Why Does Neapolitan Pizza Need a Hot Oven?

Pizza is magic.

Not in the Harry Houdini, “I’m gonna shackle myself to this pepperoni and escape while it’s in the oven” way. Not in the David Copperfield, “Now you see the pizza oven, now you don’t!” way. Not even in the Harry Potter “enlargium buttocks” kind of way.

I’m talking the much more exciting kind of magic. The kind that can transform a few simple ingredients—water, flour, salt, yeast, and a few toppings—into one of the pinnacles of human culinary achievement, all through the application of a bit of good technique and a whole lot of heat.

It’s possible to make really good, even fantastic pizza in a regular home oven. At least the styles of pizza that are typically baked at or below the 550°F (290°C) the average home oven maxes out at. Chicago thin crust. Detroit. My Foolproof Pan Pizza. Even New York pizza can be made succesfully with the help of a baking steel—a tool that replaces your pizza stone to increase the rate of heat transfer.

But Neapolitan pizza, with its charred flavor and wonderfully light, moist, crisp crust? It can’t be done. (At least not without voiding your warranty and homeowners insurance by breaking the thermostat on your oven). I myself have spent a couple decades testing and writing recipes that attempt to hack your way into success in the home kitchen, with varying degrees of success.

No, when it comes to great Neapolitan pizza at home, there is one great barrier to success. It’s not the quality of the ingredients. It’s not experience (you can always learn to stretch, top, and bake pizza better). It’s not even bad recipes or bad dough.

It’s heat.

Luckily, there’s a solution. Just get yourself an outdoor pizza oven like the ones made by Ooni, who I’ve teamed up with to produce a series of recipes and videos showing what you can do with one of these high-powered beasts capable of heating up to nearly 1000°F (540°C)

But first, let’s talk about what exactly happens when you put a pizza in a hot oven..

Blazing Fast, Blazing Good: The Importance of High Heat

So what turns a floppy, moist round of dough into a light, crisp, cloud-like pizza with a crackly crust and a charred, blistered, leopard-spotted surface? Heat, and lots of it.

It's all thanks to something called oven spring. When that cold dough hits the heat, the tiny bubbles of carbon dioxide inside it, along with the trapped water turning to steam, start to puff up like balloons. This stretches out the stretchy stuff in the dough, called gluten. But it's a race against time. Soon enough, that gluten will firm up and stop the rising. So, the trick to getting that light, airy texture is to make those bubbles grow as big and fast as possible before the gluten sets. To do that, you want to blast the dough with heat while it’s still raw.

This not only improves the dough’s interior texture, but it also creates hundreds of tiny, thin-walled blisters on its surface that brown faster than the rest of the dough (or blacken, if you, like me, enjoy your pizza darker–”It’s not burnt, it’s artfully charred.”). This creates the signature pattern of “leopard spots” on a Neapolitan crust, adding both texture and flavor.

Cook time is also important. In a regular home oven, pizza can take several minutes or even tens of minutes to bake. With a properly heated, 900°F oven, a pizza takes between 60 and 90 seconds to cook. Why does this matter? The longer a pizza spends in the oven, the more moisture is evaporated out of it. Thus a pizza baked for longer in a lower temperature oven will lose more moisture, creating a stiffer, more crackery crust than the quail-egg-shell-thick crust you achieve when cooking faster with a hotter oven.

Nothin' but Oven

I’ve been testing models of indoor and outdoor pizza ovens for nearly two decades now, across my time at Cook’s Illustrated, Serious Eats, and as a solo producer. I’ve also tested virtually every model of Ooni pizza oven since the very first one (back when they were still called Uuni) and while you could crank even that pellet-fired, relatively lightweight and petite oven to the required temperatures with a bit of fiddling, boy have these ovens come a long way in terms of ease of use and functionality. No more buying specialty fuels. No fiddling with a wood or coal fire and their fickle demands for fresh airflow. 

I won’t go Burt Wonderstone on you and cast any illusions as to the difficulty of getting used to a high heat pizza oven and the speed at which a pizza cooks. I’ve never met someone who bakes in a hot oven that didn’t burn their first pizza to a crisp. Neapolitan pizza-making is not a spectator sport, and without constant vigilance, a pizza can go from perfectly charred and blistered to literally on fire within the span of a few seconds.

That said, if you put in the practice and are willing to sacrifice a few pies early in the process, you'll soon be serving charred, leaopard-spotted, light, crisp beauties to a yardfull of happy friends and family.

Like magic.
