How to Season a Double Burner Griddle | First Cook Is Flawless

Skip this step and your first pancakes become a scraping exercise. A properly seasoned cooking surface turns rust-prone steel into a slick, dark patina that releases food and shrugs off moisture. You can finish the job with vegetable oil from your pantry, no specialty product required, though a dedicated conditioner makes the process more straightforward.

Why Seasoning Matters

Seasoning is the chemical process of bonding oil to the steel with heat. Beyond making eggs slide, that polymerized layer is your griddle’s rust protection. Bare steel rusts within hours in humid air; a seasoned surface does not. The payoff is a griddle that gets better with every cook.

Step-By-Step Seasoning Process

Getting the initial seasoning right comes down to heat, a whisper-thin oil coat, and patience.

1. Clean the plate. Wash the cooking surface with soap and water to remove the factory protective coating and any debris from shipping. Rinse thoroughly.
2. Dry it completely. Towel it dry, then heat it briefly on low to evaporate any trapped moisture. Any water left behind turns to steam and interferes with oil bonding.
3. Turn the heat to high. This preheats the steel so the oil polymerizes instead of pooling.
4. Apply a thin oil layer. Pour a small amount of oil onto a paper towel or cloth held with tongs—never your bare hand—and wipe it evenly across the cooking surface and up the walls.
5. Let it smoke. Keep the heat on high until the oil stops smoking, roughly 15 minutes. The smoke means the oil is bonding to the steel.
6. Repeat. Turn off the heat, let the griddle cool slightly, and repeat steps 4 and 5.

You will know the seasoning is complete when the surface turns dark and slick, and the smoking stops more quickly with each pass. A properly done layer leaves the griddle looking black and shiny, not sticky. If the layer turns chalky or gray, that is carbonizing—a sign you used too much oil or too little heat. Let it cool, scrape it down, and apply another thin layer.

Common Mistakes That Ruin a Seasoning Job

Most seasoning failures trace back to the same handful of errors. The first is applying too much oil and leaving puddles, which creates a sticky, uneven finish. A thin, even coat that just barely wets the surface is the goal. The second is starting before the griddle is fully dry. Moisture blocks the oil from bonding properly.

Another frequent miss is seasoning only the center of the plate while ignoring the edges and corners, which tend to heat less and therefore take longer to cure. Uneven coverage there slows the whole process. Finally, many people stop after one or two coats and wonder why the surface lifts during the first cook.

Practical Tips and Oil Choices

• Use tongs for the oil wipe. Hot steel plus a thin cloth is a burn risk. Blackstone says to hold towels or cloths with tongs and to dispose of oiled paper towels carefully—they can ignite in a trash can.
• Any high-smoke-point oil works. Blackstone allows other cooking oil if its conditioner is unavailable. Vegetable, canola, or grapeseed oil all work well.
• Safety first. Before cleaning your griddle, turn off the knobs and disconnect the propane, then reconnect and follow the ignition steps in your owner’s manual before reheating.
• Skip the specialty cleaner. When you finish seasoning, that’s it. After cooking, scrape and wipe while warm—soap is only for the initial factory-coating wash.

Blackstone sells a purpose-made Griddle Seasoning & Cast Iron Conditioner in 15.3-ounce and 2-pack sizes, formulated specifically for griddle tops and cast iron cookware. If you’d rather use what’s in your pantry, vegetable oil gets the job done identically.

Once the seasoning sets, the griddle becomes a genuinely low-maintenance workhorse. If you are still deciding which double burner griddle to buy, our tested roundup of the best double burner griddles compares the top models by heat output and cooking area.
