Chicago Style Deep Dish Pizza
By Marco DeLuca
Rate this recipe
Chicago deep-dish was born in 1943 at Pizzeria Uno, where founder Ike Sewell reimagined pizza as a knife-and-fork meal rather than a foldable street slice. The signature is the construction, which is built upside-down from a Neapolitan pie: a tall, buttery cornmeal crust is pressed up the sides of a deep pan, lined with sliced mozzarella, layered with sausage, and finished with a chunky tomato sauce on top so the cheese never scorches during the long bake. That inversion is not a gimmick. Burying the cheese against the dough shields the crust from the wet sauce, while the uppermost tomato layer caramelizes slightly in the oven. The cornmeal gives the crust its tell-tale golden crackle and a faintly sweet, almost shortbread snap at the edge. A true deep-dish is hearty enough that two slices make a meal, which is why Chicagoans treat it as a weekend sit-down occasion rather than weeknight takeout. Made well, it is a structural marvel: a savory pie that holds a half-inch of molten cheese and sauce without collapsing, rewarding the patience its forty-minute bake demands.
Ingredients
Serves 8Instructions
- 1
Preheat oven to 425°F (220°C). Coat a 12-inch round deep-dish pizza pan or cast-iron skillet generously with vegetable oil.
- 2
Press the dough into the bottom and up the sides of the pan.
- 3
Layer the sliced mozzarella cheese directly over the dough bottom. This protects the crust from getting soggy.
- 4
Distribute the raw sausage chunks evenly over the cheese. Press them down slightly.
- 5
In a bowl, mix crushed tomatoes with oregano and garlic powder. Spread this sauce over the sausage layer.
- 6
Sprinkle the top with grated Parmesan cheese.
- 7
Bake for 35-45 minutes, or until the crust is golden and the filling is bubbly. If the crust browns too quickly, cover edges with foil.

Let rest for 10 minutes before slicing.
Chef's Tips
- ✦ This recipe places raw Italian sausage directly on the pie, so bake until the sausage reaches an internal temperature of 160°F (71°C) on an instant-read thermometer before serving.
- ✦ Oil the pan generously and use a cast-iron skillet if you have one; the retained heat fries the crust bottom into a crisp, golden shell.
- ✦ Press the dough up the full height of the pan walls while it is cool and relaxed, then let it rest 10 minutes so it does not shrink back during baking.
- ✦ Always layer the sliced mozzarella directly on the dough and the sauce on top; this inverted order shields the crust from sauce moisture and keeps it from going soggy.
- ✦ Rest the baked pie for a full 10 minutes before slicing so the molten cheese and sauce set enough to hold a clean wedge instead of sliding apart.
Ingredient Substitutions
-
cornmeal pizza dough → gluten-free pizza dough blended with fine cornmeal
Use a sturdy GF blend rated for high hydration; press cold and chill 10 minutes so it holds the pan walls without slumping.
-
sliced mozzarella cheese → plant-based mozzarella slices or blocks
Lay overlapping slices so the dairy-free cheese still forms an unbroken moisture barrier over the dough.
-
raw Italian sausage → plant-based Italian sausage or seasoned mushroom-lentil crumble
Pre-cook plant crumbles to drive off water, since they release more liquid than pork and can soak the crust.
-
crushed tomatoes → hand-crushed San Marzano whole peeled tomatoes
Drain excess juice first; San Marzanos give a sweeter, less acidic top layer that needs no added sugar.
-
grated Parmesan cheese → grated Pecorino Romano or nutritional yeast
Pecorino is sharper and saltier, so scale back any added salt; nutritional yeast keeps the finish dairy-free.

Frequently Asked Questions
Why does the sauce go on top of the cheese in deep-dish pizza? ▼
The inverted layering is what defines Chicago deep-dish. Cheese sits directly on the dough to form a moisture barrier that keeps the thick crust from turning soggy, while the chunky tomato sauce on top is exposed to oven heat and concentrates in flavor. Reversing the order would waterlog the crust during the long bake.
Can I make the dough ahead of time? ▼
Yes. The dough can be made up to 48 hours ahead and held in the refrigerator, which actually improves flavor and structure. Let it sit at room temperature for about 30 minutes before pressing it into the pan so it stretches without tearing or springing back.
How do I know the raw sausage is fully cooked? ▼
Because this pie uses raw sausage placed directly on the cheese, check it with an instant-read thermometer; the sausage is safe at an internal temperature of 160°F (71°C). The long 35 to 45 minute bake is designed to cook the sausage through while the crust browns.
Can I freeze deep-dish pizza? ▼
Yes, deep-dish freezes well because of its sturdy structure. Cool it completely, wrap individual slices tightly, and freeze for up to two months. Reheat from frozen in a 375°F (190°C) oven for 20 to 25 minutes so the center heats through and the crust re-crisps.
What pan should I use if I don't have a deep-dish pan? ▼
A 12-inch cast-iron skillet is the best substitute and arguably better, since it conducts heat aggressively and crisps the crust bottom. A 9 to 10 inch round cake pan with tall sides also works; just oil it generously and expect a slightly thicker pie.
Why is there cornmeal in the crust? ▼
Cornmeal is a hallmark of Chicago deep-dish dough. It adds a subtle sweetness and a distinctive golden, crackly snap to the crust edge, and its coarse texture helps the bottom fry crisp against the oiled pan rather than going dense.
