Vengaya Sambar, also known as Archavittu Sambar, is a classic onion sambar from Palakkad cuisine.This dish is made with small onions (shallots), toor dal, and a freshly ground coconut spice mix. Serve it with steaming rice and sautéed Indian potato curry for an authentic Tamil Brahmin meal.

Vengaya Sambar blends the rich flavors of Tamil and Kerala cooking. It pairs beautifully with rice or tiffin dishes like idli, dosa, ven pongal, onion uttapam and adai. Try this authentic recipe for a wholesome and comforting meal!
It’s a Sunday tradition at my inlaws to serve this chinna vengayam sambar with potato fry, making it a firm family favorite. The recipe’s unique ground spice mix, or “archavittu” in Tamil, gives this sambar its distinct taste, setting it apart from other sambars in Tamil cuisine. You can make instant sambar with homemade sambar powder.
Top Tips:
- Use freshly grated coconut or frozen grated coconut to best flavour. I don't recommend desiccated coconut. It change the flavours and is not recommendable.
- Use small onions (shallots) for a slightly sweet flavor.
- Adjust spice levels by adding more dried red chillies.
- Grind the spices fresh for the best aroma and taste.
- Thick consistency is key for this sambar—don’t let it become too watery.
- Serve it with rice, potato fry, or South Indian tiffin items like dosa or idli.
Serving Suggestions

Notes
altogether alter the flavour and is not recommendable.
You could use large onions, but the small onions ( shallots) renders a bit of sweet flavour .
Dried Chilli could be increased if you like it spicier. If you do not enjoy your sambar with a ting of
sweetness, reduce the jaggery further.

I can so relate to this! I'm from up north and my husband is Mangalorean. Sunday brunches at home used be poori-aloo ki sabji, samosas and jalebis while at Mangalore, we do fish curry and appams. I loooove both these just as much. And these days we try to do a mix of both. I love the fact that we are a part of both these cultures 🙂
