Chicago-Style Deep-Dish Pizza
Yield: 4 to 6 servings
Prep Time: 2 hours 30 minutes | Bake Time: 20 to 30 minutes

For the Dough:
3¼ cups all-purpose flour
½ cup yellow cornmeal
1½ teaspoons salt
2 teaspoons sugar
2¼ teaspoons instant yeast
1¼ cups water, room temperature
3 tablespoons unsalted butter, melted
4 tablespoons unsalted butter, softened
1 teaspoon + 4 tablespoons olive oil, divided

For the Sauce:
2 tablespoons unsalted butter
¼ cup grated onion
¼ teaspoon dried oregano
½ teaspoon salt
2 garlic cloves, minced
1 (28-ounce) can crushed tomatoes
¼ teaspoon sugar
2 tablespoons coarsely chopped fresh basil
1 tablespoon olive oil
Freshly ground black pepper

For the Toppings:
1 pound mozzarella cheese, shredded (about 4 cups)
(Pepperoni)
¼ cup grated Parmesan cheese

1. Make the Dough: Whisk together the flour, cornmeal, salt, sugar, and yeast in a large bowl. Add water and melted butter and mix on low speed, using a dough hook, until fully combined, 1 to 2 minutes, scraping sides and bottom of bowl occasionally. Increase speed to medium and knead until dough is glossy and smooth and pulls away from sides of bowl, 4 to 5 minutes. (You can easily make this by hand, mixing in the water and butter with a spatula and then kneading by hand.)

2. Coat a large bowl with 1 teaspoon olive oil. Using greased spatula, transfer dough to bowl, turning to coat the dough in oil; cover tightly with plastic wrap. Let rise at room temperature until nearly doubled in volume, 45 to 60 minutes.

3. Make the Sauce: While dough rises, heat the butter in a medium saucepan over medium heat until melted. Add onion, oregano, and salt; cook, stirring occasionally, until liquid has evaporated and onion is golden brown, about 5 minutes. Add garlic and cook until fragrant, about 30 seconds. Stir in tomatoes and sugar, increase heat to high, and bring to a simmer. Lower heat to medium-low and simmer until reduced to about 2½ cups, 25 to 30 minutes. Off the heat, stir in the basil and olive oil, then season with salt and pepper.

4. Laminate the Dough: Turn the dough out onto dry work surface and roll into a 15×12-inch rectangle. Using an offset spatula, spread the softened butter over the surface of the dough, leaving a ½-inch border along the edges. Starting at the short end, roll the dough into a tight cylinder. With seam side down, flatten the cylinder into an 18×4-inch rectangle. Cut rectangle in half crosswise. Working with one half, fold into thirds like a business letter; pinch seams together to form ball. Repeat with remaining half. Return balls to oiled bowl, cover tightly with plastic wrap, and let rise in refrigerator until nearly doubled in volume, 40 to 50 minutes. Meanwhile, adjust oven rack to lower position and preheat oven to 425 degrees F.

5. Bake the Pizzas: Coat two 9-inch round cake pans with 2 tablespoons olive oil each. Transfer 1 dough ball to dry work surface and roll out into a 13-inch circle. Transfer dough to the pan by rolling the dough loosely around a rolling pin and unrolling into pan. Lightly press dough into pan, working into corners and 1 inch up sides. If dough resists stretching, let it relax for 5 minutes before trying again. Repeat with remaining dough ball.

6. For each pizza, sprinkle 2 cups mozzarella evenly over surface of dough. (If you’re using any meat or veggie toppings, add them now, on top of the cheese.) Spread 1¼ cups tomato sauce over the cheese (or toppings) and sprinkle 2 tablespoons Parmesan over sauce. Bake until crust is golden brown, 20 to 30 minutes. Remove pizza from oven and let rest 10 minutes before slicing and serving.
