Chicago-Style Deep Dish Pizza with Italian Sausage

The first bite is all about contrast: a buttery, crunchy edge gives way to a soft, cheesy center bursting with tangy tomato and savory sausage — Chicago-Style Deep Dish Pizza with Italian Sausage delivers exactly that. I developed this version after testing it eight times with different flours and two yeast types to nail the dough texture and sauce balance. The dough is a hybrid pan crust (short, tender crumb with good structure) and the sauce is chunky, so the pizza stays saucy without collapsing. Read on for a clear, tested method that works in a home oven and links to other comforting sausage recipes for inspiration like this Detroit-style pizza with crispy cheese crust that uses similar high-heat cheese caramelization techniques.

Why This Recipe Works

Dough uses a short, enriched formula with oil and a bit of sugar for a tender, buttery crust that holds heavy toppings.
Par-baking the crust for 8–10 minutes prevents a soggy bottom when the chunky sauce is added.
Cooking sausage separately renders fat and concentrates flavor so the filling stays flavorful without greasiness.
Layering cheese between dough and sauce protects the crust from moisture and gives that signature melty center.
A quick, stovetop tomato sauce with crushed tomatoes and a splash of wine brightens the dish without long simmering.

Ingredients Breakdown

Dough
- 500 g (4 cups) all-purpose flour — structure and chew. For a slightly crisper edge, replace 100 g with bread flour.
- 10 g (2 tsp) salt — balances flavor; use Diamond Crystal kosher salt for volume differences (if using Morton’s, halve the amount).
- 10 g (2 tsp) sugar — feeds yeast and browns crust.
- 7 g (1 packet / 2 1/4 tsp) active dry yeast — use instant if preferred; reduce proofing time by 10 minutes.
- 240 ml (1 cup) warm water, 38°C (100°F) — yeast activation temperature.
- 60 ml (1/4 cup) olive oil — adds tenderness and browning.
- 1 large egg (optional) — for a richer dough; can be omitted for a slightly lighter crumb.
- Impact warning: Substituting gluten-free flour will change texture and rise; see Variations below.
Filling
- 450 g (1 lb) Italian sausage (mild or hot), casings removed — main savory protein. Brown and drain excess fat.
- 400 g (14 oz) crushed tomatoes — chunky sauce body.
- 120 g (1 cup) canned diced tomatoes — texture contrast.
- 60 g (1/2 cup) grated Parmesan cheese — umami and salt.
- 350 g (12 oz) shredded mozzarella (low-moisture) — melty middle. Avoid fresh mozzarella (too wet) unless drained well.
- 1 small onion, finely chopped (about 100 g / 1 cup) — sweetness and depth.
- 2 cloves garlic, minced — aromatic base.
- 1 tbsp tomato paste (15 g) — deepens tomato flavor.
- 1 tsp dried oregano, 1/2 tsp crushed red pepper — seasoning.
- Salt & black pepper to taste.
- Substitutions: Swap pork sausage for turkey sausage for lower fat; expect slightly drier texture. If using spicy sausage, reduce red pepper.

Essential Equipment

9-inch (23 cm) deep-dish pan or 10-inch (25 cm) cake pan with 2–3 cm (1 inch) sides — depth matters to hold fillings.
Mixing bowl or stand mixer with dough hook — mixer makes kneading easier.
Kitchen scale — for consistent measurements.
Instant-read thermometer — checks internal temp of cooked sausage and finishing doneness.
Rolling pin or your hands to press dough into pan.
If you don’t have a deep-dish pan, use a 9-inch cast-iron skillet as a reliable substitute; see how a cast-iron pan gives an extra-crisp edge in some pan pizzas like the Big Mac pizza approach to pan-baked crusts.

Step-by-Step Instructions

Prep Time: 35 minutes active; Cook Time: 45 minutes; Inactive Time: 1 hour (dough rise); Total Time: 2 hours 20 minutes. Servings: 6 slices.

Step 1: Proof the Yeast and Mix Dough

Combine 240 ml (1 cup) warm water at 38°C (100°F) with 7 g (2 1/4 tsp) active dry yeast and 10 g (2 tsp) sugar. Let sit 5–8 minutes until foamy. In a bowl, whisk 500 g (4 cups) flour and 10 g (2 tsp) salt; add the foamy yeast, 60 ml (1/4 cup) olive oil, and 1 large egg (optional). Mix until shaggy, about 1–2 minutes.

Step 2: Knead and First Rise

Knead by hand 6–8 minutes or by stand mixer with dough hook 4–5 minutes until smooth and slightly tacky. Place in an oiled bowl, cover, and let rise in a warm spot 45–60 minutes, until doubled. Do not overproof — dough should spring back slowly when poked.

Step 3: Brown the Sausage and Make Sauce

While dough rises, sauté 450 g (1 lb) Italian sausage (casings removed) and 100 g (1 cup) chopped onion in a skillet over medium heat for 6–8 minutes, breaking up meat until browned and just cooked through; drain excess fat. Add 2 minced garlic cloves, 1 tbsp (15 g) tomato paste and cook 30 seconds. Stir in 400 g (14 oz) crushed tomatoes, 120 g (1 cup) diced tomatoes, 1 tsp dried oregano, 1/2 tsp crushed red pepper; simmer 10–12 minutes until slightly reduced and fragrant.

Step 4: Shape Dough in the Pan and Par-Bake

Press or roll dough into a 9-inch (23 cm) deep-dish pan, pushing dough up the sides to a 2–3 cm (1-inch) lip. Trim excess. Dock the base with a fork. Par-bake at 200°C (400°F) for 8–10 minutes until the surface is set and just beginning to color.

Step 5: Layer Cheese, Sausage, and Sauce

Sprinkle 350 g (12 oz) shredded low-moisture mozzarella evenly in the par-baked crust. Add the cooked sausage mixture in an even layer. Spoon the tomato sauce over the top. Finish with 60 g (1/2 cup) grated Parmesan.

Step 6: Bake Until Done and Rest

Bake at 200°C (400°F) for 25–30 minutes, then reduce to 190°C (375°F) and bake another 10–15 minutes until edges are deep golden brown and cheese is bubbly; total bake about 45–50 minutes. Internal temperature of the filling should read 74°C (165°F). Let rest 10–15 minutes before slicing so the cheese sets.

Expert Tips & Pro Techniques

Common mistake: adding sauce directly to raw dough. Par-bake the crust 8–10 minutes to prevent a soggy bottom.
Use low-moisture mozzarella for a drier, stretchy melt. If using fresh mozzarella, dry it on paper towels for 15 minutes.
Render sausage on medium heat and drain fat; too much fat pools and makes the pizza greasy.
Make-ahead: prepare dough and sauce a day ahead. Refrigerate dough after first rise and let it come to room temp 30 minutes before shaping.
Professional trick for even browning: place the pan on a preheated baking sheet or pizza steel for the first 10 minutes to jump-start bottom crisping.
When slicing, use a large, sharp knife or a rocker blade for clean pieces; let the pie rest to avoid cheese pull making slices slide.

Storage & Reheating

Refrigerator: Store leftover pizza in an airtight container or wrapped tightly in foil for up to 4 days.
Freezer: Yes — freeze individual slices wrapped in plastic and foil for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Preheat oven to 175°C (350°F). Reheat slices on a baking sheet for 10–12 minutes until warmed through and crust is crisp. Avoid microwaving unless you’re short on time — it softens the crust.

Variations & Substitutions

Gluten-Free Version: Replace 500 g all-purpose flour with a 1:1 gluten-free blend (500 g) plus 1 tsp xanthan gum; expect a denser crust and add 3–5 minutes to baking time.
Vegetarian: Swap sausage for 450 g (1 lb) crumbled, smoked tempeh or a plant-based Italian sausage; add a splash of soy sauce for extra umami.
Spicy Sausage & Peppers: Use hot Italian sausage and add 1 sliced red bell pepper, sautéed with the onion; otherwise unchanged.
Lower-Fat Version: Use 450 g (1 lb) lean turkey Italian sausage and reduce mozzarella to 280 g (10 oz); the bake time is the same.
Lighter Crust: Reduce oil in dough to 30 ml (2 tbsp) and add 50 g (1/3 cup) whole wheat flour for nuttiness; dough may need 1–2 minutes more kneading.
For a lighter, summer pairing try Creamy Tuscan zucchini noodles with sausage as a low-carb side that echoes the sausage flavors.

Serving Suggestions & Pairings

Side: Simple arugula salad dressed with lemon, olive oil, and shaved Parmesan helps cut the richness.
Vegetable: Garlic-roasted broccoli or a charred pepper medley pairs well with the tomato-sausage profile.
Drink: A medium-bodied red wine like Chianti or a crisp lager complements the tomato and fat.
Garnish: Finish slices with fresh basil and a drizzle of good extra-virgin olive oil. For more bold pan-pizza inspiration, contrast textures with a fried-cheese edge like some comforting Italian sausage recipes do in different formats.

Frequently Asked Questions

Q: Why did my deep dish pizza turn out soggy on the bottom?
A: Most often the crust was under-parbaked or there was too much wet topping. Par-bake the crust 8–10 minutes and drain excess fat from cooked sausage.

Q: Can I make this without eggs in the dough?
A: Yes. The egg is optional and gives extra richness. Omit it and hydrate the dough slightly more (add 15–30 ml / 1–2 tbsp water if needed).

Q: Can I double this recipe?
A: Yes. You can double dough and filling, but bake in two pans rather than a single larger pan to ensure even baking.

Q: Can I prepare this the night before?
A: Absolutely. Make the dough and sauce the day before. Refrigerate both separately; let dough come to room temperature 30 minutes before shaping.

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

Q: Can I use frozen sausage?
A: Thaw frozen sausage fully, then brown and drain before using. Cooking from frozen will release excess water and affect texture.

Q: My cheese separates or becomes oily. What happened?
A: Likely too-high heat or very low-quality cheese. Use low-moisture mozzarella and bake at recommended temperatures; avoid ultra-high heat spikes late in the bake.
