Terrifically tangy and sour Tomato Rasam is a delicious soup-like dish that can be enjoyed over rice or on its own as a hearty soup. Here I share step-by-step instructions with photos for preparing this recipe two different ways, as a traditional classic tomato rasam (thakkali rasam) or try a spicier Andhra-style version of tomato charu.

About Tomato Rasam
Tomato rasam is a popular South Indian dish that is known for being equally healthful and delicious. In fact, it’s often served as a spiced hot drink that helps ease cold symptoms and digestion issues.
Tomato is called as “Thakkali” in Tamil language. So this delicious piquant rasam is also known as “Thakkali Rasam”.
It is a vegan recipe that features juicy tomatoes, bold spices, and lots of ginger and garlic for an extra pungent, wonderfully tangy flavor.
While there are many different recipes for making a traditional tomato rasam recipe – this is by far the easiest to make from scratch. And, in my opinion, it is the tastiest, too!
There are no dal/lentils used in this tomato rasam recipe. Also, there is no tamarind added and you don’t need any actual Rasam Powder to make this tomato rasam.
Below I share two of my favorite variations of tomato rasam. While the methods to make them are similar, the second recipe has a much greater kick of spiciness.
- Tomato Rasam (Thakkali Rasam) – Made without tamarind and rasam powder (My mom’s special recipe). This version has a more sour, tangy tomato flavor. This recipe also has a video.
- Tomato Charu – Andhra Style Spicy Tomato Rasam recipe. A spicier, smokier dish.
Both recipes are easy to make and are delicious to enjoy as a soup or with rice. Simply choose how spicy you like your tomato rasam!
Ingredients You Need
For the first tomato rasam recipe aka thakkali rasam, we use cumin seeds and black pepper as the main spices. You can increase or decrease the proportion of pepper to adjust with your taste and desired level of spice.
Other ingredients that are needed are tender coriander stems (cilantro, with or without leaves), ginger and garlic. Again, feel free to use more or less ginger and garlic depending on how fragrant you want your dish.
Plus you also need, of course, juicy red tomatoes and plenty of Indian spices and herbs.
How to make Tomato Rasam
Make Ground Herbs And Spice Mixture
1. To a blender or food processor add ⅓ cup (about a handful) of roughly chopped coriander stems, with or without leaves. Add 7 to 8 medium sized garlic cloves, peeled, and 1 inch of peeled ginger, roughly chopped.
2. Add 2 teaspoons of cumin seeds and ¼ teaspoon of whole black peppercorns. Feel free to use less or more pepper to taste.
3. Grind to a coarse paste, but do not puree. Transfer the paste to a bowl or plate and set aside.
Making Tomato Puree
4. To the same blender jar add 3 large ripe and red tomatoes, rinsed and chopped. You will need 275 grams tomatoes, or roughly 1.5 to 1.75 cups of chopped tomatoes.
5. Blend the tomatoes to a smooth puree. For a beautiful bright red rasam, you can first blanch the tomatoes and then puree them.
To blanch tomatoes, boil them in a pot of water for one to two minutes before quickly plunging in a bath of ice water. This stops the cooking process and keeps the tomatoes super red and juicy.
Fry The Spices, Herbs
6. In a heavy pan or pot, heat 2 tablespoons oil on low heat. Once the oil is hot add ½ teaspoon of mustard seeds.
You can use gingelly oil (made from raw sesame seeds) or sunflower, peanut or any neutral oil.
7. Fry the mustard seeds until they begin to crackle.
8. Next add ½ teaspoon of urad dal (lentils). I have used whole urad dal, but you can even use split and husked lentils.
While the dal adds great texture and taste, feel free to leave them out if you don’t like them or don’t have any on hand.
9. Continue to stir often as you fry the urad dal to a golden brown.
10. Add 1 to 2 dry red chilies (halved and seeds removed), and 1 pinch asafoetida (hing). Turn the heat off if the pot gets too hot and nearly smokes.
11. Stir and fry the chilies for few seconds, until they start to lose their red color and become reddish brown.
12. Add the coarsely ground coriander, ginger, cumin, black pepper and garlic paste to the pan. Again, if the pan is so hot that anything begins to burn, promptly turn the heat off and/or remove the pan from the stove.
13. Now add 10 to 12 curry leaves, whole or chopped.
14. Sauté for a minute on low, being careful to not burn the spices.
15. Add ¼ teaspoon of turmeric powder.
16. Stir to thoroughly blend the turmeric powder in with the spice mixture.
Making Tomato Rasam
17. Carefully add the tomato puree.
18. Mix well. The tomato rasam will almost immediately smell amazing.
19. Continue to stir and simmer for a minute to heat the mixture through.
20. Season with salt to taste.
21. Next add 1.5 cups of water, and stir. If you want a thinner soup you can add a splash more water. But I don’t recommend adding too much more, or you risk diluting the delicious flavors of the thakkali rasam.
22. Increase the temperature to medium-low heat and bring the soup to a gently boil. Stir again, and reduce the heat back down to low.
23. Simmer for about 10 minutes, stirring occasionally.
24. Turn off the heat and add 2 tablespoons of chopped coriander (cilantro) leaves. Taste, and add more salt if needed.
Serving Tomato Rasam
Serve tomato rasam or thakkali rasam hot, either like a curry over steamed white rice or enjoy as a bowl of hearty soup. Both ways are great with a side of pappadums or simple toasted bread.
Storage
Refrigerate any leftovers for a day. Reheat the tomato rasam in a small pot or pan until warm or hot. If you plan to make ahead the thakkali rasam then do not add coriander leaves. After you reheat rasam, add the coriander leaves.
Helpful Tips
- Tomatoes: Tomato rasam is best made with fresh, red, ripe tomatoes. Any variety of red tomatoes work, provided they are ripe.
- Spices: For a spicy and robust thakkali rasam, increase the amount of whole black peppercorns by adding a total of ½ teaspoon.
- Oil: Traditionally in the Tamil Nadu cuisine, rasam is made with gingelly oil. This gingelly oil is nothing but wood pressed oil extracted from raw sesame seeds. In a pinch you can opt to use sunflower oil, peanut oil or any neutral oil.
- Urad dal: Omit urad dal if you do not have these lentils.
- Asafoetida: For a gluten-free tomato rasam do not add asafoetida or use gluten-free asafoetida.
About Tomato Charu
Tomato charu is the Andhra version of rasam made with tomatoes, spices, herbs. This is a soupy spicy vegan recipe that is quick to make.
Rasam is called as “charu” in Andhra Pradesh and “saaru” in Karnataka. There are many ways of making tomato charu.
Whenever I make tomato charu, I usually puree the tomatoes. Of course, you can crush or chop the tomatoes too, but we like them pureed. The tomato puree can also be strained if you want.
You can blanch or skip blanching tomatoes, before pureeing them. I usually make quick lunch and dinners, so I do not blanch the tomatoes.
A bit of tamarind also goes in this charu recipe. Though skipping it also is fine, if you do not have it.
Tamarind simply make the tomato charu a bit more tart, than what it would be with only the tomatoes included in the recipe.
Step-by-Step Tomato Charu (Andhra Style)
Make Tamarind Pulp
1. Soak 1 teaspoon tamarind in ¼ cup hot water for 15 to 20 minutes.
2. Then squeeze the tamarind and extract the pulp.
Make Tomato Puree
3. When the tamarind is soaking, chop 250 grams tomato (4 to 5 medium tomatoes).
4. Add them along with their juices from the chopping board to a blender jar.
5. Blend to a smooth puree.
Cook Tomato Puree
6. Take the tomato puree in a pan or pot.
7. Now add ¼ teaspoon turmeric powder and ½ teaspoon red chili powder.
8. Then add 2 cups water and mix very well.
9. Keep the pan on the stovetop. Cover with a lid. Then on a low to medium flame simmer the tomato mixture for 3 to 4 minutes.
10. Then remove the lid and continue to simmer for 1 to 2 minutes or until the raw flavors of the tomatoes are not there.
Add Tamarind Pulp
11. Next strain the tamarind pulp over the tomato broth carefully, taking care that the steam does not touch your hands.
Or you can switch off the heat and add the tamarind pulp. You can also add the tamarind pulp directly without using a strainer.
12. Mix well.
Add Seasonings and Rasam Powder
13. Next add salt as per taste. Then simmer for 4 to 5 minutes.
14. Then add 2 teaspoons Rasam Powder. Cook for a further 3 to 4 minutes. A bit of jaggery (about ½ to 1 teaspoon) can also be added to balance the sourness of tomatoes.
If you do not have rasam powder, you can skip it, but the taste of the tomato charu will be different.
15. Cover with a lid and set aside.
Tempering
16. Heat 1 tablespoon oil in a small pan or tadka pan. Add ½ teaspoon mustard seeds and let them crackle.
17. Then add ½ teaspoon cumin seeds and let them splutter.
18. Next add 2 dry red chilies and 10 to 12 curry leaves along with a generous pinch of asafoetida (hing).
Making Tomato Charu
19. Fry until the red chilies change color and curry leaves become crisp and add this entire tempering mixture to the tomato charu.
Cover the pan for 4 to 5 minutes so that the tempering flavors infuse into the tomato charu.
20. Then remove the lid and add 2 to 3 tablespoon chopped coriander leaves.
22. Serve the andhra style tomato charu with steamed rice or you can drink it as a soup.
Store leftovers in the refrigerator for a day. Reheat until warm or lightly hot in a sauce pan.

Hello Dassana,
I discovered your blog yesterday and I already want to try several (if it’s not all) recipes.
I (french) cooked the tomato rasam last night for my husband (indian) and he loved it! It’s easy to make and very good with idli 😉
Thank you so much for sharing your recipes!!
thank you cecilia for sharing this lovely comment and reviewing the tomato rasam recipe. wish you all the best and happy cooking. you can try any recipe which you want to make.
Dear Dassana,
This is my first comment on your blog, although I have been cooking with its help for more than three years now. I am commenting on this post because this was the most recent recipe I tried.
Your blog has been my teacher of Indian vegetarian cooking. I have looked up a lot of dishes I knew of, and wanted to learn how to cook, and also regional dishes that were entirely new to me. Every time, your recipe has been reliable, very detailed and easy to follow, and the dishes always turn out delicious (although as I live abroad now, and don’t have a pressure cooker or access to certain spices like dagarphool, so I do have to improvise).
So, for that, I have been to write to you, first to thank you, and second, to ask you to please create a cookbook. I would be first to buy 10 copies, one for me and nine to gift friends and family who are a loss for what to cook for everyday meals and for special occasions.
In case I have missed out on the news that you do already have a cookbook, please let me know!
thank you very much mia for this lovely comment. felt good and heart warming to read your comment. i am so glad that the detailed step by step recipes are helping you. i do know that certain spices or ingredients are not easily available outside india.
currently i have been postponing the idea of a cook books. things are just not falling into place. i hope i am able to have a cookbook in future… hopefully… if i write a cookbook then for sure i will update it on the blog as well as on the social media channels like fb, twitter, instagram etc.
I am surprised that publishers are not knocking your door down 🙂 I mean, the text is written, the photos have been shot, and the recipes have been tested and rated by soooo many of us users.
anyway, I hope stars will align soon, and you find the right time and conditions to put all of your hard work in to a cookbook – or series of them. I am in for the vegetables!
in the meantime, I will be coming back every week to your blog for guidance.
mia, i have been approached by some publishers. unfortunately things did not fall into place. thanks a lot for your kind wishes. i hope too ????
sure you can visit the blog when you want to try any recipes. any query please don’t hesitate. you can always ask.
Can i have it with Bihari LITTI?
prabha, not sure how the combination will taste. but i think one can always give a try ????
