Detroit-style, Sicilian, and deep dish pizza have moved from niche to menu staple. Square pies with caramelized cheese edges photograph well, command higher prices, and give independent pizzerias a way to stand apart from the big chains. But thick-crust pizza has its own delivery problem. Instead of a limp, floppy slice, you get a gummy, doughy center that customers describe as “undercooked” even when it came out of the oven perfect.
If you sell pan pizza for delivery or carryout, here is why the center goes gummy and what you can do about it.
Why Thick-Crust Pizza Turns Gummy in the Box
A thin crust has very little crumb, so moisture mostly affects its surface. A thick, open-crumb pan crust acts more like a sponge. It has plenty of air pockets that happily soak up anything wet sitting on top of it.
Three things work against you on a deep pan pie:
- More toppings, more moisture. Pan pizzas carry heavier loads of cheese, sauce, sausage, and vegetables. All of that releases water and oil as it cools.
- Heat stays trapped longer. A thick pie holds heat, so it keeps steaming inside the box for the entire ride. That steam condenses and settles into the top layer of the crumb.
- The center bakes last. The edges and bottom get direct contact with a hot, oiled pan. The middle of the top surface is the least-baked area, and it is exactly where the toppings are heaviest.
The result is a pie with a crunchy, fried bottom and a wet, doughy band just under the sauce. Customers notice it right away.
How to Keep Detroit-Style and Deep Dish Pizza Crispy for Delivery
1. Par-Bake or Dock the Dough When Volume Allows
Many successful square-pie shops par-bake their dough in the pan before topping. This sets the crumb structure so it resists soaking. If par-baking does not fit your workflow, at least dock the center of the dough so it bakes more evenly and does not balloon.
2. Watch Your Sauce Placement and Consistency
Detroit-style pizza traditionally puts the sauce on top in stripes after the bake, partly because it keeps the crust drier. If you sauce first, use a thicker, cooked-down sauce and keep the layer thin in the center. Watery raw sauce on a thick crust is a recipe for a gummy middle.
3. Pre-Cook Wet Toppings
Sausage, mushrooms, peppers, onions, and spinach all release liquid during and after the bake. Pre-cooking and draining them removes a big chunk of that water before it ever hits the dough. On a heavily loaded pan pizza, this step matters even more than it does on a thin pie.
4. Put a Moisture Barrier Under the Toppings
Even with good prep, a thick pie will release moisture in the box. That is where a topping conditioner like Krisp-It helps. Sprinkle 1/2 to 1 ounce over the center two-thirds of the pie, under the cheese and toppings. It absorbs the water and oil that toppings release, which is about 70% of the soggy pizza problem, before it can migrate into the crumb.
Krisp-It is made from simple ingredients (bleached wheat flour, salt, sugar, and yeast), so it does not change taste or appearance. It costs pennies per pizza, which is easy to justify on a premium square pie. On larger pans, just scale the amount to cover the center area where toppings are heaviest. Our how-to-use guide covers placement in more detail.
5. Rest on a Rack, Then Vent the Box
Pull the pie from the pan as soon as it comes out of the oven and let it sit on a wire rack for 30 to 60 seconds. Leaving it in the pan steams the bottom and undoes the crunch you worked for. Then box it with vents open so steam escapes rather than raining back down on the pizza.
6. Cut Smart
Every cut creates a new path for moisture to travel along. Some shops send square pies lightly scored instead of fully cut, letting the customer finish slicing at home. If you do cut, use a sharp rocker blade so you do not press toppings and sauce down into the crust.
Why This Matters for Your Bottom Line
Square and deep dish pizzas usually carry higher ticket prices and better margins than standard rounds. That makes them worth protecting. A gummy center leads to the same outcomes as any soggy pizza:
- Remake requests and refunds that wipe out the premium margin
- Reviews calling the pizza “raw” or “doughy in the middle”
- Customers who try your specialty pie once and go back to ordering the cheapest option, or go elsewhere
When a thick-crust pie arrives with a crisp bottom and a set, airy crumb all the way through, it becomes the item people come back for and recommend to friends.
Test It Yourself
Bake two identical pan pizzas: one with your current build and one with a sprinkle of Krisp-It under the toppings. Box them both, let them sit for 20 to 30 minutes like a normal delivery, and cut through the center. Look at the layer just under the sauce. The difference is usually easy to see and feel.
