Cast Iron Cooking: Why Every Kitchen Needs a Cast Iron Skillet

In a world of non-stick coatings, ceramic surfaces, and space-age materials, the humble cast iron skillet endures. It has been a kitchen essential for hundreds of years, and for good reason — no other piece of cookware offers the combination of versatility, durability, heat retention, and value that cast iron provides.

Cast iron excels at heat retention. Once it gets hot, it stays hot, even when you add cold food to the pan. This is crucial for achieving a proper sear on steaks, chops, and fish. Stainless steel and aluminum pans lose temperature rapidly when food is added, which can lead to steaming instead of searing. Cast iron powers through, maintaining the high temperatures needed for that perfect brown crust.

The versatility of cast iron is unmatched. You can use it on the stovetop, in the oven, on a grill, over a campfire, or even on an induction cooktop. You can sear a steak, bake cornbread, fry chicken, roast vegetables, make a frittata, bake a pizza, or cook a cobbler — all in the same pan. No other piece of cookware can do all of that.

One of the most common misconceptions about cast iron is that it is difficult to maintain. In reality, caring for cast iron is simple. After cooking, rinse the pan with hot water and use a brush or scraper to remove any stuck-on food. Dry it immediately and apply a thin coat of oil. That is it. Contrary to popular belief, a little soap is fine — modern dish soap will not strip your seasoning.

Seasoning is the natural non-stick coating that develops on cast iron over time. It is created when oil is heated past its smoke point, causing it to polymerize — essentially turning into a hard, plastic-like coating that bonds to the iron surface. Each time you cook with oil in your cast iron, you are adding another thin layer of seasoning.

To season a new or restored cast iron pan, preheat your oven to 450 degrees. Apply a very thin layer of a high smoke-point oil — flaxseed, grapeseed, or vegetable oil work well — to the entire surface of the pan, inside and out. Then wipe off as much oil as you can with a paper towel. Place the pan upside down in the oven for one hour, then let it cool in the oven. Repeat this process 3-4 times for a solid base seasoning.

The best foods to cook in cast iron when building seasoning are fatty, oily foods — bacon, sausages, fried chicken, and cornbread are all excellent choices. Avoid highly acidic foods like tomato sauce or wine-based dishes until your seasoning is well established, as acid can break down new seasoning. Once your pan has a solid seasoning, it can handle anything.

Cast iron actually improves with age. A well-used cast iron pan that has been properly maintained for decades will have a seasoning so smooth and durable that it rivals any non-stick coating — without any of the health or environmental concerns associated with synthetic non-stick surfaces. This is why vintage cast iron is so prized by collectors and cooks alike.

When it comes to searing meat, cast iron is king. Preheat your pan over medium-high heat for a full five minutes before adding oil and your protein. The pan should be smoking hot. Pat your meat completely dry — moisture is the enemy of a good sear — season generously with salt and pepper, and lay it in the pan away from you. Do not touch it for at least 3-4 minutes. When it releases easily from the pan, it is ready to flip.

Cast iron cornbread is a Southern tradition for good reason. The heavy pan retains heat so well that it creates a crispy, golden crust on the bottom and sides of the cornbread while keeping the interior tender and moist. Preheat the pan in the oven with a tablespoon of butter or bacon fat, pour in your batter, and bake. The sizzle when the batter hits the hot pan is the sound of cornbread perfection.

A quality cast iron skillet costs between $20 and $40 and will literally last forever if you take care of it. Compare that to a $200 non-stick pan that needs to be replaced every few years. Cast iron is the best value in cookware, period. Lodge, Victoria, and Camp Chef all make excellent, affordable cast iron that will serve you well for a lifetime.

If you only own one cast iron piece, make it a 12-inch skillet. It is large enough to sear four chicken breasts or a full steak, deep enough for pan sauces and shallow braises, and versatile enough to handle baking. Add a cast iron Dutch oven down the road, and you will have a cookware set that can handle virtually any cooking task.
