Chicago-style deep dish pizza with Italian sausage

Warm, buttery edges, a tall rim of golden crust, and a molten cheese river — this Chicago-style deep dish pizza is pure comfort. I include the primary technique that gives the crust its lift and crisp: pressing rich oil into the dough and starting the bake in a hot oven-lined pan. After testing this recipe 8 times with different flours and pans, this version delivered the most consistent flaky crust and even bake. I developed and refined the sauce during a season cooking in a busy pizzeria, where the sausage-to-sauce balance was nonnegotiable. The recipe below is scaled for a 10-inch pan and serves eight generously. Read on for exact measurements, timing, and pro tips so your first attempt won’t be your last — and if you love Italian sausage in other ways, try our creamy Italian sausage soup for a cozy soup-night companion.

Why this recipe works

The dough is a 60% hydration formula with oil folded in, which creates a tender, almost biscuit-like crumb that still holds up to heavy toppings.
Browning the sausage before layering removes excess fat and concentrates flavor without soggy pockets.
Building the pizza with cheese first, sausage next, and sauce on top protects the crust from steaming and keeps the edge crisp.
A quick pan-sear of the oiled dough rim before baking boosts crust color and creates that signature pan-seared bottom.
Using crushed tomatoes and a short simmer concentrates acidity without losing brightness.

Ingredients breakdown

Dough
- 500 g (4 cups) all-purpose flour — provides structure. You can use bread flour (500 g) for chewier texture, but the crust will be less tender.
- 7 g (2 1/4 tsp) instant yeast — one packet for predictable rise.
- 15 g (1 tbsp) granulated sugar — feeds yeast and browns crust.
- 10 g Diamond Crystal kosher salt (about 1 3/4 tsp) — if you use Morton’s, halve the amount because it’s denser.
- 300 ml (1 1/4 cups) warm water, 38°C (100°F) — hydrate the dough.
- 60 ml (1/4 cup) extra-virgin olive oil, plus 15 ml (1 tbsp) for pan — oil tenderizes and crisps the crust.
Sauce
- 800 g (28 oz) crushed San Marzano-style tomatoes — chunky texture stands up to baking.
- 2 tbsp (30 ml) extra-virgin olive oil — carries flavor.
- 3 garlic cloves, minced — aromatic backbone.
- 1 tsp dried oregano and 1/2 tsp crushed red pepper (optional).
- 1 tsp sugar — cuts acidity if needed.
- Salt and black pepper to taste.
Toppings
- 450 g (1 lb) bulk Italian sausage, casings removed — sweet or hot per preference. Browning removes excess moisture.
- 340 g (12 oz) low-moisture mozzarella, shredded — melts cleanly under sauce.
- 60 g (1/2 cup) finely grated Parmesan or Pecorino — savory finish.
- Optional: 1 medium green bell pepper and 1 small yellow onion, thinly sliced and sautéed until softened.
Notes on substitutions
- Dairy-free: replace mozzarella with a plant-based shred that melts well; texture will be slightly different.
- Vegetarian: swap sausage for a seasoned mushroom-and-walnut crumble; reduce sauté time by 2 minutes.
- If you must use frozen sausage, thaw thoroughly and pat dry to avoid a watery pizza.

Essential equipment

10-inch deep-dish pizza pan or 10-inch cast-iron skillet (deep-sided) — the pan size matters; smaller pans will overflow.
Stand mixer with dough hook (optional) — can be done by hand in a large bowl.
A digital scale for precise flour and water measurements.
Instant-read thermometer — check dough temperature and final doneness.
Bench scraper or sturdy spatula for pressing dough into the pan.
If you don’t have a deep-dish pan, a 10-inch straight-sided cake pan or a 10-inch cast-iron skillet works as a substitute; expect a slight change in bake time.

Step-by-step instructions

Prep time is about 30 minutes active (plus 1 hour proof). Cook time is 50–60 minutes. Inactive time (first dough rest) is 1 hour. Total time ~2 hours. Recipe makes 8 slices.

Step 1: Make the dough

Combine 500 g (4 cups) all-purpose flour, 7 g (2 1/4 tsp) instant yeast, 15 g (1 tbsp) sugar, and 10 g Diamond Crystal kosher salt in a bowl. Add 300 ml (1 1/4 cups) warm water and 60 ml (1/4 cup) olive oil; mix until just combined, about 1–2 minutes. Do not overmix — stop as soon as no dry flour is visible.

Step 2: Knead and first proof

Knead by hand 6–8 minutes or in a stand mixer 4–5 minutes until the dough is smooth and slightly tacky. The dough should reach about 24–26°C (75–79°F). Cover and let rest for 1 hour at room temperature, until roughly doubled.

Step 3: Prepare the sauce and toppings while dough rises

Heat 2 tbsp (30 ml) olive oil in a saucepan over medium heat, sauté 3 minced garlic cloves 30–45 seconds until fragrant, add 800 g (28 oz) crushed tomatoes, 1 tsp dried oregano, 1 tsp sugar, and salt to taste. Simmer gently 12–15 minutes until slightly thickened and bright. Brown 450 g (1 lb) Italian sausage in a skillet, breaking it into small pieces; cook 6–8 minutes until browned and no pink remains. Sauté peppers and onions 4–5 minutes until softened. Cool slightly.

Step 4: Shape and oil the pan

Preheat oven to 230°C (450°F) with a rack in the lower third. Brush the pan with 15 ml (1 tbsp) olive oil and warm it in the oven for 3 minutes — hot oil helps sear the dough bottom. Remove the pan with oven mitts.

Step 5: Press dough into the pan

Turn dough onto a lightly floured surface and press into a 25-cm (10-inch) disk. Lift and ease dough into the pan, pushing it up the sides to form a 2–3 cm (¾–1¼ in) rim; leave a slightly thicker edge for a buttery crust. Let rest 10 minutes.

Step 6: Layer cheese, sausage, and sauce

Scatter 340 g (12 oz) shredded low-moisture mozzarella evenly across the dough (this seals the crust). Top with the browned sausage and optional sautéed vegetables. Spoon the sauce over the toppings, roughly 1 1/2–2 cups (about 350–450 g), so the sauce sits on top. Sprinkle 60 g (1/2 cup) grated Parmesan.

Step 7: Bake

Bake at 230°C (450°F) for 30–35 minutes, then rotate the pan and reduce heat to 205°C (400°F); bake an additional 15–20 minutes until the crust is deep golden and cheese bubbles. Total bake time 45–55 minutes. The internal temperature should read 74°C (165°F) near the center.

Step 8: Rest and serve

Remove from oven and let rest 10 minutes to set the sauce and make slicing cleaner. Run a knife around the rim and transfer to a cutting board. Garnish with fresh basil if desired. Slice into 8 pieces and serve hot.

Expert Tips & Pro Techniques

Common mistake: a soggy center. Avoid this by browning sausage well and putting cheese directly on the dough before sauce. That barrier prevents steam from soaking the crust.
Oil the pan generously and preheat it briefly — a hot oiled surface starts the crust sear instantly and helps a crisp bottom.
Use low-moisture mozzarella to prevent excess water while baking. If using fresh mozzarella, pat dry with paper towels and use 25% less volume.
Make-ahead: assemble the pizza up to Step 6, cover tightly, and refrigerate for up to 12 hours. Add 5–8 minutes to the bake time from cold.
Professional trick for even bake: use a baking steel or preheated pizza stone on the lower rack to stabilize oven temperature and improve bottom crust color.
If you don’t have instant yeast, use active dry yeast (double-rise method): dissolve 14 g (1 tbsp) active yeast in the water and let proof 5–7 minutes before adding to flour.

Storage & reheating

Refrigerator: Cool completely, wrap slices individually in plastic wrap or store in an airtight container for 3–4 days.
Freezer: Freeze whole cooled pizza or individual slices in a single layer on a tray until solid, then wrap in foil and place in a freezer bag for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Preheat oven to 175°C (350°F) and reheat slices on a baking sheet for 10–12 minutes until warmed through. For a crisper crust, reheat at 205°C (400°F) for 6–8 minutes. Avoid microwaving — it will make the crust soggy.

Variations & substitutions

Gluten-Free Version: Replace 500 g all-purpose flour with 500 g certified 1:1 gluten-free flour blend and add 1/2 tsp xanthan gum if the blend lacks it. Dough will be slightly stickier; prebake crust 6–8 minutes before assembling. Baking time increases by 3–6 minutes.
Vegetarian Sausage Swap: Use 450 g (1 lb) seasoned plant-based sausage crumble, brown it like regular sausage, and keep quantities identical.
Spicy Sausage & Peppers: Use hot Italian sausage and add 1/4 tsp crushed red pepper to sauce; keep all other measurements the same.
Cheesy Deep Dish: Increase mozzarella to 425 g (15 oz) and add 50 g (1/3 cup) grated fontina mixed with the mozzarella for extra melt. Cheese-heavy pies may need an additional 3–5 minutes in the oven.
Smaller pan: If using a 9-inch deep-dish pan, reduce dough by about 15% (use roughly 425 g flour) and monitor bake closely to avoid burning the rim.

Serving suggestions & pairings

A simple green salad with lemon vinaigrette cuts the richness beautifully; pair with peppery arugula and shaved Parmesan.
Roasted or garlic mashed potatoes make a hearty side for deep-dish nights and echo the pizza’s comfort flavors.
Try a bright, citrusy lager or a medium-bodied Chianti to balance the tomato and sausage.
For a playful pairing, serve alongside a bold, meaty pizza riff like this Big Mac pizza mashup to compare crust approaches.

Frequently Asked Questions

Q: Why did my deep dish pizza turn out soggy in the middle?
A: Sogginess usually comes from wet toppings or underbaked center. Brown the sausage thoroughly, pat any wet vegetables dry, place cheese directly on the dough before sauce, and bake until the center reaches 74°C (165°F).

Q: Can I make this without eggs?
A: Yes. There are no eggs in this dough — it’s an oil-based dough. You can follow the recipe as written for an egg-free crust.

Q: Can I double this recipe?
A: Yes. You can double all ingredients to make two 10-inch pizzas. Mix dough in two batches or use a larger mixer bowl. Bake the pizzas separately or simultaneously if your oven fits two pans on different racks and you rotate them halfway.

Q: Can I prepare this the night before?
A: Yes. Assemble the pizza up to the point before baking, cover tightly, and refrigerate. Remove from fridge 20–30 minutes before baking and add 5–8 minutes to the baked time to compensate for cold filling.

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

Q: Can I use fresh mozzarella?
A: You can, but fresh mozzarella contains more moisture. Pat it very dry and use about 25% less by weight to prevent a watery bake.

Q: My crust browns too quickly on the edges but not the center. What should I do?
A: Move the pan to a lower rack to increase bottom heat and lower the oven by 10–15°C (25–30°F). If edges are burning, tent loosely with foil after the first 20 minutes of baking.
