Choosing
Dutch ovens: iron, aluminum, or the one whose lid is a pan
A Dutch oven is a heavy lidded pot for slow cooking, and the material changes what it is for. Bare cast iron goes on a fire; enamelled iron does not need seasoning; cast aluminum is a third of the weight and holds heat worse; stainless is the one that also boils pasta. The right answer depends on where you intend to cook.
By Jean-Benoit Buisson
Five pots, four materials, and four different jobs.
For bread and the hob
The Topbooc 26 cm (10.2 in), 5 liters of enamelled cast iron, stated for bread baking, and compatible with induction, ceramic and gas. Enamel means no seasoning and no rust, and it means treating it gently — enamel chips.
For a fire
The BBQ-Toro rectangular cast iron, 10.5 liters total: 7.5 in the pot and 3 in the lid, 40 × 30.5 cm (15.7 × 12 in), pre-seasoned. The lid holding three liters makes it a second pan, and the 40 cm (15.7 in) footprint suits embers rather than a hob ring.
For lifting
The Karcher 42 × 25.5 × 12 cm (16.5 × 10 × 4.7 in), 8.7 liters, cast aluminum with a PTFE coating and a lid that doubles as a pan. Far lighter than iron, and not for a fire.
For everything else
The WMF 41 × 28.5 × 18 cm (16.1 × 11.2 × 7.1 in) with a 30.5 × 18 cm (12 × 7.1 in) base, 8.5 liters, uncoated Cromargan 18/10, with a lid that doubles as a pan. Stainless means it also boils, and it publishes more dimensions than anything else here.
The cheapest way in
The GSW cast aluminum with a multi-layer nonstick on an extra-strong FerroTherm base, lid included, induction compatible.
The question that decides it
Where will you cook? Fire means bare iron. Hob and oven means anything. Bad wrists mean aluminum.
The questions that come in
Enamelled or bare cast iron?
Enamelled needs no seasoning and can hold acidic food indefinitely; bare iron must be seasoned and dried, and can go in a fire. Enamel chips if dropped; seasoning can be rebuilt. They are different tools.
Can I bake bread in one?
That is one of the classic uses — the lid traps steam from the dough, which is what gives a crust. The Topbooc here states bread baking explicitly.
Is cast aluminum a compromise?
It is lighter and it heats faster; it holds heat less well, which is exactly what a Dutch oven is for. With a coating it also cannot go over a fire. For a hob and an oven it is perfectly good and much easier to lift.
What size should I buy?
Size it to your usual batch. The largest models are heavier than most people expect and sit half empty for everyday cooking.
How do I avoid chipping the enamel?
Avoid knocks, metal utensils and thermal shock. Letting it cool before washing prevents most enamel damage.
How long does one last?
Cared for, indefinitely; that is the point of the material. Neglected, bare iron rusts within hours and enamel chips quickly.
Is the weight really a problem?
For some people yes, and it is worth lifting one full before buying. That weight is the daily reality of using it.
Can I use it on any hob?
Cast iron works on every hob type, including induction. On glass surfaces lift it rather than sliding it, because the weight scratches easily.
