Cast iron pans, often interchangeably referred to as cast iron skillets, are more than just kitchenware; they are a testament to culinary history and a versatile tool that promises unmatched flavor and technique. From professional chefs to home cooks, these pans have always had a devoted following. They are deeply rooted in culinary traditions and their popularity is only growing in modern kitchens. With the ability to hold and distribute heat evenly and transition seamlessly from stovetop to oven, cast iron pans are indispensable for a wide array of dishes. In this publication, we'll delve into the resurgence of cast iron in contemporary cooking, the unique health benefits it offers over non-stick pans, top brands to consider, and essential care tips including seasoning and oiling.
While non-stick pans and other advanced cookware have made their mark in the kitchen world, cast iron pans have seen a resurgence in popularity. They provide even heat distribution and can withstand incredibly high temperatures, making them ideal for searing, frying, baking, and even slow-cooking. This adaptability means a single cast iron pan can be a multipurpose tool in the kitchen, taking you from stovetop to oven with ease.
One often-overlooked advantage of using cast iron pans is the health benefits they offer over conventional non-stick pans. While modern non-stick cookware can be convenient, it often comes with its own set of health-related concerns. Below, we'll explore some of the reasons why cooking with cast iron can be a healthier option.
Many non-stick pans are coated with synthetic materials like polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon. When overheated, these coatings can break down and release toxic fumes. Cast iron, on the other hand, is free of chemical coatings. Its non-stick properties come from the natural seasoning process, making it a safer alternative for those concerned about chemical exposure.
Cooking with cast iron can actually contribute to your daily iron intake, an essential mineral needed for oxygen transport in the blood and muscle function. Foods that are acidic or cooked for longer periods have been shown to absorb more iron from the cast iron surface. While this shouldn't replace dietary iron sources or supplements for those who need them, it is a nice additional benefit.
Non-stick pans tend to wear out faster, especially if the coating starts to peel or gets scratched, posing another health concern. In contrast, a well-seasoned and well-maintained cast iron pan can last for generations, reducing the need for frequent replacements and thereby contributing to less waste and consumerism.
Once a cast iron pan is well-seasoned, its surface becomes naturally non-stick. This allows for cooking with less oil, which can be beneficial for those looking to reduce their caloric or fat intake. Keep in mind that you'll still need to maintain the seasoning by occasionally oiling the pan, but this is generally a small amount and a different process from adding oil for cooking.
Over the years, several brands have distinguished themselves in producing quality cast iron pans:
The longevity and performance of a cast iron pan largely depend on its care. Here's how to ensure your pan serves you for years, if not generations:
Canola oil is a popular choice for seasoning due to its neutral flavor and high smoke point, typically within the range of 400°F to 450°F. It is easily accessible and relatively inexpensive, making it ideal for regular upkeep.
Grapeseed oil is rich in polyunsaturated fats and has a high smoke point, typically within the range of 390°F to 420°F, which makes it suitable for seasoning. It is also praised for its light texture, allowing for a smooth, non-greasy layer on your pan.
Avocado oil has one of the highest smoke points among cooking oils, around 520°F, making it an excellent choice for seasoning your cast iron. Its rich content of monounsaturated fats contributes to a durable seasoning layer, and its neutral flavor profile won't interfere with your culinary creations. It's a premium oil, so it may be a bit more expensive than other options but offers high-quality results.
Both of these oils are similar in that they are flavorless and have high smoke points, typically within the range of 440°F to 450°F. They are less common but work well for seasoning if they're what you have on hand.
Although commonly used in deep-frying, peanut oil's high smoke point and neutral profile make it another suitable candidate for seasoning your cast iron cookware. Its smoke point is generally around 440°F to 450°F
This is often a blend of several different types of oils and is usually on the neutral side, both in terms of flavor and smoke point. Generally, the smoke point for common vegetable oil ranges from approximately 400°F to 450°F. It's a good all-around choice if you don't have any of the above specific oils available.
Corn oil has a mild flavor and a high smoke point of approximately 450°F, making it a good option for seasoning. However, it's less commonly used for this purpose compared to the other oils listed here.
Crisco Shortening is an old-school choice that many cooks swear by for seasoning and oiling cast iron. It has a high smoke point, generally around 360-370°F, ensuring that it can withstand the heat needed to polymerize and form a protective layer on your pan. Since Crisco is a hydrogenated vegetable oil (a solid fat), make sure to spread it thinly and evenly for the best results and to avoid any uneven or sticky layers. As with the other oils mentioned above, Crisco Shortening can also be used for both seasoning and regular maintenance oiling.
Olive oil has a smoke point that can vary widely depending on its quality and type. Extra virgin olive oil generally has a smoke point between 325-375°F, which is lower than the other oils listed here. However, "light" or "refined" olive oil can have a higher smoke point, ranging from 420-470°F.
Because of the variability in smoke point and the fact that extra virgin olive oil can impart a strong flavor, it's generally not the first choice for seasoning cast iron. That said, it's not completely out of the question and some people do use it successfully, especially for maintenance rather than the initial seasoning.
It's worth noting that while the smoke point is an important consideration, it's not the only factor to take into account when choosing an oil for seasoning. The type of fats in the oil, its availability, and price are also considerations. For instance, olive oil is rich in monounsaturated fats and has health benefits that could make it a more appealing choice for some people, despite its lower smoke point.
Oil sprays offer a quick and convenient way to apply a uniform coating of oil to your cast iron cookware. Brands currently offer sprays for canola oil, avocado oil, vegetable oil, and olive oil. With a simple press of a nozzle, you can easily cover the entire surface of the pan, even getting into those hard-to-reach corners and edges. While some sprays may contain additives or propellants that are considered safe for consumption, there are also options for pure oil sprays that avoid such substances. Whether you're in a rush or simply prefer the ease of a spray, these cans can be a handy tool in your cast iron maintenance arsenal.
Bacon grease has been a topic of discussion among cast iron aficionados for years. While not a conventional choice for seasoning, bacon grease holds a kind of old-school allure. The grease is saturated fat, and it tends to solidify at room temperature. This can be advantageous when you're aiming to form that protective, non-stick layer on the pan. Furthermore, bacon grease can infuse your future cooking adventures with subtle smoky flavors.
However, there are some downsides. Bacon grease has a lower smoke point compared to oils like avocado or canola, generally around 370°F. A lower smoke point could potentially lead to a less durable seasoning layer. Furthermore, using bacon grease might limit the kinds of dishes you prepare in the pan afterward, as the bacon flavor could be imparted to lighter dishes like fish or desserts.
In summary, bacon grease can be used for seasoning a cast iron pan, but it comes with its set of pros and cons. If you like the idea of a pan with a hint of bacon flavor, then go ahead and use it. Otherwise, the oils outlined in the previous section offer more neutral options that are effective for seasoning.
Seasoning and oiling your cast iron isn't just a one-time task; it's an ongoing process that ensures your pan remains non-stick, rust-free, and durable. Each type of oil or fat you might choose has its own characteristics, including smoke point, texture, and flavor profile. While high smoke point oils like avocado and grapeseed are optimal for that hard, protective layer, bacon grease and olive oil offer nuanced flavors if you prefer your pan to carry a culinary signature.
So the next time you cook up a storm in your kitchen, whether you're a professional chef or a home cook, remember that your choice of seasoning isn't merely functional—it can also be an expression of your cooking style and palate.
Note: Always consider potential allergens when choosing your oil, especially in shared kitchen environments. Peanut oil, for example, might not be the best choice if someone in your household has a peanut allergy.
With this expanded knowledge on seasoning and oiling options, you are well-equipped to take on the noble task of maintaining your cast iron pans, ensuring that they serve you well for years and even generations to come. From the traditional to the unconventional, there's a whole world of choices to explore, each contributing to the unique character of your indispensable cast iron cookware.
Determining the "best" oil for seasoning a cast iron pan can be subjective, depending on various factors such as the durability of the seasoning you desire, the types of foods you'll be cooking, and even your personal health preferences. However, here are some key considerations:
Oils with high smoke points tend to create a more durable seasoning. Avocado oil, for example, has a high smoke point of around 520°F, making it excellent for building a long-lasting seasoning layer. Grapeseed oil and safflower oil also have high smoke points, typically within the range of 390°F to 450°F, and can be excellent options for seasoning.
A neutral flavor profile is often preferred so as not to interfere with the flavors of the foods you're cooking. Canola oil and vegetable oil are often cited for their neutral flavors and are generally effective for seasoning.
While avocado oil and grapeseed oil may be superior in some aspects, they are also typically more expensive and not as readily available as canola or vegetable oil. If you're seasoning your pans frequently or have multiple pans to maintain, cost and availability may be important factors.
If you have specific health concerns or dietary preferences, like a low saturated fat intake, you may lean towards oils that are high in polyunsaturated or monounsaturated fats, such as avocado oil or sunflower oil.
Many people swear by traditional choices like Crisco shortening or even animal fats like lard and bacon grease. While these may not be the "best" in terms of smoke point or health factors, they do have a long history of effective use.
While there is no single "best" oil that will be perfect for everyone in every situation, avocado oil is often recommended for its high smoke point, durability, and neutral flavor. However, the best oil for you may depend on your specific needs and what you’re looking to achieve with your cast iron cookware.
To season a cast iron pan using Canola Oil, follow these steps:
By following these steps, your cast iron pan will develop a non-stick surface, making it a versatile and reliable tool for your kitchen.
