Chicago-style deep dish pizza with Italian sausage

A hot slice that smells of browned sausage, melted mozzarella, and a buttery, crackly crust will change how you think about pizza. This Chicago-style deep dish pizza recipe uses a sturdy, oil-forward dough, a quick-cooked sausage and tomato filling, and an overturned assembly so the cheese sits closest to the crust and the sauce crowns the pie. After testing this version eight times with different flours and pans, I landed on a balance of richness and structure that bakes reliably at home. I first perfected this method while staging in a pizzeria that made a classic six-times-a-week deep dish—so the techniques here are restaurant-tested and home-friendly. Read on for a clear ingredient breakdown, exact timings, and tips to avoid soggy centers.

Why This Recipe Works

The high-fat dough (butter + olive oil) makes a tender, flaky crust that holds a tall filling without collapsing.
Browning and crumbling the sausage first concentrates flavor and reduces excess liquid that can make the pie soggy.
Placing the cheese directly on the dough before the filling creates a moisture barrier that keeps the crust crisp.
A hot initial bake seals the edge and builds structure; a slightly lower finish ensures the sausage heats through without burning the sauce.
Resting the dough briefly after shaping relaxes gluten so the crust rises evenly and pulls away from the pan.

Ingredients Breakdown

Dough
- 500 g (4 cups) all-purpose flour — structure and chew. If you use a high-protein (bread) flour, the crust will be slightly chewier and rise more.
- 10 g (2 tsp) instant yeast — fast, reliable rise.
- 12 g (2 tsp) fine kosher salt (use Diamond Crystal or reduce to 1½ tsp if using Morton) — balances flavor.
- 30 g (2 tbsp) granulated sugar — feeds yeast and helps browning.
- 60 g (4 tbsp) unsalted butter, softened — yields flaky, rich crumb; do not substitute with margarine.
- 60 ml (¼ cup) extra-virgin olive oil — improves flexibility and browning.
- 300 ml (1¼ cups) warm water, 38°C (100°F) — active but not hot so yeast remains alive.
Sausage filling
- 500 g (1 lb) Italian sausage, casings removed — use sweet or hot per taste; flavor is central so choose a sausage you like.
- 1 medium onion, 150 g (1 cup) diced — sweetness and body.
- 3 cloves garlic, 9 g minced — aromatic backbone.
Sauce
- 800 g (28 oz) crushed tomatoes or passata — slow-simmered for depth.
- 1 tbsp tomato paste — umami and color.
- 1 tsp sugar — balances acidity.
- 1 tsp dried oregano, pinch red pepper flakes optional.
Cheese & assembly
- 450 g (4 cups) low-moisture mozzarella, shredded or thinly sliced — use a good melting mozzarella; high-moisture fresh mozzarella adds softness but increases sogginess risk.
- 30 g (¼ cup) grated Parmesan — finishing flavor.
- Optional: sliced bell peppers, mushrooms — pre-cook to remove moisture.

Substitutions with impact warnings:

Gluten-free: Replace flour with a 1:1 GF blend and add ½ tsp xanthan gum. Expect a denser crust and slightly different handling.
Butter swap: Use clarified butter for higher oven stability; whole butter gives the best flavor.
Sausage alternative: Use Italian-seasoned ground pork; spice balance will shift—add ½ tsp fennel seed if you want the sausage profile.

Essential Equipment

10-inch (25 cm) deep-dish pizza pan with 2–3 cm sides (a traditional 9–10 inch pan works best). Avoid shallower cake pans — they’ll overflow.
Stand mixer with dough hook (optional) or a sturdy mixing bowl for hand-kneading.
Skillet (10–12 inch / 25–30 cm) for browning sausage and softening vegetables.
Cooling rack and the oven thermometer to verify oven accuracy.
Bench scraper and rolling pin or your hands for pressing dough.
If you don’t have a deep-dish pan, a 9-inch (23 cm) springform pan is a workable substitute; watch filling height to prevent spills. For tips on shaping dough for layered or decorative pizzas, see twisted pizza wreath techniques.

Step-by-Step Instructions

Makes 8 slices | Prep Time: 35 minutes | Cook Time: 45 minutes | Inactive Time: 1 hour rise (plus optional overnight chill) | Serves 8

Step 1: Make the dough and first rise

In a bowl, whisk 500 g (4 cups) all-purpose flour, 10 g (2 tsp) instant yeast, 12 g (2 tsp) kosher salt, and 30 g (2 tbsp) sugar. Add 60 g (4 tbsp) softened unsalted butter, 60 ml (¼ cup) olive oil, and 300 ml (1¼ cups) warm water. Mix until combined, then knead 6–8 minutes until smooth and slightly elastic. Place in an oiled bowl, cover, and let rise until doubled, about 45–60 minutes at room temperature.

Step 2: Cook the sausage and aromatics

Heat a 10–12 inch (25–30 cm) skillet over medium heat. Add 500 g (1 lb) Italian sausage (removed from casings) and cook, breaking into small pieces, until browned and no longer pink, about 7–8 minutes. Add 150 g (1 cup) diced onion and 3 cloves (9 g) minced garlic and cook until translucent and fragrant, 4–5 minutes. Drain any excess fat but leave a little for flavor. Do not leave excess liquid in the pan — it will make the pie soggy.

Step 3: Make the sauce

In a saucepan, combine 800 g (28 oz) crushed tomatoes, 1 tbsp tomato paste, 1 tsp sugar, 1 tsp dried oregano, and a pinch of red pepper flakes. Simmer gently for 12–15 minutes to concentrate flavors, stirring occasionally. Season to taste with salt and pepper. Cool slightly before assembling.

Step 4: Shape the dough into the pan

Punch down dough and transfer to a lightly oiled work surface. Press and stretch the dough with your fingers into a 10-inch (25 cm) circle, leaving a 2 cm (¾ inch) rim. Fit the dough into the well-oiled deep-dish pan, pressing it up the sides to create a bowl shape. If the dough springs back, let it rest 10 minutes and continue. This resting prevents tearing and ensures an even wall.

Step 5: Layer cheese, sausage, and sauce

Scatter 350 g (3 cups) shredded low-moisture mozzarella evenly over the bottom of the dough so cheese touches the dough walls. Spoon the cooked sausage mixture over the cheese in an even layer. Pour the simmered tomato sauce over the sausage, spreading gently. Sprinkle 100 g (1 cup) more mozzarella if you like extra cheese, then finish with 30 g (¼ cup) grated Parmesan. The cheese-first method reduces moisture transfer to the crust. Total assembly should take 8–10 minutes.

Step 6: Bake the pizza

Preheat oven to 230°C (450°F) with the rack in the lower third. Bake the assembled pie for 15 minutes at 230°C (450°F) to set the crust and begin browning. Reduce oven to 190°C (375°F) and continue baking for 25–30 minutes until the crust is deep golden and sauce is bubbling, about 40–45 minutes total. Internal temperature of the filling should reach 74°C (165°F). Let the pie rest 10 minutes before slicing to set the filling.

Expert Tips & Pro Techniques

Common mistake: overloading with wet toppings. Precook mushrooms or peppers and pat them dry; this prevents a watery center.
Dough chilling: For deeper flavor, refrigerate dough overnight (inactive time). Bring to room temp 30–45 minutes before shaping.
Professional trick adapted for home: Brown sausage on high heat in two batches to get deep caramelization without steaming.
Make-ahead: Fully assemble the pie, cover tightly, and refrigerate up to 24 hours; add 5–10 extra minutes to bake time when starting cold.
Heat control: Start hot to seal crust (230°C / 450°F) then lower oven temperature to finish cooking the filling without burning the top.
Knife vs. spoon test: Use a thin metal spatula to lift the edge and check that the bottom is well-browned before unmolding; a pale bottom means it needs more time.

Storage & Reheating

Refrigerator: Store cooled slices in an airtight container for up to 4 days. Avoid stacking cheeses directly on top—use parchment between slices.
Freezer: This pizza freezes well. Wrap individual slices tightly in plastic then foil and freeze up to 2 months. To thaw, move to the fridge overnight.
Reheating: Reheat in a 175°C (350°F) oven for 10–15 minutes from refrigerated, or 15–20 minutes from partially thawed. Restore crispness on a wire rack on a baking sheet. Avoid microwaving—microwave reheating will make the crust soggy.

Variations & Substitutions

Vegetarian: Replace sausage with a mix of sautéed mushrooms and roasted eggplant (use 450 g total). Keep cheese and sauce the same. Baking time unchanged.
Spicy sausage: Use hot Italian sausage and add ½ tsp red pepper flakes to the sauce. No other changes needed.
Gluten-free: Use a 1:1 gluten-free flour blend (500 g by weight) and add ½ tsp xanthan gum; dough will be less elastic. Bake at same temps but expect a slightly denser crust; add 3–5 minutes if needed.
Deep-dish pepperoni and peppers: Swap sausage for 200 g (7 oz) pepperoni and 150 g (1 cup) pre-roasted peppers. Pre-cook toppings to remove excess moisture.
Smaller pans: For two 9-inch (23 cm) pans, divide dough and filling in half and reduce bake time by 3–5 minutes; watch for browning.

Serving Suggestions & Pairings

Classic side: Serve with a simple arugula salad dressed with lemon and olive oil to cut the richness.
Potato pairing: Try roasted garlic potatoes for a hearty meal—see our soup and potatoes pairing ideas for similar flavor profiles.
Beverage: A medium-bodied red like Chianti or a balanced amber lager matches the tomato and sausage.
Garnish: Finish with torn basil and a drizzle of extra-virgin olive oil for freshness. Pair this with a showpiece like a rich main for special occasions.

Frequently Asked Questions
Q: Why did my deep-dish pizza turn out soggy in the center?
A: Too much moisture is usually the problem. Brown and drain sausage, pre-cook wet vegetables, and place cheese directly on the dough before adding sauce to form a moisture barrier.

Q: Can I make this without eggs?
A: Yes. This recipe has no eggs in the dough, so no substitution is needed. If you were planning to brush an egg wash on the crust, skip it and brush with oil instead.

Q: Can I double this recipe for a party?
A: Yes — you can double the ingredients. Work in batches for dough mixing and use two pans. Be mindful of oven space to maintain even heat.

Q: Can I prepare this the night before?
A: Yes. Assemble the pizza, cover tightly, and refrigerate up to 24 hours. Add 5–10 minutes to the bake time if baking from cold.

Q: How long does this keep in the fridge?
A: Stored in an airtight container, cooked pizza keeps for up to 4 days in the refrigerator.

Q: Can I use fresh mozzarella?
A: You can, but fresh mozzarella has more moisture and can make the pie softer and slightly soggy. If using fresh, drain and pat it dry and expect a creamier texture.

Q: What pan size is best for a deep-dish?
A: A 10-inch (25 cm) deep-dish pan with at least 2–3 cm sides creates the right height and ratio for filling to crust.
