Ingredients

  • Cast iron pan
  • 1 raw potato sliced in half
  • 2 tablespoons salt
  • 1-2 tablespoons cooking oil with a high smoke point flax, grapeseed and peanut oils work well
  • paper towels
  • Wooden or metal flat-edged spatula

Instructions

  1. Preheat oven to 400 degrees F. Start by using a spatula to scrape any food residue from the surface of the pan. If your pan is mostly clean it can be wiped out with a damp cloth. Never use soap on your cast iron cookware.
  2. Sprinkle the salt into the pan.
  3. Using the flat side of the potato, scrub the salt into the surface of the pan. The moisture from the potato, combined with salt, helps to remove any debris or rust that cannot be eliminated by simply wiping out or scraping.
  4. Use a slightly damp paper towel to wipe the salt from the pan.
  5. Once the salt has been removed and the pan is dry, pour in the oil.
  6. With a paper towel wipe the entire surface of the pan, including the inner sides, edges and handle, with the oil. The surface should be lightly coated in oil, with no excess oil pooling anywhere. Wipe out all of the excess oil before placing in the oven.
  7. Once the pan has been thinly coated with the oil, place it in the oven at 400 degrees F for one hour. Allow the pan to cool and wipe out any excess oil that may be left behind. For pans that have been completely stripped of their seasoning, you may need to repeat the oiling and heating process multiple times to build up a thicker layer of protection. Do not use too much oil on the surface of the pan-- it should be thinly coated, not dripping.
  8. Once your pan is cool and you've wiped out any excess oil, your cast iron is cleaned, seasoned and ready to use! Every time you cook with oil in your cast iron pan (deep frying, sauteing, etc.) you will continue to build the non-stick coating, making it better with age.
  9. You do not need to re-season your pan each time you use it. Once you've cleaned it after cooking (using the instructions above), wipe it with a thin layer of oil before storing. This will help to keep the seasoning intact between uses. Re-season the pan once every 15-20 uses, or whenever you start to notice foods sticking more and/or the seasoning wearing away.
