Polish Cucumber, Tomato and Onion Salad Recipe
Polish cucumber, tomato and onion salad is a classic side for summer dinners, when vegetables are ripe and sun-kissed. Crunchy cucumber, juicy tomato and thin onion feathers come together in a slightly sour, gently sweet dressing made with oil and vinegar. This version is quick, very juicy and really lifts the flavor of simple home-style dishes.
This is one of the most typical home-style “dinner” salads in Poland, often served alongside potatoes and meat instead of cabbage slaw. During cucumber-and-tomato season it appears on tables almost every day, usually made without a strict recipe, just by eye.
This version focuses on balancing the acidity of the vinegar with the natural sweetness of ripe tomatoes. Thanks to the use of neutral oil, the vegetable flavor stays clear and the salad pairs well both with meat and with a simple sandwich. It’s a typically Polish answer to Greek-style salads, but lighter and juicier.
Why this version works
- Lightly salting the vegetables first draws out their juices and intensifies the flavor of the simple dressing.
- Thinly sliced and, if needed, softened onion adds character without overpowering the salad.
- Neutral oil doesn’t mask the taste of the vegetables, so the salad pairs well with many Polish dishes.
Chef's tips
If you’re using very juicy beefsteak-style tomatoes, you can remove some of the watery core – otherwise too much juice will collect at the bottom., Keep an eye on the amount of juice: there should be enough to scoop up with a spoon, but the vegetables shouldn’t be floating in it like in broth., For larger grill gatherings I often make the dressing separately and pour it over just before serving so the cucumbers stay crunchy.
How to serve
Serve with boiled potatoes with dill and pork chops, meat patties or fried eggs – it brightens the whole plate., It also works very well as a quick salad for a barbecue or as a side to cottage cheese sandwiches; use any extra juice to drizzle over bread or roasted vegetables.
Watch out for
- Don’t mix too vigorously – the tomatoes will quickly break down and the dressing will turn into mush.
- Don’t make the salad many hours in advance, as the cucumbers will lose their crunch and become rubbery.
Substitutions
- Instead of spirit vinegar, use apple cider vinegar for a milder, more fruity taste.
- If you don’t like raw onion, replace it with spring onion or just chives.
- You can swap part of the neutral oil for olive oil if you’d like a gentle Mediterranean note.
Ingredients
- fresh cucumber - 2 piece
- tomatoes - 3 pieces
- onion red or white - 0.5 piece
- oil rapeseed or sunflower - 2 tablespoons
- vinegar apple or 10% spirit vinegar - 1 tablespoon
- sugar - 0.5 teaspoons
- salt
- pepper ground black
- parsley or dill - 0.25 bunch
Preparation
- Wash and dry the cucumbers. If the skin is thick or bitter, peel them thinly. Slice into half-moons about 3–4 mm thick so they stay crunchy after mixing and don’t go limp.
- Wash the tomatoes, remove the hard cores and cut into larger cubes or wedges, each one or two bites. The pieces should hold their shape but release juice when gently pressed.
- Peel the onion and slice into very thin feathers. If it’s sharp, cover with cold water or water with a splash of vinegar for 5 minutes, then drain thoroughly – this will make it milder and less pungent.
- In a larger bowl, combine the cucumbers and tomatoes, sprinkle lightly with salt, mix gently and set aside for 5–10 minutes. A thin layer of vegetable juice should start to collect at the bottom, but not a full puddle.
- In a small bowl, mix the oil, vinegar, sugar, a pinch of salt and pepper. Stir until the sugar dissolves and the dressing is uniform, slightly cloudy and clearly sweet-and-sour in taste.
- Rinse the parsley or dill, dry very well (for example in a kitchen towel) and chop finely. The herbs should be dry so they don’t water down the dressing or clump together.
- Add the drained onion to the bowl with the vegetables. Pour over the dressing and very gently mix with a spoon or your hand until the pieces are evenly coated but still intact, without crushing the tomatoes.
- Sprinkle the salad with chopped parsley or dill. Taste and, if needed, adjust with more salt, pepper or a little extra vinegar. Serve right away or after 15–20 minutes of light chilling, when the dressing has thickened slightly with the vegetable juices.
Storage
The salad is best on the day it’s made, when the cucumbers are crisp and the tomatoes hold their shape. It will keep in the fridge until the next day, but the vegetables will soften and the dressing will become more watery and milder.
When I make this salad for a family dinner, I always prepare a double batch – someone will end up eating the dressing with a spoon straight from the bottom of the bowl.
