Authentic Chicago-Style Deep Dish Pizza Recipe 🍕

There is pizza, and then there is Chicago-style deep dish pizza—a culinary masterpiece featuring a buttery, flaky crust, layers of gooey mozzarella, savory Italian sausage, and a rich, chunky crushed tomato sauce on top.

Unlike traditional thin-crust pizzas, deep dish is built upside down to prevent the cheese from burning during its longer bake time. If you’ve ever wanted to recreate iconic Windy City pizza at home, this complete guide will walk you through every step.

🛒 Ingredients You’ll Need

🌾 For the Buttery Crust

• 3 ¼ cups (415g) All-purpose flour or bread flour
• ½ cup (65g) Yellow cornmeal (adds that signature Chicago crunch!)
• 1 ¼ tsp Salt
• 1 tbsp Granulated sugar
• 2 ¼ tsp (1 packet) Active dry yeast
• 1 ¼ cups (300ml) Warm water (105°F–110°F / 40°C–43°C)
• ½ cup (115g) Unsalted butter, melted
• 2 tbsp Olive oil (for coating the pan)

🍅 For the Chunky Tomato Sauce

• 1 tbsp Unsalted butter
• 1 small Yellow onion, finely grated
• 3 cloves Garlic, minced
• 1 tsp Dried oregano
• 1 tsp Dried basil
• ½ tsp Red pepper flakes (optional for heat)
• 1 can (28 oz / 800g) Crushed San Marzano tomatoes (drained slightly)
• ½ tsp Salt

🧀 For the Filling & Toppings

• 1 lb (450g) Whole-milk mozzarella cheese, sliced or coarsely shredded
• ½ lb (225g) Raw mild Italian sausage, removed from casings
• ½ cup (50g) Freshly grated Parmesan or Romano cheese

👩‍🍳 Step-by-Step Instructions

Step 1: Make the Dough 🍞

1. In a large bowl or stand mixer, whisk together the warm water, sugar, and yeast. Let it sit for 5–10 minutes until frothy.
2. Add the melted butter, flour, cornmeal, and salt. Mix on low speed using a dough hook (or knead by hand) for 4–5 minutes until a smooth, slightly tacky dough forms.
3. Form the dough into a ball, place it in a lightly oiled bowl, cover with a damp towel, and let it rise in a warm spot for 1 to 1.5 hours (until doubled in size).

Step 2: Prepare the Sauce 🍅

1. Heat 1 tbsp of butter in a saucepan over medium heat.
2. Add the grated onion, garlic, oregano, basil, red pepper flakes, and salt. Cook for 3–4 minutes until fragrant.
3. Stir in the crushed tomatoes. Reduce heat to low and simmer uncovered for 20 minutes until the sauce thickens and loses excess moisture. Remove from heat to cool.

Step 3: Laminate for Extra Flakiness (Pro-Tip!) 🧈

1. Punch down the dough and roll it out into a 15×12-inch rectangle on a floured surface.
2. Spread 2 tablespoons of softened butter over the surface, then roll the dough into a tight log (like a cinnamon roll).
3. Cut the log in half (one for each pizza), flatten each half into a disc, cover, and chill in the refrigerator for 30 minutes.

Step 4: Assemble the Pizza 🍕

1. Preheat your oven to 425°F (220°C). Generously coat a 12-inch deep-dish cake pan or cast-iron skillet with olive oil.
2. Roll out one dough disc into a 14-inch circle. Press it into the bottom and up the sides (about 1.5 inches) of your pan.
3. Layer 1 (The Cheese): Place the mozzarella slices directly on the bottom crust.
4. Layer 2 (The Meat): Pinch small pieces of raw Italian sausage and spread them evenly over the cheese.
5. Layer 3 (The Sauce): Ladle the thick tomato sauce evenly over the top.
6. Sprinkle with freshly grated Parmesan cheese.

Step 5: Bake to Golden Perfection 🔥

1. Bake for 30 to 35 minutes until the crust edges are deep golden brown and the sauce is bubbling. (If the crust edges brown too quickly, tent the pan loosely with aluminum foil).
2. Remove from the oven and let the pizza rest for 10 minutes before slicing. This allows the cheese to set so it doesn’t spill out!

💡 Chef’s Secret Tips

• Don’t Skip the Cornmeal: Cornmeal gives the crust its authentic yellowish tint and distinct Chicago flavor.
• Whole-Milk Mozzarella Only: Avoid pre-shredded low-fat mozzarella; it contains anti-caking agents that prevent that iconic stretchy cheese pull.
• Raw Sausage Technique: Placing raw sausage under the hot sauce layer allows it to steam cook perfectly without drying out.
