Onam is Kerala's grandest festival celebrating the homecoming of the benevolent King Mahabali. In 2026, the ten-day festival begins on Atham (August 21, Friday) and culminates on Thiruvonam (September 2, Wednesday).

Whether you are in Kerala or part of the Malayali diaspora in the USA, UK, Canada, Gulf, or Singapore, Onam is a time to wear mundu and set saree, create vibrant pookalam (floral rangoli), enjoy a 26-dish Onam Sadhya, and reconnect with Kerala's rich culture.

The Story Behind Onam — King Mahabali

King Mahabali, a benevolent asura ruler, was so loved by his people that Kerala enjoyed a golden age of prosperity, equality, and dharma. Devas grew jealous; Lord Vishnu took the Vamana avatar (dwarf Brahmin) and asked Mahabali for three paces of land. As Vamana grew cosmic, two strides covered all worlds. For the third pace, Mahabali humbly offered his own head. Touched by his devotion, Vishnu granted him a boon: Mahabali could visit his people once every year — and that visit is Onam. Hence Kerala welcomes the just king home with pookalams, feasts, and celebrations.

Onam Sadhya — The 26-Dish Vegetarian Feast

Served on a fresh banana leaf in a specific arrangement, Onam Sadhya is one of the most elaborate vegetarian feasts in the world. Traditional dishes include:

  • Rice (matta rice or unakkalari)
  • Parippu (moong dal with ghee)
  • Sambar (Kerala-style with drumsticks)
  • Rasam (tangy tamarind broth)
  • Pulissery (yogurt curry)
  • Kalan (yogurt + raw plantain + yam)
  • Olan (white pumpkin + coconut milk)
  • Erissery (pumpkin + lentil)
  • Avial (mixed vegetables + coconut)
  • Thoran (cabbage / beans stir-fry)
  • Pachadi (sweet + sour yogurt)
  • Kichadi (cucumber yogurt)
  • Pickles + Achar (mango, lime, ginger)
  • Pappadam, Sharkara Varatti, Nendran Chips (crispy sides)
  • Payasam (Palada, Ada Pradhaman, Pal Payasam — sweet dishes)

Eating order: Start from the left side of the leaf with pickles, sides; then rice + parippu + ghee; then sambar + rasam; then desserts.

Pookalam Designs — Floral Rangoli

The pookalam grows day by day from a simple single-circle on Atham to an elaborate multi-tier design on Thiruvonam. Use these flowers:

  • Yellow: Chrysanthemum, marigold, sevanthi
  • Red: Hibiscus, rose petals
  • White: Jasmine, tuberose
  • Pink: Adenium, rose
  • Green: Banana leaves (border)
  • Orange: Marigold, kanakambaram
