What’s Different?
- No oil used at all — not in batter, not in cooking, not in the masala.
- Uses steam-based cooking and nonstick or cast-iron tawa for a clean, oil-free dosa.
- Potato filling is made with very minimal ingredients but still tastes good.
Ingredients
For Ragi Dosa Batter
- ½ cup ragi flour
- ¼ cup rice flour (or wheat flour for softer dosas)
- Water as needed
- Salt to taste
- ½ tsp cumin seeds
- Optional add-ins: chopped onion, coriander leaves, ginger
This version is flexible — you can skip onions/chillies if you want it lighter.
For No-Oil Potato Filling
- 3 medium potatoes, boiled & peeled
- 1 medium onion (finely chopped or sliced)
- 1 green chilli (optional, finely chopped)
- ½ tsp turmeric
- Few curry leaves
- Salt to taste
- Splash of lemon juice (optional)
- A handful of chopped coriander (optional)

How to Make (Oil-Free Method)
1. Make the Ragi Batter
- Mix ragi flour, rice flour, salt and cumin.
- Add water slowly and whisk until smooth.
- Make the batter slightly thin — thin batter spreads easier without oil.
- Rest for 10 minutes.

2. Prepare Oil-Free Potato Masala
This is the tricky part — but very doable.
- Heat a nonstick pan on low.
- Add onions, chillies and curry leaves.
- Sprinkle 2–3 tablespoons of water and cover with a lid.
- Let the onions soften — add more water if needed but don’t drown them.
- Once soft, add turmeric and salt.
- Crumble boiled potatoes into the pan.
- Add 1–2 more tablespoons water to help mix everything.
- Stir well on low heat for 2 minutes.
- Add lemon juice or coriander if you like.
The potato masala will be soft, comforting and completely oil-free.
3. Cook No-Oil Ragi Dosa

- Heat a nonstick or well-seasoned cast-iron tawa on medium-high.
- When hot, sprinkle a few drops of water to test — they should sizzle.
- Pour a ladle of batter and spread gently in circles.
- Do NOT add oil.
- Let it cook until the edges start lifting up naturally.
- Place some potato masala in the center.
- Fold the dosa gently.
Because the batter is light and the pan is hot, the dosa will release on its own without needing oil.
Extra Tips for Success
- Preheat well — this is the secret to oil-free dosas not sticking.
- If using cast-iron, rub a cut onion on the surface before cooking — helps prevent sticking.
- Make the batter a bit thinner than usual → spreads better without oil.
- Cook on medium-high heat, not low.
- If a dosa sticks, scrape it off and heat the tawa more before the next one.
