Sri Lankan Potato Curry
Sri Lankan Potato Curry (Ala Curry) is a rice and curry staple. Tender potatoes cooked in a creamy coconut base and mildly spiced. It’s simple and so good. Tempering is optional, but it adds a whole extra layer of flavour that’s hard to say no to.
I’ve been making this potato curry my whole life – it’s one of the first curries I learned to cook, and one I still make for my family now.
When it comes to Sri Lankan cooking, I just eyeball the ingredients. There’s no set rule here, especially with the spices and coconut milk. The measurements I’ve given you are a guide – adjust to your taste and you really can’t go wrong.
If you’re new to Sri Lankan cooking or just trying to nail a reliable ala curry that tastes like something your Lankan aunty would make – this is the one.
What Is Sri Lankan Potato Curry?
This is a classic Sri Lankan “white curry” (as opposed to a roasted curry powder base) like the red lentil dal(parippu). The potatoes are cooked slowly in thin coconut milk with aromatics like curry leaves, rampe, fenugreek, and a little garlic. Then finished with a pour of rich thick coconut milk that makes the whole thing incredibly creamy.
It’s a staple of the rice and curry spread, but honestly, it goes just as well with idiyappa, crusty bread, or even roti. It’s that versatile.
You can make it mild enough for kids, or turn up the chilli a notch for a bit more kick. Tempering is optional for everyday cooking, but if you’re making this for a special occasion or just want that extra layer of flavour, don’t skip it.
Ingredient Notes
Here’s what you’ll need. No quantities in this section. Check the recipe card below for exact amounts.
- Potatoes – Medium-sized ones work best. Peel and cut into quarters so they cook evenly.
- Onion – Sliced thin. Adds sweetness and body to the base.
- Curry leaves – A whole sprig. These are non-negotiable in Sri Lankan cooking. Dried ones work in a pinch but fresh is so much better.
- Rampe (pandan leaf) – Just one piece. Gives that signature warm, slightly floral note you can’t quite put your finger on.
- Fenugreek seeds – Just a little. They add a subtle bitterness that balances out the coconut milk beautifully.
- Garlic – Sliced, not crushed. You want it to melt into the curry gently.
- Tomato – Half a small roma tomato. Some people leave this out entirely, and that’s fine too. I use just a little bit for a hint of brightness – not enough to make it sour, just enough to round out the flavour.
- Raw curry powder – This is the mild, unroasted kind. Gives a hint of spice. It’s easy to make it at home. Use cumin and coriander powder instead.
- Chilli powder – Adjust based on who’s eating. Cut it right back for kids, or add more if you like heat.
- Turmeric – Gives that gorgeous golden colour and a mild earthiness.
- Canned coconut milk – This does double duty. Diluted with hot water for the thin coconut milk to cook the potatoes, and used as-is (thick) to finish the curry. One can covers you for both.

- Step 1: Peel your potatoes and cut them into quarters. Try to keep the pieces roughly the same size so they cook evenly.
- Step 2: Add the potatoes, sliced onion, curry leaves, rampe, fenugreek seeds, sliced garlic, chopped tomato, raw curry powder, chilli powder, turmeric, and salt into your pot. Give it a quick mix to coat everything in the spices.
- Step 3: Add 1/4 cup of your canned coconut milk to 1 cup of hot water. Stir to combine. This is your thin coconut milk.
- Step 4: Pour the thin coconut milk into the pot with your potato mixture. Place it on the stove and bring it to a gentle boil – not a rolling boil, just until you start to see the edges bubbling. Cover with a lid and cook on medium heat for 12 to 15 minutes, or until the potatoes are fork-tender. Check at the 12-minute mark.
- Step 5: Once the potatoes are cooked through, add your thick coconut milk (about 3 tablespoons of coconut milk mixed with a small splash of hot water). Stir gently and let it cook for another minute or two on low heat. You don’t want to boil it hard at this stage or the coconut milk can split.
- Step 6: Remove from heat and serve warm. That’s it!
Recipe Tips
- Add tempering for special occasions. Heat a little oil in a small pan, add sliced onion, dried red chilli, curry leaves, and a few mustard seeds. Let them sizzle until fragrant and golden, then pour the whole thing over the finished curry. It adds so much depth and makes it feel a little more dressed up.
- Don’t stir too much while cooking. Potatoes can break apart if you’re constantly stirring. Let them do their thing with the lid on.
Serving Suggestions
This curry is made for a rice and curry spread. Serve it with steamed white rice, idiyappa (string hoppers), or pol roti – it goes with all of them. Honestly, it’s good scooped up with a slice of crusty bread too.
Round out your plate with a bowl of spicy curries like chicken curry, beef curry or fish curry. And the rice and curry bowl won’t be complete with vegetable curries like beetroot, green bean or pumpkin curry and a generous spoonful of pol sambol on the side. That’s a proper Sri Lankan meal right there.
FAQs
Can I use fresh coconut milk?
Yes, absolutely! If you have access to freshly pressed coconut milk, use it. Just follow the same thin and thick split – dilute some for cooking, keep the rest thick for finishing.
What if I don’t have rampe or curry leaves?
The curry will still taste good, but those two aromatics are really what give it that authentic Sri Lankan flavour. Try to find them at your local Asian or Sri Lankan grocery store. They freeze really well too, so grab a big bunch and freeze what you don’t use.
Can I make this ahead of time?
Yes! In fact it tastes even better the next day once the flavours have had time to settle. Store it in an airtight container in the fridge for up to 3 days. Reheat in the microwave or gently on the stove with a splash of water or coconut milk.
Can I add any other vegetables?
This is a classic potato curry so I usually keep it simple, but you could add a handful of green beans or a small carrot cut into chunks if you like. Just make sure everything is cut to a similar size so it all cooks at the same time.
