Cooking on unseasoned cast iron can result in sticking, rusting, and a myriad of other issues (some of which are outlined above). Lucky for cast-iron newbies, most skillets sold these days come pre-seasoned. Take your store-bought seasoning a step further though and add your own before you call it good to go.
Seasoning makes the pan nonstick. You definitely don't want to try using cast iron without seasoning--the porous surface makes it very sticky. Even if a pan says it's pre-seasoned, you'll get a better, longer lasting non-stick surface if you season it again yourself.
Initially, cooking in an unseasoned skillet would be a pain. Foods would stick and it would be a chore to clean. In time though, it would become seasoned from use alone. It would take some time but eventually a nice slick surface would form.
Cooking with a cast iron pan that has a little bit of surface rust on it isn't likely to hurt you. If your pan is seriously rusty or has visible rust flakes, you shouldn't cook with it until the rust is removed and the pan is washed and re-seasoned.
Eggs fall into the category of sticky foods that are not ideal for cast iron skillets that haven't built up their seasoning yet. While cast iron can become non-stick with sufficient use over time, a newer skillet will almost certainly cause your eggs to stick to its porous surface.
Washing it may help a bit, but rust is persistent. You wonder if the cast iron is safe to cook with this weekend for breakfast or if you should just toss it in the trash. The U.S. Department of Agriculture (USDA) states that rust isn't food safe, so it wouldn't be wise to ingest.
Common cooking oils like olive oil will gradually produce seasoning, but won't be as effective as grapeseed oil. Canola, other vegetable oils, and shortening are a little better.
Understanding Seasoning
Iron, on its own, is gunmetal gray and highly reactive, able to rust within minutes in humid air alone. Try to cook in a bare iron pan, and not only will the rusting be a problem, but your food will stick to it as well.
Bake your cookware upside down at 450 degrees Fahrenheit in the oven for one hour. Allow the pan to cool down completely, and repeat three more times.
Sometimes layers of seasoning may flake off your cast iron pan. This can happen if layers of seasoning have not fully bonded to the metal. If your pan is flaking, don't panic. Simply scrub the pan with a nylon brush or salt, then rinse, hand dry, and rub with oil.
Never cook acidic foods in a cast iron skillet.
You can sauté cherry tomatoes in cast iron, but don't try making a long-simmering tomato sauce. If you recently purchased your skillet and it still needs to be "broken in," acidic ingredients can erode the seasoning and even make foods taste metallic.
Cast iron cookware's disadvantages include its heavy weight, the need for seasoning and maintenance, potential reaction with acidic foods, and lack of slickness for delicate cooking tasks.

Cooking in cast iron can add a significant amount of iron to your diet. In studies, researchers found that spaghetti sauce cooked in cast iron skillets increased the iron content anywhere from 2mg to 5mg iron.
Simply put, cast iron can rust if you leave water on it for too long. You can absolutely still use water (and soap!) to cook in or clean your cast iron, but you don't want to let water just sit on your pan for an extended period of time.
You should season a cast-iron skillet at least once a month, but seasoning it after each time you cook with it also works. You may not need to repeat the entire seasoning process as you did before initially using it, but after each use, rinse it and give your cast-iron skillet a quick season by oiling it.
With proper care cast iron cookware can withstand a lifetime of use. Actually several lifetimes as these cast iron pans and dutch ovens are often passed down from generation to generation. Taking care of cast iron cookware is as easy as 1 – 2 – 3.
This might look intimidating, but remember that you really can't ruin cast iron. Even if you strip away most of the seasoning, you can still rebuild it into the sleek, nonstick skillet you expect.
Cooking on unseasoned cast iron can result in sticking, rusting, and a myriad of other issues (some of which are outlined above). Lucky for cast-iron newbies, most skillets sold these days come pre-seasoned. Take your store-bought seasoning a step further though and add your own before you call it good to go.
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.
If a crack appears in your cast iron pan, it's time to ditch it. Even a hairline crack will expand and contract when heated and cooled, and ultimately the pan will split—a potentially dangerous situation if it happens during cooking! Plus, cracks are difficult to clean and may harbor bacteria and rust.
