You just got a new electric grill. Or your old grill plate has started sticking more than it should. Either way, seasoning the plate is the answer.
Most people skip this step. They pull the grill out of the box, plug it in, and start cooking. Then they wonder why food sticks, why the surface looks patchy, and why it is so hard to clean afterward.
Seasoning solves all of this.
I have seasoned cast iron griddles, teppanyaki grill plates, smokeless grill surfaces, electric BBQ grill grates, and commercial electric countertop griddle surfaces over many years. The process is simple. It takes less than thirty minutes the first time. And once you understand why it works, you will never skip it again.
This guide covers everything. How to season a new plate. How to re-season an old one. Which oils work best. And how to maintain the seasoning so it lasts for years.
Let us get into it.
What Is Seasoning and Why Does It Matter?
Seasoning is the process of baking a thin layer of oil onto a cooking surface at high heat.
When oil reaches its smoke point and is held there on a metal surface, it undergoes a chemical change called polymerization. The oil molecules bond together and bond to the metal surface. They form a hard, smooth, non-stick coating that is baked into the material rather than sitting on top of it.
This is completely different from a spray-on non-stick coating. Seasoning builds up gradually over time. Each layer adds to the one beneath it. A well-seasoned surface improves with every cook.
Here is what seasoning does for your grill plate:
Prevents sticking. The polymerized oil layer creates a slick surface that food releases from easily. This means perfect grill marks, clean flipping, and no tearing.
Protects against rust. A bare metal surface oxidizes. Moisture in the air reacts with the metal and causes rust spots. A seasoned surface seals the metal and prevents this reaction.
Builds flavor over time. A well-seasoned surface accumulates layers of cooked-in flavor. Each session adds a tiny amount of complexity to the base layer. Experienced cooks treat their seasoned surfaces as something to develop and protect.
Makes cleaning easier. A properly seasoned surface wipes clean in seconds. Food does not bond to the surface the way it does on bare or poorly maintained metal.
Which Electric Grill Plates Need Seasoning?
Not every grill plate needs seasoning. Here is how to tell which type you have.
Cast iron grill plates and cast iron griddle surfaces Always need seasoning. Cast iron is porous and rusts without a seasoning layer. This applies to cast iron griddle plates in electric BBQ grills, standalone cast iron countertop griddle units, and cast iron grates on any electric grill model.
Stainless steel plates Benefit from light seasoning. Stainless steel does not rust but it can stick without a seasoning layer. A thin layer of oil seasoned into the surface significantly improves the cooking and cleaning experience on any stainless steel electric grill plate.
Carbon steel plates Always need seasoning. Similar to cast iron in behavior and requirements. Teppanyaki grill plates are commonly made from carbon steel and require thorough initial seasoning.
Non-stick coated plates Do not need seasoning. Do not apply seasoning to a PTFE or ceramic non-stick coated plate. The coating already provides the non-stick layer. Adding oil and heating it may damage the coating.
If you are unsure what your plate is made from, check the manual. The Decakila, Ninja Sizzle, and other popular brands specify the plate material in their documentation.
What Oil to Use for Seasoning
Oil choice matters.
You need an oil with a high smoke point. Low smoke point oils burn and produce sticky, gummy residue rather than a clean polymerized layer.
Best oils for seasoning electric grill plates:
- Flaxseed oil Extremely high smoke point. Produces the hardest, most durable seasoning layer of any oil. The top choice of many experienced cast iron users.
- Avocado oil Very high smoke point at around 270°C. Widely available. Easy to work with. My personal daily choice for seasoning.
- Refined coconut oil High smoke point. Solid at room temperature which makes application easy. Produces a good seasoning layer.
- Vegetable shortening Traditional choice for cast iron seasoning. Works well and is inexpensive.
- Refined vegetable oil Accessible and effective for basic seasoning. Widely available and inexpensive.
Oils to avoid:
- Extra virgin olive oil Smoke point too low. Leaves a gummy residue.
- Unrefined coconut oil Same problem. Smoke point too low.
- Butter or any dairy fat Burns too quickly and leaves residue.
- Spray-on cooking sprays Many contain additives that build up as sticky residue rather than clean seasoning.
How to Season a New Electric Grill Plate: Step by Step
Follow these steps when you first get a new grill or after stripping an old plate back to bare metal.
Step 1 – Wash the Plate First
New grill plates often have a light factory coating or protective oil applied during manufacturing. Wash this off completely before seasoning.
Use warm soapy water and a soft cloth or sponge. Scrub the entire cooking surface including the edges and any raised ridges. Rinse thoroughly. Dry immediately with a clean cloth.
For cast iron and carbon steel, do not leave any moisture on the surface. Dry with a cloth immediately after rinsing, then place on the grill or over a heat source for two to three minutes to evaporate any remaining moisture.
For a Ninja Sizzle or similar model with removable plates, wash the plates in the sink with warm soapy water. Dry completely before proceeding.
Step 2 – Apply a Thin Layer of Oil
Apply a very small amount of your chosen oil to a clean paper towel or cloth. Wipe it all over the cooking surface. Cover every area including edges and corners.
Then take a fresh dry paper towel and wipe the surface again. You want to remove almost all the oil. The layer should look nearly invisible. If it looks wet or shiny with oil, you have applied too much.
This is the single most common mistake in seasoning. Too much oil produces a thick, sticky, uneven layer that does not bond properly. Thin layers bond cleanly and build up consistently over multiple rounds.
Step 3 – Heat the Plate
For removable plates that can go in an oven:
- Place the oiled plate face-down on an oven rack
- Set the oven to 230°C to 260°C
- Bake for one hour
- Turn off the oven and leave the plate inside to cool completely
For plates fixed to an electric BBQ grill or countertop griddle:
- Turn the grill to maximum heat
- Let it heat for twenty to twenty-five minutes
- The oil will smoke briefly and then stop
- Turn off the grill and let it cool completely
For a teppanyaki grill or commercial electric griddle that cannot go in an oven:
- Turn the hot plate to its highest setting
- Apply the thin oil layer with a cloth held in tongs
- Let the oil smoke and polymerize for fifteen to twenty minutes
- Turn off and cool completely
Step 4 – Repeat the Process
One round of seasoning is a start. It is not enough on its own.
For new cast iron griddle and carbon steel plates, repeat the seasoning process three to four times before cooking on the surface for the first time. Each round builds another bonded layer. Three rounds produce a noticeably smoother, more non-stick surface than a single round.
Apply oil, heat until smoking stops, cool, apply oil again, heat again. This is all there is to it. The process is simple but repetition is what builds the result.
How to Re-Season an Old Electric Grill Plate
If your existing grill plate has developed sticky patches, rust spots, or uneven coating, re-seasoning restores it completely.
Step 1 – Strip the Old Seasoning
You need to start from bare metal.
For cast iron and carbon steel: Scrub the surface with coarse salt and a stiff brush. If the surface has rust, use fine steel wool or a chain mail scrubber to remove all rust and old seasoning. Wash with warm soapy water. Rinse and dry immediately.
For stainless steel plates: Clean thoroughly with warm soapy water and a non-scratch abrasive pad. Remove all grease and residue. Rinse and dry.
For teppanyaki grill and commercial electric surfaces: Heat the surface first to loosen residue. Scrape clean with a metal spatula or flat scraper while hot. Allow to cool. Then wash with soapy water and rinse.
Step 2 – Dry Completely
This step is critical for cast iron and carbon steel. Any remaining moisture causes rust before the seasoning layer can protect the metal.
After washing, dry with a cloth. Then heat the plate on the grill or in the oven at low heat for five minutes to evaporate all remaining moisture. Only apply oil once the surface is completely dry and warm.
Step 3 – Follow the Same Seasoning Process
Apply a thin oil layer and heat as described in the new plate steps above. Repeat three to four times for the best result.
Maintaining the Seasoning Long-Term
Seasoning is not a one-time task. It builds up and improves with every cook when you maintain it properly.
After every cooking session:
- Clean the plate while still warm with a cloth or paper towel
- For stubborn residue, use a small amount of coarse salt as a gentle abrasive
- Rinse briefly if needed cast iron can tolerate a quick rinse with plain water but avoid soaking
- Dry immediately and completely
- Apply the thinnest possible layer of oil before storing
- That thin oil layer protects the surface until next time
What damages seasoning:
- Soaking in water breaks down the bonded layers
- Harsh dish soap strips the seasoning, particularly on cast iron
- Metal scourers or steel wool after seasoning is established scratches and removes layers
- Cooking very acidic foods like tomato sauces for long periods acid degrades the seasoning layer
What builds seasoning:
- Regular cooking with oil
- Cooking fatty foods
- Light re-oiling after every clean
- Occasional full re-seasoning rounds every few months
Seasoning Tips for Specific Grill Types
Teppanyaki grill plates: Carbon steel teppanyaki surfaces need thorough initial seasoning of four to five rounds. Once established, the seasoning builds quickly with regular cooking. Re-season any time the surface looks dull or food starts sticking.
Decakila electric grill plates: Decakila commercial electric and home grill models often use carbon steel or stainless steel plates. Check the material specification before choosing your seasoning method. Carbon steel models need full cast iron-style seasoning. Stainless models benefit from light seasoning.
Smokeless grill surfaces: Many smokeless grill models use non-stick coated plates that do not require seasoning. Check before applying oil. For models with cast iron or steel plates, follow the full seasoning process.
Countertop griddle surfaces: A flat countertop griddle whether an electric BBQ grill-style unit or a standalone hot plate benefits significantly from proper seasoning. The large flat surface area makes even oil application easy. Season in the same way as a teppanyaki grill.
Top grill plates with ridges: Pay extra attention to the ridges during seasoning. Oil tends to pool in the valleys between ridges. Use a brush or folded cloth to apply oil evenly to the ridge surfaces where food contacts the plate.
