There's a cast iron skillet in most Kentucky kitchens. If yours is hiding in a cabinet with a rust spot and a mystery crust, this is your guide to bringing it back — and keeping it there on the stovetop where it belongs.
Cast iron cookware has been the backbone of Southern cooking for generations — and for good reason. It holds heat evenly, goes from stovetop to oven without a second thought, and with proper care, lasts longer than any nonstick pan you'll ever buy. The learning curve isn't steep. It's mostly about habit.
Seasoning isn't about flavor — it's a polymerized oil coating baked into the pores of the iron that creates a naturally nonstick surface and protects against rust. A well-seasoned pan is dark, slightly shiny, and smooth to the touch. Every time you cook with fat and heat, you add to that seasoning. The pan gets better with use.
To season a bare or restored skillet: rub a very thin layer of flaxseed oil, vegetable oil, or Crisco all over — including the bottom and handle. Place it upside down in a 450°F oven for one hour. Let it cool in the oven. Repeat 3–4 times and you have a solid foundation.
The cast iron rules around cleaning have been overstated. Here's the actual truth: soap in small amounts is fine on a well-seasoned pan. What you want to avoid is soaking it in water or leaving it wet — that causes rust. Wash it with hot water and a stiff brush, dry it immediately on the stove over medium heat for 2–3 minutes, and rub in a paper towel's worth of oil while it's still warm. That's your entire maintenance routine.
Rust on cast iron is not the end. Scour the rust off with steel wool or a chain-mail scrubber under running water — you can go hard, you won't hurt it. Dry completely on the stove over high heat until all moisture has evaporated. Then season from scratch as above. A pan that looks hopeless after a decade in a barn can come back to full function in an afternoon.
Some things cast iron does better than any other pan:
A few things cast iron doesn't love: highly acidic ingredients cooked for a long time (tomato sauce simmered for an hour can strip seasoning and pick up a metallic taste), dishwashers (the harsh detergent and heat cycle strip seasoning fast), and air drying after washing. Other than that — use it for almost anything.
