How to season a Blackstone griddle

First: which plate do you have?

This is the step most guides skip, and it is why people conclude their new griddle is defective.

Original models use bare rolled carbon steel — 10-gauge on the 28. This is the classic flat-top surface and it is what essentially all online seasoning advice describes.

Omnivore models use a different plate. It is not a non-stick coating, but it is not bare rolled steel either, and it takes seasoning differently — the surface darkens at a different rate and the early rounds look different. The two plates compared.

Follow Blackstone’s own guidance for whichever plate you have, and treat generic carbon-steel advice as applying fully to the Original and approximately to the Omnivore.

The Blackstone first seasoning

1. Wash once with warm soapy water to remove manufacturing residue, rinse, and dry completely and immediately. Bare steel starts to rust within minutes if left wet.
2. Heat all burners on high until the plate darkens slightly, ten to fifteen minutes. Blackstone’s larger plates take longer at the edges than the center.
3. Apply oil very thinly — a squeeze bottle makes this far easier — and wipe it back until the surface looks almost dry. Include the edges, the sides and the corners, which is where rust starts.
4. Heat until the smoking stops. Fifteen to twenty minutes per round.
5. Repeat three to five times.
6. Cook bacon.

The general process with the full mistake list.

Blackstone-specific notes

The rear grease channel

Blackstone’s rear grease management means oil runs to the back. During seasoning, oil that pools in the channel will not polymerize properly — it just sits there and gets gummy.

Wipe the channel between rounds rather than letting it collect.

Edge coverage on the big plates

On a 36″ the burners do not reach the outer edges as effectively as the center. Those edges are where rust starts, so they need the same seasoning attention even though they heat more slowly.

A couple of extra minutes per round, and deliberately oiling right to and over the edge, pays for itself.

If it came pre-seasoned

Some Blackstone configurations ship with a factory seasoning. Follow the included guidance — usually a wipe and a heat cycle — rather than running the full process, which would just add thick layers on top.

Keeping it seasoned

After each cook: scrape while hot, squirt water to steam-lift residue, scrape again, wipe, and lay a very thin oil film on while the plate is still warm. Then cover it once cool.

On bare Blackstone steel the cover is not optional. The plate will rust within weeks of neglect in a wet season, which is the single most common way these griddles are ruined. Rust prevention.

If it has already gone wrong

The good news about bare carbon steel is that it is completely recoverable. Rust comes off and the plate re-seasons. Flaking seasoning can be taken back to a sound layer and rebuilt. Nothing about a steel top is permanent except warping.
