How to Season a Blackstone Griddle

Before you cook anything, that new griddle needs a bath. Mix warm water with a little dish soap, grab a cloth, and scrub the whole top. This is the only time soap touches the surface, since it strips off the protective coating the factory sprayed on for shipping. Rinse it, dry it fully with a towel, and check that the steel feels clean. Any leftover coating will smell off when you fire it up, so take your time here.

Hook the propane hose up to the tank and hand-tighten the fitting until it is snug. Open the tank valve all the way, then turn each burner knob to high and hit the igniter. You want the whole flat top screaming hot, because heat is what bonds the oil to the steel. Give it ten to fifteen minutes and watch for the surface to change color as it heats up. That color shift tells you it is ready for the first coat of oil.

Pour a small amount of high-smoke-point oil onto the hot surface. Avocado, flaxseed, and canola all work because they can take the heat without going gummy. Bunch up a paper towel, grip it with tongs so you do not burn your hand, and push the oil edge to edge. You want the thinnest film possible. Too much oil pools and turns sticky instead of hard. If it looks wet, wipe more off.

Now step back and let the heat work. The oil will start smoking hard, and that is exactly what you want. As it smokes, the surface shifts from silver to bronze to brown. Do not touch it or wipe it while it smokes. Wait until the smoke dies down and the color has set, which usually takes a few minutes. That first dark layer is the foundation for everything that follows.

One coat is not enough. Add another thin layer of oil, spread it out, and let it smoke and set again. Do this three or four more times. Each round deepens the color and stacks another layer of protection onto the steel. By the last coat the surface should look dark and even, with a faint sheen. This is where patience pays off, because the layers you build now are what make the griddle nonstick later.

After you cook, scrape the cooled-down surface with a metal scraper to clear off bits and grease. Wipe it with a damp towel if you need to, then dry it right away so it does not flash-rust. Finish with a very thin coat of oil to seal the surface until next time. This quick routine keeps the seasoning you just built and stops rust from ever getting a foothold.

Here is the payoff. The top is a smooth, dark surface with a glossy finish, and it is ready to cook on. Eggs, pancakes, and burgers will release cleanly instead of sticking. The seasoning only gets better the more you use it, so cook often. Keep up the wipe-and-oil habit after every session and this flat top will stay in great shape for years.
