🧅 Ingredients for Onion Bhajis

You will need:

• 2 large onions, thinly sliced
• 120g gram flour (chickpea flour)
• 1 teaspoon ground cumin
• 1 teaspoon ground coriander
• ½ teaspoon turmeric
• ½–1 teaspoon chilli powder (to taste)
• Salt, to taste
• Water (to bind)
• Oil, for frying

Optional additions: fresh coriander, grated ginger, garlic, garam masala.

🍳 How to Make Onion Bhajis

1️⃣ Prepare the Onions

Place the sliced onions in a bowl, sprinkle with salt, and mix well. Leave for 5–10 minutes until they soften and release moisture.

2️⃣ Add the Dry Ingredients

Add the gram flour and spices to the onions. Mix well so the onions are coated.

3️⃣ Add Water

Add a small amount of water gradually, mixing until you have a thick, sticky batter that clings to the onions. Do not make it runny.

4️⃣ Heat the Oil

Heat oil in a deep pan over medium heat. The oil is ready when a small piece of batter sizzles immediately.

5️⃣ Fry the Bhajis

Drop spoonfuls of the mixture into the hot oil. Fry in batches for 3–4 minutes, turning occasionally, until golden brown and crisp.

6️⃣ Drain

Remove the bhajis and drain on kitchen paper.

🔥 Tips for Perfect Onion Bhajis

• Slice onions thinly for even cooking
• Use minimal water — onions release moisture
• Fry at medium heat to cook through without burning
• Don’t overcrowd the pan
• Season well

For extra crispness, let the mixture rest for 5 minutes before frying.

🌿 Variations to Try

• Extra crispy bhajis – add a tablespoon of rice flour
• Milder bhajis – reduce chilli and add more onion
• Herby bhajis – add chopped coriander
• Baked bhajis – bake at 200°C (180°C fan) for 20–25 minutes, turning halfway

🍽️ What to Serve with Onion Bhajis

Onion bhajis are perfect with:

• Mint yoghurt
• Mango chutney
• Raita
• As a side with curry

They’re best served hot and fresh.

🌿 Final Thoughts

Homemade onion bhajis are easy to make and packed with flavour. With the right balance of spices, minimal batter, and careful frying, you’ll get crisp, golden bhajis every time.

Once you try them homemade, takeaway versions rarely compare.
