Quick Summary
Onam 2026 marks another year of Kerala’s famous harvest festival, marked by cleaning yards and laying a ‘pookalam’ of yellow flowers on Atham, the first day of the festival, with more flowers added as the days pass. During this time, preparations for the famous boat races, attire, and arts are undertaken. On the last day of this festive period, or Thiruvonam, which falls on 26 August, families wear new clothes, make elaborate floral arrangements and indulge in the Onam Sadhya. All of this traces its roots back to the Thrikkakara Vamanamoorthy Temple in Ernakulam, near Kochi.
Deep Dive
The famous tale of King Mahabali is also associated with this temple, which is why Thrikkakara is treated as Onam's spiritual home. The temple has its own Onam Sadhya, cooked in its kitchens and served on Thiruvonam to over 20,000 devotees, considered the closest thing Kerala has to an OG version of the feast. Now, a little detour around the legend of why this festival exists, before diving into the Onam Sadhya. It has something to do with Lord Vishnu, the King and a legion of asuras or demons, threatening the cosmic balance.
The Sacred Foot and The Thrikkakara Temple
Before Onam, there was a tale of King Mahabali, an asura ruler, famous for his prosperity and fairness during his reign, but his subjects were power-hungry demigods and demons. So, to restore the balance, Aditi, the primordial mother of the Gods, prayed to Vishnu to return the heavens to the Gods or devas. In his quest, Lord Vishnu took the form of Vamana, a dwarf Brahmin, his fifth avatar. He asked King Mahabali for land measuring three steps. The proud king, despite warnings from his guru, who knew that it was Lord Vishnu himself.
Following this, Vamana grew to an enormous size, with one step covering the earth, the second covering the skies, and with no space left, the king voluntarily offered his head. Lord Vishnu pushed the King into the netherworld, or Patal, whilst granting him the wish of an annual visit to his former kingdom, restoring the rule of the Gods in heaven. Legend has it that this exchange took place where the Thrikkakkara Vamana Moorthy Temple stands today. The hint is in the name itself: ‘Thiru-kal-kara’ collectively means the place of the sacred foot.
Mythological side aside, there is historical evidence of carvings on the temple's sanctum walls depicting Onam celebrations dating back roughly 2,500 years, and temple inscriptions record the Chera kings, under Cheraman Perumal, convening month-long annual gatherings of local rulers and chieftains here, ending on Thiruvonam. When distant chieftains couldn't make the journey, the king reportedly ordered that Onam be celebrated in every household instead.
Thrikkakara Mahotsavam Builds Up To Onam 2026
The temple's festival, the Thrikkakara Onam Mahotsavam, opens with a flag-hoisting ceremony (kodiyettu) on Atham and runs for ten days. Each day, the deity is dressed as a different one of Vishnu's ten avatars (dashavatarachaarthu); the day the deity is dressed as Vamana (Vamanachaarthu) draws the largest crowds. A pookalam is laid at the temple daily and grows through the ten days. In 2026, the flag goes up on 16 August, and the festival builds to Uthradam on 25 August and Thiruvonam on 26 August, which is the day it closes with an arattu, the ceremonial bathing of the deity.
The Anayoottu Ritual
On Uthradam, the day before Thiruvonam, the temple's rituals begin with anayoottu, which is the ceremonial feeding of its elephants. This is followed by the Uthradasadya, a feast served to everyone who visits the temple that day. In the evening come valiyavilakku, the lighting of a large traditional lamp, and pallivetta, a symbolic hunt.
On Thiruvonam itself, the day starts before dawn with the arattu. It's followed by pakalpooram (also called seeveli), a procession in which the deity is carried on an elephant’s back, accompanied by seven to eight caparisoned elephants and a panchavadyam ensemble. Only after this procession does the temple begin serving the Onam Sadya, from around 10 am in its courtyard, to a crowd that now regularly crosses 20,000 people.
What's On the Onam Sadhya Served to Devotees
Onam special food at Thrikkakara follows the order most Onam Sadhyas use, with a few local specialities. Papadam is served first, followed by chips made from raw plantain, yam, long beans, brinjal and bitter gourd, and pazham nurukku (banana pieces). Salted vegetable preserves and mango and lime pickles come next, alongside parippu (a lentil curry finished with ghee) and sambar. The curry course is where the Sadhya's coconut-based cooking shows up in full swing:
Erissery: a slow-cooked pumpkin-and-cowpea curry tempered with roasted coconut.
Kalan: a thick yoghurt-and-yam curry.
Olan: a lighter curry with ash gourd cooked in a coconut milk stew, consumed to offset the heavier dishes around it.
Avial (aviyal): a mixed vegetables dish, cooked in a coarse coconut-yoghurt paste and finished with raw coconut oil.
Pachadi: a raita equivalent in the Onam Sadhya banana leaf, coming in pineapple, beetroot and cucumber variations.
Kichadi: quite similar to the pachadi, it has a vegetable or fruit cooked with yoghurt and coconut, with a sharper flavour.
Injithairu: Thrikkakara's own speciality, this dish is a ginger-curd relish locals describe as carrying the weight of a hundred curries on its own.
Puli inji: served alongside injithairu, this dish is a sweet-sour-hot condiment with ginger, tamarind and jaggery.
The meal concludes with rasam and a generous serving of palada pradhaman, a milk-and-rice payasam finished with dried fruit and cashews.
What's Offered to the Deities Before the Devotees Eat
Before any devotee is served, the Sadhya is first offered as naivedyam, or bhog, to Thrikkakarayappan (Vamana) in the sanctum. A local custom adds a second step: after the main offering, a portion of the naivedyam is set aside for a smaller roadside shrine associated with an old village legend, a practice that devotees at Thrikkakara still observe today.
Families replicate a version of this at home on Thiruvonam evening. Lamps are lit, and a portion of the Onam Sadhya is set out for Mahabali and the family's ancestors before the meal is served to everyone else, usually by the eldest member of the household.

The OG Kerala Festive Feast
It all starts with a story, and this one is of homecoming, the sacrifice of a benevolent king who offered his head to a deity’s avatar when the heavens and earth were not enough. Goodness is always celebrated, and the tale finds its manifestation in the Onam Sadhya, with a massive spread of Kerala dishes ranging from fried banana chips and chutneys to coconut curries.
