Chicago-style deep dish pizza with Italian Sausage

Hot, buttery crust and a mountain of melting cheese greet every forkful of Chicago-style deep dish pizza. This is the kind of pie that eats like a meal: a thick, flaky crust, a layer of cheese, savory Italian sausage, and chunky tomato sauce on top. After testing this recipe 10 times with different flours and pan sizes, I settled on a dough and assembly method that yields a reliably tender, buttery crust and no-soggy center. I developed and refined techniques during years cooking in busy pizzerias, and I’ll share the timing and sensory cues that mattered most. Read on for precise measurements, step-by-step photos, and pro tips so your first pie looks and tastes restaurant-close at home. If you like exploring different crusts, compare this to a thinner style in our guide to classic Italian pizza.

Why This Recipe Works

Butter + oil in the dough creates a flaky, shortcrust-like texture that still has good structure when baked.
Layering cheese under the toppings prevents the crust from getting soggy from the tomato sauce.
Browning the sausage first concentrates flavor and removes excess fat, keeping the pie tidy.
A hot oven and preheated pan produce crisp edges while the interior stays tender.
Resting the dough relaxes gluten so the crust rolls easily and doesn’t spring back.

Ingredients Breakdown

Dough
- 500 g (4 cups) all-purpose flour — structure and chew. Substituting bread flour increases chewiness; reduce water by 15 ml (1 tbsp).
- 7 g (1 packet / 2 1/4 tsp) instant yeast — reliable rise without proofing time. If using active dry yeast, proof in 60 ml (1/4 cup) warm water first.
- 10 g (2 tsp) fine salt — flavor. Use Diamond Crystal kosher salt for volume; if using Morton, halve the weight.
- 12 g (2 tbsp) sugar — feeds yeast and browns crust.
- 240 ml (1 cup) warm water (38–43°C / 100–110°F) — hydrates dough.
- 85 g (6 tbsp) unsalted butter, melted — gives flaky, tender texture. You can swap half with olive oil for a slightly crisper crust.
- 30 ml (2 tbsp) olive oil — keeps dough supple and helps pan release.
Filling & Sauce
- 300 g (10–11 oz) whole-milk mozzarella, shredded — melts and creates a barrier. Part-skim will be less gooey.
- 450 g (1 lb) Italian sausage (sweet or spicy), casings removed — main savory protein. Use high-quality sausage for the best flavor; if using bulk sausage, taste for seasoning.
- 800 g (28 oz) canned crushed tomatoes — chunky, bright sauce. You can use San Marzano-style for sweetness.
- 1 small yellow onion, finely diced (120 g / 1 cup) — sweated into sauce for sweetness.
- 3 cloves garlic, minced (9 g) — aromatic lift.
- 15 g (1 tbsp) tomato paste — deepens flavor.
- 5 g (1 tsp) dried oregano and 3 g (1/2 tsp) crushed red pepper — seasoning. Fresh basil can be stirred in at the end.
Finishing
- 30 g (1/4 cup) grated Parmesan — salty finish.
- Extra butter to grease the pan — encourages flaking and browning.

Substitution warnings: You can replace all-purpose flour with a 1:1 gluten-free blend, but add 1/2 tsp xanthan gum and expect slightly different texture. Using pre-shredded cheese often contains anti-caking agents that can impede melt; shred your own for best results.

Essential Equipment

10-inch (25 cm) deep-dish pan or a 9–10 inch springform pan with 2–3 inch (5–7 cm) sides — the volume of dough and filling is calibrated to 10 inches; smaller pans will overflow.
Digital scale — weigh dry ingredients for consistency.
Stand mixer with dough hook (optional) — you can knead by hand for 8–10 minutes instead.
Skillet for browning sausage and cooking sauce.
Instant-read thermometer — check internal temps and water temperature.
Rolling pin or hands for pressing dough into the pan. For a flaky edge, use a small offset spatula to tuck the dough.

If you don’t have a deep-dish pan, a well-greased 9-inch cast-iron skillet works as a great substitute.

Step-by-Step Instructions

Prep Time: 35 minutes | Cook Time: 45 minutes | Inactive Time: 1 hour (dough rest) | Total Time: 2 hours 20 minutes | Servings: 8 slices

Step 1: Make the dough

In a bowl or stand mixer, combine 500 g (4 cups) all-purpose flour, 7 g (2 1/4 tsp) instant yeast, 10 g (2 tsp) salt, and 12 g (2 tbsp) sugar. Add 240 ml (1 cup) warm water and 30 ml (2 tbsp) olive oil, then stir to form a shaggy dough. Knead 6–8 minutes by mixer or 8–10 minutes by hand until smooth and elastic; dough should feel slightly tacky, not sticky. Transfer to a lightly oiled bowl and let rest, covered, for 1 hour at room temperature until roughly doubled.

Step 2: Brown the sausage and build the sauce

Heat a skillet over medium-high and cook 450 g (1 lb) Italian sausage, breaking it into small pieces; sauté for 6–8 minutes until nicely browned and no longer pink. Remove excess fat, leaving about 1 tbsp to sweat onions. Sauté 1 small diced onion for 4–5 minutes until translucent, add 3 minced garlic cloves and cook 30 seconds. Stir in 15 g (1 tbsp) tomato paste and cook 1 minute, then add 800 g (28 oz) crushed tomatoes, oregano, and salt to taste. Simmer gently for 10–12 minutes until slightly thickened and fragrant.

Step 3: Prepare the pan and assemble the layers

Preheat the oven to 220°C (425°F). Generously butter a 10-inch deep-dish pan. On a lightly floured surface, roll or stretch dough into a 30 cm (12-inch) disk to allow an overhang. Press dough into the pan so it covers bottom and sides with a 1–2 cm (1/2–1 inch) rim. Don’t overwork the dough — press gently to keep the flaky texture. Sprinkle 300 g (10–11 oz) shredded mozzarella in an even layer over the dough.

Step 4: Add sausage and sauce

Spread the browned sausage evenly over the cheese. Spoon the tomato sauce over the sausage in an even layer, smoothing with the back of a spoon. Sprinkle 30 g (1/4 cup) grated Parmesan over the top. Fold any excess dough inward and crimp the edge for a neat rim. Let the assembled pie rest 10 minutes while the oven reaches full temperature.

Step 5: Bake and finish

Place the pan on the center rack and bake at 220°C (425°F) for 25 minutes, then lower oven to 190°C (375°F) and bake an additional 15–20 minutes until the crust is deep golden and bubbling, about 40–45 minutes total. The internal temperature near the center should reach 74°C (165°F). Remove and cool 10–15 minutes before slicing to let the filling set.

Step 6: Slice and serve

Run a thin knife around the pan edge to release, then slice into 8 pieces. Serve warm with extra grated Parmesan and torn basil. Leftovers reheat well (see Storage & Reheating).

Expert Tips & Pro Techniques

Use cold butter melted into the dough rather than all oil to get a short, flaky crumb that still holds up to sauce.
Common mistake: overfilling the pan. If your crust looks too thin on the sides, remove a small amount of dough rather than risk overflow.
For even browning, rotate the pan halfway through baking and watch the edges after the first 30 minutes.
Make-ahead: You can prepare the dough the day before. Refrigerate, covered, after the first 30 minutes of rise and bring to room temperature for 60–90 minutes before shaping.
Professional trick for less sogginess: Sprinkle a thin layer of grated Pecorino or Parmesan directly on the crust before the mozzarella; cheese forms a moisture barrier.
If you don’t have a scale: 1 cup all-purpose flour ≈ 125 g, 1 tbsp ≈ 12–15 g for grains/sugars; but weighing is more reliable.

Storage & Reheating

Refrigerator: Cool completely, then store slices in an airtight container for up to 4 days. Separate layers with parchment to avoid sticking.
Freezer: This pizza freezes well. Wrap individual slices tightly in plastic wrap and foil, or freeze the whole pie wrapped well for up to 3 months. Thaw in the fridge overnight.
Reheating: Reheat slices on a sheet pan in a 175°C (350°F) oven for 10–12 minutes until warmed through and the crust is crisp. Avoid the microwave for best texture.

Variations & Substitutions

Vegetarian: Omit sausage and add a mix of roasted mushrooms and bell peppers. Keep the same cheese and sauce quantities; roast vegetables for 20 minutes before adding.
Gluten-free: Replace 500 g all-purpose flour with 500 g (approx 4 cups) 1:1 GF flour blend plus 1/2 tsp xanthan gum. Let dough rest 30 minutes longer; bake time may increase 3–5 minutes.
Chicken sausage or plant-based sausage: Swap 450 g (1 lb) sausage directly; check seasoning and adjust salt. Cook plant-based sausage per package directions to remove excess moisture.
Extra-cheesy: Increase mozzarella to 400 g (14 oz) and add a 50 g (1/2 cup) blend of fontina or provolone for creaminess. Baking time is unchanged.
Thin-crust hybrid: Press dough thinner (about 6 mm / 1/4 inch) and use a 12-inch pan. Reduce bake time by 5–8 minutes and watch for browning.

Frequently Asked Questions

Q: Why did my crust turn out dense instead of flaky?
A: Dense crust often means the dough was overworked or the yeast was old. Knead until elastic but not gummy, and check that your yeast is active. Also be sure to let the dough rest for the full hour to relax gluten.

Q: Can I make this without eggs?
A: Yes — this recipe does not use eggs. The richness comes from butter and olive oil, so no substitution is needed.

Q: Can I double this recipe?
A: Yes. For two pies, double all ingredients and bake in two separate 10-inch pans. Do not try to bake two pies stacked in one pan or a much larger pan without recalculating dough volume.

Q: Can I prepare the pie the night before?
A: Yes. Assemble the pie, cover tightly, and refrigerate overnight. When ready to bake, let the pie sit at room temperature 30 minutes, then bake as directed; you may need an extra 5–8 minutes of baking.

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

Q: Why is my center soggy even after baking?
A: Sogginess can come from undercooked sauce or too much moisture from toppings. Brown the sausage well and drain excess fat, simmer the sauce to thicken, and place cheese directly on the crust before the sauce to form a barrier.

Q: Is it safe to use pre-shredded cheese?
A: It’s safe, but pre-shredded cheese often contains anti-caking agents that reduce melt quality. For the best texture, shred a block of mozzarella yourself.
