Chicago-style deep dish pizza with Italian Sausage

The first bite is pure contrast: a crisp, buttery crust that gives way to a deep, tomato-forward filling and bubbling mozzarella — this is Chicago-style deep dish pizza built for hungry company. After perfecting this version over dozens of tests and refining the dough during my years as a pizzeria chef, I settled on a cornmeal-scented crust and a sausage-forward filling that hold up under long bake times. This recipe balances high-heat caramelization with slow, even cooking so the sausage stays juicy and the cheese melts without turning greasy. If you want a comforting pasta companion, consider the rich creamy Italian sausage gnocchi for a sausage-forward dinner the whole family will love. Read on for ingredient notes, precise steps with metric and imperial measures, and pro tips to get a bakery-quality deep dish at home.

Why This Recipe Works

A cornmeal-enriched dough creates a crisp, slightly gritty crust that resists sogginess under sauce.
Browning the sausage first concentrates flavor and renders fat so the filling stays rich without becoming greasy.
Layering cheese under sauce keeps the top from burning and traps steam, which yields a tender interior and a crisp edge.
A moderate proof (rise) gives the crust structure without long fermentation, which is practical for home cooks.
Tested repeatedly in cast-iron and steel pans to confirm consistent bake times and reliable crust color.

Ingredients Breakdown

Dough (forms the structural shell): 500 g (4 cups) all-purpose flour, 60 g (½ cup) fine yellow cornmeal, 10 g (2 tsp) instant yeast, 10 g (2 tsp) fine kosher salt, 30 g (2 tbsp) sugar, 60 g (4 tbsp) unsalted butter (cold), 360 ml (1½ cups) warm water (43°C/110°F), 30 ml (2 tbsp) olive oil. The cornmeal adds flavor and texture; do not omit entirely. If using Morton salt, reduce to 1 tsp.
Italian sausage (primary protein): 600 g (1.3 lb) sweet or spicy Italian sausage, casings removed. Browning first concentrates flavor and removes excess moisture.
Cheese (mozzarella + optional aged cheese): 600 g (5 cups) low-moisture shredded mozzarella, 60 g (¾ cup) grated Pecorino Romano for finishing. Low-moisture mozzarella melts reliably; fresh ball mozzarella is too wet unless well-drained.
Sauce: 900 g (about 3½ cups) crushed tomatoes, 2 tbsp tomato paste, 1 tsp sugar, 2 cloves garlic minced, 1 tsp dried oregano, ½ tsp red pepper flakes (optional), 15 ml (1 tbsp) olive oil, salt and pepper to taste. A slightly thickened sauce prevents watery filling.
Vegetables & aromatics (optional): 1 medium onion diced, 1 green bell pepper thinly sliced. Sauté briefly; they add sweetness and texture.
Olive oil/butter for pan: 30 g (2 tbsp) unsalted butter plus 15 ml (1 tbsp) olive oil to coat the pan for flavor and browning.
Substitutions: Use a 1:1 gluten-free flour blend plus ½ tsp xanthan gum for a gluten-free crust; texture will be slightly different. For a lower-fat version, use turkey Italian sausage but expect less savory succulence.

Essential Equipment

10-inch (25 cm) deep-dish pan or a 10-inch cast-iron skillet (preferred) — a smaller pan will overflow, a larger pan will make the crust too thin.
Digital kitchen scale for accurate flour and cheese measures.
Stand mixer with dough hook (optional) — you can mix by hand and finish with 6–8 minutes of kneading.
Instant-read thermometer to check dough temperature and final pizza doneness.
Small sauté pan for browning sausage and vegetables.
Bench scraper and rolling pin or your hands to press dough into the pan.
If you don’t have a cast-iron, use a deep cake pan (10-inch) as a substitute and follow the same bake time.

Step-by-Step Instructions

Prep Time: 45 minutes | Cook Time: 45 minutes | Inactive Time: 1 hour | Total Time: 2 hours 30 minutes | Servings: 8 slices

Step 1: Make the dough

Combine 500 g (4 cups) all-purpose flour, 60 g (½ cup) fine yellow cornmeal, 10 g (2 tsp) instant yeast, 10 g (2 tsp) kosher salt, and 30 g (2 tbsp) sugar in a large bowl. Add 360 ml (1½ cups) warm water (43°C/110°F), 30 ml (2 tbsp) olive oil, and 60 g (4 tbsp) cold unsalted butter cut into pieces; mix until a shaggy dough forms, about 2 minutes of stirring. Do not overmix — stop as soon as no dry flour is visible.

Step 2: Knead and rise

Knead the dough in a stand mixer with a dough hook for 6–8 minutes on medium-low, or by hand for 8–10 minutes, until smooth and slightly tacky. Transfer to a lightly oiled bowl, cover, and let rise in a warm spot until doubled, about 45–60 minutes. The dough should spring back slowly when pressed.

Step 3: Brown the sausage and aromatics

While the dough rises, heat a sauté pan over medium-high. Crumble and brown 600 g (1.3 lb) Italian sausage for 6–8 minutes until deeply browned and no pink remains; transfer to paper towels to drain. Sauté 1 medium diced onion and 1 green bell pepper for 4–5 minutes until softened and fragrant. This reduces water and concentrates flavor.

Step 4: Prepare the sauce

In the same pan, lower heat to medium, add 15 ml (1 tbsp) olive oil and 2 minced garlic cloves; cook until fragrant, about 30 seconds. Stir in 900 g (about 3½ cups) crushed tomatoes, 2 tbsp tomato paste, 1 tsp sugar, 1 tsp dried oregano, ½ tsp red pepper flakes, and salt to taste. Simmer gently for 10 minutes to thicken slightly, stirring occasionally.

Step 5: Preheat oven and prepare pan

Preheat oven to 220°C (425°F). Butter a 10-inch (25 cm) cast-iron skillet with 30 g (2 tbsp) unsalted butter and 15 ml (1 tbsp) olive oil, making sure the bottom and sides are well coated to encourage browning. Roll or press the dough into a disk about 12 inches (30 cm) across and drape into the pan with a 2 cm (¾ inch) lip.

Step 6: Assemble the pizza (cheese first)

Layer 450 g (3½ cups) shredded low-moisture mozzarella into the dough-lined pan so it covers the bottom evenly. Sprinkle half the browned sausage and sautéed vegetables over the cheese. Layering cheese under sauce helps prevent burning and keeps moisture in the filling.

Step 7: Add sauce and finish

Spoon the tomato sauce over the cheese and sausage, spreading to the edges. Top with the remaining 150 g (1¼ cups) shredded mozzarella and 60 g (¾ cup) grated Pecorino Romano. Lightly brush the exposed dough edge with olive oil.

Step 8: Bake until done

Bake at 220°C (425°F) for 30–35 minutes until the crust is deep golden brown and the sauce is bubbling; check after 25 minutes to avoid over-browning. If the crust is browning too fast, tent loosely with foil. The internal temperature near the center should reach 74°C (165°F) if checked with a thermometer.

Step 9: Rest and slice

Remove pizza and let rest for 10 minutes to set the filling, then run a knife around the edge and invert onto a cutting board or slice directly in the pan. Cut into 8 slices and serve warm.

Expert Tips & Pro Techniques

Use cold butter in the dough: Cutting cold butter into the flour gives a flaky, layered crumb in the crust similar to a shortbread edge.
Common mistake — soggy center: If your center is watery, the two main causes are undercooked sausage (too moist) or a wet sauce. Brown the sausage well and simmer the sauce until it’s thickened.
Cast-iron advantage: Cast-iron conducts heat evenly and creates a superior crust. If using a non-stick pan, reduce oven temp by 10°C (50°F) and watch for doneness.
Make-ahead: Dough can be made up to 24 hours in advance and refrigerated. Bring to room temperature for 45 minutes before shaping. Sausage and sauce can be made 2 days ahead and refrigerated.
Professional-to-home trick: Finish the pizza under the broiler for 60–90 seconds to get a blistered top, but watch closely — it moves from perfect to burnt quickly.
Scaling tip: If you double the recipe, use two pans rather than a single very large one to preserve crust height and bake consistency.

Storage & Reheating

Refrigerator: Cool completely, then store slices in an airtight container or wrapped tightly in foil for up to 4 days. Reheat slices in a 175°C (350°F) oven for 10–12 minutes until warmed through and crust is crisp.
Freezer: You can freeze whole baked pizza or individual slices for up to 2 months. Wrap tightly in plastic and then foil. Thaw overnight in the fridge before reheating.
Reheating: Reheat in a 175°C (350°F) oven for 10–15 minutes for slices, or 20–25 minutes for a whole pie. Avoid microwaving — it will make the crust soggy.

Variations & Substitutions

Spicy Sausage & Peppers: Use spicy Italian sausage, add roasted red peppers (150 g/1 cup), and increase red pepper flakes to 1 tsp. Everything else stays the same.
Vegetarian Version: Replace sausage with 400 g (about 4 cups) sautéed mushrooms and roasted eggplant; add 120 g (1 cup) cooked lentils for texture. Baking time is unchanged.
Gluten-Free Crust: Replace the 500 g all-purpose flour with 600 g (approx) 1:1 gluten-free flour blend and add ½ tsp xanthan gum. Dough will be stickier; press into pan rather than roll. Bake an additional 3–5 minutes if needed.
Pepperoni Mix: Add 150 g (5 oz) sliced pepperoni on top of the sauce before the last 10 minutes of baking for crisp edges. Keep assembly and bake temps the same.
Lower-Fat Option: Use 600 g (1.3 lb) turkey Italian sausage and reduce cheese by 20% for fewer calories; expect slightly less richness.

Serving Suggestions & Pairings

Serve with a crisp green salad and a tangy vinaigrette to cut the richness. You might try pairing with autumn kale salad for a seasonal contrast.
Roasted potatoes or garlic-roasted broccoli make a hearty side and soak up any extra sauce.
Beverages: A medium-bodied lager or a fruity Chianti complements the tomato and sausage flavors.
Garnish: Finish with a sprinkle of chopped fresh basil or a dusting of Pecorino Romano for brightness and salt.

Serve leftover slices with warm apple butter on the side for a sweet-savory finish at brunch.

Frequently Asked Questions

Q: Why did my deep dish pizza turn out soggy in the middle?
A: Sogginess usually comes from undercooked sauce or too-wet toppings. Brown sausage and sauté vegetables well, and simmer the sauce until slightly reduced. Also make sure the oven is fully preheated to 220°C (425°F) before baking.

Q: Can I make this without eggs?
A: Yes — this dough contains no eggs. If you meant swapping eggs in toppings or fillings, there’s no egg required in the recipe.

Q: Can I double this recipe to feed a crowd?
A: Yes. Make two 10-inch pizzas rather than a single oversized one to keep crust height and bake times consistent.

Q: Can I prepare the pizza the night before?
A: You can refrigerate the assembled pizza overnight, but it may be slightly softer in the center. For best texture, par-bake the crust for 8–10 minutes, cool, then assemble and finish baking before serving.

Q: How long does this keep in the fridge?
A: Stored in an airtight container, pizza keeps 3–4 days in the refrigerator.

Q: Can I use fresh mozzarella instead of low-moisture mozzarella?
A: You can, but drain and pat the fresh mozzarella thoroughly; otherwise it will release moisture during baking and can make the filling watery.

Q: What’s the best pan to use if I don’t have cast iron?
A: Use a 10-inch deep cake pan as a substitute. The crust will brown differently, so watch the bake and tent with foil if needed.
