This is a no-cook salad built around smoked trout, thinly sliced English cucumber, capers, and a creamy dill dressing made from Greek yogurt, mayo, Dijon, and lemon juice. It takes 15 minutes start to finish and serves four. The honest reason to make it: it holds up well on a spread, scales easily, and the smoked fish does most of the flavor work for you.
Before you start
The two things that actually matter here are how thin you slice the cucumber and how you handle the dressing. Cucumber sliced too thick stays crunchy in a way that fights the flaked fish rather than complementing it — aim for about 1/8 inch, which a mandoline handles in under two minutes if you’re making a double or triple batch. For the dressing, whisk it in a separate bowl first and taste it before it touches anything else. The balance of lemon, mustard, and honey shifts depending on your yogurt brand and how salty your capers are, so adjust now rather than after everything is dressed and you can’t fix it.
Mistakes to avoid
- Dressing the salad too far ahead. The cucumber releases water quickly once dressed, which thins the dressing and makes the whole thing watery. If you’re prepping for guests, keep the dressing separate and toss it together no more than 15 minutes before serving.
- Using cold, straight-from-the-fridge smoked trout. Cold fish is firmer and harder to flake cleanly. Pull it out 10 minutes before you start so it breaks into nicer pieces without turning to mush.
- Adding too much dressing at once. This salad doesn’t need to be heavily coated. Start with about two-thirds of the dressing, toss, and add more only if it looks dry. Overdressed cucumber salad gets soggy fast.
- Skipping the rest time if you’re serving immediately. The recipe says 5–10 minutes to let flavors meld — that’s real. The garlic and dill need a few minutes to come through. Don’t skip it, especially if you’re serving this as a standalone dish rather than a side.
Smart swaps
Smoked trout is the ingredient most people won’t have on hand. Hot-smoked salmon works as a direct swap — same flaky texture, slightly richer flavor. Cold-smoked salmon is a different product; it’s silky rather than flaky and will change the texture of the salad, though the flavor is still good. Capers are worth tracking down rather than skipping — they add a briny punch that the dressing alone doesn’t replicate — but finely chopped cornichons are a reasonable stand-in if you’re stuck. Skip the garnish of extra dill fronds on top: not worth the extra prep when you’re scaling this up for a crowd.
Storage and reheating
Store leftovers in an airtight container in the fridge for up to 24 hours. After that, the cucumber softens significantly and the dressing thins out from the released liquid. There’s no reheating — this is a cold dish. If you’re making it ahead for a party, store the dressed salad and any extra dressing separately, and drain off any pooled liquid before serving. This does not freeze well; the cucumber texture breaks down completely.

Notes
Chef’s Tips:
- For extra crunch, add thinly sliced radishes or a handful of watercress.
- Swap Greek yogurt for sour cream for a tangier dressing.
- If you prefer a milder onion flavor, soak the red onion slices in cold water for 10 minutes before using.

Your questions, answered
Can I make this salad the night before?
You can prep all the components the night before, but don’t dress the salad until close to serving time. Store the sliced cucumber, onion, trout, dill, and capers together in one container and the dressing in a separate jar in the fridge — combine them 10–15 minutes before you eat.
How do I scale this up for a larger group?
The recipe doubles and triples cleanly. The one thing to watch is the dressing — scale it up proportionally but taste as you go, since a larger batch of yogurt can mute the lemon and mustard, and you may need a little extra of both to keep the flavor sharp.
Where do I find smoked trout, and what should I look for?
Most well-stocked grocery stores carry it near the smoked salmon in the refrigerated seafood section, often vacuum-packed in 4–6 oz portions. Look for hot-smoked trout, which is fully cooked and flaky — that’s what this recipe is built around.
Is full-fat Greek yogurt really necessary, or can I use low-fat?
Full-fat gives the dressing a thicker, creamier texture that clings to the cucumber rather than pooling at the bottom of the bowl. Low-fat works in a pinch but the dressing will be noticeably thinner and slightly more tart.
