Air Fryer Onion Bajji - Crispy, Light, and Fast

Prep Time10 minutes
Cook Time12 minutes
Total Time22 minutes
Servings: 4 servings

Ingredients

  • 2 large onions (yellow or red), sliced into medium-thick rounds or half-moons
  • 3/4 cup gram flour (besan)
  • 2 tablespoons rice flour (for extra crispness)
  • 1/2 teaspoon baking powder (optional, for lightness)
  • 1/2 teaspoon turmeric powder
  • 1/2–1 teaspoon red chili powder (adjust to taste) or paprika for milder heat
  • 1/2 teaspoon carom seeds (ajwain) or 1/2 teaspoon cumin seeds
  • 1/2 teaspoon salt, plus more to taste
  • 1/4 teaspoon black pepper (optional)
  • 1 green chili, finely chopped (optional)
  • 2 tablespoons chopped cilantro (optional)
  • 1 teaspoon lemon juice (optional, brightens flavor)
  • 1/2 to 2/3 cup water (to make a thick, flowing batter)
  • 1–2 tablespoons oil (for brushing or spraying)
  • Chutney or ketchup for serving (mint chutney, tamarind chutney, or yogurt dip)

Instructions

  • Prep the onions: Peel and slice the onions into rounds about 1/4 inch thick. Separate the rings gently. If using half-moons, keep slices similar in size so they cook evenly.
  • Mix the dry ingredients: In a bowl, whisk besan, rice flour, baking powder, turmeric, chili powder, carom seeds, salt, and black pepper. This keeps the batter lump-free and evenly seasoned.
  • Add aromatics: Stir in chopped green chili and cilantro if using. These add fresh heat and herby notes.
  • Make the batter: Gradually add water, whisking until you get a thick, flowing batter—like pancake batter but slightly thicker. It should coat the back of a spoon without running off quickly. Add lemon juice if you like a hint of tang.
  • Preheat the air fryer: Set it to 375°F (190°C) for 3–5 minutes. A hot basket helps the batter set quickly and crisp up.
  • Coat the onions: Toss the onion slices in the batter. Shake off excess so you get a thin, even layer. Too much batter will make them cakey.
  • Oil the basket: Lightly grease the air fryer basket or line it with perforated parchment to prevent sticking. Do not over-grease; a thin coat is enough.
  • Arrange and oil: Place coated onions in a single layer without crowding. Lightly brush or spray the tops with oil for a golden finish.
  • Air fry, flip, and finish: Cook at 375°F (190°C) for 8–10 minutes. Flip or turn the pieces halfway and mist with a little more oil. Continue 4–6 minutes more until crisp and deep golden. Total time: 12–16 minutes, depending on thickness and your air fryer model.
  • Season and serve: Sprinkle a pinch of salt or chaat masala while hot. Serve immediately with mint chutney, tamarind chutney, or a quick yogurt dip.
