Aloo ko Achar Recipe: Nepali Potato Salad

Aloo ko achar (literally 'potato pickle') is not a pickle in the jarred, shelf-stable sense. It is a room-temperature potato salad, boiled potatoes tossed in a punchy dressing of roasted sesame, mustard oil, timur and lemon or vinegar.

You will see it at every Nepali picnic, every dashain spread, and every roadside cart selling sekuwa. It is the dish that convinces people who claim they don't like potatoes that they, in fact, love potatoes.

If you already know dal bhat, think of aloo ko achar as its loud, tangy cousin: same everyday Nepali kitchen, completely different personality. It also sits comfortably next to sukuti sadeko on a bhoj platter if you want to go all in on Nepali flavors.

This recipe serves 4 as a side dish. Everything spice-related here ships from our pickles & achar section and the spice aisle, so if your local store is out of timur, we're not.

4 medium potatoes (Yukon gold or any waxy potato), boiled and cubed. 2 tablespoons Nepali Brown Sesame (Khairo Til), dry roasted and ground coarse. 1/2 teaspoon Timur (Sichuan Pepper), toasted and crushed. 2 tablespoons Roasted Khokana Mustard Oil. 1/2 teaspoon Cumin Seeds, toasted and ground. 1/4 teaspoon Turmeric Powder.

Also: 1/2 teaspoon Crushed Red Chilli or to taste, juice of 1 lemon (or a splash of vinegar), 2 tablespoons chopped fresh cilantro, 2 tablespoons chopped green onion, 1-2 chopped green chilies, and salt to taste. If you want the deeper, funkier version some families make, a spoon of fermented gundruk stirred in is not unheard of.

1. Boil the potatoes whole, skin on, until a knife slides in easily but they aren't falling apart, about 15-20 minutes. Cool, peel, and cube into bite-size pieces.

2. Dry roast the sesame in a pan on low heat, shaking often, until it turns golden and starts popping. Let it cool, then grind coarsely in a mortar or spice grinder. Do not grind it to a paste, you want texture.

3. Toast the timur and cumin in the same dry pan for 30-60 seconds until fragrant, then crush both together. Timur is the real signature here: it gives that faint tingly, citrusy buzz on the tongue that makes this dish unmistakably Nepali.

4. Warm the mustard oil in a small pan until it just starts to shimmer (this softens its raw bite), then let it cool slightly.

5. In a big bowl, combine the cubed potatoes, ground sesame, crushed timur-cumin, turmeric, crushed red chilli, warmed mustard oil, lemon juice, cilantro, green onion and green chilies. Season with salt.

6. Toss gently so the potatoes stay intact but every cube gets coated. Taste and adjust: more lemon for tang, more chilli for heat, more sesame if you want it nuttier.

7. Let it sit at room temperature for at least 20-30 minutes before serving. Like most achar, it tastes better once the flavors have had a little time to settle in.

The whole dish rides on balance between fat (mustard oil), acid (lemon), heat (chilli) and that background hum from timur. Taste as you go and don't be shy with the lemon; Nepali achar skews tangier than most people expect on the first try.

Waxy potatoes hold their shape better than starchy russets, which tend to go mushy once tossed. If all you have on hand are russets, boil them slightly less than you think you need to.

If your timur smells faint or dusty, it has probably been sitting too long; fresh timur should have a sharp, almost floral, mildly numbing smell when you crush it between your fingers. It's worth buying it whole and grinding small batches yourself rather than pre-ground.

Curious how timur compares to actual Sichuan pepper used in Chinese cooking? Our timur guide breaks down where it fits into Nepali cooking and why it isn't quite the same thing.

You'll see this at dashain gatherings, at teej parties, alongside sel roti at any festival table, and honestly just as a Tuesday night side dish with plain rice. It's one of those dishes that doesn't wait for an occasion.

It pairs naturally with anything grilled or fried: sekuwa, fried fish, momo, or a simple dal bhat. If you're building out a full Nepali spread for dashain or tihar, aloo ko achar belongs on the table alongside the sweets and the sel roti.

For a wider tour of how achar fits into Nepali meals generally, our achar types guide compares this potato version to the fruit and vegetable achars most people know better outside Nepal.

Aloo ko achar keeps well in the fridge for 3-4 days in a sealed container. Actually, most people agree it tastes even better the next day once the potatoes have soaked up the dressing overnight.

Bring it back to room temperature before serving; cold mustard oil turns cloudy and dulls the flavor. A quick squeeze of fresh lemon right before serving perks it back up.

Don't freeze it. Boiled potatoes go grainy and watery once thawed, and there's no fixing that texture once it happens.
