Save to Pins My neighbor brought over a batch of onion bhaji from the local Indian market last summer, and I bit into one while standing in her kitchen, the oil still glistening on my fingers. The crunch was immediate, the spices warm and layered, but what struck me most was how she casually mentioned making them at home in her air fryer, cutting the oil by half while keeping that golden, shattering texture intact. I spent the next week pestering her for the technique, and when she finally walked me through it, I realized this was the answer to every craving I'd been ignoring because of the guilt that comes with deep frying. Now these bhaji are in regular rotation on my countertop, ready in thirty minutes, and honestly, no one can tell the difference.
The moment I knew this recipe was a keeper was when my partner's parents came over unannounced on a Tuesday evening, and instead of panicking, I had a fresh batch of these bhaji ready within the time it took them to settle in the living room. Watching his mother's face light up as she bit into one, then ask how I'd made them so crispy without the traditional oil soak, felt like a small victory in the kitchen that went beyond just feeding people.
Ingredients
- Large onions, thinly sliced: The foundation of these fritters; slicing them thin ensures they cook through and create those delicate, crispy layers that make bhaji so addictive.
- Green chilies, finely chopped: These bring a sharp, fresh heat that builds as you eat; leave them out if you prefer milder fritters, or add an extra one if you like that slow burn.
- Fresh cilantro, chopped: This isn't just garnish—it adds a grassy brightness that cuts through the richness and keeps each bite interesting.
- Gram flour (besan): This chickpea flour is the binding hero here, creating a batter that clings to the onions without needing eggs; it's naturally earthy and gluten-free.
- Rice flour: A small amount adds extra crispness and lightness, preventing the bhaji from becoming dense or heavy.
- Ground cumin and coriander: These warm spices are what make bhaji taste like bhaji; don't skip them or substitute, as they're essential to the flavor profile.
- Turmeric, chili powder, salt, and black pepper: Together, these build depth and warmth throughout the fritter, with turmeric adding a subtle earthiness and color.
- Baking powder: This gives the bhaji lift and airiness, especially important when air frying instead of deep frying.
- Lemon juice and water: The lemon brightens the spices and helps bind the mixture, while water is added slowly to reach the right consistency—thick enough to hold its shape.
- Spray oil: Use whatever neutral oil you prefer; a spray bottle gives you control and uses far less oil than traditional methods.
Instructions
- Prepare your aromatics:
- Place your thinly sliced onions, chopped green chilies, and fresh cilantro in a large mixing bowl and give them a little toss to combine. The onions will start releasing their moisture as you mix, which is exactly what you want.
- Build your dry blend:
- Add the gram flour, rice flour, and all your spices—cumin, coriander, turmeric, chili powder, baking powder, salt, and pepper—directly to the bowl with the onions. Toss everything together gently but thoroughly until every onion slice is coated in the flour mixture and the color is even throughout.
- Create the batter:
- Squeeze in the lemon juice and add two tablespoons of water, then mix everything with your hands, breaking up any clumps as you go. You're aiming for a thick, cohesive batter that holds together when squeezed but isn't wet or pasty; add more water only a teaspoon at a time if it feels too dry.
- Heat your air fryer:
- Set it to 180°C (350°F) and let it preheat for three minutes—this ensures even cooking from the moment your bhaji hit the basket. While it's heating, lightly spray the air fryer basket with oil so nothing sticks.
- Shape and arrange:
- Scoop heaped tablespoons of the mixture and gently shape them into loose patties or rough clumps with your hands; they don't need to be perfect, and that rustic look actually adds to their charm. Arrange them in a single layer in the basket without crowding, leaving a little space between each one so the air can circulate.
- The critical spray:
- Lightly spray the tops of each bhaji with oil before they go in—this is what creates that golden, crispy exterior. Don't skip this step or use too much; a light mist is all you need.
- Air fry until golden:
- Cook for twelve to fifteen minutes, turning them over halfway through and giving them another light spray of oil on the second side. You'll know they're done when they're deeply golden and crisp to the touch, not soft or pale.
- Serve while warm:
- Transfer them to a plate lined with paper towels to catch any excess oil, then serve immediately with mint chutney, tamarind sauce, or even a cool yogurt dip for contrast. The texture is best within the first few minutes while they're still hot and crispy.
Save to Pins There's something deeply satisfying about pulling open the air fryer drawer and seeing those golden, puffed-up bhaji tumbling around, still crackling softly. It's one of those small kitchen moments that feels almost ceremonial, the promise of something crispy and fragrant that's about to make someone happy.
Customizing Your Bhaji
Once you understand the base recipe, these fritters become a playground for whatever vegetables or flavors you're drawn to that day. I've added finely chopped spinach for earthiness, shredded carrot for sweetness, even a handful of paneer for richness, and each version feels like a conversation with the ingredients rather than a strict formula. The key is keeping the ratio of vegetables to binding flour relatively consistent, and remembering that anything you add should be chopped small enough that it cooks through in the fifteen minutes the bhaji spend in the air fryer.
Storing and Reheating
These bhaji are best eaten fresh, but if you have leftovers, they'll keep in an airtight container in the fridge for three days, and you can reheat them in the air fryer at 160°C for about five minutes to restore their crispness. I've also found that the raw batter can be frozen in portions, so on a lazy evening when I'm hungry for something crispy and spiced, I can pull out a tablespoon of mixture and have fresh bhaji ready in under twenty minutes.
Pairing and Serving Ideas
These bhaji shine brightest alongside a cool, creamy dip that offers contrast and balance—mint chutney with its bright herbaceousness is traditional and my go-to, but I've also served them with a simple yogurt mixed with cumin and salt, or even a tamarind sauce for tanginess. They work as an appetizer before a larger Indian meal, as a snack during the day with tea, or scattered across a board of other small bites for entertaining.
- Make a double batch and freeze the raw batter in portions so you always have crispy bhaji within reach.
- Serve them immediately while they're still hot and crunchy; they lose their texture appeal once they cool completely.
- Pair with something cold and creamy to balance the warm spices and give your palate a refreshing break between bites.
Save to Pins These air fryer onion bhaji have quietly become the thing people ask me to bring to gatherings, not because they're fancy or complicated, but because they taste like care and taste like comfort all at once. There's real joy in knowing you can deliver something this good, this crispy, this spiced, in the time it takes to chat with a friend.
