Meal Planning, Prep, and Cooking
Gas range, electric stove, wood stove, campfire, charcoal grill, or a pile of coals in the yard. Cast iron does not care what produces the heat. That indifference is exactly why it belongs in every self-reliant kitchen.
Why this matters
Most cookware is designed for one heat source. Nonstick pans work on a regulated stovetop. Glass bakeware works in an oven. Neither survives a campfire. Cast iron works on all of them, and it works on heat sources that have not been invented yet, because the physics are simple: iron conducts heat, holds it, and distributes it evenly regardless of where that heat comes from.
This is why cast iron has been the default cookware for most of human history, and why it matters for self-reliance. When your cooking method changes, whether from a power outage, a move to wood heat, or a weekend at a campsite, cast iron transitions with you. The skillet that sears a steak on your gas range Tuesday night cooks cornbread over a campfire on Saturday. The Dutch oven that slow-cooks a roast in your kitchen oven bakes bread in a bed of coals.
Cast iron also contributes small amounts of dietary iron to food cooked in it, which is a meaningful benefit for households where iron intake is a concern. And a properly maintained piece of cast iron improves with age. The pan your grandchildren cook with will be better seasoned than the one you started with.Cooperative Extension: Cast irons can go a long way with all the additional benefits including iron contribution to diet">[1]
Where to start
A 10- or 12-inch cast iron skillet handles searing, frying, sauteing, baking, and roasting. It is the single most versatile piece of cookware you can own. If you buy one piece of cast iron, make it a skillet.
A 10-inch skillet suits one to two people. A 12-inch skillet handles family meals. Most new cast iron skillets come pre-seasoned from the manufacturer and are ready to cook with immediately, though building additional seasoning layers improves performance.
A cast iron Dutch oven with a tight-fitting lid handles stews, soups, roasts, baking bread, and anything that simmers or braises. A 5- to 7-quart size serves most families.
For outdoor and wood-stove use, choose a camp Dutch oven with legs and a flanged lid designed to hold coals on top. For stovetop and oven use, a flat-bottomed, lidded Dutch oven (with or without enamel coating) is the standard. Note that enameled cast iron should not be used directly over an open flame, as the enamel will crack.
Beyond these two, a cast iron griddle is useful for pancakes, tortillas, and flatbreads, and a cast iron grill pan provides grill marks when you are cooking indoors. But the skillet and Dutch oven together cover the vast majority of cooking tasks across any heat source.
The foundation
Seasoning is not a spice. It is a thin layer of polymerized oil bonded to the iron surface. When oil is heated past its smoke point on cast iron, it undergoes a chemical change that converts it from a liquid fat into a hard, plastic-like coating. This coating protects the iron from rust, creates a naturally nonstick cooking surface, and gets better with every use.[2]
Most new cast iron comes pre-seasoned, but you can add layers for better performance. Wash the pan with soap and water, dry it completely, then apply a very thin coat of oil (flaxseed, vegetable, or canola) over all surfaces, inside and out. Wipe off the excess until the surface looks nearly dry. Too much oil creates a sticky finish. Place the pan upside down in an oven at 450 degrees Fahrenheit for one hour, with a sheet of foil on the rack below to catch drips. Let the pan cool in the oven. Repeat two to three times for a solid base layer.
The best way to build seasoning is to cook with your cast iron regularly. Frying, searing, and cooking with oil or fat all add thin layers of polymerized oil to the surface. Foods that build seasoning well include anything fried in oil, bacon, cornbread, and roasted vegetables. Foods that are harder on seasoning, at least until the seasoning is well established, include acidic foods (tomato sauce, citrus-based dishes, wine reductions) which can strip thin seasoning layers.
Clean the pan while it is still warm (not hot). Rinse under hot water and scrub with a stiff brush, a chainmail scrubber, or a nonabrasive pad to remove stuck food. Dry the pan immediately and thoroughly. Apply a very thin layer of oil to the cooking surface with a paper towel. That is the full routine. Modern dish soap is safe for well-seasoned cast iron; the old prohibition dates to an era when soap contained lye. What damages seasoning is soaking in water, air-drying (which causes rust), and storing wet.[1]
Using cast iron well
Cast iron heats slowly and unevenly at first. Place the skillet over medium-low heat for five minutes before turning it up. This allows the iron to absorb and distribute heat evenly across the cooking surface. Putting a cold skillet over high heat creates hot spots in the center and cold edges, which causes food to cook unevenly and stick.
Cast iron retains heat exceptionally well. Once it is hot, it stays hot, even if you reduce the flame. Medium heat on a cast iron skillet produces results equivalent to medium-high on thinner cookware. Start lower than you would with stainless steel or aluminum. You can always add heat. Cooling an overheated cast iron pan takes a long time.
Even a well-seasoned pan benefits from a thin layer of cooking oil or butter before food goes in. Heat the oil until it shimmers (but does not smoke), then add the food. This layer of hot fat is what creates the release that keeps food from sticking. Cold oil or cold food in a hot pan is the most common cause of sticking.
When you sear meat or cook pancakes, the food will stick at first and then release on its own when it is ready to flip. If you try to flip too early, you tear the surface. Wait until the food lifts cleanly with gentle pressure from a spatula. This patience is the difference between a beautiful sear and a torn, stuck mess.
When things go wrong
Rust means the seasoning was breached and the bare iron was exposed to moisture. It is not the end of the pan. Scrub the rust away with steel wool or a stiff brush until you see bare gray iron. Wash with soap and water, dry completely, and re-season the pan using the oven method described above. A rusted pan found at a yard sale is often one afternoon's work away from being a perfectly good skillet.
A sticky surface means too much oil was applied during seasoning and it did not fully polymerize. Place the pan upside down in a 450-degree oven for an hour to finish the polymerization. If the stickiness persists, strip the seasoning with steel wool and start the seasoning process fresh. The fix is always the same: thin layers of oil, high heat, full polymerization.
Sticking is almost always a heat or fat problem, not a pan problem. Either the pan was not preheated long enough, the fat was not hot enough when the food went in, or the food was flipped too early. It can also mean the seasoning is thin and needs more cooking sessions to build up. Cook a few rounds of bacon or cornbread, and the problem usually resolves itself.
Beyond the kitchen
The same cast iron that works on your kitchen stove works on every alternative heat source. This is the reason it appears on nearly every preparedness equipment list and why it has been the default cookware for outdoor cooking for centuries.
Place the skillet or Dutch oven directly on the cooking surface of the wood stove. Heat control comes from placement: the center of the stovetop is hottest, the edges are cooler. Move the pan to adjust temperature. A wood stove doubles as a cooking surface during winter, letting you heat the house and prepare meals with the same fuel. See the Wood Stove Cooking guide for detailed technique.
For skillet cooking, set the skillet on a grate over the fire or balance it on a stable arrangement of rocks at the edge of the fire pit, where heat is more controllable than directly over the flames. For Dutch oven cooking, the best results come from cooking in a bed of coals rather than over open flame. Shovel coals underneath and on top of the flanged lid for even, oven-like heat.
A practical guideline for Dutch oven cooking with charcoal briquettes: double the diameter of the oven in total coals for approximately 350 degrees Fahrenheit. A 12-inch oven needs about 24 coals total. Place roughly two-thirds on the lid and one-third underneath for baking. For simmering and stewing, reverse the ratio: more coals underneath, fewer on top. Rotate the oven and lid a quarter turn every 15 minutes to prevent hot spots.
