A dark, well-seasoned griddle is a thing of beauty. That deep black surface isn’t paint and it isn’t luck. It’s earned through heat, oil and repetition, and it’s the foundation for every great cook that follows.
Skip it, and you’ll feel it right away: food sticks, steel rusts, and cleanup turns into a chore. A seasoned griddle does the opposite. It releases food cleanly, shrugs off moisture and gets better every time you use it.
Seasoning isn’t an extra step. It’s the first real step to owning your griddle.
What Oil to Use When Seasoning a Griddle
The oil you choose matters. You want one that handles high heat and spreads easily, so it can bake onto the steel and form a smooth, protective layer. Good options include:
- Blackstone Griddle Conditioner, a blend made specifically for griddles
- Avocado oil
- Grapeseed oil
- Canola oil
Whatever you choose, the real secret is thin layers. Add a small amount, spread it across the steel, then wipe it back until the surface looks almost dry. Thin coats build that deep, dark finish. Thick coats turn sticky and can flake.
Why Seasoning Your Griddle Matters
Seasoning does three big jobs:
- It creates a natural non-stick surface. When oil is heated past its smoke point, it bonds to the steel through a process called polymerization. The result is a slick, durable layer that food doesn’t want to stick to.
- It protects against rust. Bare steel and moisture don’t mix. Seasoning seals the surface so water and oxygen can’t get to the metal.
- It makes you a better cook. A seasoned griddle holds heat evenly, sears cleaner and builds a better crust on burgers, steaks and veggies.
Think of it like breaking in a cast iron pan or a good pair of leather boots. The first round matters, the next few matter even more, and over time the surface becomes better than new. Treat your griddle right from day one and it can last for years.
How Often to Season a Griddle
Good news: you don’t need to fully season your griddle every time you cook.
A full seasoning is only needed when the griddle is brand new, after you’ve removed rust (here’s how to get rust off a Blackstone griddle), or anytime the protective layer has been stripped away. You’ll usually know because the surface starts looking gray, patchy or dull, or food begins to stick more than usual.
If your griddle still looks dark, feels smooth and cooks well, you don’t need to start over. Just clean it, dry it completely and wipe on a very light coat of oil before storing it. Most of the time, protecting the seasoning you already have matters more than rebuilding it.

If your Blackstone is brand new, wash the cooktop once with a little dish soap and warm water to remove factory oils, dust and manufacturing residue. Rinse off every bit of soap and dry the surface completely before adding any oil. After that first wash, skip the soap. From then on, the goal is to protect your seasoning, not strip it away.
How to Season a Blackstone Griddle (Step by Step)
1. Start With a Clean, Bare Surface
A new griddle may still have a light factory coating, and a used one may have dust or leftover residue. Give the cooktop a quick clean with warm water and a gentle scrub, then dry it completely. Clean, dry steel gives the seasoning the best possible surface to bond to.
2. Heat the Griddle Until It’s Hot
Turn all the burners on high and let the griddle heat for 10 to 15 minutes. You’ll see heat rising off the surface, and the steel may start to change color. That’s exactly what you want. Seasoning happens when heat and oil work together.
3. Apply a Very Thin Layer of Oil
Once the griddle is hot, pour a small amount of oil onto the surface. A couple of tablespoons is plenty for a 36” griddle, and less for smaller sizes. Don’t worry about coverage yet. Just get a little oil on the steel.
4. Spread It Thin and Let It Smoke Off
Grip a folded paper towel or lint-free cloth with tongs and spread the oil across the entire cooktop, working it into the corners, edges and sides. Then wipe it once more to thin it out. It should look almost dry. If the griddle looks wet or shiny, there’s too much oil.
Leave the burners on high and let the oil smoke off. When the smoke stops, usually after 15 to 30 minutes, the oil has bonded to the steel and your first layer of seasoning is done.
5. Repeat to Build the Seasoning
Great griddles are built layer by layer. Add another small amount of oil, spread it thin, and let it smoke off just like before. Repeat 3 to 5 times. With each round, the steel gets darker and the surface gets stronger.
When the cooktop has an even, deep black finish with a slight sheen, it’s ready. From here, every meal you cook adds to that surface, and your griddle keeps getting better with time.
Safety first: always season outdoors, wear heat-resistant gloves, keep paper towels away from open flames and never leave a hot griddle unattended. Keep a fire extinguisher or baking soda within reach, and never put water on a grease fire.
A Simple Way to Protect Your Seasoning and Keep Your Griddle Rust-Free
Once you’ve built great seasoning, the biggest threat to it is moisture. Humidity, condensation under the lid and changing weather slowly wear down even a well-built layer, and once water sits on steel long enough, rust starts to creep in.
A light coat of oil after every cook helps. But one extra step makes a real difference: covering the cooking surface itself.
An OZG silicone griddle cover lays flat directly on your cooktop and creates a barrier between your seasoning and the outside world. It helps block moisture, dust, pollen and pests from settling on your griddle between cooks, so you can:
- Preserve the seasoning you just worked to build
- Reduce the chance of rust forming over time
- Keep your cooktop clean and ready to use
- Re-season less often
Just let the griddle cool completely before you lay the mat on. If you’re taking the time to season your Blackstone properly, it makes sense to protect it afterward.

What You’ll Need
Seasoning a Blackstone doesn’t take a garage full of gear. These basics make it easy:
- Griddle conditioner or a high-heat oil. See the recommended oils above.
- Paper towels or lint-free cloths. For spreading oil into very thin layers. Thin is everything.
- Tongs or heat-resistant gloves. The surface gets extremely hot, so keep your hands safe.
- A scraper or griddle spatula. To clear off residue or old buildup before you start.
- A squeeze bottle of water. For steam-cleaning your griddle after you cook. (It’s not for fires: never use water on a grease fire.)
