How to Season and Maintain an Outdoor Griddle

The cooking surface you start with is not the cooking surface you end up with. That raw, silver-grey steel that comes out of the box is a blank canvas. What you build on top of it, whether through seasoning, through regular cooking, through proper care becomes something else entirely. 

Darker. Slicker. More responsive. A surface that releases food cleanly, develops flavor, and gets measurably better every time you cook on it.

That transformation doesn't happen automatically. It happens because you know how to season an outdoor griddle properly...  and then keep it that way.

Get this right from the start and you'll have a cooking surface that rewards you for years. Skip it, or do it halfway, and you'll be fighting rust, sticking food, and uneven cooking for as long as you own the grill.

This is the complete guide. Start here.

Seasoning isn't a coating you apply once and forget. It's a process of building up thin layers of polymerized oil directly into the steel, which creates layers that bond to the surface, protect it from rust, and create a naturally non-stick cooking finish that improves with every cook.

When oil is applied to a hot steel surface and heated past its smoke point, it undergoes a chemical transformation. The oil oxidizes and polymerizes which means its molecules bond together and to the metal in a way that can't be wiped off. Each layer adds depth, protection, and performance to the surface beneath it.

This is why a well-seasoned griddle feels and cooks completely differently from a new one. The surface isn't just cleaner, it's has undergone a chemically different transformation. And that difference accumulates over time in a way that no factory coating can replicate.

It's also why a poorly maintained griddle deteriorates. Without those protective polymerized layers, bare steel oxidizes. Rust forms. Food sticks. The whole experience suffers.

Seasoning a griddle requires very little. What it does require, it requires specifically.

Oil with a high smoke point. This is non-negotiable. Flaxseed oil, grapeseed oil, avocado oil, or Crisco shortening all work well. Standard olive oil does not because its smoke point is too low, it burns rather than polymerizes, and it leaves a sticky residue rather than a hard seasoning layer. Use the right oil and the process works. Use the wrong one and you're starting over.

Paper towels or a lint-free cloth. For applying oil in thin, even layers. Thin is the operative word, more on this shortly.

Heat-resistant tongs or a scraper handle. For moving the paper towel across a hot surface safely.

Time. The first seasoning session takes 45–60 minutes. It's not active work, it's mostly waiting between the building layers, but it can't be rushed.

This is the foundation. Everything else builds on how well you do this first session of seasoning your outdoor griddle.

New griddles come with a protective coating from the factory. This is usually oil or wax applied to prevent rust during shipping and storage. It needs to come off before seasoning begins.

Turn all burners to high and let the griddle heat for 10–15 minutes. You'll see the surface change colo, darker patches appearing, possibly some smoke. That's the factory coating burning off. Let it go until the smoking stops and the surface looks dull and slightly discolored across most of the cooking area. 

Turn off the heat and let the griddle cool to the point where it's hot but touchable, usually around 300–350°F if you're using an infrared thermometer.

With a paper towel held in tongs, apply a thin, genuinely thin, layer of your chosen oil across the entire cooking surface. Edges included. Every part of the steel that will ever contact food or moisture needs to be covered.

Thin is critical here. A thick layer of oil will not polymerize properly, rather it pools, it smokes excessively, and it leaves a sticky, uneven finish rather than a hard seasoning layer. If you can see oil sitting on the surface, you've applied too much. Wipe it back until the surface looks almost dry with just a slight sheen.

Turn all burners back to high. The oil will start smoking almost immediately; this is the polymerization process happening. Let it run until the smoking stops completely. This takes around 10–15 minutes. The surface will darken slightly with each layer. That darkening is exactly what you want.

Let the surface cool slightly, apply another thin layer, heat until the smoke stops. Repeat this process four to five times for the first seasoning session.

By the end, the surface should have shifted from silver-grey to a warm golden-brown or light amber. It won't be the deep black of a well-used griddle yet because that will come over time with more cooking and use. But the foundation is built.

After the previous layer, apply one final thin coat of oil and let the griddle cool completely with the burners off. This last layer protects the seasoning you've built during the cool-down and sets it for first use.

Seasoning the griddle once is the starting point. Maintaining it after every cook is what builds the surface over time and keeps it performing.

The routine takes five minutes. If you stay on top of it each time the griddle will looks after itself. Missed maintanence puts your griddles wear at risk.

Catching the griddle while it is still hot is the window. Cleaning a hot griddle is dramatically easier than cleaning a cold one because the residue lifts off hot steel with minimal effort.

Use a metal scraper to push food debris, grease, and any stuck bits toward the grease channel and into the collection tray. Work from the back of the surface toward the front, or toward the sides depending on your griddle's drainage direction.

For anything that's stuck more firmly, add a small amount of water to the hot surface. It will steam aggressively and that's perfectly normal. The steam loosens stuck residue and makes it easy to scrape clean. Work quickly while the surface is still hot enough to steam.

Once the surface is scraped clean, wipe it down with a paper towel to remove any remaining moisture or debris. Then apply a thin layer of oil (the same high-smoke-point oil you used for seasoning) across the entire surface while it's still warm.

This step does two things: it protects the steel from moisture and oxidation during storage, and it adds a micro-layer of seasoning to the surface every single time you cook. Over dozens of sessions, those micro-layers accumulate into the deep, dark, naturally non-stick surface that makes a well-used griddle one of the best cooking surfaces you'll ever own.

Let the griddle cool completely before covering it.

Even a brief rain shower on an uncovered, unsealed griddle can start mild surface rust. A fitted cover keeps moisture, debris, and UV exposure off the surface between cooks. If your griddle didn't come with one, get one here. It's one of the best maintenance decisions you'll make.

Rust on a griddle is not necessarily a death sentence. It's more of a maintenance problem, and it's fixable. Most surface rust on a cold-rolled steel griddle can be removed and the surface restored without drama, provided you catch it early.

Light surface rust, the orange patches that develop on the cooking surface, usually from moisture exposure, responds well to a coarse griddle stone or steel wool. Heat the griddle to medium, apply a small amount of oil, and scrub the rusted area in circular motions with the griddle stone until the rust is gone. The surface will look raw and dull again in that area. That's fine, you can season it back up with two or three rounds of oil and heat immediately.

Deeper rust that has pitted the surface requires a more aggressive treatment, typically a thorough wire brush session, cleaning with warm soapy water (one of the only times soap is appropriate on a griddle), and a full re-seasoning from scratch across the affected area.

This situation is preventable. A cover, a post-cook oil layer, and basic attention to moisture exposure means it should never happen.

Rust on the cooking surface is recoverable. Rust that has eaten through the steel, warped the surface, or compromised the structural integrity of the griddle body is a different problem and a sign that the build quality wasn't up to the task of living outdoors in the first place.

This is one of the reasons the Elite Griddle Series uses heavy-gauge steel construction throughout. The cooking surface, frame, and hardware are all built for the outdoor environment, not just for how the griddle looks in the first season.

Regular post-cook maintenance handles the day-to-day. A deeper clean two or three times a season keeps the griddle in top condition and addresses the buildup that routine scraping doesn't catch.

Heat the griddle to medium-high. Use a griddle scraper to work the entire surface methodically, pushing all residue toward the grease channel. Add water in small amounts as needed to steam off stubborn buildup.

Once the surface is clean, apply oil and wipe down thoroughly. Check the grease trap and empty it if needed. A full grease trap is a fire hazard and something that sneaks up on you during busy cooking seasons.

Inspect the burner tubes for blockages, spider nests, or grease buildup that could affect performance or create a hazard. A wire brush through the burner tubes once a season is cheap insurance against ignition problems.

Check the side shelves, cart connections, and any moving parts. Tighten anything that's worked loose. Apply a small amount of food-safe lubricant to any pivot points or hinges that are stiffening up.

If the griddle is going into storage for winter or an extended period, do a full deep clean, reseason the surface with two to three rounds of oil and heat, apply a final protective oil coat, and cover it. If possible, store it somewhere that doesn't see direct moisture exposure, either a garage or covered patio rather than open to the elements.

A griddle that goes into winter storage clean and well-oiled comes out in spring ready to cook. One that goes in dirty and dry comes out with problems.

A well-seasoned, properly maintained outdoor griddle is one of the best long-term investments in a backyard kitchen. The surface that comes out the other side of six months of regular cooking will be dark, slick, responsive and cooks better than the day you bought it. Better than any non-stick pan. Better than anything you could buy off a shelf.

That's the result of every cook, every layer, every five-minute post-session routine adding up into something genuinely exceptional.

The Elite Griddle Series gives you the right surface to start with which is a heavy cold-rolled steel built to season properly and last for years. The rest is up to how you use it.
