Cast-iron cookware is heavy, durable and lasts for many decades with the proper care. Some cast-iron skillets come pre-seasoned and only require rinsing with hot water and a thorough drying before using. Others need to be seasoned first to ensure foods don't stick to the surface. If your skillet has become rusty, turned dull gray or has food stuck to it, it will require re-seasoning. The methods are the same for new or old cast-iron cookware.

Things You'll Need

  • Liquid dishwashing soap
  • Dish cloth
  • Absorbent towel
  • Aluminum foil
  • Solid vegetable shortening or cooking oil
  • Timer
  • Stiff nylon scrub brush or a plastic scraper (optional)
  • Paper towel (optional)

Video of the Day

Wash the cast-iron skillet with warm, soapy water and a dish cloth. Rinse well and dry with an absorbent towel.

Place a sheet of aluminum foil on the bottom rack of your oven to catch any oil drips while seasoning.

Coat the interior and exterior of your skillet with a thin layer of solid vegetable shortening. You may use cooking oil if you prefer.

Set the oven to 350 degrees Fahrenheit.

Lay the cast-iron skillet upside down on the top rack of your oven and shut the oven door.

Set a timer for an hour, then turn the oven off. Leave the skillet inside until it sufficiently cools. The skillet is ready to prepare foods.
