Our top picks at a glance

A well-seasoned flat-top is the difference between a griddle that glides and one that glues your eggs to the steel. Seasoning is simple: thin oil, baked on, repeated.

The short answer

Wash and dry the steel, heat it, wipe on a very thin coat of high-smoke-point oil, heat until it stops smoking, and repeat three to five times. Thin coats are the secret.

How to season a new griddle

  1. Wash it. Follow your maker's first-use instructions. Many call for warm soapy water on a new griddle to remove factory residue. Rinse and dry thoroughly.
  2. Heat it. Turn the burners on to dry the surface completely.
  3. Oil it thinly. Pour a small amount of high-smoke-point oil, such as canola, vegetable or avocado, onto the surface. Spread it in a very thin, even layer with tongs and a folded cloth or paper towel. Wipe off the excess until it looks almost dry. Thick coats turn sticky and flake.
  4. Heat until it stops smoking. Turn the burners up and let the oil bake on until the smoke fades. The surface will darken.
  5. Repeat three to five times, letting it cool slightly between coats.
  6. Cook something fatty. Bacon or burgers build the seasoning further.

Keeping the seasoning

  • Scrape while it is warm after each cook.
  • Wipe on a thin film of oil before it cools, to protect the steel.
  • Avoid strong soap and long soaks on a seasoned top.
  • Cover it after every use.

Fixing problems

Rust

Scrub with a griddle stone or steel wool, wash, dry and re-season. Prevent a repeat with oil and a cover.

Food sticks

Thin or damaged seasoning, a cold surface or too little oil. Preheat fully and add a thin layer of oil as you cook, or re-season.

Flaking

The coats were too thick. Scrape the flakes off and re-season with thinner coats.

Uneven heat

Wind and blocked burners cause it. Shelter the griddle and clean the burners when cold. Never splash cold water on a hot top, because thermal shock can warp it.

Frequently asked questions

Why do you have to season a griddle?

Seasoning bakes thin layers of oil onto the steel to form a hard, slick, protective coating. It makes the surface non-stick and protects it from rust.

What oil is best for seasoning a griddle?

Any cooking oil with a high smoke point, such as canola, vegetable or avocado oil, works. Many people like flaxseed oil, though thick coats of it can flake. What matters most is applying very thin coats.

How many coats of seasoning do I need?

Three to five thin coats is a common starting point, with each one heated until it stops smoking. Cooking fatty foods like bacon builds more over time.

How do I fix a rusty griddle?

Scrub off the rust with a griddle stone or steel wool, wash and dry the surface, then re-season with several thin coats. Cover the griddle after use to keep rust from coming back.
