This olan recipe is a light, mild Kerala curry made with ash gourd and cooked black-eyed peas, simmered in coconut milk. It is often called the mildest dish on the entire Onam Sadya banana leaf.
I make this whenever I want something simple that still feels like a proper part of the meal.
(step-by-step-recipe-video-below)
What is Olan?
This olan recipe kerala style is a stew made by cooking ash gourd and black-eyed peas in coconut milk. It has just a light tempering of coconut oil and curry leaves, and is meant to be gentle in flavor, not bold.
On the Onam Sadya banana leaf, olan sits between spicier, tangier dishes. Its whole job is to be the quiet pause between them, not the star of the meal.
Regional Variations of Olan
Even a dish this simple changes a little depending on which part of Kerala it comes from.
Central Travancore Style: This Central Travancore version of olan leans on a generous amount of coconut milk. It comes out richer and creamier than other regional versions.
Palakkad Style: An olan recipe palakkad style keeps things simple. It uses fewer ingredients and leans harder on the natural sweetness of the ash gourd itself.
Malabar Olan: In parts of northern Kerala, a malabar olan recipe sometimes adds pumpkin alongside or instead of ash gourd. This gives it a slightly sweeter, softer texture.
This is based on my own research across food blogs, recipe sites, and publicly available sources. If you are from any of these regions and something reads differently from what you know, I would love to hear from you in the comments.
Preparation Tips for Best Results
Olan is simple, but a few habits keep it from turning bland or watery.
Cook the peas separately first. Black-eyed peas need to be soft and tender before they go into the curry, so pressure cook or boil them ahead of time.
Cook the ash gourd in thin coconut milk, not water. This is what gives olan its flavor from the very first step, instead of relying only on the thick milk added later.
Troubleshooting: if your olan tastes watery or thin. This usually means not enough thick coconut milk went in at the end, or it simmered too long and lost its richness. Add thick coconut milk generously and only simmer briefly after.
Keep the chili optional and light. Olan is meant to be the mild dish on the leaf, so if you use chili at all, one or two is usually enough.
Add the thick coconut milk last, and only for a minute or two. Boiling thick coconut milk for too long can make it split, the same mistake that ruins a lot of coconut-based curries.
Why This Olan Recipe Works
This recipe works because it doesn’t try to be more than it is meant to be.
Cooking ash gourd in coconut milk builds flavor early. Using thin coconut milk instead of water from the very start means the vegetable actually absorbs flavor as it cooks.
The tempering is kept minimal. Just mustard seeds, coconut oil, and curry leaves are enough, since olan isn’t meant to carry a long spice list.
It only simmers briefly once the thick milk goes in. This keeps the coconut milk from splitting and keeps the texture smooth and creamy.
It earns its place by contrast. Next to spicier, tangier Sadya dishes, olan’s restraint is exactly what makes the whole meal feel balanced.
What Olan Taught Me About the Quiet Dishes
At my first Onam Sadya, I remember being amazed by just how much food was on that one banana leaf. Thirty, maybe thirty two, separate items, each one demanding attention in its own way.
Olan was easy to overlook in the middle of all that. It doesn’t announce itself the way a tangy pickle or a peppery rasam does.
But I noticed that every time I came back to the leaf, I kept returning to a spoonful of olan between the bolder dishes. It gave my palate somewhere quiet to rest before the next flavor.
That is when I understood that not every dish on a table needs to be the loudest one. Sometimes the quiet dish is the one doing the most work, just not the kind of work anyone notices right away.
Serving Suggestions for Olan
Olan is traditionally served on a banana leaf with rice, alongside spicier Sadya dishes like sambar and kalan. On a regular day, it works well as a light side with plain rice and a simple dal.
A small drizzle of ghee over the rice pairs nicely with olan’s mild flavor.
How to Store Leftover Olan
Olan keeps in the fridge for about two days in an airtight container. Since it is coconut milk based, I would not recommend freezing it.
When reheating, warm it gently on low heat rather than letting it come to a hard boil, so the coconut milk doesn’t split.
Pro Tips for Perfect Olan
A few more details help olan turn out right every time.
Cut the ash gourd into even, medium-sized pieces. Pieces that are too small turn mushy, while pieces that are too large won’t cook through in time.
Use full-fat coconut milk, not a light version. Olan depends on the richness of the coconut milk, so a lighter version leaves it thin and less satisfying.
Season with salt early, not at the end. Adding salt while the ash gourd cooks lets the flavor settle in properly, instead of sitting on the surface.
Don’t skip the curry leaves in the tempering. They are a small addition, but they carry a lot of olan’s final aroma.
Time the tempering however works for you. Some cooks temper first and add the vegetables after, while others temper last like I do. Both methods work fine.
Taste before adding any chili. Since olan’s whole identity depends on staying mild, add chili slowly and taste as you go rather than committing to a set amount upfront.
Let it rest for a few minutes before serving. Olan thickens slightly as it sits, and the flavors settle together better once it’s off the heat.
Reserve the thick coconut milk separately while cooking. If you’re using canned coconut milk, keep the thin and thick portions apart from the start, so you can add each at the right stage.

Basic Ingredients Used to Make Olan
Ash Gourd: This is the main vegetable in olan, and it turns soft and slightly translucent as it cooks, soaking up the coconut milk’s flavor.
Black-Eyed Peas (Lobia): Cooked separately before going into the curry, these add texture and a bit of protein to an otherwise light dish.
Coconut Milk: Used in two stages, thin milk for cooking and thick milk for finishing, coconut milk is what gives olan its signature creaminess.
Green Chili (Optional): Olan is meant to stay mild, so chili is optional here. Use it sparingly if you want just a touch of warmth.
Coconut Oil and Curry Leaves: Used only in the tempering, these bring the last layer of flavor to a dish that otherwise stays very simple.
How to Make This Olan Recipe
Making olan comes down to three parts: cooking the ash gourd, adding the peas and thick coconut milk, and finishing with a tempering. Here is a quick overview before you scroll down to the full recipe card with exact measurements.
Cooking the Ash Gourd
Simmer the diced ash gourd in thin coconut milk with a little salt, until it is tender. This usually takes about ten minutes on a gentle simmer.
Adding the Peas and Thick Coconut Milk
Stir in the cooked black-eyed peas, then add the reserved thick coconut milk. Let it simmer for only one to two minutes, just enough to combine, then turn off the heat.
Finishing with Tempering
In a small pan, heat coconut oil and add mustard seeds and curry leaves until they sizzle. Pour this tempering over the olan just before serving.
The full recipe card with exact quantities, timings, and step-by-step instructions is right below.

Frequently Asked Questions about Olan Recipe Kerala Style
What is olan made of?
Olan is made from ash gourd and cooked black-eyed peas, simmered in coconut milk and finished with a light coconut oil and curry leaf tempering.
Why is olan considered the mildest Sadya dish?
It uses very few spices and relies mostly on coconut milk and the natural sweetness of the vegetables. Other dishes on the same banana leaf are spicier or tangier by comparison.
Can I make an olan recipe without coconut milk?
Coconut milk is central to olan’s flavor and texture, so it’s not really optional. If you have a coconut allergy, a mild nut milk like cashew or almond can work as a substitute, though the taste won’t be the same as traditional olan.
What is the difference between olan and erissery?
Olan is a lighter stew made with coconut milk. Erissery uses a ground coconut paste instead, often topped with roasted coconut for a nuttier flavor.
Why did my coconut milk split in the olan?
This usually happens from boiling the thick coconut milk for too long. Add it at the end and only simmer briefly, on low heat.
Can I use pumpkin instead of ash gourd?
Yes, pumpkin is a common substitute and is actually traditional in some Malabar-style versions of olan.
Is olan spicy?
No, olan is meant to be one of the mildest dishes in a Sadya. Chili is optional and should be used sparingly if at all.
Can I make olan vegan?
Yes, olan is naturally vegan already, since it relies on coconut milk rather than any dairy.
How long does olan stay fresh?
It keeps in the fridge for about two days in an airtight container. I would not recommend freezing it, since coconut milk based curries change texture once thawed.
My Recommended Product:
Kalan doesn’t need a huge amount of coconut, just a cup for the masala paste, but grating even that much by hand still takes a few minutes you could skip. For this recipe, I recommend the Brewine 2-in-1 Coconut Scraper & Citrus Juicer.
Since the coconut goes straight into a grinder to make the paste anyway, having it scraped quickly and evenly with the stainless steel blade means one less slow step before you’re on to actually cooking. It’s a small thing, but on a day when you’re making more than one Sadya dish, those saved minutes add up.
I only recommend products I’ve personally used or truly believe in for home cooking.
