Cast Iron Pan: Complete Guide to Buying, Seasoning and Cooking

A well-seasoned cast iron pan is one of the most versatile and durable cooking tools you can own. It sears meat better than almost any other pan, goes from stovetop to oven seamlessly, and with proper care will last generations. Here's everything you need to know.

Why Cast Iron?

Cast iron retains heat exceptionally well — once hot it maintains temperature even when cold food is added, producing better searing than thin stainless or aluminium pans. It goes from hob to oven to campfire without damage. A well-seasoned surface develops genuine non-stick properties over time. And unlike non-stick pans, cast iron actually improves with age and use.

Choosing a Cast Iron Pan

Lodge is the most recommended brand for beginners — American made, pre-seasoned, and available at very accessible prices. A 10-inch or 12-inch skillet covers most cooking tasks. Heavier pans retain heat better but require more strength to handle. Pre-seasoned options save time but benefit from additional seasoning before first use. Vintage cast iron (found at thrift stores and markets) is often superior to new — the cooking surface smooths out with decades of use.

How to Season Cast Iron

Seasoning is the process of baking oil into the iron surface to create a non-stick layer and prevent rust. Wash the pan with soap and water (the only time soap is recommended), dry completely, apply a thin layer of flaxseed oil, vegetable oil, or Crisco to every surface including the handle and exterior. Place upside down in an oven at 450°F (230°C) for an hour. Let cool in the oven. Repeat 3-4 times for a strong initial seasoning. The pan darkens and develops a glossy patina with each seasoning cycle.

What to Cook in Cast Iron

Cast iron excels at: searing steaks and chops, cooking bacon, frying eggs (on a well-seasoned surface), making cornbread, cooking pizza, roasting vegetables, deep frying, and baking skillet cookies and brownies. Avoid cooking acidic foods like tomatoes, citrus, and wine sauces in new or poorly-seasoned cast iron — acid strips the seasoning. These are fine once the pan has years of seasoning built up.

Cast Iron Care

Clean while still warm using hot water and a stiff brush or chainmail scrubber — not soap regularly, not a dishwasher. Dry immediately and completely — cast iron rusts quickly. Apply a very thin coat of oil after drying and heat briefly on the hob to bond it. Store in a dry place. If rust appears, scrub with steel wool, re-wash, and re-season completely. Cast iron is almost impossible to permanently damage — it can always be restored.
