I am on a mission to help you simplify Indian cooking! Grab your onions and tomatoes and get ready to make some Indian onion masala!
What is Indian Onion Masala?
Indian onion masala is a flavorful sauce made up of onion, tomato, ginger, garlic, and spices. It’s the base of many Indian dishes, and by preparing it in advance, you can significantly reduce the cook time for many Indian recipes.
(If you can’t eat tomatoes, I have a nomato onion masala you can use instead!)
I have been watching my parents make onion masala, also known as onion tomato gravy, for as long as I can remember. In the past, making this masala was a painstaking process, but it doesn’t have to be anymore – especially if you have an Instant Pot. Having this onion tomato masala handy is an incredible time-saver and makes it possible to eat authentic, healthy, and delicious Indian meals every day.
Onions, tomatoes, and ginger/garlic are what I like to consider the “trifecta” of Indian cooking (…er quadfecta?). But who has time to brown onions and cook down tomatoes every single day? No one. That’s why many Indian people spend one day a week or a month preparing Indian onion masala. It can take several hours to fry onions and cook down tomatoes, but I have a faster way: use the Instant Pot. You prepare a big batch, freeze it, then take it out whenever you need to make a quick meal.
I know everyone is all about “meal prep” these days. Well, this is how a lot of Indians meal prep. Once you’ve got this masala ready, you can literally prepare “dump and go” Indian recipes, and they’ll end up having a lot of flavor.
As magical as an Instant Pot is, it’ll still take time to make this masala – just not as much. Plus, you won’t have to babysit a pot on the stove for as long. It’s really up to you as to how brown you’d like to have your onions. I sometimes skip fully browning the onions, and the masala still turns out just fine. The browner the onions, the sweeter the masala, so if you can, be patient.
This is how brown your onions should look if you sauté them for 15-20 minutes first:
This masala lasts for months. When I first gave birth to Tony, my mom packed my freezer to the brim with this masala, and literally, one year later, I found some of it hiding in the back of the freezer… not gonna lie, I used it, and it was still perfect. I’d probably suggest using it up within six months though (it normally doesn’t last us that long).
So forget peeling, chopping, and cooking these basic ingredients every single day. That is exhausting, and what makes Indian cooking seem unapproachable. Instead, make this onion masala and see how easy it really is to cook fresh Indian food every day.
Fresh Tomatoes or Canned Tomatoes?
You can use either fresh tomatoes or canned tomatoes to make this onion masala, and I’ll explain how to do that in the directions below.
When it comes to fresh tomatoes, I suggest using Roma tomatoes because they have less water content and so the masala will be thicker. If you use different tomatoes, then you may need to boil off some of the water at the end.
If ripe tomatoes are not in season where you live or you prefer convenience, then go for canned (or jarred) diced tomatoes. Canned tomatoes are picked at the peak of ripeness, and ripe tomatoes are what will make your masala tasty. Sometimes canned tomato masala turns out to taste a bit better for this reason.
(Just an FYI: the photos in this blog post are of tomato masala made using fresh tomatoes. Canned tomatoes will give the masala a darker color).

How to Store Onion Masala:
Here is a detailed post that you can read to learn how I freeze onion masala: How to Store and Use Indian Onion Masala
The short version: I store it in these silicone molds – each mold holds ÂĽ cup of onion masala.
Recipes to Make Using Onion Masala:
And that’s just a short list! For even more ideas, visit my Onion Masala Recipes page.
Suggested
I recommend using this silicone mold to store the onion masala. Each well holds ÂĽ cup of onion masala. So if a recipe calls for 1 cup of masala, you’ll know to use 4 cubes of masala.
Ingredients
- ½ cup oil neutral oil like avocado oil is great
- 2 pounds yellow onions approx. 6, diced
- 1 head of garlic approx. 12 garlic cloves, chopped
- 2- inch ginger chopped
- 2 pounds roma tomatoes approx. 9 tomatoes, chopped OR 2 (14.5 ounce) cans of diced tomatoes
- ÂĽ cup water
Spices (adjust to taste):
- 3 tablespoons ground coriander
- 1 tablespoon paprika
- ½ teaspoon ground cumin
- ½ teaspoon turmeric
- ÂĽ teaspoon cayenne
Instructions
- Press the sauté button on the Instant Pot, adjust the heat to the highest setting, then add the oil to the pot. Wait for the oil to get hot, then add the onions.
- Cook the onions for 15-20 minutes, stirring occasionally, until browned (keep the stirring to a minimum in the beginning to brown the onions faster. As the onions brown, stir more frequently).
- Add the garlic and ginger and stir-fry for 1-2 minutes.
- Add the tomatoes and cook for another 3-5 minutes or until the tomatoes cook down a bit. Stir the bottom of the pot to scrape off any brown bits. Add the water and mix well.
- Add the spices, give everything a good stir, then secure the lid, close the pressure valve and cook for 5 minutes at high pressure.
- Naturally release pressure.
- Blend the masala using a blender or an immersion blender (it can be smooth or slightly chunky – up to you!). The sauce will continue to thicken a bit as it cools.
- Once the masala is cool, I store it using this silicone mold which holds ¼ cup of onion masala per mold. Then go check out all of my onion masala recipes!

Notes
- Getting a burn error? Make sure you are using enough oil so that the onions don’t stick to the bottom of the pot! If there is anything stuck to the bottom, you can add ÂĽ cup water to help deglaze the pot. Make sure to remove any burnt bits before securing the lid! If there’s something stuck to the bottom, then you may get the burn error, but the chances are that if it comes to pressure, it’ll be fine once you open the pot. Some appliances/models may be more sensitive.
- If it’s not tomato season, use canned diced tomatoes (the whole contents of the can) for the best flavor.
- If using fresh tomatoes, I suggest using Roma tomatoes because they have less water content than other tomatoes. This results in a thicker masala. If using different fresh tomatoes, you will likely need to boil off the water at the end.
- Make sure to adjust the temperature to sauté at the highest setting when sautéing the onions. It is up to you as to how brown you would like the onions. I have skipped fully browning them before, and the masala still turns out well. The more caramelized the onions, the sweeter the masala will be.
- You can also make this masala without the ginger, garlic, and spices if you prefer. Just be sure to keep that in mind when preparing meals.
- Learn how to store this masala by reading this blog post. You will want to make sure the onion masala is cold before putting it in the freezer. I store it in the fridge first, and then once it’s cold, I put it in the freezer. This helps to reduce freezer burn.

I cannot rate this recipe yet, since I have not made it. First, I am curious:
How much giner paste can I use instead of whole ginger?
kristin says
Wow, a total gamechanger!!! I feel like I can finally cook several recipes at once in not as much time. This is such a huge help for me and my family!!!
Ashley - My Heart Beets says
Kristin, so glad to hear that! Thanks for letting me know how much you like this! 🙂
Annike says
How much time do you naturally pressure release for?
Most IP recipes will indicate either 1) manually pressure release or 2) naturally pressure release after X minutes.
Otherwise I don’t know when to open it…
Thanks!
Noha says
Hi Ashley. Just made a batch and looking forward to using them. Complete eye-opener idea to make these beforehand.
Wanted to ask you the reason for not including salt in the recipe? Does including salt affect the frozen or after-freezing cooking result somehow?
Thanks again!
Linda says
Hij Noha, I just noticed this too, and wonderd about it. And just thought to myself; I’ll just add it, for I always add it at this step if I cook it ‘normally’
Linda says
Ah, way down here I found Ashleys answer

Hi Kavitha, I don’t add salt to the onion masala – I add it to the recipes directly. This way I know exactly how much salt is going into a dish. Hope that helps!
Sarika says
I make this 2-3 times per year and freeze in 1/4 cup blocks. This weekend I made a double batch. I’ve been doing this for years. Thanks a billion!
Ashley - My Heart Beets says
Sarika, I’m so glad to hear that! Thanks for letting me know how much you like and use this masala 🙂
Leah says
I love this masala so much! It’s literally been life changing for me . I can now whip up a Punjabi feast in short time and none of my Punjabi in-laws are any the wiser. Thank you so much Ashley!
Ashley - My Heart Beets says
Leah, I’m so glad to hear that 🙂 Thank you for letting me know how much you like the masala!
Virginia says
My instant pot (I have the 8quart) always gives me a burn message unless I add like four times the amount of water the recipe calls for. Can I just cook this on the stove? How long would you cook it for? Thanks I love this onion Masala and all your recipes I’ve tried with it, just it always ends up too watery and I’m trying to figure out a way to get around that.
Ben says
I just made a batch of this on the stove top in a stainless saute pan. It took longer for the onions to caramelize but it worked just as well.
