Whether you’re a cooking novice or a seasoned pro, learning How to Season Cast Iron is a kitchen essential that shouldn’t be overlooked. Many people feel intimidated by the process, but it’s actually much easier than it seems. A properly seasoned cast iron pan isn’t something to fear—it’s more like creating a trusty kitchen sidekick!
In this guide, you’ll discover easy tips and secrets for seasoning cast iron and achieving that coveted non-stick surface and excellent heat retention that this cookware is renowned for.
In just a few simple steps, you’ll learn how to season your cast iron pan for the first time, how to maintain it, and how to elevate your cooking (and eating) experience.
Why Treating Your Cast Iron Pan Matters
- Cookware Longevity: To season or not to season? Seasoning creates a protective barrier that prevents moisture from reaching the raw iron, which can lead to rust and deterioration. Proper coating helps ensure your cast iron skillet becomes a lifelong kitchen companion.
- Cooking Performance: Adding that protective layer to your cast iron pan greatly enhances its functionality. A seasoned pan creates a non-stick surface, making cooking and cleanup a breeze—truly a frustration-free experience!
- Flavor Satisfaction: A well-seasoned pan does more than prevent sticking—it actually enhances the flavor of your food. The oils used in the seasoning process not only keep food from sticking but also add a depth of flavor. With each meal cooked, the layers build and develop, resulting in a unique, flavorful cooking surface.
What is Cast Iron Seasoning?
Cast iron seasoning is the process of applying a thin layer of oil to your cast iron pan and heating it to a temperature above the smoke point. This triggers a chemical reaction called polymerization, where the oil bonds to the surface of the pan, creating a durable, non-stick coating. The result is a protective layer that prevents rust and enhances the cooking surface.
Seasoning isn't a one-time event; it's an ongoing process that improves with each use. Over time, the layers build, enhancing both the flavor of your food and the performance of your cookware. This is why cast iron enthusiasts cherish their skillets—each one becomes a unique, seasoned tool in their kitchen.
Choosing the Right Oil
I’ve tried many different oils, but the key factor in choosing the best oil for seasoning cast iron is having a high smoke point—essential for effective polymerization. Here are a few oils that work well, all with a smoke point of 450°F or higher:
- BuzzyWaxx: By far my favorite! This unique blend of high smoke point oils and beeswax creates a durable layer of polymerization and leaves a beautiful sheen on your cookware.
- Canola Oil: A popular choice due to its neutral flavor, high smoke point, and affordability. It’s a go-to oil for seasoning cast iron, providing a solid and reliable coating.
- Grape Seed Oil: Known for its mild, light flavor, grape seed oil doesn’t alter the taste of food. It’s an excellent option with a high smoke point, minimal flavor impact, and richness in polyunsaturated fats, creating a strong non-stick surface.
- Crisco Shortening: Traditional shortening doesn’t impart any flavor, though butter-flavored Crisco adds a buttery taste. It’s another great choice for creating a durable, long-lasting finish on your cast iron cookware.
Disclosure: Please note that I am a part owner in BuzzyWaxx, a company that offers cast iron seasoning and care products. While I’ve shared my personal experiences with BuzzyWaxx, I encourage you to explore all options to find the one that best suits your cooking and maintenance needs.
What You’ll Need to Season Your Cast Iron for the First Time
- Cast Iron Skillet: Of course, this is essential! Whether it's new or well-seasoned, make sure your cast iron is either new or thoroughly cleaned of any old seasoning. If your pan is used, it’s important to strip it down to the bare metal before applying new layers of oil.
- High Smoke Point Oil: As mentioned earlier, each oil option has its unique properties, but they all share the ability to withstand high temperatures without burning. Choose the one that fits your budget, availability, and flavor preference.
- Other Kitchen Utensils: Aside from the skillet and oil, a few extra tools will help during the treatment process. You'll need a paper towel or clean cloth to evenly apply the oil and tongs to safely handle the hot pan.
How to Clean a Cast Iron Skillet
- Damaged or Used Skillet: Got a damaged or hand-me-down skillet in need of some love? Start by soaking it in equal parts white vinegar and water for 30 minutes. Then, use a non-scratch scrubbing pad or steel wool to gently remove any old seasoning. Rinse thoroughly, dry completely, and follow the steps in the section below to bring it back to life. Alternatively, try out this Oven Cleaning Method.
- After Cooking: While the pan is still warm, gently scrub away any food residue using a non-abrasive sponge or brush under hot water. Be sure to dry it immediately with a paper towel, then apply a thin layer of high-smoke point oil to maintain it.
Note: Avoid soaking the skillet in water, this can damage and strip the seasoning. Using soap on your cast iron is okay since soap no longer contains lye.
Step-by-Step Guide: First-Time Seasoning
Learning how to season cast iron in the oven for the first time can seem daunting, but don’t worry! Here are 3 straightforward steps to make the process simple and manageable.
Start by ensuring your skillet is thoroughly cleaned (as mentioned earlier). Next, preheat your oven to 200-350°F, gather your oil (BuzzyWaxx works great too!), and your kitchen tools, then follow along:
- Step 1: Preheat the Cast Iron. Place the skillet in the preheated oven for about 20 minutes. This gives it enough time to heat up without making it too hot to handle with an oven mitt or pot holder. After 20 minutes, remove it from the oven and increase the oven temperature to 480-500°F.
- Step 2: Apply the Oil. Using a paper towel or clean cloth, spread a thin layer of oil (or BuzzyWaxx) over the heated cast iron, covering every inch. Then, take a clean towel and wipe off any excess oil, leaving just a light trace on the surface.
Note: If using BuzzyWaxx in the metal can, rub a small amount onto a rag using a circular motion, then wipe the cast iron as described above.
- Step 3: Polymerize the Pan. Place the skillet upside down in the oven and bake for 1 hour to allow the oil to polymerize. After an hour, let the pan cool enough to handle, then repeat steps 2 and 3 two more times for optimal seasoning. Once complete, your cast iron is ready to cook!
Pro Tips for Handling a Cast Iron Skillet to Maintain Seasoning
- Oil Layer: It’s crucial to apply only a thin layer of oil. Too much oil can lead to a sticky, tacky surface because the excess oil won’t properly polymerize.
- Bake Time: Be sure to keep the pan in the oven for the full recommended bake time during seasoning. If you don’t, the oil won’t polymerize properly, which could lead to food sticking and the coating wearing off faster.
- Drying and Storage: After rinsing, don’t leave it wet to avoid excess moisture and rust. Once dry, store your cast iron in a dry place, and if stacking it with other cookware, separate it with a paper towel to prevent scratches.
- Re-Seasoning: Make it a habit to periodically re-season your skillet, especially when you notice dull spots or if food starts sticking. Regular maintenance keeps your pan in top shape.
Frequently Asked Questions
Spotting usually occurs when there’s too much oil on the skillet. Be sure to wipe away excess oil until the surface looks almost dry. Wipe it until the oil looks like it’s gone, then wipe it again for good measure to remove any remaining oil.
Flaking can happen if you used an oil with a low smoke point or didn’t heat it to the right temperature. If flaking occurs, redo the coating process starting with a good base layer. Refer to the cleaning section above for instructions on how to restore it.
For effective seasoning, use oils with a high smoke point, such as BuzzyWaxx, canola oil, grapeseed oil, or Crisco. See the oils section above for more details!
Yes, it’s normal for the seasoning to darken and develop a rich patina over time. This not only enhances the look of your skillet but also improves its non-stick properties and flavor.
No, never put cast iron in the dishwasher. The detergents and water can damage the layers and lead to rust. Always hand wash your skillet to maintain its seasoning.
