How to Season Your Pizza Steel to Make It Last

A pizza steel, also called baking steel, is the single most important investment for a home pizza chef. And with proper care, a pizza steel, will last you a lifetime. One of the keys to making it last is to season the steel, which can be done in a few easy steps.

Do You Need to Season a Pizza Steel?

Yes, just like a cast-iron skillet, your pizza steel should be seasoned to prevent corrosion of the steel and protect it from rusting. Another benefit of seasoning is that it makes the steel more stick-resistant.

Most pizza steels are made from stainless steel, but there are more than 150 grades of stainless steel. And some of these are more prone to rust than others. So even if a type of steel is considered stainless, it doesn’t mean your pizza steel can’t rust, it just means it’s more rust-resistant. With time most pizza steel will rust if not taken proper care of.

If you have some experience with baking on pizza steels, you probably know that pizza doesn’t really stick when you bake at a high enough temperature. However, having a pizza steel that is more stick-resistant is a huge benefit when it comes to cleaning. If you season your pizza steel regularly, it makes cleaning a lot easier.

What Does It Mean to Season a Pizza Steel, and Why Do You Need It?

Seasoning, in the context of cookware, is the process of adding a high smoke point oil, followed by exposing the pizza steel to heat. The goal of seasoning is to prevent corrosion and to add a protective layer that will prevent rust. In addition to making a non-stick surface on the steel that reduces sticking.

To season iron or steel, you apply a thin layer of oil and then expose it to heat for 30 minutes to an hour. What happens when you expose it to heat is polymerization and carbonization of the oil. This process is what creates the protective layer on the surface.

What Do You Need to Season a Pizza Steel?

The only thing you really need to season is a pizza steel oil and an oven to heat the steel in. But you also need the clean it thoroughly before you start the seasoning process.

Cleaning Equipment

To clean a pizza steel, you need a sponge or nylon brush. It can also come in handy to have a dough scraper to remove larger burnt pieces on the surface. For particularly tough spots, steel wool (affiliate link) is also useful. An even better alternative to steel wool is EarthStone Kitchenstone Cleaning Block, which is both easier to use and cleans the steel better and faster.

A High Smoke Point Oil

To season the steel, you need a high smoke point oil. Smoke point refers to the temperature where the oil starts to burn and smoke. And a high smoke point is generally defined as 350°F (175°C) or more. The reason you want a high smoke point oil is that you don’t want the oil to burn when you place the pizza steel in the oven. You also want an oil without too much flavor, as this can give your pizza some odd flavors when you use the steel.

Some good high smoke point oils for seasoning a pizza steel are:

  • Coconut oil
  • Grapeseed, oil
  • Peanut oil
  • Canola oil
  • Sunflower oil

An Oven For Baking The Steel

You also need an oven that can reach 350°F (175°C). But if you own a pizza steel, I assume you already have an oven!

How to Season a Pizza Steel

If you have experience seasoning cast iron, the process is essentially the same for pizza steels. Here’s how to season your pizza steel in 5 easy steps.

1. Clean The Pizza Steel

Before you season the steel, make sure it’s clean and dry.

When you bake pizza at high temperature, excess flour, melted cheese, and sauce tend to burn to the steel. You can use a bench scraper or spatula to get rid of the biggest chunks. Then use a sponge or nylon brush to clean it properly. If that is not enough, you can use steel wool or EarthStone Cleaning Block. 

When you’ve got rid of the worst parts, clean the pizza steel using a sponge or brush and hot water. Never leave the steel soaking in water, as this can lead to rust development.

Using soap on your pizza steel is not recommended because aggressive soap can damage the steel. Even though you can use mild dishwashing soap, you don’t need it, so I generally recommend just sticking to hot water. You should also never clean a pizza steel in the dishwasher, this is both bad for the pizza steel and the dishwasher!

2. Apply a Thin Layer of Oil

When the steel is clean and completely dry, it’s time to add oil. Spread a thin layer of high smoke point oil on the surface of the pizza steel. Then wipe off any access oil using a paper towel. You want the entire surface to have an even, thin layer of oil.

3. Bake the steel in the Oven

Next, place the pizza steel in a cold oven, heat it to 350°F (175°C), and leave it in the oven for 1 hour. This will create a protective surface on your steel.

During baking, the steel can get darker but don’t worry, this is natural. When you use, and especially when you season, your pizza steel, it will get a little darker every time.

4. Cool Completely

When the time is up, leave the pizza steel in the oven to cool completely, before you take it out. Hot steel is extremely dangerous, so be careful!

5. Store the Pizza Steel in a Dyr Place

Store your pizza steel in a dry place, with no moisture. This means don’t store it in a humid basement etc. If the steel is exposed to moisture it can rust.

The most important is to store your pizza steel in a dry place to avoid rust. Another thing to keep in mind is that the weight of the steel can ruin other things, so I like to place it on the very bottom of the drawer under my oven.

I usually store my pizza steel at the very bottom of the drawer under my oven. That should be a pretty dry place, and since I put it in the bottom, there is nothing it can break because of the weight.

Some steels also come with a protective cover, I recommend using that if you have one.

How Often Should You Re-Season a Pizza Steel?

How often you need to re-season your pizza steel depends on how frequently you use it. A general rule of thumb is to re-season every 3-6 months (2-4 times a year).

I use my pizza steel at least once a week, so I re-season mine every 3 months or so.

Do You Need to Season a Pizza Steel the First Time You Use It?

Most pizza steels come pre-seasoned when you buy them. It’s therefore not necessary to season it before you use it for the first time. It does however not do any harm to season it, so if you’re not certain, just go ahead and season your steel before you start using it

  1. Thanks for the helpful guide!

    But: two things…
    You can get cheaper steel wool from almost any grocery or hardware store. Secondly, there are so many typos. The best one is “leave your piss steal in the oven to cool.”

    1. I’m happy to hear that you found it helpful. I’ll fix the typos and improve the article. Thank you for your feedback, I appreciate it!

  2. Got my 16×16 1/2 inch pizza steel in the mail today. It weighs about 50 lbs so cleaning was a task. Good info on how to clean and season. Since the steel thicknesses range from 1/4 to 1/2 inch, does seasoning time differ based on this?

    1. Hi, great question! Seasoning is a treatment of the surface of the steel. Therefore, a thick pizza steel doesn’t require more time than a thin pizza steel.

  3. I have a sheet metal friend. Could I get a 1/4” x 14 x 20 piece of stainless (rounding the edges!) from him, season it, and I’m ready to go? If not, any pizza steel recommendations. Thanks for your info!

  4. What is your week to week maintenance? I bake pizza 1X per week so do I need to scrape the big stuff and wash with hot water every week? Or should I just leave it and season every 90 days or so?

    1. I usually remove as much as possible and clean it with hot water after each use. But if you bake often, and don’t spill anything on the steel, I’m sure you’ll be fine not washing it every single time.

    1. It depends on how bad the rust is, but I would start with steel wool. If that’s not enough, you can try using sandpaper. Then re-season your pizza steel and store it in a dry spot to avoid more rust to develop.

  5. Hello, i seasoned my pizza steel with coconut oil and it smoked like crazy. Had the oven at 350. Will it smoke every time i use it? I’m a little discouraged.

    1. The initial seasoning process can involve the some smoke, particularly if the oil layer is a bit thick. But the smoke problem should get better as you use the steel, and it becomes more seasoned. Ensure good ventilation in your kitchen when seasoning or using the pizza steel the first couple of times.
