Cast Iron Care 101: Cleaning, Seasoning & Cooking Tips

Why Cast Iron Is Worth the Extra Care

Cast iron cookware can genuinely last generations — plenty of people cook on skillets inherited from a grandparent. It develops a natural, food-safe non-stick coating (called "seasoning") over time, holds heat incredibly well, and can go from stovetop to oven to campfire. The tradeoff is that it needs a bit more care than non-stick or stainless steel. Here's exactly what that care looks like.

Cleaning Cast Iron the Right Way

• Skip the soap (mostly): A small amount of mild soap is fine occasionally, but heavy scrubbing with soap regularly can strip seasoning over time.
• Clean while it's still warm: Food releases more easily, and it's much less effort than waiting until it's cold.
• Use a stiff brush or chainmail scrubber: For stuck-on food, a stiff brush or salt scrub works better than metal scouring pads, which can damage seasoning.
• Dry immediately and completely: Cast iron rusts if left wet — towel dry, then place on low heat for a minute to fully evaporate any moisture.

Seasoning: The Step Most People Skip

After cleaning and drying, rub a very thin layer of oil (vegetable, canola, or flaxseed oil all work well) over the entire pan — inside and out. Wipe off any excess with a paper towel until it looks almost dry. This thin oil layer polymerizes with heat and builds up the pan's protective, non-stick seasoning layer over time.

If your pan ever gets a spot of rust or the seasoning looks patchy, don't panic — a stovetop or oven re-seasoning session (a few thin oil coats baked on at 450–500°F) will bring it right back.

Cooking Tips for Better Results

• Preheat cast iron for a few minutes before adding food — it holds heat unevenly until it's fully warmed through.
• Cast iron is ideal for searing steaks, roasting vegetables, and baking cornbread — anything that benefits from strong, even heat retention.
• Avoid cooking very acidic foods (tomato sauce, wine reductions) for long periods — acid can slowly break down seasoning over repeated use.
• A little extra oil when cooking eggs or delicate fish helps prevent sticking, especially on a newer or lightly-seasoned pan.

With just a few minutes of care after each use, a good cast iron skillet will genuinely outlast almost every other pan in your kitchen — and it only gets better with age.
