Frying the perfect crispy crunchy golden brown onions is almost equivalent to the perfect gol roti (flatbread). In brown people world, its a sign of a “perfect wife/bahu or watever” I could give a rat’s behind as to what it makes me. All I know is I want my food to taste frikkin awesome ok? Whether I am making Biryani or Chicken curry or Pulao, I want my taste buds happy!
Just like garlic ginger paste, crispy fried onions is one of the basis of all South Asian cooking and if you nail it, you pretty much have MASTERED one of the CORE ingredients in almost ALL Indian/Pakistani curries.
So getting these beautiful crispy onions is honestly just a few tips and tricks away. But behold...since it is something we struggle with, the internet has come up with WEIRD and absolutely useless tips and tricks as well. I’ll mention some really popular myths below as well so that you know what to stay away from as well.

Here’s are a few key things to know about frying onions.
Choosing the right onions
There are 6 kinds of onions:
- Red onion
- white onions,
- yellow onions,
- sweet onions,
- shallots and
- Scallions / Green onions
The internet will tell you that the ideal onions for frying are the sweet onions. And it won’t be completely wrong. They do have a uniform color through out and the perfect amount of natural sugars that fry up to give you a uniform golden brown color. But they don’t have thin layers, which when sliced, will not give you nice thin slivers. Thin layers are important for that crispy frying. You can use any, white onion, red onion, or sweet onion, as long as they have thin layers. And you will great results! Where I live, red onions are the ones with the thinnest layers so I pick those.
Keep dipping your peeled onions in a pot or bowl of cold water. Helps with the tears (more on that below)
Cutting the onions
The onions are peeled, halved vertically and their roots are removed. And then cut into long thin slices. This is also known as the “biryani cut” onions. Obviously this is a tedious task to do by hand and when done in bulk can feel like a truckload of work. You can use the slicer option in your food processor to slice your onions the easy way. You can also use a manual mandoline slicer to do the deed as well. Of course the food processor is quicker, but a mandoline is also twice as fast as manual slicing.
How to avoid crying while cutting the onions
So, so far with all the methods I’ve tried, all I can say is, crying a li’l is inevitable (yeah you hate me I know). Maybe do it in a well ventilated area or near a candle so the gases don’t effect you as much? But here’s a good read on how to avoid crying if you wanna check it out.
Selecting the pot
So it all comes down to size and area. Imagine frying french fries. Your fries are going to get clumpy and soggy if you toss them in a small space. The same rule applies while frying onions. So opt for a wider shallow utensil with a thick base. Give your sliced onions room to crisp up individually.
Thick base, wide and can withstand high temperatures.
Selecting the oil
When frying onions, or any other thing for that matter, you want to make sure that your oil has a neutral flavor and a high smoke point. The temperatures can go up to 190 C while frying onions and you want to use an oil that can stay stable for that long. Basic vegetable oil like sunflower oil and canola oil can easily stay stable at those temperatures. If you are on a keto diet or are trying to live a healthier lifestyle, coconut oil is also a good option for frying as it can stay stable up to 180 C. As an alternative, you can also use ghee.
Important: Always use fresh oil when you want the perfectly nice brown onions. Oil that has been used once to fry before is going to take double or triple time to brown onions and you will end up with onions that have soaked up a LOT of oil!
How much quantity of oil to use
When frying onions for one time use, you can get away with using very little oil and stirring constantly to get a good color. But for a large batch, you will definitely need to use oil enough for deep frying. So adding a truck load of oil in the onions seems like OMG this is soooooo frikking unhealthy. But trust me when I say this. If you fry your onions right, your onions will NOTTT absorb a lot of oil. You can even measure the amount of oil you put in the pan before frying and how much oil is left AFTER frying.
While growing up I kept hearing this very popular TOTKA (aka tip) that adding onions in cold oil makes it crispier. This, of ALL THE hacks out there, is the only one that LEGIT works. All it does is absorb more oil. Always add onions to oil that has already started to heat up. Doesn’t need to be boiling hot, just warmed up. And keep frying your onions at high heat.
TIP: Add onions and oil together in a pot first and then putting them on a flame to fry for crispy onions
You can easily eyeball the amount of oil you want to add. Toss in your onions in the pot you are going to fry them in. And THEN add oil to it till it comes up to the level of the onions roughly.
TIP: Don’t I repeat DON’t Add stuff to your oil
Lots of internet groups and articles suggest to add baking soda or salt or sugar to your oil in hopes of achieving a uniform brown color. PLEASE do NOT commit this heinous crime! Not only will these ingredients make your onions absorb MORE oil, but it will also alter the natural sweet taste of the fried onions, and eventually might also effect the dish you are preparing your fried onions for.
TIP: Use a slotted stainless steel spoon or skimmer for stirring through the onions. Try not to stir too much, just occasionally a stir here and there, making sure all the onions are getting evenly fried.
Reaching the right color
When you keep your pot with onions and oils onto the stove, turn on the flame directly at a high. You will begin to notice the changes that the onions will go through during its frying journey.
(TIMINGS FOR BULK FRYING)
5 to 10 min mark – The oil will get hot and the onions will start releasing water of their own. (Stir from sides once in 5 mins)
15 min mark– The onions will start to dehydrate at the water evaporates and will start to shrink in size. (Stir once or twice to check even browning)
20 min mark – The onions will turn very light gold and have now officially started to crisp up. (stir once or twice and now stay close)
25 min mark – Onions have started to crisp up. Some thinner ones are golden already. Reduce the flame to medium and stir constantly. Start removing onions that have turned golden.
Between 25 to 30 min – This is a critical time. When you see your onions are just ABOUT to reach the perfect color, reduce the flame to low and start removing them with the skimmer. The oil is hot and the onions will turn a shade darker after getting removed as well. If you wait till you reach the right color and THEN start removing onions, the last batch you remove will be burnt.
Letting the onions cool down.
You should have a large tray or plate lined with paper towel ready on the side when you start frying the onions. Remove all your fried onions from the oil and place them directly on top of these paper towels. Make sure they are spread out evenly. Allow the onions to cool down. Its important for the onions to cool down in as much space as possible, in order to crisp up properly. You can press the onions together once they cool down, and you’ll hear a gentle crisp. Which will say, all of your effort, was well WORTH IT!
1 medium onion is equal to 1/2 cup of fried onions and 1/4 cup of crushed fried onions.
Storing the onions
The best part about all of this hard work is that you can savor it! You can batch fry lots of onions in one go and freeze them! They are totally freeezer friendly and can last indefinitely! (I’ve always used them within 4 months, but I don’t see a reason why they won’t last longer than that) Once the onions cool down, bag them up in a ziplock bag and keep it in the freezer. If you want to use them in the coming days, they can even stay outside in a jar for a week.
What to do with the left over oil?
I usually fry my onions when I have a fresh bottle of cooking oil, and a big batch of onions, i.e. when I have freshly done my groceries. Let the remaining oil cool down and use a funnel to transfer it back to the bottle you had used it from. This oil has a nice sweet oniony flavor to it and can be used basically for everything savory. Of course not for sweets, and definitely not for more deep frying.
Bonus: If you are using pre-fried onions in your curry etc, you can make those with about 1 tbsp of oil, because all the oil that goes in a gravy is usually to fry the onions. And if that’s already done, you don’t need anymore!
