Cast iron, answered

A classic 10 to 10.25-inch Lodge, for about $25. It's made in the USA, ships pre-seasoned, is oven-safe to any temperature, and cooks the same food as pans costing ten times more. You pay up only for a lighter body, a smoother surface or a better handle — real comforts, not better cooking.

Not for cooking. Cast iron is cast iron, so a $250 heirloom pan sears and bakes like a $25 Lodge. The premium buys a machined-smooth surface, less weight and a nicer handle. Buy up only if one of those specifically bothers you.

Yes. The 'never use soap' rule dates from when soap contained lye, which stripped seasoning. Modern dish soap won't harm a well-seasoned pan. What actually causes trouble is soaking the pan, leaving it wet, or putting it in the dishwasher.

Dry it completely after washing — the single most important step — ideally by setting it on a warm burner for a minute, then rub in a very thin coat of oil before storing. Rust comes from moisture left on bare iron, not from water itself.

Almost certainly not. Scrub the rust off with steel wool (a short diluted-vinegar soak helps with heavy rust), wash and dry it, then re-season two or three times. Even a badly neglected pan usually comes back completely. See our rust-removal guide.

Seasoning is a layer of oil that has been baked onto the iron until it polymerizes into a hard, slick, plastic-like film bonded to the metal. It's what makes the pan release food and resist rust. It's built up with thin coats of oil and heat, not bought as a coating.

For a pan you cook with regularly, rarely — normal cooking with a little fat maintains it. Do a full re-season if the surface looks dull or patchy, food starts sticking, or you've scrubbed hard to remove rust or stuck-on food.

For a dutch oven, enameled: it needs no seasoning and handles acidic braises like tomato and wine. For a skillet, bare cast iron: it's cheaper and builds a natural non-stick surface. Many kitchens end up with one of each.

In enameled cast iron, freely — that's a main reason to own one. In bare cast iron, a quick tomato dish is fine, but a long acidic simmer can strip seasoning and pick up a metallic taste, so it's better done in enamel or stainless.

Yes. Cast iron is solid ferrous iron, which is exactly what induction needs, so both bare and enameled cast iron work on induction cooktops.

A 5.5 to 6-quart round dutch oven is the do-everything size — it braises for a family of four and fits a round loaf of bread. Go smaller (3.5–4.5 qt) for one or two people, and 7 quarts or more only for big-batch cooking. See our dutch oven size guide.

For cooking, effectively yes. A Lodge or Tramontina enameled pot braises the same food as a $300 Le Creuset. The extra money buys tougher, more chip-resistant enamel, a lighter body, a light interior that makes browning easy to judge, and resale value.

Cast iron is thick, heavy and holds heat well — best for searing and oven work. Carbon steel is thinner, lighter and more responsive — best for stovetop cooking and anyone who wants a lighter pan. Both need seasoning. Our comparison breaks down which suits which cook.

We tell you plainly that we haven't cooked in them, and we don't pretend otherwise. Instead we compare the manufacturers' published specs, model the ten-year cost of ownership, and cite every source — a method you can reproduce and check. It's all on our methodology page.

No. We accept no sponsorships and no free products for coverage. The site is funded by affiliate commissions, which never change a recommendation — our most common advice points people to the cheapest option or to keeping the pan they already own.
