Ways to clean a cast iron skillet after cooking
Here’s how I clean my cast iron pan after cooking… in 4 steps:
- 1) Allow it to cool (never put cold water in hot pan for risk of thermal shock)
- 2) Cover the crusty bits stuck to the pan with water and let sit for 15 mins or thereabouts
- 3) Scrub with warm water, mild detergent, and a stiff nylon brush and scraper
- 4) Dry well
An optional method:
- 1) Let cool
- 2) Add teaspoon of salt and teaspoon of oil and scrub with a paper towel
- 3) Wipe away and then rinse in hot water
- 4) Dry well
Options for the excess fat left in the pan: Before the pan cools, drain the excess fat or oil into a container for later use in a recipe or let the pan cool with the fat hardening and then remove it using a paper towel. By not pouring it down the sink you won’t contribute to ‘fatbergs‘, which block sewers.
Alternatives: If you don’t have salt on hand, use sugar, or try coffee grounds mixed with oil. If you don’t have oil to spare try a little water to make a paste.
