This salad was never written down anywhere, and that was starting to worry me. My grandma just made it — a pinch of this, a glug of that, no measuring cup has ever been involved in her kitchen in her life — so one summer, a few years back now, I stood next to her at her counter with my phone open, typing like a court reporter while she worked, because I was not going to be the generation that lost this one. She thought it was hilarious. She also kept moving faster every time I looked down to type, which I maintain was deliberate.
And the funny thing is, it is barely a recipe at all. Cucumbers, a creamy dressing, dill, done. But I have never once taken this bowl to a barbecue and brought any of it home, and my neighbour across the street — the one who announced, in front of witnesses, that she does not like cucumber — ate two helpings of it last July and asked what was in it. Two. Possibly three; I lost count refilling the iced tea. This is the salad I make when the kitchen is too hot to think in, let alone cook.
Why You’ll Love This Recipe
- Fifteen minutes of actual work, and most of that is slicing. After that the fridge takes over and does the job in the cold like it was designed for exactly this, which, in August, it basically was.
- No cooking. None. The oven stays off, the stove stays off, nothing heats your kitchen up by a single degree. In a hot month that is not a small thing, that is the whole appeal standing right there.
- Nothing in it costs anything much or needs a special trip. Two cucumbers, sour cream, things from the door of the fridge. I have made this with the sad last cucumbers from the bottom of the crisper and it still worked.
- It genuinely improves as it sits. Most salads punish you for making them early; this one rewards you — an hour in the fridge and the slices have soaked up the dressing and calmed down and everything tastes more like itself.
- It goes with all of it. Grilled, fried, roasted, sticky, smoky — anything rich coming off a barbecue is better with something cold and sharp sitting next to it, and that is this bowl’s entire profession.
Ingredients
Short list, nothing precious. The cucumbers matter most. Pick them like you mean it — firm, heavy for their size, and squeeze the ends before one goes in the basket: soft ends, put it back. After that it’s a dressing you could whisk in your sleep.
- 2 large English cucumbers (about 1½ lb / 680 g), sliced thin — English ones, because the skin is thin and the seeds are basically not there; the garden kind gets its own moment in the FAQs
- ½ small red onion (about 60 g), sliced as thin as your knife allows — paper thin, that is the aim here
- ¾ cup sour cream (180 g), full fat if you can possibly manage it — the dressing section of my notes has this underlined twice
- 2 tablespoons white vinegar (30 ml), or apple cider vinegar if that’s the open bottle
- 1 tablespoon fresh lemon juice (15 ml)
- 1 tablespoon granulated sugar (12 g) — it sounds like a lot written down; it isn’t, it’s balance
- 1 teaspoon kosher salt (5 g) — that’s the dressing’s share; you’ll want roughly another teaspoon on top of that for salting the cucumber slices in step 2, and yes, both lots earn their place, I have tested the alternative
- ½ teaspoon black pepper (1 g) — fresh-ground if your grinder is where you left it, the ready-ground jar from the back of the cupboard if it isn’t; the salad forgives this one
- 2 tablespoons fresh dill (about 8 g), chopped, plus a little extra for scattering over the top at the end
- 1 small clove of garlic, grated — officially optional, in my kitchen it has never once been opted out of
How to Make It — Step by Step
- Cucumbers first — slice them thin, thinner than feels safe. ⅛ inch, call it 3 mm. The test is this: a slice should bend a bit when you pick it up. Bend, not break. If it falls apart in your fingers, you have gone too far the other way. A mandoline is the fastest way and I say this with love and one scar: those things bite, use the guard. A sharp knife and five patient minutes does exactly the same job. No peeling — English cucumber skin is thin and it’s half the crunch and most of the colour.
- Salt them and walk away. Do not skip this step — it IS the recipe. Toss all the slices with about a teaspoon of salt in a colander set over a bowl and leave them for 30 minutes. Go do anything else. When you come back there will be a puddle in that bowl that will genuinely surprise you — that puddle is the difference between this salad and cucumber soup, and it was inside your cucumbers the whole time, waiting.
- Slice the onion and tame it while the cucumbers drain. The red onion, sliced as thin as you can manage — see-through shavings if your knife hand allows it — goes into a bowl of cold water for 10 minutes. It takes the raw, eye-watering bite out and leaves the sweetness. My grandma never did this — she liked the bite, she was built different — but my kids staged a formal protest about raw onion in 2022 and the soak has been house law ever since. Drain it well.
- Whisk the dressing, and taste it NOW. Sour cream, vinegar, lemon juice, sugar, salt and pepper in a big bowl — big enough for the whole salad, save yourself washing a second one — whisked till it’s smooth, then the dill and garlic stirred in. Taste it at this point, on a cucumber-less spoon, and do not panic: it should taste a bit TOO tangy and a bit too salty on its own. That’s correct. The cucumbers are bland and watery by nature and they will calm the whole thing down to exactly where it should be.
- Squeeze the cucumbers dry. After their 30 minutes, take handfuls of the salted slices and squeeze them gently over the sink — or pile them into a clean tea towel and press — till they stop dripping freely. Gently is the word. You are not making jerky; you just want the loose water gone so it doesn’t end up in the dressing.
- Fold it all together. Cucumbers and drained onion into the dressing bowl, and fold — under, over, turn the bowl — till every slice looks coated. For about ten seconds it will look like far too much dressing. It settles. Trust the ten seconds.
- Chill it, at least an hour. Covered, in the fridge, 1 hour minimum, and up to 4 hours is honestly even better — the slices soften just a touch, go a little translucent at the edges, and drink the dressing in. One stir before it goes to the table and the extra dill scattered over the top, because grandma always said people eat the green flecks with their eyes first. She didn’t say that. I’m saying it. She just did it.
Tips for the Best Creamy Cucumber Salad
The salting step is the whole ballgame and I can prove it because I have skipped it exactly twice, both times in a rush, both times in front of guests, and both times I ended up tilting the bowl and spooning watery dressing off the top like it was a soup course nobody ordered. Thirty minutes. Colander. Every time. My mistakes were free; learn from them instead of paying for your own.
Full-fat sour cream — I will keep saying it. Low-fat sour cream is thinner to start with and it weeps in the fridge, separates, goes sad and watery around the edges of the bowl. Weep is an unkind word for a dairy product and it is also, unfortunately, the accurate one. Greek yoghurt does work in its place — tangier, brighter — just add a pinch more sugar to round it out.
Slice everything the same thickness, roughly. It sounds fussy and it isn’t about looks: a bowl with thick chunks and paper-thin slices mixed together eats unevenly — half the forkfuls crunchy, half limp — and you notice it on every bite without knowing why. Even slices, even salad.
And make it the day you serve it. That 1-to-4-hour chill is the sweet spot and after it, the clock is not your friend. I have served the day-two leftovers more than once and the flavour is honestly fine — it’s the crunch that’s gone, leaked away quietly overnight, and you’re left standing at the table describing to people how crisp it was yesterday, which is a sad little speech to give over a salad bowl.
Variations and Substitutions
Half sour cream, half mayonnaise. Richer, a little sweeter, very diner-salad-bar in the best way. This is my aunt’s version — the same aunt from the banana pudding wars — and I hate admitting she’s right about food because it encourages her, but she’s right about this one too.
The lighter bowl. Plain full-fat Greek yoghurt where the sour cream was, and a teaspoon of honey doing the sugar’s job — that’s the whole swap. Tangier, fresher-tasting, a different personality altogether — my sister calls this one the weekday version and asks for it by that name now.
Radishes, mint, shallots — the swap-ins. Radishes first: a handful, sliced thin. Crunch, plus a pink edge round the bowl. Looks like you tried much harder than you did. Fresh mint instead of dill sounds wrong on paper and is wonderful in the bowl — try it once before you judge it, I did. And if red onion is too strong for your crowd, shallots are the gentler cousin; or skip the onion completely and add a pinch of celery seed, which is my mother’s way, and she will tell you so at length.
What to Serve It With
This salad was basically invented to sit next to grilled food. Grilled chicken, burgers, kebabs, sticky ribs — anything rich, smoky or fatty that needs something cold and sharp beside it to cut through. That cutting-through is the job. It’s the whole job description.
It earns its place next to fried fish and roast chicken too. And on my brother’s cookout table it sits between the rolls and a bowl of buffalo chicken dip and honestly that spread needs nothing else. I have also eaten it standing at the open fridge with a fork at 11pm, which is not serving, exactly, but it is honest, and the bowl was nearly empty by then anyway.
How to Store It
In the fridge: a container with a lid that actually seals. Two days, tops. Flavour? Fine. Holds up, no complaints from me. The crunch is what goes — fades a bit more each day. That is just cucumber being cucumber. Nobody’s fault. Nothing to fix. Before you serve it again — stir it. Then pour off the water pooled at the bottom. There WILL be some. Drain it, and the dressing gets its dignity back.
In the freezer: don’t. I am not guessing about this. I froze a batch once, in a fit of organisation, and what came back out was mushy and strange in a way I still think about. Some things are not meant to be preserved. Eat it fresh, make it again next week — it takes fifteen minutes.
FAQs
Can I make creamy cucumber salad ahead of time?
Yes — and you should, within limits. Made 1 to 4 hours ahead, it chills properly and the flavours settle into each other and it’s better than the just-made version. A full day ahead is where the texture starts to pay for it. So here is what I tell people now. Sometime after lunch — no rush on you — put it together. Serve it that same evening, at dinner. A compliment comes? Take it. Straight face. The fridge did most of the work and you know it. Take it anyway.
Why is my cucumber salad watery?
Skipped salting. That is my answer nine times out of ten and I have stopped pretending it might be something more interesting. If the slices never got their half hour in the colander, the water had nowhere to go except later — into your finished salad, on the table, in front of the guests, while the dressing quietly turns to soup round the edges. A cucumber is basically water in a green jacket. Grandma had a ruder way of putting it. She was right, too. Salt first, though, and the puddle happens in the colander. Where you can throw it away. Not in the bowl. Never in the bowl — the bowl is where you have to serve it. Already made it and already watching it weep? Tip off what liquid you can without losing your temper — I have lost mine, it does not help the salad — stir a heaped spoonful of fresh sour cream back through to give the dressing its body back, and serve it sooner. Not later. Sooner.
Do I need to peel the cucumbers?
English cucumbers, no — thin, tender skin, it stays, it’s half the crunch. Regular garden cucumbers are a different animal: thick, waxy skin that tastes bitter, so peel those, and while you’re in there, scoop out the big seedy middle with a spoon or the salad will water itself down from the inside.
Can I use dried dill instead of fresh?
You can — about 2 teaspoons of dried dill in place of the fresh tablespoons. The flavour lands a bit flatter, a bit more hayloft than garden, but on a Tuesday night with no fresh dill in the house nobody is complaining, including me. Just do not leave the herb out and think it will pass. It will not pass. Cucumbers in plain cream with nothing green running through them — I have been served that bowl, at a house I will not name, and it is a sad, pale apology for this salad. Grandma measured nothing in her life, not once, and even she never sent it out like that.
How thin should I slice the cucumbers?
An eighth of an inch. Call it 3 millimetres. I arrived at that number the slow way — too thick one summer, tissue paper the next — and now I do not measure at all, I just know what the slice should feel like bending between my fingers. The ruler in our house belongs to my daughter’s homework and it has measured more cucumbers than geometry, whatever her teacher thinks. Thin enough that the dressing can get into the slice a little; thick enough that the slice still has a bite and a backbone. Go see-through thin — the mandoline show-offs know who they are — and the slices go limp in the dressing within the hour.
Nutrition
Per serving — call it ¾ cup, with the batch making 6 servings — the numbers come out friendly: somewhere around 85 calories, 6 g fat, 6 g carbohydrates, 1 g fibre, 4 g sugar and 2 g protein, give or take whichever spoon of dressing follows you to the table. Those are worked out from standard ingredient values, at my kitchen table, with a pencil — your sour cream brand and how much dressing actually ends up clinging to the slices instead of staying behind in the bowl will move them around a bit, and that’s fine. For a side dish that tastes like somebody’s grandma made it, those are friendly numbers.
Make it this week. Salt the cucumbers — that part, please, do not skip — and if it shows up at your barbecue and somebody asks for the recipe, you’ll understand exactly why my grandma never wrote it down. It was never a recipe to her. It was just what cucumbers were for.
