A cast-iron pan is one of the most versatile and efficient cooking tools you can own. No other material matches its ability to conduct and retain heat, making it perfect for caramelized seared steaks, crispy-edged skillet cornbread, and flavor-packed dishes. Plus, it transitions seamlessly from stove to oven, grill, or even a campfire.
Cast iron is naturally nonstick and incredibly durable. As Ree notes, “It will last forever if you take good care of it—and even if you don’t, you can revive it with a little effort!” This involves knowing how to properly clean a cast-iron skillet and season it to keep its surface rust-free and nonstick for all your favorite cast-iron recipes.
Do you know how to season cast iron? While it might seem daunting at first, the process is simpler than you’d expect. Seasoning involves baking oil into the pan to maintain its signature black patina. Many high-quality cast-iron skillets come pre-seasoned, but regular seasoning is key to preserving their performance after use. The good news? With just a few easy steps, you can keep your skillet in excellent condition for years.
A Step-By-Step Guide to Seasoning Cast Iron
Whether you’re seasoning a brand-new pan or refreshing an old one, follow these six simple steps:
- Preheat your oven to 400°F. Thoroughly wash the skillet with hot, soapy water, and dry it completely.
- Apply a thin, even layer of vegetable oil or shortening to the skillet, removing any excess.
- Adjust the oven racks so there are two positioned at an equal distance.
- Place a sheet of foil on the lower rack to catch any drips.
- Position the skillet upside down on the top rack.
- Bake the skillet for one hour, then turn off the oven and allow the pan to cool inside.
The Best Oil to Use to Season Cast Iron
You can use any oil or fat to season cast iron, but neutral oils with a high smoke point work best. Since the skillet will be baked at high temperatures, options like vegetable oil or shortening are ideal. These are affordable, effective, and less likely to cause smoke than lower smoke point oils like olive oil.
How Often to Season a Cast-Iron Pan
The frequency of seasoning depends on how much you use the pan. If you notice signs of rust, a sticky residue, or a dulling nonstick finish, it’s time to season your skillet again. For extensive rust, consider using a cast-iron rust eraser before reseasoning. The same process applies to cast-iron grill pans.
What to Cook in a Cast-Iron Pan
The best way to maintain your skillet’s seasoning is to use it regularly. Cooking foods with fat—like oil, shortening, or butter—will naturally add seasoning to the pan. Frying bacon or searing steaks not only enhances the skillet’s nonstick coating but also lets you enjoy delicious meals while caring for your cast iron.
