This cast iron method delivers a buttery crust with perfect structure to hold the signature layers of Chicago-style pizza. The deep skillet creates ideal heat distribution for even cooking.

You’ll achieve a golden, flaky base supporting rich cheese and sauce layers, just like the original. The technique ensures professional results without special equipment.

Ingredients for Chicago Deep Dish Pizza Recipe Cast Iron

Buttery crust, melty cheese, and rich sauce layers come together in this cast iron masterpiece.

For the crust, King Arthur Flour is the gold standard—consistent protein content for structure. The butter must be unsalted to control sodium levels in the dough. Find fine cornmeal at Whole Foods or the baking aisle of most supermarkets. Yeast freshness is critical; check the expiration date and store unopened packets in the freezer for longer shelf life.

No cornmeal? Semolina or breadcrumbs work as substitutes for texture. For cheese, Sargento or BelGioioso brands shred beautifully without clumping. Vegetarian? Swap sausage for mushrooms or roasted bell peppers. The sauce can be homemade, but Rao’s or Victoria jarred sauces deliver consistent quality without the effort.

The dough can rest overnight in the fridge for deeper flavor development. Baked pizza keeps 3-4 days refrigerated, though it’s best fresh. Reheat slices in a skillet to revive the crust’s crispness. Freeze uncooked dough balls for up to 1 month.

Step-by-Step Instructions for Chicago Deep Dish Pizza in Cast Iron

Master this technique for a buttery crust that holds up to the hearty layers of cheese and sauce.

Step 1: Prepare and Proof the Dough

In a stand mixer fitted with a dough hook, combine the 3.25 cups All-Purpose Flour, 0.5 cup Cornmeal, 1 tbsp Granulated Sugar, 2.25 tsp Active Dry Yeast, and 1.5 tsp Salt. With the mixer running on low, slowly pour in the 0.75 cup Unsalted Butter (melted and cooled) and 1.25 cups Warm Water.

Increase the speed to medium and knead for 6-8 minutes until the dough is smooth and elastic. It should pull away from the sides of the bowl but still feel slightly tacky. Transfer to a lightly oiled bowl, cover with a damp towel, and let rise in a warm place for 1-2 hours or until doubled in volume.

Step 2: Cook and Prepare the Fillings

While the dough rises, cook the 0.5 lb Italian Sausage in a skillet over medium heat until browned and crumbled, about 8-10 minutes. Drain any excess fat and set aside. Shred the 1 lb Low-Moisture Mozzarella Cheese and 8 oz Sharp Cheddar Cheese, and thinly slice the 0.25 cup Fresh Basil Leaves.

Lightly grease a 12-inch cast iron skillet with the 2 tbsp Olive Oil, making sure to coat the sides as well. This prevents sticking and adds a rich flavor to the crust. Preheat your oven to 425°F to ensure it’s fully heated when you’re ready to bake.

Step 3: Shape the Crust in the Skillet

Once the dough has risen, punch it down and transfer it to a lightly floured surface. Roll it out to a 14-inch round, slightly larger than your skillet. Carefully place the dough into the prepared skillet and press it firmly into the bottom and up the sides, creating a thick, even layer.

Use your fingers to crimp the edges, forming a sturdy rim to hold the fillings. If the dough resists, let it rest for 5 minutes before continuing. This ensures the crust bakes evenly without shrinking.

Step 4: Layer the Cheese, Sausage, and Sauce

Sprinkle the shredded Low-Moisture Mozzarella Cheese and Sharp Cheddar Cheese evenly over the dough, covering the bottom completely. Scatter the cooked Italian Sausage over the cheese. Pour the 2 cups Pizza Sauce evenly over the top, spreading it to the edges without disturbing the layers below.

Sprinkle the 0.25 cup Parmesan Cheese over the sauce for an extra layer of flavor. The sauce should be the topmost layer, which helps prevent the crust from becoming soggy during baking.

Step 5: Bake to Golden Perfection

Place the skillet in the preheated 425°F oven and bake for 25-30 minutes, or until the crust is deep golden brown and the cheese is bubbly and slightly caramelized at the edges. Rotate the skillet halfway through baking to ensure even browning.

Remove from the oven and let the pizza rest in the skillet for 10 minutes before slicing. This allows the layers to set, making it easier to serve. Garnish with the sliced Fresh Basil Leaves just before serving for a fresh, aromatic finish.

Common Mistakes When Making This Recipe

🍕 Overloading the Cast Iron Skillet

Using too much dough or toppings can lead to a soggy crust and uneven cooking in your cast iron skillet. The deep dish needs room for layers to bake properly.

Fix: Stick to 1.5 lbs of dough for a 10-inch skillet and layer toppings sparingly.

⏰ Skipping the Pre-Bake for the Crust

Adding sauce and cheese directly to raw dough can make the bottom undercooked. The crust needs a head start to firm up before toppings are added.

Fix: Blind-bake the crust for 10-12 minutes at 375°F before adding fillings.

🌡️ Overheating the Cast Iron

Cast iron retains heat, and too-high temperatures can burn the crust before the pizza cooks through. Deep dish requires steady, even heat.

Fix: Bake at 375°F and avoid preheating the skillet excessively.

🥄 Saucing Too Early

Adding sauce directly on raw dough can make it gummy. In Chicago-style deep dish, sauce goes on top of cheese and fillings to prevent a mushy base.

Fix: Layer cheese first, then toppings, and finish with sauce to keep the crust crisp.
