You can smell a bhaji before you can see one. About a minute after the first spoonful hits the oil, the kitchen announces it to the rest of the house, and suddenly you’ve got company. This recipe is for that. Proper crispy bhajis, the kind you order a second plate of, from four things: onions, water, oil and a packet of Roosma Onion Bhaji mix. Twenty five minutes, start to plate.
Ingredients
- 2 medium onions
- 1 full packet of Roosma Onion Bhaji mix
- 250ml water
- Oil for frying
Short list on purpose. A from-scratch bhaji wants gram flour, rice flour and a row of spice jars you’ll open twice a year. The mix carries all of that already, the coriander, the red chilli, the turmeric, the fenugreek, ground and balanced so you don’t have to weigh a thing. You bring the onions.
Method
- Slice the onions thin. Rough half moons are fine, don’t chase perfection. Thin matters more than neat.
- Tip them into a bowl, add the mix, then pour the water in bit by bit, mixing as you go. You want a thick batter that clings to the onion. If it pours, it’s too thin. It should drop off the spoon like it can’t quite be bothered.
- Rest it for 5-10 minutes. The flours drink up the water, the spices wake up, and the bhajis hold together better for it.
- Heat your oil to about 170°C. No thermometer, no problem. Drop in a scrap of batter: if it sizzles and floats, you’re ready. If it sinks and sulks, wait. If it browns before you’ve counted to five, too hot.
- Drop in spoonfuls, a few at a time. Give them room.
- Fry for 3-4 minutes, turning now and then, until they’re deep gold all over.
- Drain on kitchen paper. The first one is the cook’s, that’s the rule. The rest go out while they’re still crackling.
Four small things that decide the crunch
Let the mix pull the water out. There is already salt in the pouch, and the moment it meets the onions it starts drawing moisture out of them. That is what the ten minute rest is doing. Do not skip it, and do not stretch it to an hour either, or you will be frying a wet batter.
Use less water than feels right. Add it a splash at a time, until the batter just clings to the onion. It should coat, not pour. A loose batter is the most common reason bhajis come out soft.
Mix the batter while the oil heats. Gram flour batter is best fresh. Get the oil going, make the batter, then fry. Batter that sits for half an hour goes slack and fries heavy.
Pick a neutral oil. Sunflower, vegetable or rapeseed all take the heat and stay clean-tasting. Olive oil burns long before you reach 170°C.
Air fryer onion bhajis
Let’s not pretend. Hot oil makes the crispiest bhaji and the air fryer won’t change that. What it makes is a different bhaji, less shatter, more chew, closer to a fritter. And on a weeknight when you can’t be doing with a pan of oil, it’s genuinely worth having.
Hold back about 50ml of the water so the batter sits thicker. Shape it into flat little patties. Flat is the trick, round ones just steam in the middle. Give both sides a spray of oil and go 12-14 minutes at 180°C, flipping halfway. Eat them with something cool and sharp and you won’t feel hard done by.
Why did my bhajis go wrong?
Nine times out of ten it’s the oil or the knife.
Soggy and greasy: the oil was too cool, so the batter drank it instead of sealing. Bring it back up to heat between batches, and don’t overload the pan. Every cold bhaji you add pulls the temperature down.
Raw in the middle: the onion was cut too chunky, or the spoonfuls were too ambitious. Thin slices, golf ball portions.
Falling apart: the batter was too thin, or it never got its rest. If the first one breaks up, stir another spoonful of mix through the bowl and carry on.
Dark and bitter: too hot. Gram flour goes from golden to burnt quicker than you’d think. Turn it down a notch and give the next batch an extra minute at a gentler sizzle.
What makes takeaway bhajis different?
Mostly, nerve. A takeaway bhaji is nearly all onion, held together with just enough batter. Most home versions end up the other way round. So coat the onions, don’t drown them.
The other trick is the double fry, and once you know it you’ll use it every time you have people over. Fry the bhajis until they’re pale gold, lift them out, let them rest. Just before serving, back into hot oil for a minute or so. That second fry is where the takeaway crunch comes from, and the bhajis can sit for an hour in between without anyone ever knowing.
Serving and storage
Bhajis want something cold and sharp beside them. Mint raita if you have it, mango chutney if you don’t, plain yogurt with a squeeze of lemon at a push. Three each as a starter is about right, though nobody has ever complained about four. They’ll also stand in for rice next to a curry.
Leftovers keep for 3 days in the fridge, or a month in the freezer once fully cooled. Bring them back in a hot oven, 200°C for five or six minutes, until they crackle again. Not the microwave. The microwave turns a bhaji into a sad little sponge, and it deserves better.
