This easy Chicago-style deep dish pizza is made with two uncooked pizza crusts, sliced cooked chicken, mozzarella, and a simple passata tomato sauce. Baked in a cast-iron pan, it has a thick pizza pie structure with a golden crust and rich sauce on top.
In a bowl, combine 1¼ cups (300 g) tomato passata, 2 tablespoons tomato paste, ½ teaspoon salt, ¼ teaspoon black pepper, 1 tablespoon dried oregano, and 2 tablespoons extra virgin olive oil. Mix well and set aside.
Grease a cast-iron pan with 1 tablespoon melted butter and sprinkle 2 tablespoons semolina over the base and sides.
Place 1 uncooked pizza crust into the pan, pressing it into the bottom and up the sides to form a deep crust.
Add 1 pound (500 g) sliced cooked chicken evenly over the base, then cover with 4 cups (400 g) shredded mozzarella cheese.
Place the second uncooked pizza crust over the top and press the edges together to seal. Trim any excess dough if needed.
Pour the prepared sauce over the top and spread it evenly. Use a fork or knife to poke a few small holes in the top crust.
Bake for 20 minutes, then reduce the oven temperature to 375°F (190°C) and bake for another 10 minutes, until golden and cooked through.
Remove from the oven and let it rest for 10 minutes.
Sprinkle with ¼ cup (20 g) grated Pecorino cheese, slice, and serve.
Notes
Butter and Semolina the Pan Well: I like to coat the cast-iron pan with melted butter and semolina so the crust bakes with a golden, slightly crisp base. Press the Dough Up the Sides: Push the first pizza crust firmly into the pan and up the sides, as I find this helps it hold the chicken and mozzarella better while baking. Seal the Edges Carefully: I like to press the top and bottom crusts together well so the filling stays tucked inside as the pizza bakes. Let It Rest Before Slicing: Let the pizza sit for 10 minutes after baking, as I find the layers settle better and the slices hold their shape.
