How to Season Cast Iron

The best way to season cast iron

Brand new cast iron, or cast iron that has lost its seasoning somehow (cooking with acidic ingredients, ran in the dishwasher, washed with too much soap or abrasive sponges, etc.) requires a refresh. Seasoning cast iron is pretty simple with the right tools.

Instructions:

  1. Warm your unseasoned pan over the stove for 10-20 minutes
  2. Use paper towels or cloth rag towel to carefully cover entire surface of cast iron with seasoning oil
  3. Insert cast iron upside down in a cool oven
  4. Set baking temperature to 500 degrees then set a timer for 1 hour
  5. Turn off the oven and let the pan cool for 2 or more hours in the oven
  6. Repeat this process at least twice and up to 5 more times to fully season your pan 
  7. Once the cast iron seasoning process is complete, your cast iron cookware should be shiny but not sticky to the touch.

Best Oils for Seasoning Cast Iron

The oil you use for seasoning your cast iron pan matters! Not all oils are created equal (I learned this from experience…). You are best off using a refined oil with a high smoke point. The most popular options are:

  1. Flaxseed Oil
  2. Grapeseed Oil
  3. Canola Oil

The most popular cast iron seasoning oil by far and away is flaxseed oil. It bonds quickly and efficiently to cast iron and can even withstand the Cook’s Illustrated dishwasher test

I can attest from research (and experience…) that it’s best to avoid seasoning cast iron with olive oil or other oils with very low smoke points. Flaxseed oil is worth the investment, just use it sparingly after each time you clean your cast iron.

If your cast iron cookware is suffering from severe rust marks, you might be best off taking it to a machine shop to have it sandblasted to its original raw state. Alternatively you can try the instructions provided by Cook’s Illustrated using Easy Off to remove severe rust.
