Seasoning a stainless steel griddle is optional for rust protection, but a light oil coating improves nonstick performance and builds flavor.
Most stainless steel griddles arrive ready to cook, but a light seasoning layer makes eggs slide and adds a patina that deepens with use. Here is the method, the oil to choose, and the mistakes to skip.
Do Stainless Steel Griddles Need Seasoning?
Manufacturers answer this differently, which is why opinions vary. Napoleon states seasoning is optional and “not essential for corrosion resistant stainless steel,” while other brands say a thin oil layer improves cooking performance even though the surface resists rust without it.
The honest read: the steel will not rust like cast iron, so seasoning is a performance choice, not a protective one. A seasoned stainless griddle gives you a slicker cooking surface, easier cleanup, and that dark patina many cooks associate with a well-used griddle. Skip it and the griddle still works—you will just use more oil and scrub harder after cooking.
The Seasoning Process, Step By Step
You can season any stainless steel griddle with this sequence derived from Napoleon’s and Blackstone’s official guidance.
- Clean and dry the griddle. Wash with soap and water, then dry it completely. Every drop of water must be gone before oil touches the surface.
- Apply a thin oil coat. Put a small amount of high-smoke-point oil on a paper towel or cloth, then wipe it across the cooking surface using tongs. You want a sheen, not a puddle. The thinner the coat, the tougher the seasoning layer.
- That smoke is the oil polymerizing into a hard, nonstick layer.
- Cool and wipe off excess. Turn off the heat, let the griddle cool, then wipe away any remaining oil with a clean cloth.
That’s it. You’ll know it worked when the surface looks slightly darker and slick, and a water drop beads up instead of spreading.
What Oil Should You Use?
The oil you choose determines how well the seasoning bonds. Oils with high smoke points polymerize cleanly, while low-smoke-point oils leave sticky residue. The sources name four oils that work well: grapeseed, avocado, canola, and vegetable oil.
Blackstone sells its own Griddle Seasoning and Cast Iron Conditioner, but it’s not required—any of the oils above does the job.
| Oil | Smoke Point | Notes |
|---|---|---|
| Avocado oil | ~520°F | Highest smoke point, neutral flavor |
| Grapeseed oil | ~420°F | Popular griddle choice, light texture |
| Canola oil | ~400°F | Cheap and widely available |
| Vegetable oil | ~400°F | Budget-friendly, fine for seasoning |
| Crisco | ~360°F | Napoleon’s recommendation for grills |
One rule applies to every oil: thin coat, always. A thick layer never bonds properly and turns into sticky, rancid gunk. If you’re in the market for a new cooking surface, our tested roundup of the best baking steel griddles covers the top models we’ve actually cooked on.
Common Mistakes To Avoid
Seasoning stainless steel is simple, but three errors trip up most first-timers.
Using too much oil. Every manufacturer source repeats the same warning: a thick layer won’t polymerize. It stays wet, attracts dust, and turns rancid.
Ignoring the smoke signal. If you see this, scrub the surface and apply a fresh thin layer.
Seasoning the bottom. Direct grill heat will burn oil off the underside and create smoke. Season only the cooking surface, never the exterior.
Cleaning matters too. Blackstone’s guidance says to scrub in the direction of the grain and use the mildest cleaning method first—soap and water before anything abrasive. This preserves the seasoning layer you built. Stick to food-grade oils only.
