Onion Thokku – Vengaya Thokku Recipe


This is an OPOS – One Pot One Shot recipe.
# This recipe works well ONLY in a 2 or 3 liter Indian style pressure cooker. Do not use a big cooker without adjusting the quantity. It wont work. Do not scale the recipe up or down. Use exact measurements and equipment.
Generally, making of thokku / thick chutney can be very laborious which includes sauteing the veggies in oil for not less than 30-40 minutes. Thokku made using OPOS just takes 5 minutes on the stove. You might think that pressure cooking might just steam the onion. “A paste of steamed onions with spices is the last thing you wanna eat. Its aghast.” But you are in for a surprise. There is a catch. We will not be adding any water while cooking. The onions are going to caramelize in its own juices in high heat for a short time. Believe me, this recipe is one of the best things that has happened to me in cooking.

I tried this recipe 3-4 times so far and the flavor has been phenomenal. If you are worried about burning the bottom of your pressure cooker, don’t be.
Hope you enjoy the video!

Enjoy your thokku with rice, idli, dosa etc…

  1. Hi sis !! How do I make this on gas stove ? Will it work the same way if I keep in stove top for 5 whistles? Please advice.
    BTW, thank you for all the recipes. I only use your website for most of the recipes.

  2. Tried this. Chutney was good. But I guess I added too much jaggery so it turned out sweet.
    I don’t use jaggery in spicy cooking so I put too much or the sweet taste was different for me. Going to try without that. Buy the Chutney was nice and different taste.
    Do u have quinoa recepies Indian style

  3. Hi Kannamma ,
