The Ultimate Guide to Seasoning and Maintaining a Cast-Iron Skillet

Mastering the art of seasoning and cleaning a cast-iron skillet can extend its lifespan for decades, potentially becoming a family heirloom. Unlike modern skillets, cast iron doesn’t come pre-treated with a non-stick coating. For those who prefer soaking their cookware, ceramic or stainless steel frying pans might be a better fit. While cast iron works well on induction stoves, those seeking low-maintenance options might consider a dedicated induction cookware set to avoid the seasoning process.

Though cast-iron skillets require extra care, the results are worth it. Explore expert advice from seasoned chefs on how to properly season and clean your cast-iron skillet, ensuring it stays in pristine condition for years to come.

Frequency of Seasoning and Cleaning Your Cast-Iron Skillet

Optimal Times for Seasoning

To maintain your cast-iron skillet, season it monthly or after every use. While a full seasoning process isn’t necessary each time, rinsing and applying a light coat of oil after cooking will keep it in great condition.

Re-season your skillet if it’s used often, cleaned thoroughly, appears dry, or hasn’t been used for an extended period. This ensures its longevity and performance.

When to Clean Your Skillet

Clean your cast-iron skillet after every use to avoid food residue buildup. For light messes, a simple wipe suffices, but for tougher grime or stuck-on food, a thorough scrub is recommended.

Key Points to Consider Before Starting

Seasoning your cast-iron skillet is essential for achieving non-stick, flavorful cooking. "Seasoning involves baking oil onto the cookware to form a natural non-stick layer," says Kris Stubblefield, a chef at Lodge Cast Iron.

Certain cast-iron skillets and cookware sets, like those from Lodge, come pre-seasoned from the factory and are ready for immediate use. Others, however, require an initial seasoning process before they’re cooking-ready.

Essential Supplies You'll Need:

For Seasoning:

• Cooking oil
• Lint-free cloth or paper towels
• Oven

For Cleaning:

• Nylon scrubbing brush
• Dish soap
• Lint-free cloth

Step-by-Step Guide to Seasoning a Cast-Iron Skillet With Oil

Transform your skillet into a non-stick surface by applying cooking oil and baking it (follow the instructions below). While the skillet won’t immediately develop a glossy black finish after baking, drying it with paper towels will prepare it for use. Each time you heat oil in the skillet, you’ll strengthen the non-stick layer, and you can speed up the process by seasoning frequently or using a seasoning spray.

The great news: Keeping your cast-iron skillet seasoned is straightforward for home chefs. "The most effective way to preserve your cast-iron cookware’s seasoning is by using it regularly," Stubblefield explains. "Every meal you prepare enhances the skillet’s seasoning. If you notice the surface losing its shine or food beginning to stick, it’s a sign to re-season it."

Step 1: Apply Oil Evenly

Begin by coating the entire skillet with a thin layer of cooking oil. Neutral oils like vegetable, canola, avocado, or peanut oil are ideal. For most skillets, approximately 1/4 to 1/3 cup of oil should suffice.

Step 2: Distribute the Oil

Use a lint-free cloth, clean rag, or paper towel to evenly spread the oil across the skillet, ensuring the exterior and handles are fully covered.

Step 3: Bake the Skillet in the Oven

Preheat your oven to 450°F. After coating the skillet with a thin layer of oil, place it upside down on the oven rack and bake for one hour.

Step 4: Allow to Cool and Dry

Turn off the oven and let the skillet cool completely—it will be extremely hot. Once cooled, your skillet is fully seasoned. Dry it thoroughly with a towel or paper before storing it for future use.

How to Clean a Cast-Iron Skillet Using Dish Soap

Some may argue that cast-iron pans shouldn’t be cleaned, but "just like any other cookware, cleaning your cast iron is essential to maintain it between uses," Stubblefield advises. This rule also applies to cast iron tea kettles. However, the cleaning process differs slightly, and cast iron should never be placed in the dishwasher. Even on a gentle cycle, the heat and detergents can damage the seasoning, ruin the finish, and lead to rust.

Step 1: Scrub the Skillet Thoroughly

After cooking, promptly hand-wash and scrub your cast-iron skillet. "Wash the cookware with hot water and a nylon brush," Stubblefield recommends. "A small amount of soap can be used if necessary."

Step 2: Dry the Skillet Completely

Immediately dry your skillet after washing, ideally using a dedicated towel that can absorb any oil stains. "Ensure it’s thoroughly dried with a lint-free cloth," Stubblefield advises. Allowing water to remain on the skillet can cause damage.

Step 3: Apply a Light Coat of Oil

Once the skillet is washed and dried, reapply a small amount of oil to maintain its condition. "Lightly oil the entire skillet, including the handles. A little oil goes a long way in preserving the seasoning," Stubblefield explains.

Tips to Maintain Your Cast-Iron Skillet’s Cleanliness

If you’re unsure about cleaning your cast-iron cookware correctly and want to extend its lifespan, explore these expert cleaning and maintenance tips, including insights from professional chefs.

Ensure It Stays Dry

Avoid soaking your cast iron, as it can cause rust stains in your sink. "Limit its exposure to water. Dry it immediately and apply a light coat of oil to maintain the seasoning," advises chef Mareya Ibrahim.

Scrape Off Residue Thoroughly

Utilize scrapers, scrubbers, or coarse salt to eliminate stuck-on food. After preparing sauces or searing meat, Ibrahim recommends promptly scraping out any leftover residue to prevent moisture absorption. For extremely hot pans, use a wooden or silicone spatula to safely remove debris.

Remove excess oil deposits as well. "If overcooked oil builds up, heat the pan, add salt, and scrub with a dry cloth," advises chef Allen Dabagh of Brooklyn's Boutros. "This method breaks down the oil without harming the years of seasoning you’ve built up."

Steer Clear of Metal Utensils

Refrain from using metal utensils in your cast-iron skillet. "Opt for softer materials like silicone or wood," Ibrahim suggests. Metal tools can scratch the pan’s surface and damage its protective coating.

Store in a Moisture-Free Area

Keep your cast-iron cookware as dry as possible. Avoid storing your skillet above the stove, where condensation or airborne particles can harm it.

"Store your cast-iron pan in a dry place, away from moisture," Ibrahim advises. "I place mine in a cabinet with my other pots and pans, using a soft protector to prevent scratches." This also prevents fresh oil and seasoning from transferring to other stacked skillets.

Ideal for Stovetop-to-Oven Cooking

Since cast iron is metal, never microwave it, even for a few seconds. However, it’s perfect for stovetop and oven use, making it versatile for various cooking methods.

"Cast iron seamlessly transitions from stovetop to oven. Its heavy base retains heat effectively and enhances flavors wonderfully," says Ibrahim, who frequently prepares skillet hash with oven-finished eggs or bakes apple pie with a perfectly crisp crust in cast-iron skillets. (The iron in the skillet also adds a unique flavor).

Clean It Yourself

When washing dishes, take responsibility for cleaning the cast-iron cookware yourself. Someone unfamiliar with cast iron care might soak the skillet in water. "Clean it differently from other cookware," Ibrahim recommends.

Eliminate Rust

If your cast iron accidentally ends up in the dishwasher, don’t worry—it can still be saved. Lodge suggests removing rust with steel wool or by scrubbing thoroughly, drying, and re-seasoning. Bake the skillet upside down in an oven at 500°F for one hour, then let it cool inside the oven. With proper maintenance, a cast-iron skillet can last for generations.
