The kadhai is the workhorse of the Indian kitchen. It fries puris and pakoras, cooks sabzi, makes halwa, and handles everything from a quick tadka to a big batch of chole. Because it faces high heat, oil and stirring every day, the material you choose makes a big difference to how well it cooks and how long it lasts.
The four main materials
| Material | Best for | Pros | Cons | Induction? |
|---|---|---|---|---|
| Iron (sheet or cast) | Deep frying, dry sabzis, bhuna, high heat | Cheap, very durable, gets better with use, naturally low-stick when seasoned | Heavy; rusts if left wet; needs seasoning; not for long-cooked sour dishes | Yes, if the base is flat |
| Stainless steel (tri-ply or sandwich base) | Everyday cooking, frying, gravies, sour dishes | Non-reactive, very durable, easy to scrub, no coating to wear out | Food can stick until you learn the heat; costs more; thin steel heats unevenly | Yes, with a magnetic base |
| Aluminium (plain) | Budget cooking, quick sabzis | Light, cheap, heats fast | Dents, discolours, reacts with acidic food; shorter life | Only with an induction base |
| Hard-anodised aluminium | Gravies, everyday cooking | Non-reactive surface, heats evenly, tougher than plain aluminium | Usually not dishwasher-safe; needs gentle cleaning | Only with an induction base |
| Non-stick coated | Low-oil sabzis, eggs, reheating | Food releases easily, easy to clean, needs little oil | Coating wears out; needs wooden or silicone spatulas; not ideal for very high heat | Only with an induction base |
Iron kadhai
The traditional choice, and still one of the best for frying. Iron handles very high heat without damage, and once seasoned it develops a naturally slick surface.
- Sheet iron (the common black kadhai) is lighter and heats quickly.
- Cast iron is thicker and heavier, holds heat longer and keeps oil temperature steady, but it’s brittle: it can crack if dropped or if very cold water hits it while hot.
Care: wash, dry completely on the flame and wipe a thin layer of oil on before storing, especially in the monsoon. Avoid cooking very sour dishes (tomato-heavy gravies, tamarind, kadhi) for long, and never store food in it, as acid strips the seasoning and can give food a metallic taste and dark colour. Our cast iron tawa seasoning guide explains how to season and fix rust; the same method works for a kadhai.
Stainless steel kadhai
A good all-rounder that will last decades. Plain thin steel heats unevenly and scorches, so look for a tri-ply or sandwich base (a layer of aluminium or copper bonded inside steel), the same as we recommend in our pressure cooker buying guide.
- Fully clad (tri-ply body): the layers run up the sides too. Heats evenly all over; costs more.
- Sandwich base only: the bottom has the extra layer, the sides are single steel. Cheaper and fine for most cooking.
Tip to reduce sticking: heat the empty kadhai on medium for a minute, add oil, let it heat, then add food. Don’t move food straight away; it often releases once it browns. For burnt-on stains, soak with baking soda and warm water before scrubbing.
Aluminium and hard-anodised kadhai
Plain aluminium is the cheapest option and heats very quickly, which is why it’s common in many homes. But it can react with acidic food like tomatoes, tamarind and lemon, dents easily and wears over time. If you use one, don’t store sour food in it.
Hard-anodised aluminium has a treated surface that is harder and non-reactive. It heats evenly and suits gravies and everyday sabzis. Clean it with a soft sponge and mild soap; harsh scrubbers and dishwashers can damage the surface.
Non-stick kadhai
Non-stick coatings let you cook with very little oil and clean up easily. They’re good for sabzis, poha, upma and reheating. The trade-off is that the coating wears out, usually within a few years depending on use and care.
- Cook on low to medium heat; don’t heat it empty on high.
- Use wooden or silicone spatulas, never metal.
- Hand-wash with a soft sponge once it has cooled.
- For very hot tadka, a small separate iron or steel tadka pan is kinder to your coating.

Size, base and handles
| Household / use | Suggested size (top diameter) |
|---|---|
| 1–2 people, small sabzi | About 20–22 cm |
| 3–5 people, everyday cooking and frying | About 24–28 cm |
| Large families, festivals, bulk frying | 30 cm and above |
Sizes vary by brand, and some list capacity in litres instead. A deeper kadhai is safer for frying because oil is less likely to splash over.
- Base: a flat base sits steadily on induction and modern gas stoves. Round-bottomed kadhais need a stand ring on some burners and won’t work on induction.
- Thickness: a heavier, thicker base heats more evenly and is less likely to warp.
- Handles: check that they’re riveted firmly. Metal handles get hot, so keep a cloth or holder nearby. Bakelite-type handles stay cooler but shouldn’t go near a high flame or in the oven.
- Lid: useful for steaming vegetables and simmering. Some kadhais include one; many don’t.
Which one should you buy?
| If you… | Choose |
|---|---|
| Deep fry often and don’t mind a little maintenance | Iron |
| Want one kadhai that does everything and lasts decades | Stainless steel with a sandwich base |
| Cook mostly low-oil sabzis and want easy cleaning | Non-stick or hard-anodised |
| Are on a tight budget and cook mostly on gas | Iron (cheap and long-lasting) or plain aluminium |
| Use an induction cooktop | Iron with a flat base, or steel with a magnetic base; see our induction cookware guide |
Many Indian homes end up with two kadhais: an iron or steel one for frying, and a non-stick one for everyday sabzis.
Bottom line
Choose iron for frying on a budget, stainless steel with a sandwich base for a low-maintenance kadhai that lasts decades, and non-stick or hard-anodised for low-oil everyday cooking. Pick a flat, heavy base in the right size, and check it works on induction if you use one.
Frequently asked questions
Which kadhai is best for deep frying?
An iron or heavy stainless steel kadhai with a thick base. Both handle high heat well, hold a steady oil temperature and last for years. Iron needs seasoning and drying; steel with a sandwich base is easier to look after.
Is an iron kadhai good for health?
Cooking in iron may add small amounts of iron to food, which is often mentioned as a benefit. The amount varies a lot with the dish and the pan, so don't rely on it to treat a deficiency. Avoid cooking very sour dishes for long in it or storing food in it.
Can I use an aluminium kadhai on induction?
Not a plain one. Aluminium isn't magnetic, so induction cooktops can't heat it. Some aluminium and hard-anodised kadhais have a steel plate fixed to the base for induction; check for the induction symbol or do a magnet test.
Can I deep fry in a non-stick kadhai?
Some non-stick kadhais are sold for frying, but high heat over long periods wears the coating faster. For regular deep frying of puris, pakoras and bhaturas, iron or steel lasts much longer. Keep non-stick for low-oil sabzis and gentle cooking.
