Chicago deep-dish pizza is a culinary icon, renowned for its thick, buttery crust, generous layers of cheese, and hearty tomato sauce. Unlike traditional New York-style or Neapolitan pizza, the Windy City’s deep-dish variant is more akin to a savory pie, packed with bold flavors that distinguish it from any other pizza on the map. But what truly makes a Chicago deep-dish pizza unique is not just its structure — it’s also the careful selection and arrangement of toppings. In this article, we’ll explore the traditional and popular toppings found in a Chicago deep-dish pizza, how they are layered, and what makes them essential to the dish’s identity.
Understanding the Structure of Chicago Deep-Dish Pizza
Before we dive into the specific toppings, it’s vital to understand how a deep-dish pizza is constructed. Unlike standard pizzas, where ingredients are layered in the order of crust, sauce, cheese, and toppings, a Chicago deep-dish pizza flips this sequence.
The Reverse Layer Technique
The hallmark of Chicago deep-dish pizza is its reverse layer method. Here’s the typical assembly order:
- Crust: A thick, high-rimmed, buttery crust baked in a deep, round pan.
- Cheese: A layer of rich, gooey cheese covers the crust.
- Toppings: Meat, vegetables, and other flavorings go on top of the cheese.
- Tomato Sauce: A chunky, seasoned tomato sauce is the final layer, resting on top of the other ingredients.
This layering prevents the crust and cheese from burning during the longer baking time, and it allows for an intense melding of flavors without compromising texture.
Traditional Cheese Used in Chicago Deep-Dish Pizza
Mozzarella: The Foundation of Flavor
The cheese in a Chicago deep-dish pizza is not just a topping; it’s a structural and flavor element. Traditionally, mozzarella cheese — usually a combination of low-moisture and fresh mozzarella — is used. This cheese melts into a thick, creamy layer that blankets the bottom of the deep pan, creating a rich and gooey foundation.
Why Mozzarella Stands Out
Mozzarella is preferred for several key reasons:
- It melts evenly, covering the crust comprehensively.
- It has the perfect balance of stretchiness and flavor.
- Its moisture content is just enough to avoid interfering with the sauce, which comes later in the bake.
This cheese layer also acts as a protective barrier, preventing the crust from becoming soggy when the heavy tomato sauce is added.
Meat Toppings: What Makes a Deep-Dish Hearty
Meat toppings are a staple in classic Chicago deep-dish pizza. While not all deep-dish pies include meat, it is a popular and deeply traditional aspect of the dish, especially at pizzerias like Uno Pizzeria & Café and Lou Malnati’s.
Italian Sausage: The Signature Meat
The most common meat topping in a Chicago deep-dish pizza is Italian sausage. This is typically a fennel-infused, mildly spiced sausage that is crumbled and then baked into the pizza, allowing its oils to infuse the cheese and the sauce below.
The Role of Italian Sausage in Deep-Dish Flavor
Italian sausage contributes several key flavor components:
- It adds a savory, umami profile that balances the acidity of the tomato sauce.
- Its fennel notes lend a distinct herbal complexity to the pie.
- Because it’s placed over the cheese layer, the sausage browns slightly during baking, adding a delicious texture contrast.
Pepperoni: A Popular Optional Addition
While not as deeply rooted in tradition as Italian sausage, pepperoni is a popular meat topping, especially for those who enjoy a bit of spice and crispiness. In deep-dish, pepperoni is generally placed in a single layer and melts slightly beneath the sauce, giving it a slightly different texture than the cupped pepperoni seen on standard pizzas.
Vegetable Toppings: Enhancing Depth and Nutrition
Although deep-dish pizza is famous for its heavy, indulgent ingredients, vegetables are often added to bring in balance and fresh contrast. While not every deep-dish pizza will include vegetables, many recipes feature them to complement the richness of cheese and meat.
Green Peppers, Onions, and Mushrooms
Common vegetable additions include:
- Green peppers: Add a slight sweetness and crisp texture.
- Onions: Usually caramelized slightly for a sweet, savory note.
- Mushrooms: Typically sliced and lightly sautéed, they offer an umami-rich element.
How Vegetables are Incorporated
These toppings are placed above the cheese layer and beneath the sauce, meaning they get a longer bake time. This slow cooking allows the vegetables to intensify in flavor and soften in texture, adding a new dimension to the dish.
Spinach and Tomatoes
Some modern variations also include spinach and tomatoes, especially in vegetarian or premium deep-dish options. Spinach wilts under the heat, while sliced tomatoes add a juicy brightness that cuts through the heaviness of the cheese and sauce.
The Sauce: A Defining Characteristic
The sauce is arguably the most important component in any pizza, and in Chicago deep-dish, it plays a starring role. It’s added as the final ingredient before baking, resting atop the other toppings.
Chunky, Tomato-Based Sauce
The sauce is usually a thick, hand-blended tomato sauce that includes herbs like oregano, basil, and thyme. Garlic and Parmesan are sometimes added for a more robust flavor. The sauce is notably less acidic than many American-style pizza sauces, allowing it to balance the richness of the cheese and meats below.
Handcrafted vs. Commercial Blends
Premium pizzerias in Chicago often make their sauce from scratch using whole San Marzano tomatoes, which give a deeper, sweeter flavor. Others may use commercial blends but still maintain a thick, hearty consistency.
Sauce Consistency and Baking Time
The sauce is applied so thickly that it’s almost like a soup at the beginning of the baking process. However, as the pizza cooks (usually between 40 to 50 minutes), the sauce reduces and thickens, allowing its flavors to mature alongside the rest of the ingredients.
Bonus Toppings and Customizations
While the traditional deep-dish pizza follows a specific set of toppings and arrangements, modern pizzerias have embraced creativity and customization. This has led to a wide range of additional toppings that cater to dietary preferences and contemporary tastes.
Olives and Anchovies
Some pizzerias offer Kalamata olives or anchovies for those who enjoy a salty, briny flavor. These toppings are typically light but add a powerful punch when used in moderation.
Ham and Bacon
Though less common than Italian sausage or pepperoni, ham and bacon are sometimes added, especially in combination pizzas or for those seeking alternative meats. Bacon, in particular, adds a smoky essence that pairs well with the richness of the cheese.
Eggplant and Artichoke
For vegetarians, eggplant and artichoke have become popular additions. These ingredients are often pre-cooked to remove moisture and then layered for maximum flavor without creating a waterlogged pie.
The Role of Oil in Deep-Dish Pizza
One ingredient that should not be overlooked is the oil — typically used liberally in the deep-dish pan to enhance the crust and cook the toppings effectively.
Butter and Oil in the Crust
The Chicago deep-dish pizza crust is usually made with a high-fat content due to the inclusion of butter or vegetable oil. This creates a crisp exterior and a soft, flaky interior.
Oil in the Pan
Each deep-dish pizza is baked in a well-oiled pan, often round and deep enough to hold the entire structure. The oil browns the outer crust and gives it a distinctive golden hue and crispy texture. It also acts as a medium for the cheese and toppings to partially fry, adding depth of flavor.
Pizza Toppings by Preference and Location
While there are key traditional toppings for Chicago deep-dish pizza, preferences vary across neighborhoods and pizzerias. Some of the most iconic spots in the city offer their own twist on the toppings, contributing to the rich diversity of the dish.
Wicker Park vs. South Side Favorites
In Wicker Park, you may find higher-end or experimental toppings, such as spinach and feta or grilled chicken. In contrast, classic South Side pizzerias like Lou Malnati’s and Giordano’s stay true to the original meaty, cheesy blueprint.
Regional Variations of Deep-Dish
In addition, some suburbs and nearby cities have developed their own variations:
- North Side: More likely to include premium toppings like prosciutto or roasted garlic.
- Downers Grove: Known for hearty, oversized meat pies with extra cheese.
- Glenview: Offers deep-dish with gourmet twists, including gourmet oils and truffle-infused sauces.
This culinary diversity allows even traditionalists and food adventurers to find a version of deep-dish pizza that matches their taste profile.
How to Order a Chicago Deep-Dish Pizza
For tourists or first-time deep-dish tasters, ordering can be as confusing as the toppings themselves. Here’s a brief guide on what to expect and how to personalize your pizza.
Choosing Your Toppings
Most pizzerias offer a built-to-order experience. Here’s how to navigate topping choices:
- Decide on your crust type — classic, gluten-free, or stuffed.
- Choose your cheese — traditional mozzarella, or maybe a mixed cheese blend.
- Select your meat — Italian sausage is a classic, but pepperoni and bacon are popular, too.
- Add vegetables if you wish — sautéed spinach, onions, or peppers are all flavorful options.
- Confirm the sauce — most places use their house-made tomato sauce, but some offer alternative options, like pesto or white sauce.
Pizza Sizes and Portions
Deep-dish pizzas come in various sizes, typically 4″ personal pies or full 14″ to 16″ family-style options. Because of the rich nature of the dish, a full 16″ pie is often enough for 3-4 people.
Why Chicago Deep-Dish Stands the Test of Time
While some modern pizza trends come and go, Chicago deep-dish continues to thrive both locally and internationally. Its distinct composition — a dense, hearty crust, thick layer of mozzarella cheese, generous toppings, and a rich tomato sauce — creates a flavor profile that is unmatched. Whether you’re a meat lover or looking for a vegetarian-friendly option, the flexibility and variety of toppings ensure that there’s something for every palette.
New Generations of Deep-Dish Enthusiasts
Today, younger generations and global foodies are discovering this iconic dish through pop culture, social media, and travel. As a result, deep-dish pizza continues to gain new fans, with innovative toppings and dietary adaptations (like vegan cheese or keto crusts) being introduced.
Deep-Dish as a Cultural Symbol
Beyond the toppings, deep-dish pizza is a symbol of Chicago’s resilience, community, and appetite for bold, rich flavors. It’s a dish that demands to be shared, appreciated slowly, and enjoyed with a certain reverence — much like the city itself.
Conclusion: The Flavor-Filled Heart of Chicago
The allure of Chicago deep-dish pizza isn’t just in its height or presentation — it’s in the delicious layers that each play a vital role in delivering that unforgettable, rich bite.

So next time you’re asked, “What toppings are in a Chicago deep-dish pizza?” you can confidently say: it’s not just a pizza — it’s a masterpiece of flavor, texture, and tradition, built layer by layer.
What makes Chicago deep-dish pizza different from other pizza styles?
Chicago deep-dish pizza is distinguished by its thick, high-edged crust that forms a deep dish, allowing for a generous amount of ingredients layered inside. Unlike traditional pizzas where toppings are placed over the sauce, deep-dish pizza typically layers cheese directly on the dough, followed by meats, vegetables, and finally a chunky tomato sauce on top. This style creates a rich and hearty pie that’s more like a casserole than a thin-crust pizza, making it unique in both structure and flavor.
Additionally, the deep-dish pizza uses a buttery, flaky crust that’s more akin to a pie crust than the crispy or chewy crusts found in other pizza styles. The deep pan used for baking also contributes to the pizza’s distinct look and texture, allowing the cheese and toppings to cook evenly and develop a golden, crispy layer around the edges. This structural and stylistic difference defines the Chicago deep-dish pizza and helps it stand apart from New York, Neapolitan, or Sicilian styles.
What are the typical cheese options in a Chicago deep-dish pizza?
Traditional Chicago deep-dish pizza uses a layer of mozzarella cheese as the primary cheese. This cheese is applied directly on the dough, acting as a moisture barrier to prevent the crust from becoming soggy from the tomato sauce and juicy toppings. Mozzarella is valued for its stretchy texture and ability to melt well, helping to bind the layers of ingredients together and create a cohesive and satisfying bite.
In some variations, particularly those influenced by Wisconsin cheese-making traditions, a blend of cheeses might be used, including provolone, cheddar, or even feta, depending on the pizzeria’s preferences. Regardless of the cheese blend, the key goal remains consistent: to create a rich base that can stand up to the weight of the sauce and toppings while contributing a creamy texture and complementary flavor.
What types of meats are commonly used in Chicago deep-dish pizza?
Popular meats used in Chicago deep-dish pizza include Italian sausage, pepperoni, and sometimes bacon or meatloaf-inspired fillings. Italian sausage is the most traditional choice and is often crumbled and seasoned with fennel, providing a savory and slightly sweet flavor that pairs beautifully with the tangy tomato sauce. These meats are layered above the cheese so they cook evenly and release their oils and flavors throughout the pizza.
Pizzerias may offer additional meat toppings such as ham, salami, or even customizations like chicken or chorizo for specialty pizzas. Whether sticking to classic choices or experimenting with new flavors, the meats in a deep-dish pizza are selected for their richness and ability to complement the other ingredients without overpowering the unique layered experience.
Are vegetables commonly used in Chicago deep-dish pizza?
While Chicago deep-dish pizza is often associated with hearty meat toppings, vegetables are also popular and commonly included to enhance flavor and texture. Typical vegetable options found in the layers include mushrooms, onions, green peppers, and spinach. These ingredients are usually added after the cheese layer and before the sauce, allowing them to cook thoroughly in the oven and blend well with the other components.
Fresh toppings like tomatoes or artichokes may be used in certain specialty or gourmet versions of deep-dish pizza. Vegetarian options are widely available at many pizzerias, offering a delicious and hearty alternative to meat-based toppings while still honoring the traditional deep-dish structure. Vegetables provide a balance to the richness of the cheese and meats, making each bite more flavorful and satisfying.
What kind of sauce is used in a Chicago deep-dish pizza?
The sauce used in Chicago deep-dish pizza is typically a thick and chunky tomato-based sauce, often referred to as a “marinara” or “pizza sauce.” Unlike traditional pizzas where sauce is applied before cheese, in deep-dish, the sauce is usually the topmost layer, placed over the meats and vegetables. This placement allows it to cook evenly and infuse the layers with its robust, tangy flavor.
This sauce is known for its rich texture and minimal cooking prior to being added to the pizza. Many Chicago pizzerias use hand-crushed tomatoes seasoned with herbs like oregano, basil, garlic, and olive oil. The result is a deeply savory, slightly sweet sauce that complements the buttery crust and mozzarella cheese without overwhelming the other ingredients in the dense layers of flavor.
Can I customize the toppings on a Chicago deep-dish pizza?
Yes, many Chicago deep-dish pizzerias allow for customization of toppings, letting patrons modify or add ingredients to suit their tastes. While traditional toppings like Italian sausage, green peppers, onions, and mozzarella provide a time-tested flavor profile, various modern adaptations include toppings such as jalapeños, tomatoes, and even gourmet items like spinach-artichoke or shrimp. Custom orders can turn a classic pizza into a personal culinary experience.
However, due to the pizza’s deep and layered structure, there is a limit to how many toppings can be added without affecting the texture or cooking process. Most pizzerias will guide customers on ideal topping combinations to ensure the pizza maintains its integrity and flavor balance. Ultimately, customization options depend on the specific establishment, but the deep-dish pizza is flexible enough to accommodate a variety of preferences within its hearty format.
Is Chicago deep-dish pizza considered a healthy option?
Chicago deep-dish pizza is generally not classified as a “light” or “low-calorie” dish due to its rich layers of cheese, meats, and thick crust. Depending on the toppings chosen, a single slice can be quite dense in calories and fat. While it’s a hearty and satisfying meal, those monitoring their dietary intake may find it challenging to incorporate into a strict health plan without modifications.
However, some pizzerias have adapted to healthier trends by offering lighter cheese blends, whole-wheat crust options, and an array of vegetable toppings to provide nutritional balance. Customers also have the option of choosing leaner meats, such as grilled chicken instead of sausage, or even enjoying a smaller portion. With thoughtful ingredient choices, Chicago deep-dish pizza can still be enjoyed in moderation while respecting dietary goals.
