Trivia and Origins

Onion bhajis have roots in Indian street food, where vendors would fry spiced onion batter over open flames, creating irresistible snacks that traveled well.
The dish likely traveled from Indian subcontinent to Britain during colonial times, where it evolved into the crispy, deep-fried snack loved today.
In the UK, onion bhajis became a staple in fish and chip shops, blending British pub snacking with Indian flavors—an accidental fusion born of convenience and craving.

Ingredient breakdown

Onions: I prefer yellow onions for their balanced sweetness and sharpness, which become oozy and fragrant when fried—skip the milder varieties if you want that punch of flavor.
Chickpea flour: It gives the bhajis a crispy, smoky crunch—try rice flour if you’re avoiding chickpeas, but expect a slightly lighter bite.
Spices: Cumin, coriander, turmeric—these warm the batter with earthy aroma and color. Adjust to your taste, but don’t skip the turmeric; it adds a golden hue and depth.
Water: I keep the batter just loose enough to coat the onions—if it’s too thick, they’ll be greasy; too thin, they won’t hold together—test by dipping a spoon.
Oil: Use a neutral oil with a high smoke point like vegetable or sunflower. When shimmering and crackling, it’s ready—if it smokes excessively, turn down the heat.
Salt: I add it to balance the spices, but taste the batter before frying—over-salted batter can overshadow the onion’s natural sweetness.
Optional herbs: Fresh coriander adds a burst of green and freshness—skip if you prefer a more straightforward, onion-forward bite.

Spice Level: Add chili powder or fresh chopped green chilies for more heat, or skip for a milder snack.
Onion Type: Use red onions for a sweeter, milder flavor, or shallots for a more delicate, tender bite.
Oil Choice: Use sesame or coconut oil for distinct aroma and flavor—watch their smoke points, adjust heat accordingly.
Herbs & Extras: Fresh cilantro or mint can brighten up the flavor—skip if you want a straightforward onion punch.

Step-by-step guide to onion bhajis

Equip your station with a large mixing bowl, a sharp knife, a slotted spoon, and a heavy-bottomed pan or deep fryer. The bowl is for mixing, the knife for slicing, the spoon for scooping, and the pan for frying.
Peel and thinly slice 2 large yellow onions. Aim for about 2mm thickness—think paper-thin, so they cook evenly and get crispy.
In the bowl, combine 1 cup chickpea flour, 1 teaspoon cumin, 1 teaspoon coriander, 1/2 teaspoon turmeric, and a pinch of chili powder if you like heat. Mix well.
Add the sliced onions to the bowl. Toss to coat thoroughly with the spice and flour mixture. The onions should feel slightly sticky and coated, not dry.
Pour in about 1/4 cup cold water gradually, mixing as you go. The batter should be loose but hold together when you scoop. If it’s too runny, sprinkle in a little more chickpea flour; if too thick, add a splash more water.
Heat your oil in the pan over medium-high heat (~180°C / 350°F). To check if ready, drop in a small piece of batter—if it sizzles and rises quickly, you’re good to go.
Once hot, use a spoon or your hands to scoop small portions of the batter, roughly 2 tablespoons each. Gently slide them into the oil—don’t overcrowd the pan.
Fry for about 3-4 minutes per batch, turning occasionally. Look for deep golden brown and crispy edges. The smell should be smoky, spicy, and inviting.
Use a slotted spoon to lift out the bhajis. Drain on paper towels to remove excess oil. If they’re not crispy enough, increase the heat slightly and fry a little longer.
Let the fried bhajis rest for 1-2 minutes before serving. They should be crackling, tender inside, with a golden exterior.

Let the bhajis sit briefly on paper towels to drain excess oil. Serve hot with chutney or yogurt. They’re best enjoyed immediately while crackling and warm, but can be kept warm in a low oven for 10-15 minutes.

How to Know It’s Done

Ingredients Equipment Method

Ingredients

2 large yellow onions thinly sliced, about 2mm
1 cup chickpea flour also known as gram flour
1 tsp cumin ground
1 tsp coriander ground
1/2 tsp turmeric adds color and warmth
1/4 tsp chili powder optional, for heat
1/4 cup cold water adjust as needed for batter consistency
to taste salt add after mixing
2-3 cups neutral oil vegetable or sunflower, for frying
optional fresh coriander chopped, for extra flavor

Equipment

Large mixing bowl
Sharp knife
Slotted spoon
Heavy-bottomed pan or deep fryer
Kitchen thermometer
Paper towels

Method

Peel the onions and thinly slice them to about 2mm thickness, aiming for almost paper-thin slices that will crisp nicely when fried. Set aside in a large mixing bowl.
In the same bowl, add the chickpea flour, ground cumin, coriander, turmeric, and chili powder if using. Mix these spices into the flour to create an aromatic, evenly combined dry mixture.
Pour the cold water gradually into the spice and flour mixture, stirring gently to coat the onions evenly. The batter should be loose but hold together when scooped—add more water if needed, or a little extra chickpea flour if too runny.
Season with salt to taste and add chopped fresh coriander if desired. Mix everything thoroughly until the onions are well coated with the batter, feeling slightly sticky but not wet.
Heat the oil in a heavy-bottomed pan or deep fryer to about 180°C (350°F). To test if the oil is ready, drop in a small spoonful of batter—if it sizzles and rises to the surface quickly, the oil is hot enough.
Using a spoon or your hands, scoop about 2 tablespoons of batter and gently slide it into the hot oil. Be careful not to overcrowd the pan, as this can lower the temperature and lead to greasy bhajis.
Fry the bhajis for 3-4 minutes, turning occasionally, until they are deep golden brown and crispy on the edges. You should hear a gentle crackling sound and smell a fragrant, spicy aroma.
Use a slotted spoon to lift out the crispy bhajis and drain on paper towels to remove excess oil. Continue frying the remaining batter in batches, maintaining the oil temperature.
Let the fried bhajis rest for a minute or two, then serve hot with chutney or yogurt. Their crackling exterior and tender, aromatic onion interior make them irresistible.

Pro tips for perfect onion bhajis

Bolded mini-head: Use a gentle hand when mixing the batter—overworking can make bhajis dense instead of crispy.
Bolded mini-head: Maintain oil temperature around 180°C (350°F) for even crispiness; too hot and they burn, too cool and they get greasy.
Bolded mini-head: Add water gradually to the batter—if it’s too runny, add more chickpea flour; if too thick, splash in a little more water.
Bolded mini-head: For maximum crunch, fry in small batches—overcrowding drops the oil temperature and softens the bhajis.
Bolded mini-head: Use a slotted spoon to gently lower batter scoops into oil—avoid splashing to prevent burns and uneven frying.
Bolded mini-head: Let fried bhajis rest briefly on paper towels—this helps drain excess oil and keeps them crisp.
Bolded mini-head: For extra flavor, sprinkle a pinch of flaky sea salt immediately after frying—this enhances the savory punch.

Common mistakes and how to fix them

TOO MUCH ONION: Use finely sliced onions to avoid soggy bhajis; too thick slices lead to uneven cooking.
DUMPED BATTER: Ensure batter is loose but not runny; too thick or thin ruins texture and frying process.
OVER-TORCHED OIL: Keep oil temperature steady around 180°C (350°F); too hot burns exterior, raw inside.
UNDERSALTED: Taste the batter before frying; too little salt makes bhajis bland, too much overwhelms onion flavor.

Quick kitchen fixes

If oil smokes excessively, splash in a bit of water to calm the heat.
When batter feels too thick, add a splash of cold water to loosen it.
Splash cold water on hot oil if the crackling noise stops suddenly.
DUMPED batter? Mix in a little more chickpea flour for better coating.
When bhajis are soggy, immediately increase oil heat and fry briefly again to crisp.

Prep, store, and reheat tips

Prep the sliced onions and batter mixture a few hours in advance; keep refrigerated to preserve freshness and prevent oxidation, which can turn onions brown and alter flavor.
Store leftover cooked bhajis in an airtight container in the fridge for up to 2 days. Reheat in a hot oven (around 180°C / 350°F) until crispy and fragrant, about 5-7 minutes, watching for that crackling sound to return.
Uncooked batter can be frozen for up to a month—thaw overnight in the fridge before frying. Expect a slightly denser texture, but still good for a quick snack.
Reheating fried bhajis in the microwave isn’t ideal—they tend to soften quickly. For best results, crisp them up again in the oven or a toaster oven, checking often for that sizzling, golden crunch.
