Why cast iron still matters
A well-cared-for cast iron pan can outlast the person who bought it. Unlike nonstick pans, whose lifespan is limited by the coating, cast iron gets better with use: every cook adds another layer to its seasoned surface.
What to check before buying
- Weight relative to diameter: a 10-inch pan that feels too light usually has thin walls that heat unevenly.
- Cooking surface: older and some artisan-made pans have a smooth surface; many current budget models are rougher out of the box — not a defect, but it affects how long it takes to build a good seasoning.
- Handle and helper handle: on pans 12 inches or larger, a helper handle on the opposite side makes a real difference when moving a hot pan.
- Factory seasoning: most pans come pre-seasoned with vegetable oil, but that initial layer is thin — it doesn't replace the seasoning you'll build yourself through use.
A nuance worth knowing
Price doesn't always track quality in cast iron. More affordable foundries with thick walls and decent initial seasoning can perform just as well as premium brands for everyday home cooking.
An example that fits these criteria
If you're looking for a versatile piece beyond the traditional skillet, a flat-bottom cast iron wok is a good way into cast iron: the flat bottom makes it compatible with induction, glass-top, gas, and electric stoves — unlike traditional round-bottom woks, which really only work well over strong gas flame — and since it has no nonstick coating, it develops the same kind of natural seasoning as a cast iron skillet.
How to care for it the first few weeks
After each use, wash with hot water and a brush (skip soap for the first few weeks if you want to speed up seasoning), dry it completely on the stove over low heat, and rub in a very thin layer of neutral oil with a cloth before storing. This simple cycle is what actually builds the natural nonstick surface.
Signs it needs re-seasoning
If food starts sticking more than usual, or you see rust spots after accidentally storing it damp, it's not ruined — a full re-season (several layers of oil baked on at high heat) usually brings it back to its best state.
