Kaanam Vittum Onam Unnanam: There's a popular Malayalam saying that loosely translates to: "One must have the Onam feast (Onasadya), even if it means selling one's property." While no one is likely to be doing that in Kerala-or even in Chennai, this Onam, it emphasises the importance of the Onam Sadya, the traditional, elaborate banana-leaf meal that is one of the highlights of the week-long festivities. Onam is Kerala's most significant festival and commemorates the homecoming of the legendary king Mahabali.

Chennai is Onam Ready
The build-up for Onam starts in Chennai well before the actual festival, which culminates with Thiruvonam on September 5, 2025. The city's standalone restaurants and luxury hotels vie with each other to serve the grandest Onasadya. Just like other metros across India, the appeal of Onam has widened with the big, festive Onam lunch becoming an integral part of social calendars. It's not just dine-in, either-many Chennaites are opting for takeaway sadyas or Sadya-in-a-box options. In most cities in Kerala, it's common for households to 'outsource' their sadya from traditional wedding cooks or caterers, a trend now adopted in other Indian metros too.
The Onasadya - A Time-Tested Culinary Tradition
The Sadya, a traditional, elaborate banana-leaf meal, is the highlight of festivals like Onam and Vishu, and weddings across Kerala. Dishes are served from left to right on the leaf: the top half reserved for accompaniments and the bottom half for staples and mains-similar to most South Indian banana-leaf meals. While it's almost always vegetarian, in some parts of northern Kerala it's not unusual to encounter sadyas that also include meat and seafood.
From puli inji to Kerala chips like the sweet chakkara upperi- a scrumptious variant coated with jaggery and spices-and thoran (stir-fried vegetables), the sadya offers a host of accompaniments. Most sadyas include kaalan, olan, vegetable stew, erissery, kootu curry (a mix of vegetables and Bengal gram), the fluffy Kerala papadam, along with pachadi and kichadi. Rice, almost always the par-boiled Kerala variety, is served first with dal and ghee, followed by sambar, rasam, and thick buttermilk towards the end of the meal. The crowning glory of the sadya, however, is the payasam.
This year, Chennai offers a wide array of Onam Sadya options:
