Pizza Steel Temperature: Your Oven’s Max Setting Is Solving the Wrong Problem

By Zach Miller · That Pizza Kitchen

Every pizza steel guide opens the same way: set the oven as high as it goes, wait an hour, launch. I’ve said it too. My own stone vs. steel comparison tells you to set the oven to max, so consider this partly an argument with myself.

What bugged me was the complaint that keeps showing up from people who own a good steel: the bottom is done and the top still looks like it’s waiting for a ride. So I got curious and went looking at what the research says about pizza steel temperature. The answer doesn’t say your steel is bad. It says you may be aiming it wrong.

What everyone tells you

The usual advice is consistent, and it comes from serious people. Modernist Cuisine, which helped put the steel in home kitchens, says to set the oven as high as it will go, with 500°F as a minimum. Baking Steel’s founder puts the ideal range at 500–550°F with a 60-minute preheat. Ooni says to preheat at top temperatures, up to 527°F.

The reasoning isn’t silly. Home ovens top out around 500–550°F, a wood-fired oven runs far hotter, and a hotter bake is a shorter bake. So you take every degree you can get, the same logic behind most home oven temperature advice.

Here’s what those pages skip. I read 13 steel and temperature guides for this piece, and none of them cites a heat-transfer study. They treat the oven setting as one number, when your pizza is cooking from two directions.

What I found when I dug in

The floor: steel isn’t just hot, it’s fast

The clearest work I found is The Physics of Baking Good Pizza by Varlamov, Glatz and Grasso, published in Physics Education in 2018. Their point is simple: the temperature under your crust depends on the floor’s temperature and on how readily the floor material hands over its heat. Firebrick gives it up slowly. Steel doesn’t.

They start from what Roman pizza makers told them: about 626°F (330°C) on a firebrick floor for a thin pie in 2 minutes. Their equation puts the crust’s underside at about 406°F (208°C) on brick. Run the same 626°F on steel and it’s about 572°F (300°C). Their words: “That is too much! The pizza will just turn into coal!” To get back to the target, they calculate that the metal floor should sit near 446°F (230°C).

The ceiling: where the trade-off lives

Now the catch, and the paper is upfront about it. Radiant heat from a surrounding oven falls fast as the temperature drops. The authors calculate about 7.5 kW per square meter at 626°F and about 3.6 at 446°F, which is why their modeled bake stretches from about 125 seconds to about 170.

So just turning the dial down is not the answer. NPR’s report on the paper says lowering the oven to 450°F alone leaves cooked dough with undercooked toppings. The same piece describes the home workaround: a steel preheated to around 430°F, with the broiler handling the top.

Test kitchens and steel makers land nearby

This is where I stopped thinking it was only a physics-class exercise. America’s Test Kitchen warns that the top of a pizza on a steel can come out undercooked in some ovens. Its first fix is switching to broil as soon as the pizza goes in. Its second is a lower rack and 450°F instead of 500°F.

Baking Steel’s own broiler method preheats at 450°F for an hour on the top rack, even though the same page calls 550°F the answer. In the NPR piece, Kenji López-Alt says steel at 500°F can burn a pizza in 60 to 90 seconds.

On one Pizza Making Forum thread, a baker with a steel reading almost 600°F reports the bottom finishing way before the top. A reply describes turning down to around 480°F with broiler time. That’s anecdote, not data, but it matches the math.

The detail nobody mentions: your broiler has a limit

GE’s support page says that with the door shut, the broil element cycles off once the oven reaches 550°F on High Broil, or 450°F on Lo Broil. Whirlpool says its elements have a limiter and cycle at higher settings. So on some ovens, preheating at the absolute max could leave the broiler with little room to run, right when your toppings need it. That’s my reading of those pages, and models vary, so check your manual.

The numbers, side by side

Why the usual advice falls short

Look at the 550°F steel row against the brick row. By this math your crust’s underside runs about 100°F hotter than on that Roman brick floor, while the heat from above is about 25% lower. That’s the imbalance behind a pizza that’s carbon on the bottom and a warm suggestion on top. It’s also a likely contributor to the classic burnt-one-side, underdone-the-other bake.

Maxing the dial buys you some top heat, but you pay for it on the floor. Going from 450°F to 550°F adds about 91°F under the crust in this model. The broiler is the tool that works on the top without touching that equation, which is why I’d rather lean on it than on the bake setting.

There’s overshoot to consider too. Baking Steel reports a steel hitting 597°F in a 550°F oven, and a forum baker reports 600°F-plus. Others land right on target: America’s Test Kitchen’s models all measured 500°F after an hour of preheating. A long preheat is still worth it, but it’s worth knowing what your steel actually reads.

What actually holds up

The real strength of the max-heat camp is speed. A shorter bake generally means less time for the crust to dry out, and NPR’s report flags exactly that risk with cooler bakes.

Plenty of cooks also get pies they love at 500–550°F on a steel, and Baking Steel recommends that range for New York-style at 6–8 minutes. If yours come out balanced, you have no problem to fix. Max heat also makes much more sense on a stone, where the slower material leaves room for it.

Hot floors aren’t automatically the enemy either. A wood-fired oven study in Foods recorded a floor of about 822°F (439°C) and found the bottoms burned far less than the tops. My reading is that a wood-fired oven also pours far more heat onto the top of the pie, which is the balance I’m talking about, not one magic number.

Now the limits of my position, and they’re real. This rests on one simplified model, written for a physics teaching journal. It assumes a thin Roman-style pie, it uses stainless steel values rather than the carbon steel most baking steels use, it treats the floor as holding temperature, and it calls its dough numbers estimates.

I found no controlled test of a home oven comparing steel settings with a broiler, so 450–475°F is my inference, not a measured optimum.

Real life pushes in both directions. Reference tables list carbon steel well above stainless for conductivity, which would make the floor effect stronger.

But the Foods study notes dough doesn’t contact the floor uniformly, America’s Test Kitchen found steels lose temperature faster after the dough lands, and a 2009 engineering paper using an aluminum block in a pan found conduction the weakest of the three heat paths. That setup had poor contact and no preheated steel, but it’s a good reason not to treat these figures as gospel.

Thickness matters as well. Tom Lehmann, the Dough Doctor, has said on PMQ’s forum that a thin steel deck cools too quickly and gives a light bottom bake. He’s describing commercial ovens, but if you own a thin steel, you may well need more heat than I’m suggesting.

My take

What to do instead

This is a starting point for your next bake, built from the sources above. Your oven gets the final vote.

1. Set the rack first. Baking Steel’s method uses the top rack. America’s Test Kitchen suggests moving nearer the center if the top still lags, so treat position as a variable.
2. Preheat at 450–475°F for an hour. Skip the max setting. A 22-pound steel like Modernist Cuisine’s takes time, so patience matters more than the number. If you can, read the surface with an infrared thermometer.
3. Launch and switch to high broil right away. Keep the door shut unless your manual says otherwise, since brands differ. GE says its element stays on with the door open, and Whirlpool says opening the door during broil turns its element off.
4. Stay at the oven. Baking Steel’s table lists 4–6 minutes for 450°F plus broiler. Check the underside early, because López-Alt’s 60-to-90-second warning for steel at 500°F is enough to justify hovering.
5. Move in 25°F steps. That increment is Lehmann’s advice for dialing in a deck oven, and it works as a sensible habit here. Bottom dark first? Go down. Pale, soft bottom with a done top? Go up.

Heavy, wet toppings need a thought too. The physicists note that more water means a longer bake, so keep the moisture in check before you blame the steel. And if you want more on how your oven’s modes behave, my guide to oven settings for pizza covers the basics.
