What is an Onion Bhaji? Unravelling the Popular Indian Snack
Onion bhajis are a popular Indian snack made from a mixture of sliced onions, spices, and gram flour, deep-fried until crispy and golden brown. They are often served as an appetizer or snack with chutneys or sauces, and are enjoyed across the Indian subcontinent as well as in other parts of the world. The origins of onion bhajis can be traced back to the Indian subcontinent, where they have been a popular street food snack for centuries. The word "bhaji" in Hindi means "vegetable fritter," and the dish has evolved over time to include a variety of vegetables in addition to onions, such as potatoes, spinach, and eggplant.
In recent years, onion bhaji recipes have gained popularity in other parts of the world, especially in the UK, where air fryer onion bhaji is a common variation. Some variations of the dish may include different spices or ingredients, such as ginger, garlic, or chili peppers.
Preparation Details:
Preparation time: 20-30 minutes
Cooking time: 15-25 minutes (for 3-4 batches)
This recipe makes: 15 Bhajis
Crafting the Perfect Bhaji: Ingredients You'll Need
4 medium white onions, cut in half and sliced thinly
1 green chili, finely sliced (seeds removed if desired)
1 medium potato, peeled and cut into thin matchsticks
1 tbsp garlic and ginger paste (or 2 cloves of garlic and a thumb-sized piece of ginger, finely grated)
A small handful of fresh coriander leaves, finely chopped
1tsp salt
1tsp mild chili powder
1tsp ground coriander
1tsp ground turmeric
1tsp ground cumin
1 large egg (optional - skip for vegan version)
175 grams (1.1/4 cups) of gram flour (chickpea flour)
Vegetable oil for deep-frying (enough to fill a large pot to a depth of at least 2 inches)

Crafting the Crispy Delight: Steps to Perfecting Your Onion Bhajis
1. Preheat a deep fat fryer or a small pot filled with oil to 170C (340F). To check the oil temperature, use an electric probe.
2. In a large mixing bowl, combine sliced onions with potato matchsticks, green chilli, garlic ginger paste, fresh coriander, salt, and spices. Mix well until all onions are evenly coated.
3. Crack one egg into the bowl and mix it thoroughly with the onion mixture until all ingredients are well combined.
4. Gradually add the chickpea flour to the bowl, stirring constantly until there are no visible signs of dry flour remaining in the mixture (Consider resting the onion bhaji mix for about 10-15 minutes before frying. This allows the flavours to meld and the gram flour to absorb moisture, resulting in a better texture).
5. To protect your hands, wear gloves and take a small amount of the bhaji mix, shaping it into a ball in your hands without compressing the mixture. Carefully place the ball into the hot oil.
6. Cook the bhajis until they are golden-brown, flipping them over once to cook the other side until it is also golden-brown. Use a spider strainer or tongs to remove the bhajis from the oil and place them onto a kitchen paper to drain any excess oil.
7. Repeat the process until all of the bhajis are cooked. Serve them immediately or reheat them in the oven before serving.
Making Air Fryer Onion Bhaji: A Healthier Twist
If you're looking to make onion bhaji in an air fryer, follow the same preparation steps for the onion bhaji mix. Instead of deep frying, place the bhajis in the air fryer and cook at 180°C for 15-20 minutes or until golden brown, turning halfway. Ensure they are spaced out evenly to allow for proper air circulation. This will give your air fryer onion bhaji a crispy finish.

Ingredients for Perfect Chilli Sauce:
1 red chilli, seeds removed and sliced
1 red bell pepper, diced
1 garlic clove
juice of half lemon
50ml of water
1/4tsp of salt
1/4tsp of sugar
1/4tsp of ground cumin
Mastering the Art: Steps to Achieve the Perfect Chilli Sauce
Blend It Up: Add all ingredients to your blender and process until you achieve a smooth chilli sauce consistency.
Let It Settle: Pour the sauce into a bowl, allowing any trapped air bubbles to rise.
Ready to Serve: After the bubbles have dissipated, transfer the sauce to your preferred serving dish.
Unlocking the Secrets: Pro Tips for Bhaji Perfection
Slice Like a Pro: Whether you're using a mandoline or a trusty sharp knife, aim for thin, even onion slices. This not only ensures uniform cooking but also gifts your bhajis with that crave-worthy texture.
Banish Bitterness: Give your thinly-sliced onions a refreshing cold water bath for about 10 minutes. This simple step draws out any bitterness, leaving you with tender, sweet onions ready to shine in your bhaji mix.
Potato Perfection: Speed up cooking and achieve evenness by shredding your potatoes into fine matchsticks. Whether you're team food processor or team grater, the goal is uniformity.
Spice It Right: Freshness is the key to a flavour-packed bhaji. Opt for whole spices and grind them just before use. This releases their aromatic oils, ensuring every bhaji is a flavour explosion.
Bind & Fry: Stir in the egg just before you're set to fry, binding your mixture beautifully. And speaking of frying, always monitor your oil's temperature. Aim for that sweet spot of 170°C/340°F. Too hot, and you risk burnt exteriors with uncooked centres. Too cool, and you're in for an oily affair.
Batch Bliss: Resist the urge to overcrowd your pot. Fry your bhajis in small batches, ensuring each one cooks evenly and retains its shape.
Crispy Finish: Once golden, let your bhajis rest on a paper towel. This absorbs any extra oil, ensuring your bhajis remain delightfully crispy and light when served.
