How to Season a Cast Iron Skillet: Complete Guide

Quick take: Seasoning creates a naturally non-stick, rust-resistant coating on cast iron. The process involves applying oil and heating it until it polymerizes into a hard, protective layer.

A well-seasoned cast iron skillet is a kitchen treasure that improves with age. To season a new skillet or restore a neglected one, start by cleaning it thoroughly with hot water and a stiff brush.

Apply a thin, even layer of high-smoke-point oil (flaxseed, grapeseed, or vegetable oil) to every surface. Place the skillet upside-down in a 450°F oven for one hour, with a baking sheet below to catch drips.

Let it cool completely in the oven. Repeat 3-4 times for a new skillet to build a strong base layer.

Maintenance tips: Clean promptly after use while still warm, use hot water only, and dry immediately. Apply a light oil coating after each use. Never soak or put in the dishwasher.

Frequently Asked Questions

What oil is best for seasoning cast iron?

High-smoke-point oils like flaxseed, grapeseed, or vegetable oil work best. Apply a thin, even layer and heat at 450°F for one hour.

How often should you season cast iron?

Full re-seasoning is only needed when the coating is damaged. Regular maintenance involves cleaning promptly after use, drying immediately, and applying a light oil coating after each use.

Can you wash cast iron with soap?

Modern dish soap is fine for occasional use, but hot water and a stiff brush is preferred for daily cleaning. Never soak cast iron or put it in the dishwasher.
