Foolproof Pan Pizza

I've got a confession to make: I love pan pizza.

I'm not talking deep-dish Chicago-style with its crisp crust and rivers of cheese and sauce, I'm talking thick-crusted, fried-on-the-bottom, puffy, cheesy, focaccia-esque pan pizza of the kind that you might remember Pizza Hut having when you were a kid, though in reality, most likely that pizza never really existed—as they say, pizzas past always look better through pepperoni-tinted glasses.

It would arrive at the table in a jet black, well-worn pan, its edges browned and crisped where the cheese has melted into the gap between the crust and the pan. You'd lift up a slice and long threads of mozzarella pull out, stretching all the way across the table, a signpost saying "hey everyone, it's this kid's birthday!" You'd reach out your fingers—almost involuntarily—grasping at those cheese strings, plucking at them like guitar strings, wrapping them around your fingers so you can suck them off before diving into the slice itself.

That perfect pan pizza had an open, airy, chewy crumb in the center that slowly transformed into a crisp, golden-brown, fried crust at the very bottom and a soft, thin, doughy layer at the top right at the crust-sauce interface. It was thick and robust enough to support a heavy load of toppings, though even a plain cheese or pepperoni slice would do.

It's been years since I've gone to an actual Pizza Hut (they don't even exist in New York aside from those crappy "Pizza Hut Express" joints with the pre-fab, lukewarm individual pizzas), but I've spent a good deal of time working on my own pan pizza recipe to the point that it finally lives up to that perfect image of my childhood pan pizza that still lives on in my mind.

If only pizza that good were also easy to make. Well here's the good news: It is. This is the easiest pizza you will ever make. Seriously. All it takes is a few basic kitchen essentials, some simple ingredients, and a bit of patience.

The way I see it, there are three basic difficulties most folks have with pizza:
  • Problem 1: Kneading. How long is enough? What motion do I use? And is it really worth the doggone effort?
  • Problem 2: Stretching. Once I've got that disk of dough, how do I get it into the shape of an actual pizza, ready to be topped?
  • Problem 3: Transferring. Ok, let's say I've got my dough made and perfectly stretched onto my pizza peel. How do I get it onto that stone in the oven without disturbing the toppings or having it turn into a misshapen blob?
This recipe avoids all three of those common pitfalls, making it pretty much foolproof. To be perfectly honest, every single one of these steps has been done before, and none of it is rocket science. All I'm doing is combining them all into a single recipe.

You can jump straight into a full step-by-step slideshow of the process or find the exact measurements and instructions in the recipe here, or read on for a few more details on what to expect and how we got there.
By now, everybody and their baker's heard about no knead dough. It's a technique that was developed by Jim Lahey of Sullivan Street Bakery and popularized by Mark Bittman of the New York Times. The basic premise is simple: mix together your dough ingredients in a bowl just until they're combined, cover it, and let time take care of the rest. That's it.

So how does it work? Well the goal of kneading in a traditional dough is to create gluten, a web-like network of interconnected proteins that forms when flour is mixed together with water. All wheat flour contains some amount of protein (usually around 10 to 15%, depending on the variety of wheat). In their normal state, these proteins resemble tiny crumpled up little balls of wire. With kneading, your goal is to first work these proteins until they untangle a bit, then to rub them against each other until they link up, forming a solid chain-link fence.

It's this gluten matrix that allows your dough to be stretched without breaking, and what allows it to hold nice big air bubbles inside. Ever have a dense under-risen pizza crust? It's because whoever made it didn't properly form their gluten in the process.

Now you can see how how this can take a lot of work. Kneading, aligning, folding, linking. That's why most pizza dough recipes takes a good ten to twenty minutes of elbow grease or time in a stand mixer.

But there's another way.

See, flour naturally contains enzymes that will break down large proteins into smaller ones. Imagine them as teeny-tiny wire cutter that cut those jumbled up balls of wire into shorter pieces. The shorter the pieces are, they easier it is to untangle them, and the easier it is to then align them and link them up into a good, strong network. No-knead dough recipes take advantage of this fact.

Over the course of an overnight sit at room temperature, those enzymes get to work breaking down proteins. Meanwhile, yeast starts to consume sugars in the flour, releasing carbon dioxide gas int he process. These bubbles of gas will cause the dough to start stretching, and in the process, will jostle and align the enzyme-primed proteins, thereby creating gluten.

Simply allowing the dough to sit overnight will create a gluten network at least as strong (if not stronger!) than a dough that had been kneaded in a mixer or by hand, all with pretty much zero effort. Indeed, the flavor produced by letting yeast do its thing over the course of this night will also be superior to that of any same-day dough. Win win!

Other than time, the only real key to a successful no-knead dough is high hydration. Specifically, the water content should be at least 60% of the weight of the flour you use. Luckily, high hydration also leads to superior hole structure upon baking. I go for about 65%.
