Properly maintained, a cast iron skillet can last a lifetime. We've covered the science and method of cast iron seasoning before, but we thought we'd revisit this essential technique for anyone who's new to cast iron or simply needs a refresher.
What You Need
Cast iron skillet
Sponge or stiff brush
Clean, dry cloth or paper towels
Vegetable oil or shortening
1. Preheat oven to 325°F.
2. Wash the skillet with warm, soapy water and a sponge or stiff brush. (Cast iron should not normally be washed with soap, but it's fine here since the pan is about to be seasoned.)
3. Rinse and thoroughly dry the skillet.
4. Using a cloth or paper towel, apply a thin coat of vegetable oil or melted shortening to the inside and outside of the skillet.
5. Place the skillet upside down on the oven's center rack.
6. Place a sheet of aluminum foil below the rack to catch any drips.
7. Bake for an hour.
8. Turn off heat and allow to the skillet to cool completely before removing from oven.
Additional Notes: A seasoned skillet is smooth, shiny, and non-stick. You'll know it's time to re-season if food sticks to the surface or if the skillet appears dull or rusted.
Tomorrow, we'll look at how to clean cast iron.
