Cast-Iron Skillet

Heat-retaining pan that delivers the deepest sear and crust

A thick iron pan that holds heat like nothing else, giving steaks, cornbread, and crusts a deep, even sear. A well-kept seasoning layer makes it naturally nonstick. Dry it on the stove after washing and wipe with a film of oil.

Cast iron is the pan that outlives its owner. A single thick casting of iron, it stores an enormous amount of heat and gives it back steadily, which is why nothing sears a steak, bakes cornbread, or crisps a skin-on chicken thigh quite like it. The trade-off is that iron is slow to heat and slow to respond, so it rewards preheating and punishes impatience. Its secret is the seasoning: a thin layer of polymerized oil baked onto the surface that becomes naturally, improbably nonstick the more you cook in it. Maintained well — dried over heat, wiped with oil — a cast-iron skillet is a heirloom that gets better with every meal.

Types & varieties

Pre-seasoned bare iron

Ready to use out of the box; the seasoning improves with cooking.

Smooth-machined (vintage style)

Polished interior, slightly slicker than the pebbly modern texture.

Enameled cast iron

Glass coating means no seasoning and it handles acidic foods — but loses the bare-iron sear.

Enameled Cast Iron Skillet

Cast iron coated in a glassy enamel that needs no seasoning and won't react with acids, so you can simmer tomato or wine sauces and deglaze without harming a finish.

Seasoning and re-seasoning

To season from scratch or revive a dull pan: scrub it clean and dry it completely, rub an ultra-thin coat of neutral oil over every surface (wipe it back until it looks almost dry — excess oil goes gummy and sticky), then bake it upside down at around 450–500°F for an hour and let it cool in the oven. Repeat for a deeper finish. Each time you cook with fat, you reinforce the layer.

Use a thin coat of high-smoke-point oil; too much oil makes a tacky surface
Bake upside down on foil to catch drips, oven hot, then cool inside
If food starts sticking or the pan looks gray and dull, it's time to re-season

Daily care (the real rules)

A little dish soap is fine on modern seasoning — the 'never use soap' rule is outdated. What truly matters: don't soak it, don't put it in the dishwasher, and always dry it completely. The fastest way to dry is to set it back on a warm burner for a minute, then wipe a few drops of oil around the interior with a paper towel. Stored damp, iron rusts; stored dry and lightly oiled, it lasts forever.

Scrub stuck-on bits with coarse salt or a chainmail scrubber, not steel wool that strips seasoning
Dry over heat immediately — never air-dry or leave it wet in the rack
Avoid long simmers of very acidic sauces in bare iron; they can dull the seasoning and taste metallic

Common uses

Searing steaks and burgers with a deep crustBaking cornbread, skillet cookies, and Dutch babiesCrisping skin-on chicken thighs and fishShallow-frying and deep-fryingRoasting and oven-to-table dishesCooking over a campfire or grill

Tips & pitfalls

Preheat for several minutes — patience is the whole technique with iron
The handle gets blazing hot; keep a thick mitt or handle cover within reach at all times
Don't deglaze a blazing-hot cast-iron pan with cold liquid or run it under cold water — sudden thermal shock can crack or warp the casting; let it ease down first, or use warm liquid
Rust isn't fatal: scrub it off, re-season, and the pan is good as new
Start a steak or chicken on the stovetop and finish it in the oven without changing pans
