Is Cooking With a Cast-Iron Skillet Better for Your Health? ›

Yes, cooking in a cast iron skillet can add significant amounts of iron to your food and into your body. In addition to eating more iron-rich foods like meats, beans, and spinach, cooking in a cast iron pot is an easy way to boost your iron intake. Iron is an essential nutrient for all the cells in our body.

So, Is Cooking in Cast Iron Healthier than Cooking in Other Pans? In short: No. You'd have to be mouse-sized to see quantifiable health benefits from mineral intake exclusively with cast iron. Because mineral transfer happens at such a small scale, it's safe to say that cast iron is not any healthier than other pans.

When used every day, the care for your cast iron is pretty simple. After cooking, wipe out the pan with a paper towel. If needed, use hot water, a brush, nylon scraper, or chainmail-type scrubber, and scrub out the pan.

The least toxic cookware are non-stick pans and pots, like cast iron, stainless steel, ceramic, glass, and enamel-coated cast iron. These options don't have any Teflon coating on them, making them safe to use.

The acidity of tomatoes makes them challenging to cook in cast iron. Anyone who's ever eaten a tomato or cooked with tomatoes can verify that this fruit is quite acidic. As it happens, the tomato's acidity is precisely why doesn't work well with cast-iron cookware, especially for long cooking stretches.

Should I Oil My Cast Iron After Every Use? After each use, to get the most out of your cast-iron skillet, it is best practice to apply a thin layer of oil on the surface. Regularly oiling your cast iron skillet will provide a protective layer to the surface and help keep it from rusting.

Cast iron pans can leach a sizeable amount of iron into your food, exceeding dietary intake in some cases. Acidic foods will contribute to much more leaching while an old, heavily-seasoned pan will leach much less iron than a newer one.

What are you not supposed to do with cast iron? ›

Cast iron pans are poor conductors of heat: Without getting too nerdy here...a cast iron is good at retaining (keeping) heat, but it isn't as good as conducting (transmitting) heat. A cast iron pan will heat unevenly if you're using a burner that's significantly smaller than the pan itself.

All cooking oils and fats can be used for seasoning cast iron, but based on availability, affordability, effectiveness, and having a high smoke point, Lodge recommends vegetable oil, melted shortening, or canola oil, like our Seasoning Spray.

With a few simple tricks to choose the right oil and get your pan to that just-right temperature, you'll get eggs with crispy edges and runny yolks every time (if that's your jam). But don't worry, cast iron makes the perfect egg no matter how you like them done!

One big advantage of carbon steel over cast iron is that carbon steel pans heat up much more quickly. And because it's more conductive than cast iron, it heats more evenly, with fewer hot spots.

Teflon (and other similar chemicals):

Anything coated with Teflon (think non-stick pans) or similar chemicals should be avoided in the kitchen. Teflon is made of a specific type of Perfluorocarbon (PFC) that makes the surface of cookware resistant to sticking.

Stainless Steel Frying Pans

Best for: Almost any food that needs frying, browning, or searing. Because it's ovenproof, stainless is also a good choice for foods that you start on the stovetop and then move to the oven to finish, like thick pork chops.

Making them in a cast iron skillet is ideal, as it heats evenly, and provides enough surface area to not overcrowd the onions (meaning they caramelize vs. steam). The final product is worth the wait though, producing sweet, jammy and delicious onions you can use in just about any way you can imagine.

Can cast iron cause iron toxicity? Only people with hemochromatosis are at risk of iron toxicity from cast iron cookware. Even then, the risk is low, since a new, well-seasoned cast iron pan only leaches about five milligrams of iron per cup of food. Older pans will leach less cast iron.

It is sturdy and holds the heat for a longer time. There are plenty of benefits in cooking in a cast iron skillet, for instance, they are relatively and naturally non-stick and help in enhancing the flavors of your food. This amazing kitchen tool can also help in making your food even more delicious.

Can I use Pam on cast iron? ›

Do not try to use nonstick sprays like Pam to season your cast iron skillet, as they contain other ingredients that aren't good for your pan.

The Best Way To Clean and Season a Cast Iron Skillet

For regular cleaning, avoid using harsh detergents or steel wool since they can remove the seasoning. However gentle dish soap and a light scrubbing with a dishcloth, sponge, or stiff brush will work.

All cooking oils and fats can be used for seasoning cast iron, but based on availability, affordability, effectiveness, and having a high smoke point, Lodge recommends vegetable oil, melted shortening, or canola oil, like our Seasoning Spray.

"You can't clean cast-iron the same way you clean stainless steel," kitchen expert and author of "Kitchen Matters," Pamela Salzman says. "It's very porous," Rach adds. "That flavor will stay in there and literally bake into the pan."

The reason given for this rule is that if you were to use soap, it would strip the cast iron of its “seasoning.” Seasoning is a layer of polymerized oil that's baked into all cast-iron cookware. It's what gives a cast-iron skillet a non-stick (really more like an “easy-release”) surface.

Most often you can clean a cast-iron pan by simply wiping it down with a dry paper towel or cotton dishcloth. If the pan is well seasoned, bits of burnt, stuck-on food will come right off. If any stubborn bits remain, scrape them off with a plastic spatula.

Even a well-seasoned pan can rust if it's left in the sink to soak, put in the dishwasher, allowed to air dry, or stored in a moisture-prone environment. There's no need to throw away a cast iron skillet that's a little (or a lot) rusty.

Food and moisture will deteriorate the seasoned surface and cause it to rust. Never put cast iron pans in the dishwasher or let them soak in a sink of water. Never put cold liquid into a very hot cast iron pan. The pan could easily crack or warp.

The black residue on a cast iron skillet isn't harmful; it's just a part of cooking with a cast iron pan. A black seasoned coating shouldn't rub off easily or affect the food, as it should form a useful non-stick surface for cooking. If residue starts to build up, however, this can affect your cooking.

Occasionally food may stick to your cast iron cookware. This can happen for a variety of reasons, such as not using enough fat or oil when cooking, using cookware that isn't well seasoned, or when breaking in new cookware that hasn't built up additional layers of seasoning.

Can you put butter in a cast-iron skillet? ›

Yes, you can season the pans for frying, sautéing, or baking in cast iron cookware like pans, pots, or skillets with butter, but it's not the right choice to season it for the first time. Butter immediately starts to smoke when added to a heated pan because cast iron can withstand a lot of heat.

Will soap ruin cast iron? Using soap will not ruin your pan. It is totally fine on enameled cast iron, and on plain cast iron, too. It's not going to destroy your seasoning.

Pros: Cast iron is durable, inexpensive, naturally non-stick if properly seasoned, distributes heat evenly and retains heat well, imparts iron to foods (an added benefit for some), and great for long, low simmering and browning. Cons: It is also reactive, and doesn't take well to acidic foods.

Stainless Steel Conducts Heat Better And More Evenly.

Multiclad stainless — a term that indicates your pan has layers of different metals — does a better job of conducting heat because of its aluminum core. Cast iron, conversely, tends to get hot where it's directly heated and stay cold where it's not.

While stainless steel is lightweight and better for acidic foods, cast iron is more durable and better for long, slow cooks and searing.

Olive oil is another popular choice for seasoning cast iron because most people probably already have it in their pantry. However, extra virgin olive oil has a relatively low smoke point, so heating it to higher temperatures will cause it to break down and turn rancid.

Olive oil is a great option for seasoning your cast iron skillet because it is affordable and easy to find. It also has a high smoke point, which means it can withstand high temperatures without burning.

For one, cast iron pans aren't perfectly smooth and foods like eggs may get stuck. For the best results, make sure to keep your cast iron pan seasoned, and preheat the skillet for a few minutes before you add any food to it. This allows the pan to heat evenly and prevents most food from sticking. Add fat as needed.

Avoid using the dishwasher, soap, or steel wool, as these may strip the pan's seasoning. Scrub off stuck-on bits: To remove stuck-on food, scrub the pan with a paste of coarse kosher salt and water. Then rinse or wipe with a paper towel. Stubborn food residue may also be loosened by boiling water in the pan.

How often should you season your cast iron skillet? Generally, we recommend seasoning your cast iron about once per month, but after every time you use it works as well if you find that it could use some seasoning. What type of oil is best for seasoning a cast iron skillet? Canola, vegetable, or coconut oil are best.

Why do chefs use cast iron pans? ›

Why Use Cast Iron? Cast iron is ideal for frying and baking because it holds heat much longer than aluminum pans. The food in contact with the pan will sear nicely, while the food above it will cook through radiant heat. This is possible because of the high melting point of the cast iron material.

Is There Anything You Shouldn't Cook in Your Cast-Iron Skillet? Experts Weigh In. While there's nothing that's technically off limits, the pros say you should be careful with acidic foods, like tomato or wine sauce, which can corrode the seasoning if left in the pan for too long.

Professional chefs use cast iron due to its many advantages. Besides being durable and inexpensive, cast iron pans and pots are easy to clean and great at heat retention. These features allow chefs to whip up several meals, especially those that need low simmering and browning to prepare.

While today, to some, cast iron may feel like specialty equipment, it was a predominant cooking vessel in the United States up until the early to mid-1900s, when nonstick pans became popular due to the invention of Teflon, and competition in the cookware space increased.

“With the hustle and bustle of a busy restaurant, [stainless steel] is durable and can withstand a ding or two and doesn't need as much care as cast iron,” she said. “Cast iron is heavy, which becomes tiresome when working on the line.” "They are ancient cookware. It is a thing of the past."

"You can't clean cast-iron the same way you clean stainless steel," kitchen expert and author of "Kitchen Matters," Pamela Salzman says. "It's very porous," Rach adds. "That flavor will stay in there and literally bake into the pan."
