The right pan to simmer stock
Quick answer
To simmer stock, use a 12 quart disc-base stainless stockpot. Tall and narrow so evaporation is slow and the stock stays clear, and thin walls because nothing here needs heat retention.
The material properties are published. Which material suits which job is reasoned from those properties and from common kitchen practice.
| Material | Conductivity | Heat retention | Reactive | Suits this job |
|---|---|---|---|---|
| Tri-ply stainless clad | 237 W/m-K | medium | No | Workable, with compromises |
| Bare cast iron | 52 W/m-K | very high, because of mass rather than conductivity | Yes | Workable, with compromises |
| Carbon steel | 50 W/m-K | medium, well below cast iron because it is much thinner | Yes | Workable, with compromises |
| Enamelled cast iron | 52 W/m-K | very high | No | Workable, with compromises |
| PTFE nonstick | 237 W/m-K | low | No | Workable, with compromises |
| Bare or anodised aluminium | 237 W/m-K | low | Yes | Workable, with compromises |
| Copper, lined | 401 W/m-K | medium | No | Workable, with compromises |
| Plain stainless steel | 16 W/m-K | low | No | Workable, with compromises |

8 qtWhy disc-base stainless for this?
Tall and narrow so evaporation is slow and the stock stays clear, and thin walls because nothing here needs heat retention.
Disc-base stainless conducts at about 237 W/m-K and holds heat medium on the base, low on the walls. This is the honest difference from fully clad: the walls are plain thin stainless, so a sauce reduced up the sides can scorch where a clad pan would not. For a stockpot that difference barely matters, which is why disc-base stockpots are good value.
Why size matters as much as material
A 12 quart vessel gives room for the contents plus the headroom that stops it boiling over. Filling a pot close to the rim guarantees a mess as soon as it foams, and it makes the pot genuinely awkward to lift when full.
Crowding is the most common way this job goes wrong. Food releases moisture, and if there is not enough surface for that moisture to evaporate it pools and the food steams at roughly the boiling point of water instead of browning. Turning the heat up does not fix it, because the limit is evaporation rate rather than energy input.
What else will work, and what it costs you
Most of the other common materials will do this job to some degree, with a specific compromise each time. A thin conductive pan responds faster and loses temperature the moment cold food lands. A thick iron pan holds temperature and is slow to react when you want to pull the heat back. A coated pan releases food reliably and cannot be run at searing temperatures. Knowing which compromise you are making is more useful than owning the theoretically perfect pan.
This material is not reactive, so there is no constraint on acidic ingredients. Induction compatibility: yes. The bonded disc normally contains a magnetic steel layer specifically so the pan works on induction. Check with a magnet, since a few older disc pans do not.

Common questions
What is the best pan to simmer stock?
A 12 quart disc-base stainless stockpot. Tall and narrow so evaporation is slow and the stock stays clear, and thin walls because nothing here needs heat retention. Size matters as much as material here, because crowding causes more failed results than the wrong metal does.
Can I use a different material?
Yes, with a known compromise. Disc-base stainless is chosen here because tall and narrow so evaporation is slow and the stock stays clear, and thin walls because nothing here needs heat retention. Other materials will cook the food safely and will change the result: a thinner pan loses heat faster, a coated one cannot be run as hot, and a reactive one limits how long acidic ingredients can cook.
What size should the pan be?
12 quarts for a typical household, with headroom so it cannot boil over.
Does this work on induction?
Yes. The bonded disc normally contains a magnetic steel layer specifically so the pan works on induction. Check with a magnet, since a few older disc pans do not. A fridge magnet on the base settles it definitively: a firm grip across the whole base means it will work, a grip only in the centre means uneven heating, and no grip means it will not heat at all.
How hot can this pan go?
The material is good to about 500F. Cuisinart publishes 500F oven safe for the Chef's Classic stainless line. Glass lids are usually rated lower than the pan. The real ceiling for any assembled pan is the lowest of its cooking surface, its handle and, when covered, its lid, and the handle is very often the lowest of the three.
