Cooking with Cast Iron: Healthy for You and the Earth.
In a world full of nonstick pans that wear out quickly and end up in landfills, cast iron is making a comeback. By now, we all know nonstick can be great to cook with, until it gets one little scratch and then all that nonstick material is getting released and cooked right in with your food! Not good. More families are rediscovering this timeless cookware—and for good reason. Cast iron isn’t just durable, it’s also a healthier option for cooking and a more sustainable choice for the planet.
Health Benefits of Cooking with Cast Iron
1. Naturally Non-Toxic
Unlike some nonstick pans that can release harmful chemicals when overheated, cast iron is made of—you guessed it—iron. That means no hidden coatings or questionable materials.
2. Adds a Boost of Iron to Your Food
Cooking with cast iron can actually increase the iron content in your meals, especially when making acidic dishes like tomato sauce. This is especially helpful for kids, women, and anyone who may be prone to low iron levels.
I got my levels checked with my third pregnancy and my midwife was shocked at my iron levels. She said, Wow you must eat really healthy. I was like well not really but I cook almost exclusively with cast iron!
3. Retains and Distributes Heat Evenly
Cast iron holds heat like no other pan. This makes cooking more efficient (less energy wasted) and helps food cook evenly, which means healthier meals with less burning or overcooking.
I learned a lot about making sure food doesn't stick to your cast iron. Read my original Facebook post about eggs here. While you are there, give me a follow! My main takeaway has been to make sure the pan is hot but not too hot (you'll know, the oil or butter you are using will start burning) and to rub oil in after each use.
Earth-Friendly Benefits of Cast Iron
1. Built to Last a Lifetime
While many pans wear out after just a few years, cast iron can last for generations with proper care. Fewer replacements mean less manufacturing waste and less clutter in landfills.
2. Fully Recyclable
At the end of its life (which is usually decades away), cast iron can be recycled instead of tossed. It’s a true cradle-to-cradle product. I've seen reels on Facebook of a guy who rescues them from landfills and makes them new again. I've also heard of people still using their grandmother's cast iron pans. That is almost unheard of these days!
3. Reduces the Need for Disposable Cookware
Families who rely on sturdy cast iron tend to need fewer cheap pans, which helps reduce overall consumption and waste. I haven't purchased any new pans since we got different sized cast iron. I do have a stainless steel set of pots and pans as well. My husband prefers these when he's making eggs and this covers all my pot needs. If you aren't using cast iron, stainless steel is your next best bet for health and the environment.
I have this set of three pans from Lodge, 8, 10.25 and 12 inches to cover many of our cooking needs.
I also have this Lodge Dutch Oven which we use on the stove, in the oven and even on the campfire and our Big Green Egg.
There's also this 5 piece set which includes the Dutch Oven and 3 different sized pans if you are looking to start your collection at a good price! I love Lodge because it's been made in the USA since 1896 and they come pre-seasoned. I have had mine for about 10 years and have never had a problem.
The Bottom Line
Cast iron is more than just a kitchen tool—it’s an investment in your family’s health and the earth’s future. By choosing cookware that’s naturally non-toxic, long-lasting, and eco-friendly, you’re taking a small step toward a healthier home and a more sustainable lifestyle.
