Onion Bajji is a beloved Indian snack with crispy texture and bold, aromatic spicing. This popular vegetarian treat is a family tea-time favorite and a staple at celebrations and gatherings.
Peel and thinly slice the onions into rings; set aside for even coating.
In a mixing bowl, combine chickpea flour, rice flour, baking soda, red chili powder, cumin seeds, turmeric powder, and salt.
Gradually add water while whisking to create a thick, lump-free batter that can coat the onions evenly.
Heat the vegetable oil in a deep pan over medium-high heat (350°F) until a small drop of batter sizzles immediately.
Dip onion rings individually into the batter, ensuring each is well coated, and carefully slide them into the hot oil in batches—do not overcrowd the pan.
Fry each batch for about 3–4 minutes, turning occasionally, until the bajjis are golden and crisp. Adjust heat as needed to maintain steady frying without burning.
Remove onion bajjis with a slotted spoon and drain on paper towels. Serve hot with chutney or ketchup.
