What a Donabe Does That Metal Cannot
A donabe is a Japanese earthenware pot, most famously made from Iga clay — a porous, ancient lakebed clay fired at high temperature. The porosity is functional: it gives the pot low thermal conductivity and high heat retention, so it warms slowly and evenly and then holds that heat for a long time after the flame goes out.
That is what makes it right for tabletop cooking. A nabe hotpot brought bubbling to the table stays at a gentle simmer for the length of a meal without any heat source under it, which no metal pot does. It is also why donabe-cooked rice has a reputation that survives the existence of excellent rice cookers — the slow, even heat and the sustained residual heat during resting produce a distinct texture.
The trade-off is fragility and specificity. Clay cannot take thermal shock, cannot go on induction without help, and needs seasoning before first use. It is a specialised pot, and it rewards being used for what it is good at rather than pressed into general service.
Types and What They Are For
| Type | Purpose | Notes |
|---|---|---|
| Standard nabe donabe | Hotpot, shabu-shabu, sukiyaki | Wide, shallow, lidded — the classic |
| Kamado-san style rice donabe | Rice | Double lid, tall walls, dedicated |
| Tagine-style donabe | Steaming, mushi-nabe | Domed lid, condensation returns |
| Ameiro / glazed donabe | General use | Fully glazed, less porous, easier care |
| Small individual donabe | Single portions | Tabletop presentation |
| Induction-compatible donabe | Any — on induction | Bonded metal base plate |
Donabe and Induction
Clay is not ferromagnetic, so a traditional donabe will not work on an induction hob at all. This catches out a lot of buyers with modern kitchens.
Two options exist: donabe manufactured with a bonded metal base plate specifically for induction, or a magnetic interface disk under a traditional pot. The disk works and reintroduces exactly the uneven, laggy heating that a donabe exists to avoid, so an induction-specific model is much the better answer if induction is your hob.
Which Donabe Should You Buy?
The Hotpot Pot
- Wide, shallow, lidded donabe around 2–3 litres
- Serves three to four at a table
- Goes from hob to table and stays hot through the meal
- The most versatile first donabe
The Rice Obsessive
- Double-lidded, taller walls, built for rice specifically
- Distinct texture and a proper crust at the base
- Roughly twenty minutes plus resting, no timer or programmes
- A dedicated pot, not a general-purpose one
The Low-Maintenance Owner
- Fully glazed inside and out, far less porous
- No seasoning ritual required before use
- Easier to clean and less prone to absorbing odours
- Less of the characteristic porous-clay behaviour
The Modern Hob
- Bonded metal base plate designed for induction
- Works properly rather than through a workaround disk
- Costs more than a traditional pot
- Check the specification explicitly — most donabe are not compatible

Classic Nabe Donabe (2–3L)
The wide, shallow, lidded pot that defines the category. Big enough for a hotpot for three or four, and it goes straight from the hob to the table where it holds a gentle simmer for the length of a meal with no heat under it.
Best for: Hotpot, shabu-shabu, sukiyaki and anyone buying their first donabe.
Double-Lid Rice Donabe
Built specifically for rice, with taller walls and a double lid that controls pressure and steam. The result has a texture and base crust that a rice cooker does not produce, at the cost of needing your attention for twenty minutes.
Best for: Anyone who cares enough about rice to cook it actively rather than pressing a button.
Induction-Compatible Donabe
A donabe manufactured with a bonded metal base so it works properly on an induction hob rather than through an interface disk. Check this specification explicitly, because the overwhelming majority of donabe are not induction compatible.
Best for: Anyone with an induction hob who wants a donabe that works as intended.
Korean Ttukbaegi
The Korean earthenware equivalent: smaller, thicker-walled individual pots that arrive at the table still violently bubbling. Ideal for sundubu jjigae and single-portion stews, and considerably cheaper than a donabe.
Best for: Individual portions, Korean stews, and a low-cost way to try clay pot cooking.
Heat Diffuser Plate
A metal diffuser between a gas flame and the pot base spreads heat and prevents the concentrated hot spot that causes cracking. On any powerful burner this is cheap insurance on an expensive and fragile pot.
Best for: Anyone using a donabe on a high-output gas burner.
Seasoning a New Donabe
Unglazed and partially glazed donabe need seasoning before first use, and the traditional method uses starch to seal the porous clay. Cook a thin rice porridge — okayu — in the pot: roughly a quarter cup of rice to four cups of water, brought slowly to a simmer, cooked for about an hour, then left to cool completely in the pot before discarding.
The starch penetrates the pores and seals microscopic channels, which strengthens the pot and reduces absorption of flavours and liquids. Some makers recommend repeating this annually or whenever the pot has been through heavy use. Fully glazed donabe do not require it — check the manufacturer's instructions rather than assuming.
The Four Rules That Prevent Cracking
Never heat it empty or nearly empty. Clay needs the thermal buffer of contents. A dry donabe on a flame cracks quickly.
Never go from hot to cold. No cold water into a hot pot, no hot pot onto a wet or cold surface, no refrigerator straight to a burner. Thermal shock is the primary cause of failure.
Dry the outside before heating. Moisture trapped in the porous base turns to steam and cracks the pot from inside.
Start low and build. Bring the heat up gradually rather than starting on high, and use a diffuser on a powerful gas burner.
Buy a classic 2–3 litre nabe donabe if you want one clay pot — it handles hotpot, stews and tabletop cooking, and the residual heat that keeps a meal simmering at the table is the thing metal genuinely cannot do. Buy a rice donabe only as a second, dedicated pot. If you cook on induction, check for a bonded base explicitly, because most donabe will simply not work. And season a new unglazed pot with rice porridge before it touches anything else — and never, ever heat it dry.

Frequently Asked Questions
Do I need to season a new donabe?
Unglazed and partially glazed donabe, yes. The traditional method is to cook a thin rice porridge — okayu — in the pot: about a quarter cup of rice to four cups of water, simmered slowly for an hour and left to cool completely in the pot. The starch seals the porous clay, strengthening the pot and reducing absorption. Fully glazed models generally do not need it; follow the manufacturer's instructions.
Can a donabe be used on induction?
Not a traditional one — clay is not ferromagnetic, so an induction hob will not register it at all. Donabe manufactured with a bonded metal base plate for induction do exist and are the right answer if induction is your hob. A magnetic interface disk under a traditional pot works after a fashion and reintroduces exactly the uneven, laggy heating a donabe exists to avoid.
Why did my donabe crack?
Almost always thermal shock or dry heating. Never heat a donabe empty or nearly empty, never put cold liquid into a hot pot or a hot pot onto a cold wet surface, dry the outside thoroughly before heating so trapped moisture cannot turn to steam inside the clay, and bring the heat up gradually rather than starting high. A diffuser plate helps on a powerful gas burner.
What is the difference between a donabe and a Korean ttukbaegi?
Both are earthenware pots that retain heat well and go from heat to table. A donabe is typically wider and shallower, sized for communal hotpot, and made from Iga or similar porous clay. A ttukbaegi is smaller, thicker-walled and usually a single-portion vessel that arrives at the table still bubbling — ideal for jjigae, and considerably cheaper.
Is donabe rice actually better than a rice cooker?
Different rather than strictly better. A donabe produces a distinct texture and a base crust that comes from slow, even clay heat and sustained residual heat during resting. A good rice cooker is more consistent, requires no attention and handles timing automatically. The donabe rewards active cooking; the rice cooker rewards not thinking about it.
