Kachumber is a no-cook Indian salad of cucumber, tomato, and red onion, seasoned with roasted cumin, lemon juice, and a little green chili. It comes together in 15 minutes and makes a genuinely useful side dish — the kind that cools down a spicy meal and doesn’t compete with anything else on the table. If you’re feeding a group, it scales easily and requires zero reheating or last-minute fuss.
Before you start
Two things make a real difference here. First, soak the chopped red onion in cold water for 10 minutes before adding it to the bowl. Raw onion straight from the cutting board can overpower everything else; soaking pulls out the sharpness so the onion adds flavor without heat. Second, use roasted cumin powder rather than plain ground cumin — the roasting gives it a slightly smoky, deeper taste that plain cumin doesn’t have. You can buy it pre-roasted, or make your own by dry-toasting whole cumin seeds in a pan for a couple of minutes and grinding them once cool. Skip the garnish — not worth the extra dish.
Leftovers and make-ahead
Kachumber is best eaten within about 30 minutes of dressing it, because the salt and lemon juice draw water out of the cucumber and tomato fairly quickly. If you’re making it ahead for a party or meal prep, chop all the vegetables and store them together in an airtight container in the fridge for up to 24 hours — but hold the salt, cumin, and lemon juice until right before serving. Once dressed, leftovers keep for up to one day in the fridge, though the texture will be softer and the bowl will have liquid in the bottom; just drain it and give it a quick toss. This salad does not freeze.
Mistakes to avoid
- Cutting the pieces too large: Uneven or chunky dice means some bites are all onion, others all cucumber. Aim for a consistent small dice — roughly the same size across all three vegetables — so every forkful has a bit of everything.
- Using underripe or watery tomatoes: A pale, hard tomato adds almost nothing here. Roma or heirloom tomatoes that are fully ripe give you the sweetness and slight acidity the salad needs. If your tomatoes are very watery, seed them before dicing to prevent a soggy bowl.
- Adding lemon juice too far in advance: The acid starts breaking down the vegetables immediately. If you’re doubling or tripling the recipe for guests, dress it in batches just before people start eating rather than all at once.
- Over-salting early: Salt pulls moisture fast. Season, toss, taste, and serve — don’t let it sit salted on the counter while you finish cooking everything else.
- Skipping the cumin entirely: It might seem optional, but roasted cumin is what gives this salad its savory backbone. Without it, the dish tastes flat and underdeveloped despite the fresh vegetables.

Common questions
Can I make kachumber salad a few hours before guests arrive?
Yes, but prep and dress separately. Chop all the vegetables up to 24 hours ahead and refrigerate them undressed in a covered bowl. Add the salt, cumin powder, and lemon juice no more than 20–30 minutes before you plan to serve, so the vegetables stay crisp and the bowl doesn’t fill with liquid.
What can I use instead of green chili if I want no heat at all?
Leave it out completely — the salad works fine without it. If you still want a little color and crunch in its place, finely diced green bell pepper is a good swap and adds a mild sweetness.
How do I scale this up for a large group without it getting watery?
Multiply the vegetables freely, but hold back on the salt until just before serving. For a crowd, consider seeding the tomatoes and lightly salting the cucumber in a colander for 10 minutes, then patting dry before mixing — this removes excess moisture before it ends up in the bowl.
Where do I find roasted cumin powder, and can I substitute regular ground cumin?
Roasted cumin powder is sold in most Indian grocery stores and many general supermarkets in the spice aisle. Regular ground cumin works in a pinch, but the flavor is noticeably milder and less complex — if you only have plain ground cumin, toast a small amount in a dry pan for 60 seconds before using it.
What main dishes does kachumber go well with?
It pairs best alongside anything spiced or rich — dal, chicken curry, grilled meats, or a spread of Indian flatbreads. It also works as a fresh topping stuffed into wraps or served next to simple grilled fish when you want something light and acidic on the plate.
