How can I produce a more soggy Neapolitan pizza crust?

It sounds like you're doing several things differently than the recipe (different flour, different temperature, different baking surface...) though I don't actually see shaping/baking instructions on the recipe you linked. If you want to stick closer to that recipe (than the other answers...), here's a few other thoughts of potential problems and a few things to try to alleviate these potential problems.

• Baking too quickly or overcooking. the baking steel will transfer heat more quickly than a baking stone, a perforated pizza pan, or a sheet pan. Try one of those other baking surface options if you have them, or preheating your steel for a shorter period of time, or cooking for a shorter period of time.
• Different flour. doppio zero flour is (likely) much more finely ground and more highly refined than your bread flour; these differences will impact how your bread behaves, such as water absorption and retention (in addition to the temperature comment you made). You might want to try increasing the water, to see if that does something you like (this recipe is about 65% hydration, so you've got some room before the dough gets really sloppy). Bread flour and 00 flour will (likely) have similar protein content, but you could check that from the respective producers, also. Despite your cost and temperature concerns, have you tried 00 in this recipe just once to see if there's a difference?
• Shaping. Looks like you have a system, but perhaps you've got the dough just a bit too thin in the middle? Might be worth making the center slightly thicker as a test. Also might want to try making one a bit bigger.
• If you're cooking one at a time, try cooking two at a time. They'll each be absorbing some heat, so baking will happen slightly more slowly.

Other questions:

• are you indeed letting the dough ferment and rest for this long? 8-12 hours of initial ferment seems uncommon for conventional yeast. I've seen this long initial mix-and-rest for a (no-yeast) autolyse step, or for (very) sour sourdough. I wonder what the intended effect is...
• I'm also surprised there's nearly zero kneading; gluten development will be... different. It seems like the dough will be lumpy, and the gluten development wouldn't be as uniform. Or, perhaps after 2.5 days fermentation this is enough time to have the dough work itself out on its own. The "bread in 5 minutes per day" franchise also suggests multi-day fridge storage, so I think this is probably a good thing in this case.

Looks good; I think I'll have to try this. Good luck! Post back if you discover some improvements...

Sorry to dig this up months later, but it's a great question, one that I've struggled with also. I have baked pizzas in a 700-800F wood oven, and had the same complaint: beautiful coloration, decent spring, but not moist enough. I'm using dough that's much closer to the Tartine method hydration level than typical pizza dough, so I don't think that the answer lies in just upping hydration, although it might help.

Instead, I have looked at two ways to improve: topping moisture and shaping.

It's hard, and expensive, to get really nice mozz here (in the states). Think about the fancy imported mozzarella di bufala: wet, hardly chewy at all, very milky. It's not what most Americans even think of as mozz. I don't know what kind of cheese you're using, but in my experience, it's hard to go too wet on the cheese in imitating pizza napoletana. I've had better luck just subbing a soft triple cream cheese if I can only get dry chewy mozz. Also, the traditional sauce is crushed raw tomatoes. Not cooked at all - again, much moister than what Americans typically put on pizza. This is a cheaper way of changing the toppings to include more moisture.

Also, I got a clue from Una Pizza Napoletana, where I've had the best version of pizza in this style that I've ever eaten. There's a video on their homepage with some brief glimpses (starting at 40 sec) of Mangieri (chef owner) shaping pies. I was surprised mainly by how big his dough balls are. Those have got to be 8-10oz beasts, and he's making pizzas 12" across from them. There's clearly a lot of dough getting left in the cornicione. Also, his dough doesn't look particularly proofed. I've incorporated some of these things with results moving in the right direction.

All in all, I think there's a reason that this style of pizza is so highly regarded. It's damn hard to make! The pie you pictured is gorgeous, and 99% of people would say it's near-perfect. What makes pizza napoletana different is that at its best it's like a pizza and fresh-out-the-oven loaf of bread rolled into one. Getting the chewy steamy bread part is hard; I hope a bit of this helps.

PS I'm not making perfect neapolitan pies by any means, just aspiring as well! Good luck!

I'm also a lover of so called "Vera Pizza Napoletana". By coincidence, I made yesterday this Neapolitan Pizza style using this Serious Eats method. Also see this step-by-step instructions.

It's all about heat capacity, conduction and radiation. You don't need a 1000°F oven to bake your pizza because doing it on a skillet will have almost the same effect since it will deliver more heat at lower overall temperature. The stainless steel and aluminum core of a good skillet can both hold significantly more energy and better at conduct that energy into the bottom of a pizza.

1. Preheat a skillet until 500°F, if you don't have a thermometer follow this tip:

a drop of water dropped on its surface forms a bead that skids around

2. Transfer the stretched dough to the skillet and cook it around 1 minute, flip, cook a little more and burn the "cornicione" on direct flame of the gas burner.

3. Transfer it back to a clean surface put the topping, in this case tomato sauce, mozzarella and basil leaves.

4. Transfer it back to the skillet at low-medium heat and cook it until mozzarella is melted, but still soggy.

It's incredibly easy to do and the outcome is very good.

I think that baking at lower temperature will do the opposite effect. Lower heat will dry out your pizza. If you want it soggy, you want high heat to cook the dough before the fillings dry.

Perhaps this is an obvious answer - but if your center is too dry, add moisture. If you're happy with the edges and the rest of the pizza, then meddling with other variables (like time, temp, or flour) might disturb the things that work - a possibility to keep in mind for if smaller adjustments don't work, but not my first adjustment.

For myself, when I want to adjust moisture in a recipe, my first go-to is to sprinkle water in it. Low tech, but it works for me - it promotes a beautiful melting in slightly drier cheeses, and keeps crusts from drying out (my typical problem). Maybe sprinkle a tablespoon of water over the pizza, or maybe splash it right down over the center, or maybe precisely eyedropper the water just where your want it (depending on your textural preferences). You can add the water while the pizza is being assembled (for hydrating ingredients), or just before you bake (for a slightly less cooked center), or after it is taken out of the oven (for general sogginess after it has been cooked properly).

After that, evaluate the difference and tweak accordingly. Maybe you need more water, or to soak individual ingredients pre-assembly, or sprinkle over the top more evenly, or place a puddle of water on your serving plate, for it to sog up the bottom crust center after the pizza is placed on it. Maybe you want a little more flavor, and would like to try sprinkling milk instead of water - or you want to add a little more oil to the center. Maybe the introduction of wetter ingredients (like Gabriel Saunder's suggestion of cream cheese instead of, or as well as, the mozzerella) will help, or you want a moister sauce.

After that, you might discover other tweaks that improve your recipe, or that you want to try a bigger change (like the aforementioned time baking, temperature, and flour type). You might find all your problems are solved with an eyedropper of water (or other liquid) at your workstation.

I'm not sure why anyone would want a soggy crust, however if that's what you want lose the baking steel. The reason for using a steel or stone is to give you a crunchy crust, try using a baking tray instead.

Also, you can try baking at a lower temperature, not a higher one. Lose 100F on the oven and you're more likely to get sogginess.

To me it sounds like you are doing it right, not wrong. Soggy - why?!
