Caring for and Seasoning Cast Iron Cookware

Cast iron cookware is some of the most iconic kitchen equipment on a small homestead. Here’s what you need to know about seasoning cast iron pans, cooking with them, and cleaning them properly.

The durability, flexibility, and usefulness of a cast iron skillet or Dutch oven cannot be understated. That’s probably why most pioneer stories you come across involve cooking with these durable pans. But with the modern cookware we have available to us today, many are intimidated by cooking with and caring for such a piece of antiquity.

I was fairly reticent myself, until my husband surprised me with a cast iron skillet and I dove head first. Now I cook with cast-iron every single day. I have a collection that includes a couple of skillets, two sizes of Dutch ovens, and a griddle pan that makes homemade tortillas a breeze.

Cast iron cookware basics

Cooking with cast-iron is not hard to do or get used to, but it is slightly different than stainless steel. It is definitely much heavier which means it takes a bit longer to heat up. But it holds heat really well so you don’t have to keep it over such a high heat.

Cast-iron pans are durable and can be used on a fancy new stove top or the top of a wood stove or even over an open fire. It also works great in an oven, baking amazing breads, muffins, and more. Well-seasoned cast iron can be utilized for stick-free cooking and, as such, is a great alternative to modern, toxic teflon pans. Seasoning cast iron pans is an effort that’s well worth it, to avoid those toxins.

Caring for cast iron pans

While cast iron can easily replace Teflon or stainless steel cookware, it does take some special care, from seasoning cast iron pans properly, to cleaning and storing it.

Seasoning cast iron pans for a non-stick finish

The nonstick aspect of cast iron pans comes with proper seasoning. Seasoning cast iron does not involve salt, pepper, or herbs. Rather it is the process of baking fat into the surface of the pan at a moderate heat. This hardens the fat into the nooks and crannies of the cast-iron surface which, when done properly, truly creates a stick-free pan.

There is great debate over which type of fat or oil to use for seasoning.

Some say flax oil is the only one that works, others say old-fashioned lard is what great grandma used so it ought to be the go-to choice. But really, any fat will work, though I prefer something that can handle high heat without going rancid such as lard, tallow, or coconut oil. A well seasoned piece of cast iron cookware is great for stove top cooking, stewing, and even baking desserts like this skillet apple pie.

How to season cast iron cookware

Whether you are starting with an old pan from a thrift store or a brand new name-brand skillet, you are going to want to scrub it well with soap and water. I know new pans will say they are pre-seasoned but that is generally done with industrial oils like soy. The pans could have chemical or manufacturing residue. You’ll want to wash this off before seasoning cast iron for use in your kitchen.

Once the pan is clean and dry, it will look dull and light-colored. Now you can carefully spread the fat all over the surface of the pan – from the cook surface to the sides and bottom. In addition to creating a non-stick surface, seasoning cast iron on all its surfaces prevents it from rusting.

You want a thin layer so wipe away any excess fat.

Now place that into a 250 degree oven for a few hours and you will have your first layer of seasoning. This should be sufficient to get you started but further seasoning can be done for a tough non-stick layer. I actually find the best way to ensure a non-stick surface is to fry foods in my cast-iron skillets. It doesn’t have to be deep-fried – a simple 1/8 of an inch of fat for cooking things like falafel, salmon burgers, or other favorite shallow-fried foods really helps to ensure that non-stick layer.

Cleaning seasoned cast iron pans

This is the part that usually trips people up. Unlike most pans, you don’t want to utilize soap in cleaning cast-iron. The reason for this is simple: You’ve put some effort into creating a non-stick seasoning using fat. Fat emulsifies and is washed away when you wash with soap . Therefore, you will lose at least some of your cast iron seasoning every time you wash with soap.

(I have read many times that the whole “no soap rule” is a myth when it comes to cast-iron. But, after cooking with it for nearly ten years now, I’ve learned the hard way that if you want a non-stick surface, you really need to avoid using soap.)

Scrubbing seasoned cast iron pans

Assuming your non-stick surface is not perfectly non-stick – and there are always times when mine aren’t – you’re going to need to scrub some food stuffs from that pan. The best way I have found is to use something that is only very lightly abrasive to clean the inside of the pan. A stainless steel scrubber or coarse salt and a damp cloth are my favorite means of removing any stuck-on food pieces. Once loosened, simply wipe the pan clean with a dry cloth. I find using a few dedicated cloths for my cast-iron helps since they get stained and greasy.

If no food has stuck to the pan in the cooking process, simply wipe it clean. (And yes, seasoning cast iron pans properly really can leave them this non-stick!) This actually leaves a light layer of oil, seasoning cast iron further. Once you have scrubbed, if necessary, and wiped your pan clean, put it on a low burner and heat it up. This will kill any bacteria and you can put a thin layer of fat on it while it heats. This further builds your layer of seasoning.

Storing cast iron cookware

You never, ever want to put your cast iron cookware away when it’s damp, hence the heating the pan step as stated above. (Put away damp, they’ll rust and you’ll be back at square one with seasoning cast iron pans.) Furthermore, I find that stacking cast-iron pans can lead to unpleasant moisture or rust or dust collecting in pans.

You can store your pans in your oven, in a cabinet, or on very sturdy hooks. Make sure that if you are hanging your pans, they are braced with studs very, very sturdily. To this day I avoid hanging them above where people may be standing or walking – these pans are just too heavy duty to take a chance.
