber.
Can I make this without sugar?
You can reduce or omit it, but the dressing will taste sharper. The small amount of sugar is there mainly to balance the vinegar.
Why did my dressing get runny overnight?
Cucumbers continue releasing water after the salad is mixed. Proper salting and draining reduces that problem, but some thinning is normal after a long rest.
