Making onion bhajis from scratch is a tactile, sensory dance that pulls you into the kitchen. The way the onion slices soften and release their juices as they hit the hot oil, filling the air with a sweet, caramelized aroma, is truly something else. It’s not just about the crispy outside; it’s about the process—the feel of the batter in your hands, the crackle of oil, and the way the spices bloom during frying.
There’s something almost meditative about preparing these little fritters. Each step, from chopping the onions to watching them transform in the oil, feels rooted in tradition and memory. It’s a recipe that asks for patience and attention, rewarding you with bites that are intensely flavorful and satisfyingly crisp, with a warm, fragrant punch of cumin and coriander.

Trivia and history of onion bhajis
- Onion bhajis have roots in Indian cuisine, but they became a popular street snack in Britain during the 20th century, especially among South Asian communities migrating there.
- The crispy exterior and tender onion inside make them a comfort food that bridges cultural tastes, often enjoyed with chutney or yogurt dips.
- Historically, these fritters were made as a way to use up surplus onions and spices, turning simple ingredients into a flavorful snack.
- In many Indian households, frying onion bhajis is a communal activity, often part of festive gatherings or street food markets, creating a sense of shared tradition.
Ingredient breakdown
- Yellow onions: I love how their sweet, pungent aroma intensifies as they soften—use a sharp knife to get even slices, and watch for that translucent look to signal readiness.
- Chickpea flour: It’s gritty and nutty; I find it gives the bhajis a lovely crispy crust. If you’re gluten-free, this is your best bet—skip wheat flour altogether.
- Spices (cumin, coriander): I toss in freshly ground spices for a vibrant, warm aroma. Using pre-ground spices works, but fresh spices really bloom during frying.
- Chili powder: Adds a smoky heat that makes my nose tingle. Adjust quantity based on your spice tolerance, but don’t skip it—gives a fiery kick.
- Oil (vegetable or sunflower): I prefer neutral oil for frying—watch it shimmer and faintly smell like toasted nuts before sizzling, signaling it’s hot enough. If it smokes, your temperature’s too high, turn it down.
- Salt: It’s the flavor anchor—taste the batter before frying and tweak if needed. Too much can overpower, so go easy at first.
- Water or ice-cold water: I add just enough to bind everything together—test by forming a small ball; it should hold without being runny or stiff.

Notes for ingredient swaps
- Onions: Yellow onions are sweet and soft when cooked; swap with red onions for a sharper bite, or shallots for a milder, more delicate flavor.
- Chickpea flour: Gritty and nutty—gluten-free and authentic; substitute with rice flour if you prefer a lighter, crisper texture, but expect less chewiness.
- Spices: Cumin and coriander—freshly ground offers a vibrant aroma; pre-ground works, but grind your own for a more intense, aromatic punch.
- Chili powder: Adds heat and smoky depth; smoked paprika can replace it for a milder, smoky flavor, or omit for a milder bite.
- Oil: Vegetable or sunflower—neutral and high-smoke point; try peanut oil for a richer, slightly nutty aroma or avocado oil for a milder taste.
- Salt: Essential for flavor—adjust to taste; sea salt or Himalayan pink salt can add subtle mineral notes, but keep quantities similar.
- Water: Cold water helps batter stick; sparkling water can add extra crispness, or skip if the batter feels too runny, adding a little more chickpea flour instead.
Equipment & Tools
- Mixing bowl: Combine ingredients and form batter.
- Slotted spoon: Fry and drain bhajis from oil.
- Sharp knife: Slice onions thinly and evenly.

Step-by-step guide to onion bhajis
- Equipment & Tools: Gather a mixing bowl (to combine ingredients), slotted spoon (for frying), sharp knife (for slicing onions), chopping board (prep surface), and paper towels (drain oil).
- Thinly slice 2 large yellow onions, about 3mm thick, aiming for even strips—this helps them cook uniformly.
- In the bowl, combine 1 cup chickpea flour, 1 tsp cumin, 1 tsp coriander, 1/2 tsp chili powder, and 1/2 tsp salt; whisk together.
- Add the sliced onions to the bowl. Sprinkle over the spice mixture, then pour in 2-3 tbsp cold water. Mix thoroughly with your hands or a spoon, until the batter is sticky but not runny.
- Heat 1 liter of vegetable oil in a deep pan over medium-high heat (around 180°C / 350°F). To test if ready, drop a small bit of batter; if it sizzles and rises quickly, you’re good.
- Using a slotted spoon, carefully scoop spoonfuls of batter—about 2 tbsp each—and gently slide into the hot oil. Don’t overcrowd the pan; fry in batches if needed.
- a. Fry the bhajis for 3-4 minutes per batch, turning occasionally with tongs, until they’re golden brown and crispy.
- b. Keep an eye on the oil temperature; if the bhajis brown too quickly, turn down the heat slightly. If they’re pale and limp, increase heat slightly.
- When golden and crispy, lift them out with the slotted spoon and drain on paper towels. Check for uniform crispness and a uniform golden hue.
- Rest & Finish: Serve hot on a platter, with a squeeze of lemon or a side of tangy chutney. Let them rest a minute to settle—this helps retain their crispness.
- Checkpoints & How to Know It’s Done: The bhajis should be golden, crispy on the outside, and tender inside. The oil should shimmer but not smoke. The batter should hold together without falling apart when fried.
Serve immediately while hot and crispy. Place on a warm platter, garnish with fresh herbs if desired, and enjoy with chutney or yogurt dips. Let them rest for a minute to maintain crunch before serving.
How to Know It’s Done
- Color: Deep golden brown, crispy exterior.
- Texture: Crispy outside, tender onion inside.
- Appearance: Uniform shape and color, no soggy spots.

Common mistakes and how to fix them
- FORGOT to keep oil temperature steady → Use a thermometer and adjust heat as needed.
- DUMPED batter into hot oil all at once → Fry in small batches to prevent overcrowding and soggy bhajis.
- OVER-TORCHED the edges → Reduce heat to avoid burning and ensure even cooking.
- UNDER-COOKED in the middle → Fry longer or turn down heat to cook through without burning.
Quick kitchen fixes
- If oil smokes, lower the heat and add a sprinkle of salt to absorb excess moisture.
- When batter feels too runny, add a pinch more chickpea flour and mix thoroughly.
- Splash a little water into batter if it’s too stiff, then fold gently for better consistency.
- Patch a crackling hot oil by lowering the heat immediately and removing any burnt bits.
- Shield soggy bhajis by draining on paper towels and reheating briefly in a hot oven.
Prep, store, and reheat tips
- Prepare the onion slices and batter mixture a day ahead; store covered in the fridge to let flavors meld and batter firm up. Expect a slight increase in aroma and a denser texture after chilling.
- Refrigerate leftover cooked bhajis in an airtight container for up to 2 days. Reheat in a hot oven at 180°C / 350°F for 5-7 minutes until crispy and fragrant again.
- Frozen uncooked batter can be stored for up to 1 month. Thaw in the fridge overnight before frying. Expect a slightly softer batter initially, but crisp up well when fried.
- Reheat cooked bhajis on a baking sheet in the oven rather than microwave to maintain their crunch. They should shimmer with a slight crackle when ready, with warm, fragrant spices filling the air.
Top questions about onion bhajis
1. How thin should I slice the onions?
Use a sharp knife to get thin, even slices of onion. It helps them cook evenly and get crispy.
2. Can I use a different flour instead of chickpea flour?
Chickpea flour gives the bhajis their crunch and nutty flavor. You can substitute rice flour for a lighter texture, but it won’t be as crispy.
3. How do I know when the oil is hot enough?
Drop a small spoonful of batter into hot oil; if it sizzles and rises quickly, your oil is ready.
4. Why are my bhajis soggy or greasy?
Fry in small batches; overcrowding drops the temperature, making the bhajis soggy instead of crispy.
