Onion Dosa
Crispy, golden rice and lentil crepes loaded with finely chopped onions right on the griddle. As the dosa sizzles, the onions caramelize into the batter, creating a sweet, savory crunch that pairs perfectly with coconut chutney and a hot bowl of sambar.

Add 0.5 tsp salt and mix well with your hands.TIPYour hand's warmth helps kickstart the fermentation process. - rest
Ferment the batter overnight.
Cover the bowl loosely and leave in a warm place for 8 hours or overnight. The batter should almost double in volume and look bubbly.

Get the tawa ready.
1.Place the dosa tawa on medium-high heat.2.Once hot, sprinkle a few drops of water — they should sizzle and evaporate instantly.3.Optional: rub the tawa with a halved onion dipped in oil for a non-stick finish.TIPA properly hot tawa is the secret to a crispy dosa. - fry · ~3 min
Cook the onion dosa.
1.Pour a ladleful of batter in the center of the tawa.2.Quickly spread in a circular motion to form a thin, even crepe.3.Immediately sprinkle a generous handful of onion mixture over the surface.4.Drizzle 0.5 tbsp oil around the edges and a few drops on top.5.Cook on medium-high heat until the bottom is golden brown and crisp (2-3 minutes).TIPDo not spread the batter too thick — this dosa should be paper-thin and lacy. - fry · ~1 min
Flip confidently and crisp the onion side.
Once the base is crisp and releases easily from the tawa, use a flat spatula to flip the dosa. Press gently and cook for 30-45 seconds to caramelize the onions. The onion side should get crispy with browned edges.
TIPFlip only when the base is fully cooked, or it will tear. - serve
Serve immediately.
Fold the dosa into a triangle or a roll. Garnish with fresh coriander leaves. Serve piping hot straight from the tawa with coconut chutney and sambar.
TIPDosa waits for no one — serve it immediately to enjoy the crispness.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a well-seasoned cast iron or non-stick tawa for the crispiest results.
- 2Rub the hot tawa with a cut onion dipped in oil for an extra non-stick surface.
- 3Spread the batter thin and quickly; the onions will weigh it down slightly.
- 4Let the dosa cook undisturbed until the edges lift easily before flipping.
- 5For even caramelization, press the onion side gently with the spatula after flipping.
- 6Leftover batter keeps for 2-3 days in the fridge; stir before using as it may separate.
