5 Reasons Why Cast Iron Is The Greenest Choice For Cooking

Dependable, that’s what cast iron is. It will last for centuries if properly cared for, and it has a natural non-stick surface that’s eco-friendly. 

When I was a bride, my Granny gave me two of her cast iron skillets. A tiny, 6 inch one for making cornbread for two; and a 12 inch skillet for everything else. She told me all I’d ever need to be a good cook was those two skillets, a sauce pan, a stock pot and a casserole dish. And in a pinch, she said, I didn’t really even need the casserole.

Cast iron has been around for hundreds of years. Before fancy teflon cookware was even a notion, cast iron was the standard for good cooks everywhere. Dependable, that’s what cast iron is. It will last for centuries if properly cared for, and it has a natural non-stick surface that’s eco-friendly. You can bake a pan of cornbread, scramble some eggs, make your favorite vegetarian black bean chili or sear a perfect steak. Cast iron cookware is the definition of all-purpose.

If you don’t already have a cast iron skillet, here are a few reasons to go to your nearest resale shop or garage sale and begin looking for one. You won’t regret it.

Top 5 Reasons Why Cast Iron Cookware Is So Green…

Cast iron is naturally non-stick.
 Properly seasoned (see below) nothing will stick to it. Cast iron eliminates the need for the costly, toxic chemicals used to create the non-stick surfaces in modern cookware.

Eco-easy clean up. All cast iron cookware requires for clean up is hot water and a stiff brush, so you avoid any harmful chemicals in detergent or solvents.

Cast iron can take the heat.
 It can withstand much hotter temperatures and will distribute the heat more evenly than traditional cookware. And since it holds heat well, you can use less energy to cook. Plus it’s perfect for outdoor cooking. Just remember that cast iron gets hot. so use an oven mitt when handling a hot pan.

It’s a great upcycling opportunity.
 Don’t ever worry about buying a cast iron skillet or other cast iron cooking vessel—like a dutch oven—from a resale shop or garage sale. Even if it looks rusty and dirty, it can be cleaned and re-seasoned and continue on cooking, forever.

It’s good for you. Cast iron cookware leaches small amounts of iron into food, so you get a little extra iron each time you use it. Almost anyone, especially women in their child bearing years, will benefit from this.

How To Properly Season Cast Iron Cookware

First, wash your cast iron cookware. This is the only time you will need soap to clean it, but you want to be sure you remove any dust or dirt. If you have a brand new cast iron piece, you will need to do this to remove the wax coating that is on it to keep it from rusting until it’s seasoned.

Coat your piece in some type of oil.
 Cast iron has a porous surface. The seasoning process will fill and smooth the surface to make it non-stick. Some type of oil is used to facilitate this process. I use Crisco vegetable shortening. Traditionalists would use lard. You can use plain old cooking oil, too, but you will get better results with Crisco. You want to coat the entire cooking surface with the shortening. Don’t glob it on, but every nook and cranny should have a nice, medium layer of shortening. Use about as much as you would use to coat a cake pan for baking.

Bake it in the oven.
 Next, you just pre-heat your oven to 350 degrees and put your cast iron pan in for an hour or so. After heating, turn off the oven and let it cool completely while still in the oven. Then it’s ready to go!

Heating the cookware creates the oxidation that prevents rust and makes the surface non-stick. Some cast iron users advocate heating the pan slightly before applying the Crisco to ensure that the pan is completely dry and to open the pores of the pan before seasoning. Not a bad idea, but remember cast iron gets HOT. Use oven mitts.

Newly seasoned cast iron will take on a dark brown coating. After long use, it will become glossy black. The non-stick properties of the pan will increase with time and use, so use your cast iron often. Remember, seasoning is a process. Even though cast iron can be used immediately after the first seasoning, your cookware will get better and better over time.

How do I re-season a used cast iron piece? If you buy a cast iron piece second hand, the process is still basically the same to re-season it, with one exception. First wash it in hot soapy water, as above. Then I put it in my oven on the highest setting (or on the self-cleaning setting if you have one) and let it bake for a few hours without any oil or shortening. This will remove any rust and the old seasoning. Let it cool, then follow the steps above to re-season.

Caring For Your Cast Iron Cookware

After each use, clean your piece with very hot water and scrub with a stiff brush to remove any particles left behind. Don’t use soap, it will remove the seasoning. After you scrub the pan, give it a light coating with some Crisco or vegetable oil and store it in the oven. Why? Because the oven will have less moisture, this will help keep your cast iron from ever rusting. Plus, each time you use your oven is an opportunity to further season your pan. Even if you take your cast iron pan out while using your oven, give it a light coating of shortening before putting it back in the warm oven. Especially if it’s a new piece, this will help develop the seasoning further.

I have treasured those skillets Granny gave me, and I’ve added to my collection over the years. A dutch oven in 1989 and a griddle just last year. At a garage sale in Los Angeles about 15 years ago, I bought a giant, deep skillet that turned out to be called a Texas skillet. (An omen, I guess since I live in Texas now. ) I love my cast iron cookware. I’m guessing you will, too.

    I used to swear by cast iron. However, it turns out that extra iron is bad for almost everybody (a very few, especially women of child-bearing age need a small amout). Iron accumlates can causes many problems over time. I find that plain glass cookware, without teflon, is the best. Glass is what chemists use in the lab. Except for hydroflouric acid nothing touches it or causes it to “leak”. You have to cook using VERY low heat — which is also a good practice to prevent toxins from being created by the cooking process. Likewise, glass dishes are best. Ceramic is second best. You can get cast iron cookware coated in ceramic.

    I disagree wholeheartedly with this article. As a man, we have to be careful not to get too much iron, since we do not have a way to release it naturally as women do. Do you know how much iron gets into the food with the particular iron cookware you mention? This could be a recipe for disaster if the amounts known to leach are not available.

  • Greg says:

    I agree with the article, nothing like a 12″ skillet for cornbread for a family sit-down breakfast. I also have and use a chicken fryer and casserole which share the same size lid as a #8 skillet. These pans are great for deep-frying fish and other foods.
    Properly seasoned and maintained cookware shouldn’t present a problem with leaching, but tomato based products could be a caveat due to the acid.

  • I agree but with two important conditions.
    First, a GREAT MANY people have too much iron already and it is increasing their risks of many diseaes. Unless you know that your ferritin level is below 100, I would not begin cooking in cast iron. If it is below and you do begin to use cast iron, check your ferritin again in a year and see if it is getting too high (above 125 – 150)
    Second, I have read reports of varuious toxic contaminants in these when they are made in China, Taiwan etc. Mine are all made in the U.S.A. or Italy so find the good ones even if you need to shop in second hand stores and at swap meets to find the ones which made here (look on the bottom).

    Bob, you are paranoid. I have been cooking with a cast iron cookware for over 20 years. The coating of oil prevents the transfer of unhealthy amounts of iron. Also, it is a good idea to rub salt into the pan BEFORE coating with oil and after heating the pan. Heat, salt, coat. This fills the pores in the iron and accelerates the process to ‘non stick’ status. And I’d use clarified butter instead of Crisco.
