How to Make Crispy Onion Bhaji: A Flavorful Vegan Appetizer Delight Recipe
Step 1: Heat the Oil
Start by pouring vegetable oil into a wok or deep pan, about 3 inches deep, and gently heat it on medium. The oil should reach around 180°C (350°F) to create that perfect frying environment for the bhajis. This temperature ensures crispiness without overheating and burning the batter.
Step 2: Prepare the Onion Mixture
In a large mixing bowl, combine thinly sliced onions, minced ginger, finely chopped green chilli, and all the aromatic spices including cumin, coriander, chilli flakes, and garlic salt. Then, add the gram flour, cornflour, and bicarbonate of soda. Stir everything together until the onions are thoroughly coated in these dry ingredients, creating a beautifully spiced base.
Step 3: Form the Batter
Gradually pour in water while stirring, working to form a thick batter that clings well to the onions. The consistency should be just right—thick enough to hold the shape of bhaji but not too dry. This balance will make frying easier and yield that perfect crunch everyone loves.
Step 4: Test the Oil
Before frying the entire batch, drop a tiny spoonful of batter into the hot oil. If it immediately sizzles and floats, you’re all set. This simple test helps avoid soggy or oil-logged bhajis and guarantees a crisp exterior from the first bite.
Step 5: Fry the Bhajis
Use a tablespoon to carefully form small, compact mounds of the batter and gently lower them into the hot oil in batches. To keep the bhajis perfectly crispy, avoid overcrowding the pan. Fry them for about 3-4 minutes, turning occasionally until they achieve a gorgeous deep golden brown color and crispness on all sides.
Step 6: Drain and Garnish
Remove the crispy bhajis with a slotted spoon and drain on kitchen paper to soak up excess oil. Once you have your golden batch, arrange them on a serving plate and sprinkle freshly chopped coriander over the top for a fresh finish. Serve with your favorite dipping sauce to complete the experience.

Garnishes
Fresh coriander is the classic choice to brighten these bhajis, adding a refreshing contrast to the rich, spiced batter. You can also add a pinch of chaat masala or a wedge of lemon on the side for an extra zing that awakens the taste buds beautifully.
Side Dishes
Crispy Onion Bhaji: A Flavorful Vegan Appetizer Delight Recipe pairs wonderfully with cool cucumber raita made from vegan yogurt or a tangy mango chutney. These sides provide a lovely balance and keep the palate refreshed between bites.
Creative Ways to Present
For a fun twist, serve the bhajis stacked on small skewers alongside a trio of dipping sauces—sweet chili, tamarind, and mint chutney. This not only makes for a visually inviting platter but also allows everyone to explore different flavor combinations as they enjoy the appetizer.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover crispy onion bhajis, cool them completely before storing. Place them in an airtight container and refrigerate for up to 2 days. While they may lose some crispness, they still maintain their lovely flavor for quick snacks later.
Freezing
You can freeze bhajis by placing them on a baking tray in a single layer, freezing until solid, then transferring into a freezer-safe bag or container. They’ll keep well for up to 1 month. Just remember to thaw before reheating for best results.
Reheating
To revive that wonderful crispness in leftover or frozen onion bhajis, reheat them in an oven or air fryer at 180°C (350°F) for about 8 minutes. This method avoids sogginess and restores their delightful crunch much better than microwaving.
FAQs
Can I make Crispy Onion Bhaji without green chilli?
Absolutely! Feel free to omit or reduce the green chilli if you prefer a milder taste. The other spices will still deliver plenty of flavor, and you can always add dipping sauces to control the heat.
Is gram flour gluten-free?
Yes, gram flour (besan) is naturally gluten-free, making this recipe perfect for anyone with gluten sensitivities or those following a gluten-free diet.
What can I use instead of bicarbonate of soda?
Bicarbonate of soda helps create a light and airy texture. If you don’t have it, baking powder can be used as a substitute, but use about three times the amount since they vary in potency.
Can I bake onion bhaji instead of frying?
While frying is traditional and gives the best crispness, you can bake them at 200°C (400°F) for 20-25 minutes, turning halfway through. The texture will be a bit different—less crunchy but still tasty.
What dipping sauces go well with these bhajis?
Sweet and sour or sweet chili sauces are classic pairings, but mango chutney, tamarind sauce, or a cooling vegan yogurt raita are excellent choices that complement the spices wonderfully.
