Cooking with Cast Iron

frittata or pizza

I do not consider myself a chef.

Well, not really. I’m still learning. Like many men, I got my start in cooking by boiling water. Then came popping popcorn on the stove and eventually I graduated to bacon and scrambled eggs. In college I played with the great-in-theory George Foreman, but was constantly frustrated as it left my meats dry and was a total pain to clean. Settling back into a lazy routine, I resorted to making salami sandwiches innumerable with the occasional package of Ramen (Or even Zatarains!)

Marriage opened up new possibilities and I found myself frequently manning the grill. I like the grill for its cleaning ease. Grilling is an art I hope to one day perfect — is there any accomplishment for a man more envious than that of a seasoned grillmaster? Sure. Like killing a grizzly bear with nothing but your wits and bare hands.

One day.

In the meantime, my cast iron skillet is my the primary weapon in my cooking arsenal — I use mine daily and continually find new uses for it.

For those unfamiliar with the wonders of a cast iron skillet, they have great heating properties thanks to the material: heat is well distributed by iron, which makes for a relatively even cooking surface. The heavy duty nature of cast iron skillets makes them heavy beasts. My Lodge 12 incher tips the scales at over 7 lbs. They often come pre-seasoned giving the skillet a blackish color rather than the dull gray of raw iron.

What’s the deal with seasoning a skillet? Cast iron is porous. Being iron, its also susceptible to rusting if exposed to the elements. Seasoning a skillet is getting a layer of oil and fat into the porous iron and between the iron and everything else. You want the fat layer, which is why you do not use soap to clean your skillet! You read right. And I know what you’re thinking: how can you clean anything without soup?

With the cast iron skillet, you learn to accept soapless cleaning. Most of the time, I just use a brush and hot water to get my skillet clean. Other times, I might boil some water on the skillet and then scrub it clean. The beauty of the oil/fat coating on the skillet is that it makes clean-up a pretty painless process. Once you scrub the skillet clean, you just dry it off. If the skillet looks too dry, you will want to rub some oil onto it.

And this brings me to an important tenet of cast iron cooking — an admonishment you might not find in too many other places — that is that you should avoid cooking with vegetable oil at all costs, specifically when using a cast iron skillet. Despite the many good reasons to avoid vegetable oils, the main one I’m concerned with is that vegetable oils are high in polyunsaturated fatty acids (PUFAs), which due to their abundance of easily broken double-bonds, lead to the production of unnatural byproducts when repeatedly heated. In other words, if you’re leaving the oils on your skillet, you want those oils to be robust enough to handle repeat heatings. Vegetable oils just aren’t up to the task.

Olive oil, having a lot of monounsaturated fatty acids, is a better choice. However, I’ve found that it tends to smoke at lower temperatures. And MUFAs still have at least one easily broken double-bond, which makes the fat molecules prone to deteriorate over time from reheating/reusing the skillet.

Luckily there are some good alternatives. Cook some bacon. The grease that remains is high in saturated fats. Let that skillet soak it up! Though I’m not the biggest fan of reusing bacon grease, I have re-used it intra-day; in other words, if I had bacon for breakfast I’ve reused the grease later that day to cook pork chops or steak in the skillet.

Since fresh bacon grease is hardly handy all the time, I was happy to discover coconut oil. Coconut oil must be one of the greatest unsung heroes of the oil kingdom. I’ve blogged about the apparent goodness of coconut oil before (here and here). Now that I’ve been using coconut oil on my skillet for a good month or two, I’ve got nothing but praise for it. I find my skillet easier to clean, less prone to smoking, and coconut oil to make for an excellent medium. It is, without a doubt, the cast iron oil of choice.

With all of this talk about using a cast iron skillet, the question that remains unanswered is: what are you cooking?

I’m still finding new things to cook on mine all the time. Going forward, I hope to share some of my favorite cast iron dishes. For now, here’s a list to get your juices flowing:

  • Bacon. Is there anything more cast iron basic than that?
  • Spinach. Particularly at the end of cooking some meat — drizzle some olive oil on it if you want.
  • Pork chops. Having grown up eating plenty of grilled pork chops, I was convinced that they were doomed to being the other dry white meat. I’m happy to report that the skillet delivers a mean, juicy pork chop!
  • Steak. Wowie this is good one that draws on searing the steak and using an oven or grill to round out the cooking.
  • Fish (i.e. salmon). Fast, easy, flavorful and creating a nice crispy crust.
  • Broccoli/Cauliflower. A brief sautee makes for a tasty side.
  • Bratwurst. Faster than the grill – just as delicious.
  • Flank steak fajitas. Need I say more?
  • Taco meat. Ground beef plus diced jalapeno peppers. Mmm.
  • Meatballs. “You like-a my spicy meat-a-balls!”
  • Cornbread. My dad’s recipe. It cannot be beat.

In short, though I’ve a ways to go to being a chef, I’ve made it leaps and bounds thanks to my trusty cast iron skillet. Its versatility, ease of use, and the quality of food it produces is unmatched. It’s also great in that it doesn’t require firing up a grill or oven to make great, quick meals for one to four people. For would-be-chefs like me, learning to cook with cast iron is a blast.

This post should serve as an introduction to my favorite piece of cookware. Going forward, I’ll be able to jump right into explanations of how to cook specific delectable dishes with cast iron.

Stay tuned!

More on Coconut Oil

Before I go into the details, here are my big takeways:

  • Cook with coconut oil — try it instead of olive oil for sauteing fish, beef, pork, etc.
  • The medium-length saturated fats in coconut oil are good for “quick energy” because they require little digestion before being quickly absorbed into the body. I cooked with coconut oil at lunch today and was sort-of jazzed all afternoon. Further testing will be required. Addendum: Found this abstract of a study on medium-chain triglycerides: the study showed a 12% rise in basal metabolism on MCTs as compared to only a 4% rise for LCTs.
  • Once again fats win out over carbohydrates. And with even more tasty fats to choose from, its only that much more compelling to jettison the crummy carbs from my diet.

The Details

I picked up some coconut oil from Wal-Mart yesterday. Mind you, it was hardly the uber-natural, ultra-low-processed stuff I should be buying, but I only realized that today. I’ll work on getting the good stuff later; in the meantime, the Louana brand will do just fine.

As curious as I am, after reading the afore-blogged glowing review of oils high in saturated fats, and coconut oil in particular, I had to learn more. Some basic googling led me to this page, which ugliness aside, is pretty informative. Here’s a hearty snippet, as emphasized or edited (…) by me:

Coconut oil is one of the most stable oils you can buy. It does not turn
rancid easily. … coconut oil was one of the foods Weston Price studied in his journeys. He discovered that the coconut was considered, by the local populations, a medicine food. He found that those civilizations that consumed coconut regularly had no knowledge of cancer, heart disease, arthritis, and diabetes.

Let’s take a look at the healing properties of coconut oil:

  • Coconut oil is antiviral, antifungal (kills yeast too) and antibacterial. It attacks and kills viruses that have a lipid (fatty) coating, such as herpes, HIV, hepatitis C, the flu, and mononucleosis. It kills the bacteria that cause pneumonia, sore throats, dental cavities, urinary tract infections, meningitis, gonorrhea, food poisoning, pneumonia, and many, many more bacterial infections. It kills the fungus/yeast infections that cause candida, ringworm, athletes foot, thrush, jock itch, diaper rash and more.
  • Coconut oil is called the “low fat” fat. … It boosts one’s energy and endurance. Many athletes use it blended into their drinks. It also supports thyroid function and increases your metabolism (great if you want to lose weight).
  • Coconut oil improves digestion and absorption of fat soluble vitamins, minerals (especially calcium and magnesium), and amino acids. It improves the body’s use of blood glucose and improves insulin secretion and absorption (great for type II diabetes). In fact, many diabetics (type I and type II) use it to reduce their symptoms. One’s risk of diabetes decreases with regular use of coconuts and coconut oil. And as we already mentioned, cooking with coconut oil does not create any harmful byproducts.
  • Coconut oil helps the body heal and repair faster. It aids and supports immune function, protecting us from a variety of cancers.
  • Coconut oil, contrary to much hubbub, is good for your heart. It keeps our blood platelets from sticking together (and causing dangerous clots). Regular users of coconut oils have a much lower chance of atherosclerosis (clogging of the arteries), arteriosclerosis (hardening of the arteries), and strokes. Coconut oil can lower your blood pressure.
  • Coconut oil is a natural antioxidant. It protects the body from free radical damage and prevents premature aging and degenerative diseases.
  • Finally, coconut oil is the best massage oil on the planet. What it does to your skin, you simply have to witness. It forms a barrier against infections, softens and moisturizes your skin, and prevents wrinkling, sagging, and age spots. It promotes healthy hair and complexion, protects from any damaging UV rays. …


These are some pretty extravagant claims. And unfortunately, they were not footnoted or referenced. A book by Bruce Fife was mentioned (See the nearest match available on Amazon, to the right), which might go into detail on some or all of these claims.

Setting aside some of the more panacea-esque claims, its hard to miss the correlation between consuming coconut oil and preventing metabolic syndrome (A.K.A. “diseases of civilization”), which may be linked to loss of insulin sensitivity or the damage of abundant insulin, which we know is linked to eating carbohydrates. Though I can only speculate as to cause-and-effect, its reasonable to assume that cultures whose diets have a higher percentage of fats in them relative to carboyhdrates are less likely to succumb to the problems associated with insulin (hypertension, diabetes, obesity, cardiovascular disease, etc. — metabolic syndrome).

The bacteria-destroying aspect of coconut oil is intriguing, as well. I understand why saturated fats naturally have a longer shelf-life (Lack of easily broken, carbon=carbon double-bonds), but I can’t help but wonder if another reason coconut oil takes so long to go rancid is some anti-bacterial trait of the oil, itself.

All about oils, Coconut milk and Whiskey

Just found an informative read about fats and oils over at Mark’s Daily Apple written by guest poster Scott Kustes of Modern Forager.

In the post, Kustes explains that the molecular bond stability of saturated fats makes oils high in saturated fats ideal for cooking.

Amongst the four types of fats, saturated, monounsaturated, polyunsaturated and trans, (trans being the only unequivocally bad fat), the lack of double-bonds in a saturated fat molecule makes it less prone to degenerating / breaking down when left sitting around or cooked.

On the other hand, monounsaturated fats have one double bond (See this graphic, bottom molecule for an example of a monounsaturated fat) and polyunsaturated fats have multiple double bonds. Double bonds are easier to break, so mono- and, even moreso, polyunsaturated fats are more unstable.

The big takeaway? When reaching for oils for cooking, coconut and palm oils as well as animal fat are all ideal choices as they consist of mostly saturated fats and monounsaturated fats (more of the former than the latter, at that).

Another interesting takeaway was that the the short chains of saturated fats found in coconut milk (or oil) are immediately absorbed into your blood via your stomach, resulting in a boost of energy which can noticeably raise body temperature, metabolism, etc. I might have to try that one out and see what happens. Makes me wonder if coconut milk might be an ideal beverage for endurance athletes who need an energy boost.

One other thing I learned whilst scanning Mark’s Daily Apple: apparently, whisky, gin, vodka, scotch, and 100% agave tequila all have zero carbohydrates. I was immediately a little skeptical as I find Maker’s Mark to be a bit sweet — but upon checking it out, yep, zero carbohydrates (I consider Maker’s Mark my reasonably affordable whiskey of choice).

Tequila shots anyone?
