You’re ready to season your cast iron skillet but there’s a catch: all you have is coconut oil. You’re left wondering, “Can I really use this for seasoning?”

Absolutely, coconut oil will do the trick! And don’t just take our word for it—our detailed step-by-step guide will walk you through the process, showing you exactly how coconut oil can be your skillet’s best friend.

Countless cooks have turned to coconut oil for seasoning, drawn by its high smoke point and natural benefits. Our guide compiles the best practices and tips, ensuring you achieve a perfectly seasoned, non-stick skillet ready for any culinary challenge.

Effectiveness of Coconut Oil Seasoning

You’ve got your cast iron skillet in hand, coconut oil at the ready, and a question on your mind: “Is coconut oil the secret ingredient to the perfect seasoning?”

The answer is a resounding no, there are better alternatives such as my two favorites:

  • Avacado oil
  • Flaxseed oil

However coconut oil is still a great choice and here’s the lowdown on why it’s not just a good choice but a great one.

The Magic Behind Coconut Oil

First off, let’s talk about what makes coconut oil a standout contender. It boasts a high smoke point—350°F (177°C) for the unrefined stuff and up to 400°F (204°C) if you opt for refined.

This is key for seasoning, as the oil needs to withstand high heat to form that desired, protective non-stick layer on your skillet.

But it’s not just about the heat. Coconut oil is packed with saturated fats, crucial for creating a slick, durable surface that lets you flip pancakes with ease and clean up in a snap. It’s this combination of high smoke point and fatty acid richness that puts coconut oil in the seasoning spotlight.

Diving Deeper

But why exactly does coconut oil work so well? When you heat your skillet, the coconut oil transforms, bonding to the metal in a process called polymerization. This isn’t just science jargon; it’s what gives your skillet that non-stick quality everyone raves about.

Here’s what you get with coconut oil seasoning:

  • Durability: A layer that lasts through countless meals.
  • Rust Resistance: Less moisture means less rust, extending your skillet’s life.
  • A Hint of Sweetness: Coconut oil can add a subtle flavor that enhances, rather than overwhelms, your dishes.

I’ll never forget the first time I seasoned a skillet with coconut oil. It was an old, neglected piece that I wanted to bring back to life.

Skeptical but hopeful, I followed the steps, and the transformation was nothing short of miraculous. It wasn’t just about reviving the skillet; it was a lesson in the wonders of coconut oil.

Now let’s move on to choosing the right type of coconut oil!

Step #1 Choosing Your Coconut Oil:

Crafting the perfect guide for seasoning your cast iron skillet involves a deep dive into the foundation of the process: selecting the right coconut oil.

This choice is more than a mere preference; it’s about understanding the nuances between refined and unrefined coconut oil and how they impact the seasoning outcome.

Refined Coconut Oil

Refined coconut oil is the product of processing and refining, resulting in an oil that boasts a higher smoke point 204 °C / 400 °F and a more neutral flavor.

This makes it particularly well-suited for seasoning cast iron skillets, where high heat is used to polymerize the oil into a protective, non-stick layer.


Unrefined Coconut Oil

Unrefined coconut oil, also known as virgin coconut oil, is less processed than its refined counterpart, retaining more of its natural flavor and aroma.

While these characteristics make it desirable for certain culinary uses, they pose limitations for seasoning cast iron such as a low smoke point of 177 °C / 350 °F and a coconut flavor.

Step #2 Preparation of Your Cast Iron:

The initial cleanse of your cast iron is a step of paramount importance.

This stage is about removing any barriers that might impede the seasoning oil from fully penetrating the pores in the cast iron.

For New & old Skillets

New cast iron skillets often come with a layer of wax or a factory-applied coating to protect them before they find their home in your kitchen.

This protective layer is essential for keeping the skillet rust-free before it’s purchased but must be removed to allow seasoning to take place.

However if you have an old skillet, you’ll have some layer of seasoning on just from cooking in it, and we will need to ensure this is removed before we apply the coconut oil seasoning.

To ensure the seasoning is removed use one of the below methods:

  • Use the self-cleaning cycle of your oven.
  • Soak the skillet in a 50/50 mix of white vinegar and water for 1 hour then scrub
  • Scrub the skillet with steel wool and soapy water.

After the skillet has been stripped of it’s seasoning, you need to dry it thoroughly.

Any lingering moisture can lead to rust, undoing the cleansing work and complicating the seasoning process.

Step #3 Oiling the Skillet

Now that you have chosen your coconut oil and prepared your cast iron skillet, it’s time to move on to the heart of the seasoning process: oiling the skillet.

This step is critical in achieving a non-stick surface that will make your skillet a joy to cook with for years to come.

The first thing to consider is how much coconut oil to use. A common mistake is applying too much oil, which can lead to a sticky residue. Instead, aim for a thin, even layer.

Tip: A lint-free cloth works best for applying the oil, ensuring that you can spread it thinly and evenly across the surface without getting paper towel fibers blocking the pores.

Application Technique

  1. Warm the skillet slightly on the stove. This helps to open up the pores of the cast iron, making it more receptive to the oil.
  2. Apply a small amount of coconut oil to the skillet. You need just enough to coat the surface lightly.
  3. Spread the oil across the entire skillet, including the bottom, sides, and handle. Don’t forget the back of the skillet as well.

Remember, the goal is a coat thin enough that the skillet looks dry, not oily.

Step #4 Baking the skillet:

With the skillet now thinly coated in coconut oil, the subsequent phase is to bake it. This step is pivotal, as it solidifies the oil into a protective, non-stick layer.

The process differs slightly depending on the type of coconut oil used: refined or unrefined.

Understanding Oven Temperatures

Refined Coconut Oil: For skillets coated with refined coconut oil, set your oven to 400°F (204°C). Refined oil can withstand higher temperatures, which aids in the polymerization process.

Unrefined Coconut Oil: If you’re using unrefined coconut oil, a lower temperature of 350°F (175°C) is recommended. Unrefined oil has a lower smoke point, and this temperature helps prevent excessive smoking while still allowing the oil to polymerize effectively.

The Importance of Baking for One Hour

Baking the skillet for exactly one hour is critical. This duration ensures that the oil undergoes a complete polymerization process, transforming it into a durable, non-stick coating.

Polymerization is a chemical reaction where the fatty acids in the oil link together, forming a tough, plastic-like surface that adheres to the iron.

This process cannot be rushed; insufficient baking time may result in a sticky or incomplete seasoning layer.

Positioning and Preparation

Upside Down: Place the skillet upside down in the oven. This encourages any excess oil to drip off, promoting an even, smooth seasoning layer without any pooled oil spots.

Aluminum Foil: Place a piece of aluminum foil or a baking sheet on the bottom rack beneath the skillet. This catches any oil drips, keeping your oven clean and preventing any potential fire hazards from oil accumulation.

Cooling Down

After the hour has elapsed, turn off the oven but leave the skillet inside to cool down gradually with the oven.

This slow cooling process is essential. It prevents thermal shock, which could damage the newly formed seasoning layer, and ensures the polymerization process is fully completed.

Step #5 Evaluating the Seasoning:

Once the skillet has cooled, you should notice a hard, shiny surface. This indicates a successful seasoning. However, if the surface appears sticky, patchy, or uneven, it may not have been seasoned correctly.

For those instances, I’ve prepared a guide on how to address uneven seasoning on cast iron.

This comprehensive tutorial will walk you through stripping and reseasoning your skillet, ensuring optimal performance.

Final Thoughts

Seasoning your cast iron skillet with coconut oil and properly baking it transforms it into a versatile cooking tool.

The key lies in understanding the nuances of the oil you’re using, following the baking time and temperature guidelines, and ensuring your skillet is positioned correctly in the oven.

With patience and attention to detail, you’ll achieve a beautifully seasoned skillet ready for countless culinary adventures.
