Meal Planning, Prep, and Cooking
The pan that works on anything that burns.
Gas range, glass-top, induction, oven, grill, wood stove, or a bed of coals in the yard. Cast iron cooks on all of them. This guide covers seasoning, heat control, every common heat source, baking, and the fixes for the problems everyone runs into.

FROM THE FIELD
Almost every "ruined" cast iron pan in the accounts turns out to be a seasoning or heat mistake, not a dead pan. The pattern repeats across cooking forums and first-year write-ups: too much oil baked at too low a temperature, or food added before the pan was hot, and the cook blames the iron. This page is built around those two variables, because getting them right fixes most of what goes wrong.
Why this matters
Cookware that outlasts everything else in the kitchen.
Most cookware is built for one heat source. Nonstick pans want a regulated stovetop. Glass bakeware wants an oven. Cast iron works on a gas burner, an electric coil, a glass-top range, an induction cooktop, in the oven, on a grill, and over campfire coals.[3]
That range is 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, the same pan comes with you. The skillet that sears a steak on the range Tuesday night bakes cornbread on a charcoal grill Saturday.
It also lasts. A pan that is cleaned, dried, and oiled after use keeps improving for decades. One honest note: cast iron does add a little iron to food, but UMaine Extension calls the amount negligible next to what the body needs from food, so it is not a reason to buy one.[1]
Where to start
Two pieces that cover nearly everything.
The skillet
A 10- or 12-inch cast iron skillet handles searing, frying, sauteing, baking, and roasting. If you buy one piece of cast iron, make it a skillet.
A 10-inch skillet suits one or two people. A 12-inch handles family meals. Most new pans come pre-seasoned and ready to cook.[2]
From the field · First-time buyers describe the same regret: a 12-inch skillet that was too heavy to tip one-handed, so it stayed in the cupboard. Start with the size you can lift when it is full.
The Dutch oven
A lidded Dutch oven handles stews, soups, roasts, beans, and bread. A 5- to 7-quart size serves most families.
For coals and campfires, choose a camp Dutch oven with legs and a flanged lid that holds coals on top. For the stove and oven, a flat-bottomed pot is the standard. Enameled pots belong indoors: Lodge does not recommend its enameled pieces for campfire use because the heat can affect the finish.[3]
A griddle is useful for pancakes, tortillas, and flatbreads, and a grill pan gives you grill marks indoors. Our cast iron cookware handbook covers sizes, weights, and bare versus enameled iron if you are choosing a first piece. Browsing old pans at flea markets instead? The cast iron collecting guide explains maker's marks and which secondhand pieces belong in the kitchen.
The foundation
Seasoning: what it is and how to build it.
Seasoning is not a spice. It is a thin coating of oil baked onto the iron until it hardens. That coating protects the iron from rust and gives the pan its natural nonstick surface.[2] It gets better the more you cook.
Oven seasoning (new, dull, or stripped pans)
Wash and dry the pan completely. Rub a very thin coat of oil over every surface, inside and out, then wipe it back until the pan looks almost dry. Bake it upside down at 450 to 500°F for one hour, with foil on the rack below to catch drips, and let it cool in the oven.[5] UMaine Extension suggests repeating this three to five times for a thick coat.[1]
-
Wash and dry
Remove every trace of moisture.
-
Oil all surfaces
Coat the pan inside and out.
-
Wipe almost dry
A heavy coat turns sticky.
-
Bake upside down
450–500°F for one hour.
-
Cool and repeat
Cool in the oven; repeat as needed.
For oil, both Lodge and UMaine recommend a neutral oil with a high smoke point, such as vegetable or canola. Lodge advises against lard, tallow, and ghee for seasoning because they can go rancid. Cooking with them is fine.[6]
Building seasoning through cooking
Regular cooking with oil or fat adds to the coating. Frying, searing, bacon, cornbread, and roasted vegetables are all good early meals for a new pan.
Tomato sauce, wine, and citrus
Acidic food is fine in a well-seasoned pan for a short time. Lodge's guidance is to keep acidic ingredients in direct contact with bare cast iron for no more than about 45 minutes, and to reach for enameled cast iron for long simmers.[7] Wash, dry, and oil the pan afterward.
After every use
Clean the pan soon after cooking, while it is still warm. Scrub with hot water and a stiff brush or soft sponge. For stuck-on bits, America's Test Kitchen suggests scrubbing with a thin layer of coarse salt before rinsing.[13]
Soap is fine in moderation. Lodge's own restore steps include warm, soapy water,[5] and UMaine Extension advises a small amount followed by a full rinse.[1] Skip steel wool and scouring pads for everyday cleaning, since extension guides note they remove seasoning.[2] Save them for rust.
Then dry it right away, never in the dish rack, and wipe on a very thin film of oil before storing. Never soak cast iron and never put it in the dishwasher.[2]
Using cast iron well
Heat management is the whole skill.
Preheat slowly
Start the pan on medium-low for a few minutes before turning it up. Lodge recommends a slow preheat to avoid thermal shock, a sudden temperature change that can damage the iron.[3] A cold pan on high heat gives you a scorching center and cool edges.
Use less heat than you think
Iron holds heat and keeps absorbing it. Lodge notes you usually need a lower setting than with stainless steel or aluminum,[4] and that medium-high suits most cooking.[3] You can always add heat. Cooling an overheated pan takes a long time.
Test with water
Flick a few drops of water into the pan. If they dance across the surface, the pan is ready. If they vanish instantly, or the oil smokes, it is too hot: pull it off the burner for a minute and lower the setting.[3]
Let food release on its own
Seared meat and pancakes grip the pan at first, then let go when they are ready to turn. Flip too early and you tear the crust. Wait until the food lifts cleanly with a gentle push of the spatula.
Indoors
How does cast iron work on each kind of stove?
One rule covers all of them: match the pan to the burner. Lodge warns that a pan much larger than the burner develops hot spots, which can warp or crack it.[3]
Gas
Heats fast and responds quickly when you turn the knob, and the flame shows you what is happening. It can heat unevenly, so pick the burner closest in size to the pan.[3]
Electric
Gives steady, even heat with fewer hot spots, but reacts slowly. Preheat gradually and make changes in small steps, then wait for the pan to catch up.[3]
Glass and ceramic tops
Safe to use, according to Lodge. Lift the pan to move it rather than sliding it across the glass, which can scratch the surface.[3]
Induction
Works well because iron is magnetic. The pan needs a flat bottom for full contact, and induction is efficient enough that Lodge suggests a lower setting than you would use elsewhere.[3] Lift, do not slide.
From the field · Glass-top owners who report scratches almost always trace them to sliding a pan or a ceramic dish, and the cast iron that causes trouble is a warped piece that rocks. Flat pans, lifted, go years without a mark.
In the oven, cast iron goes from stovetop to rack without changing pans, which is what makes skillet frittatas, roast chicken, and cornbread so easy. America's Test Kitchen notes that preheating the pan in the oven helps it hold steady heat once food goes in.[13] Handles get as hot as the pan, so keep a dry mitt or handle cover within reach. For the basics of stove and oven settings, see stovetop and oven fundamentals.
The most common complaint
Why does food stick to cast iron?
Lodge's answer: the pan is usually too hot, or there is not enough oil.[4] Thin seasoning plays a part on a new pan, and flipping too early tears what has not released yet.
| Cooking | What to do |
|---|---|
| Eggs | Use more oil than you think, coating the whole bottom. Eggs are among the stickiest foods. |
| Chicken thighs, bacon, fatty meat | Use less added oil. The food renders its own fat. |
| Anything in butter | Start with a thin layer of oil, then add the butter, so the butter does not stick or burn. |
| High-heat searing | Use a neutral oil with a high smoke point, such as canola or grapeseed. Olive oil suits lower heat. |
| Any food | Preheat the pan, then heat the oil until it shimmers. If it smokes, pull the pan off the heat for a minute or two. Oil that is not hot enough soaks into food instead of searing it. |

Baking
Can you bake in cast iron? Yes, and it browns beautifully.
Cast iron's heat makes crisp edges and deep browning. Lodge's baking advice comes down to three points.[4]
A good first meal for a new pan
America's Test Kitchen points beginners toward skillet cornbread, a frittata that moves from stovetop to broiler, and one-pan chicken dinners.[13] All three use plenty of fat and help build seasoning.
For bread, a lidded Dutch oven holds steam around the loaf the way a professional oven does. The sourdough baking and bread baking guides take it from there.
Beyond the kitchen
Grill, campfire, wood stove, and open coals.
This is where cast iron earns its place in a prepared household. During a power outage, a grill or a bed of charcoal becomes the stove.
Grills and charcoal stay outside, always
The CDC says never to use grills or other gasoline-, propane-, or charcoal-burning devices inside your home, garage, or carport, or near doors, windows, or vents, because they produce carbon monoxide.[10] The U.S. Fire Administration adds: keep the grill well away from siding and deck railings and out from under eaves and branches, keep a 3-foot safe zone around it for children and pets, and never walk away from a lit grill.[11]
On a gas grill
Preheat the grill to medium-high with the pan on the grates. Lodge says this can take 5 to 10 minutes, faster with the lid closed. Iron keeps building heat, so you may need to turn the burners down once it is hot. The middle and back of most grills run hottest.[3]
On a charcoal grill
Light the charcoal in a chimney starter until the coals gray over, about 10 minutes, then set the vents. Leave room around the pan for air to flow, and use a high smoke point oil so it does not burn. No lid? Lodge suggests using a second skillet as a lid to trap heat.[3] Once the coals are cold, the U.S. Fire Administration says to put them in a metal can with a lid.[11]
Over a campfire
Cook over coals, not flames. Lodge recommends cooking over coals rather than direct flame, using a chimney starter to manage them. A grate over the coals gives the pan a stable surface.[3] Build the fire at least 25 feet from tents, shrubs, and anything that can burn.[11] The campfire cooking guide covers fire building and heat zones.
On a wood stove
Set the pan directly on the stove top and control heat by position: the center runs hottest and the edges cooler. Move the pan instead of adjusting the fire. A wood stove that heats the house in winter can cook dinner too. The wood stove cooking guide covers the details.
How many coals does a camp Dutch oven need?
Charcoal briquettes make Dutch oven heat predictable. These counts come from Lodge's coal chart. Each cell shows the total, then how many go on the lid and how many underneath.[8]
| Temperature | 8-inch | 10-inch | 12-inch | 14-inch |
|---|---|---|---|---|
| 325°F | 15 (10 lid, 5 under) | 19 (13, 6) | 23 (16, 7) | 30 (20, 10) |
| 350°F | 16 (11, 5) | 21 (14, 7) | 25 (17, 8) | 32 (21, 11) |
| 375°F | 17 (11, 6) | 23 (16, 7) | 27 (18, 9) | 34 (22, 12) |
| 400°F | 18 (12, 6) | 25 (17, 8) | 29 (19, 10) | 36 (24, 12) |
| 425°F | 19 (13, 6) | 27 (18, 9) | 31 (21, 10) | 38 (25, 13) |
| 450°F | 20 (14, 6) | 29 (19, 10) | 33 (22, 11) | 40 (26, 14) |
Match the split to the job
The chart is for baking. Lodge says roasting uses an even split, and boiling, stewing, and frying put all the coals underneath, none on the lid.[8]Spread and turn
Space the coals evenly rather than bunching them, which burns food. Every 10 to 15 minutes, lift and turn the oven a quarter turn, then turn the lid a quarter turn the other way.[8]Adjust and refresh
University of Idaho Extension's 4-H manual adds about 20 to 25°F for each extra coal on top plus one underneath, and says to replace coals once they burn to less than half their size.[9] Lodge suggests about 25°F more above 3,000 feet.[8]Lodge notes that outdoor temperature and humidity change how many coals you need, so treat any count as a starting point and check the food. More recipes and technique are in the Dutch oven cooking guide.
From the field · Camp cooks describe the bottom scorching while the top stays pale far more often than the reverse. The usual causes are too many coals underneath, ash left to build up on the lid coals, and wind pulling heat off one side.
Use a thermometer outdoors
Coals and grills are harder to judge than a stove dial, so check meat with a food thermometer. The federal safe minimums: 145°F for beef, pork, and lamb steaks, roasts, and chops, with a 3-minute rest; 160°F for ground meat and sausage; 165°F for all poultry and for leftovers; 145°F for fish.[12] The food safety guide covers what to keep and what to toss when the power goes out.
When things go wrong
Cast iron is hard to ruin.
Rust
Usually from soaking, the dishwasher, air drying, or damp storage. Surface rust scrubs off with steel wool, then the pan gets washed, dried, and re-seasoned.[5] The full method, including how to judge a secondhand pan, is on the restoring cast iron page.
Sticky or gummy surface
Too much oil went on during seasoning. Lodge's fix is to bake the pan upside down for another hour at seasoning temperature. Next time, wipe the oil back harder.[5]
Dull, blotchy, or flaking spots
The seasoning is thin or wearing. Lodge's answer to a dull finish is another round of oven seasoning.[5] Then cook with fat for a few weeks.
Food sticks
Almost always heat or oil, as the sticking table shows. On a new pan, a few rounds of bacon or cornbread help.
