Low-Carb Chicago-Style Deep-Dish Pizza Recipe

This low-carb Chicago-style deep-dish pizza is made with a sturdy fathead-dough crust, Italian sausage, plenty of mozzarella, Parmesan, and a seasoned tomato sauce layered on top. The pizza takes about 50 to 60 minutes from start to finish, including a quick 8 to 10 minute par-bake that helps the crust hold the rich filling without becoming soggy.

Each slice delivers the hearty comfort of classic deep dish while keeping the crust keto-friendly. The almond-flour and mozzarella base turns golden around the edges, while the sausage, creamy cheese, and bright tomato topping create a deeply satisfying dinner for about six servings. For another fun low-carb option, pair the meal with our cheesy low-carb pizza dip as an appetizer.

Why You’ll Love This Recipe

Chicago deep dish is known for its tall crust, generous filling, and distinctive layering. This low-carb version keeps those signature features while replacing a traditional wheat crust with a warm, pliable fathead dough made from mozzarella, cream cheese, almond flour, egg, and seasonings.

The result is rich without feeling overly complicated. The crust bakes into a tender-chewy base with crisp, browned edges, and the filling stays wonderfully savory thanks to mild or hot Italian sausage cooked with onion and garlic.

Unlike a thin pizza where sauce and toppings sit directly on the crust, this preparation places cheese first, sausage second, and tomato sauce last. That order helps shield the bottom crust from moisture and gives every bite a balanced combination of creamy, meaty, and tangy flavors.

Ingredients You’ll Need

The crust depends on low-moisture mozzarella and finely ground almond flour. Low-moisture cheese melts smoothly without adding as much water, while the almond flour gives the dough enough structure to press into a deep pan.

• For the crust: 2 cups shredded low-moisture mozzarella, 2 tablespoons cream cheese, 1 1/4 cups finely ground almond flour, 1 large egg, 1 teaspoon baking powder, 1/2 teaspoon Italian seasoning, and 1/4 teaspoon fine salt.
• For the filling: 1 pound bulk Italian sausage, 1/2 small diced onion, and 2 minced garlic cloves.
• For the cheese layer: 1 1/2 cups shredded mozzarella and 1/4 cup finely grated Parmesan.
• For the sauce: 1 cup crushed tomatoes or passata, 1 tablespoon tomato paste, 1 teaspoon Italian seasoning, 1/2 teaspoon dried oregano, and optional red-pepper flakes.

Use mild sausage for a family-friendly pizza or hot sausage for a stronger peppery bite. The optional olive oil is only needed if the sausage does not release enough fat to cook the onion comfortably.

How to Make It Step-by-Step

Step 1: Heat the oven to 400°F (200°C), then grease a 9-inch springform pan or 10-inch cast-iron skillet very well. Pay special attention to the sides, because the tall crust needs to release cleanly after baking.

Step 2: Set a skillet over medium heat and add the bulk Italian sausage. Break it into small pieces as it cooks, then add the finely diced onion and continue cooking until the onion softens and the sausage is no longer pink.

Step 3: Stir the minced garlic into the sausage mixture and cook for about 30 seconds. Transfer the mixture from the heat and drain excess fat thoroughly, since too much grease can soften the crust in a deep pan.

Step 4: Add the crust mozzarella and cream cheese to a microwave-safe bowl. Heat the cheeses in 30-second intervals, stirring after each interval, until they are fully melted and smooth.

Step 5: Add the almond flour, baking powder, Italian seasoning, fine salt, and egg to the melted cheese. Stir firmly or knead carefully until the ingredients come together into a cohesive dough with no obvious dry pockets.

Step 6: Press the dough across the bottom of the prepared pan and 1 1/2 to 2 inches up the sides. If the dough starts to stiffen, warm it briefly, or press it between sheets of parchment before fitting it into the pan.

Step 7: Bake the empty crust for 8 to 10 minutes. It should look just set and may begin to puff, but it does not need to be deeply browned because it will bake again after the filling is added.

Step 8: While the crust bakes, combine the crushed tomatoes or passata with the tomato paste, oregano, Italian seasoning, red-pepper flakes if desired, salt, and black pepper. Taste the sauce and adjust the seasoning before assembling the pizza.

Step 9: Sprinkle most of the shredded mozzarella over the partially baked crust. Add the drained sausage and onion mixture next, then spread the seasoned tomato sauce over the top and finish with Parmesan.

Step 10: Return the pan to the oven and bake for 20 to 25 minutes. The crust should be browned and the cheese should be bubbling, with the sauce looking thick rather than watery.

Step 11: Place the pizza on a safe surface and let it rest for at least 10 minutes. Slice with a sharp knife after resting so the molten cheese and tomato layers have time to settle.

Chef’s Tips for a Sturdy Crust

Par-baking is the most important technique in this recipe. Without that initial bake, the cheese and sauce can weigh down the dough before the bottom has had a chance to set.

Drain the cooked sausage even if it appears fairly lean. In a deep pizza, grease collects at the bottom, and the almond-flour crust can absorb it and lose its pleasant structure.

For the easiest shaping, work with the dough while it is warm but not scorching hot. Parchment is especially helpful for pressing the dough into an even layer without sticking to your fingers.

• Keep the crust wall about 1 1/2 to 2 inches high for a deep, well-supported filling.
• Use finely ground almond flour for a smoother bite and better cohesion.
• Let the baked pizza rest for at least 10 minutes before cutting.
• Use a springform pan if you want especially easy removal and clean, tall slices.

Variations and Serving Ideas

The sausage-and-cheese combination is the most classic choice, but the recipe is flexible. You can add low-carb vegetables such as finely chopped peppers, mushrooms, or olives, keeping in mind that vegetables should be cooked first if they release a lot of moisture.

For a firmer crust, some cooks use 1 1/2 cups almond flour instead of 1 1/4 cups. Pork-rind crumbs can also replace part of the almond flour, and about 1/4 teaspoon xanthan gum may be added for flexibility, although neither change is necessary.

Serve each slice with a crisp green salad, roasted vegetables, or steamed broccoli. If you are planning a full comfort-food menu, our hearty pizza casserole is another satisfying dinner option to keep in your recipe collection.

Storage and Reheating

Cool leftover slices completely, then cover them tightly and refrigerate. They are best enjoyed within a few days for the freshest crust and filling.

Reheat slices in a skillet over low to medium heat, in a 350°F oven, or in an air fryer until hot. Gentle reheating helps the crust firm again while keeping the cheese pleasantly melted.

Avoid slicing the entire pizza before it has rested, since the sauce and cheese can slide apart while still piping hot. The 10-minute pause makes a noticeable difference in presentation and texture.

Ingredients

  

Crust

• 2 cups Shredded low-moisture mozzarella
• 2 tablespoons Cream cheese
• 1 1/4 cups Finely ground almond flour
• 1 Large egg
• 1 teaspoon Baking powder
• 1/2 teaspoon Italian seasoning
• 1/4 teaspoon Fine salt

Filling and Topping

• 1 pound Bulk Italian sausage
• 1/2 Small onion, finely diced
• 2 Garlic cloves, minced
• 1 1/2 cups Shredded mozzarella
• 1/4 cup Finely grated Parmesan
• 1 cup Crushed tomatoes or tomato passata
• 1 tablespoon Tomato paste
• 1 teaspoon Italian seasoning
• 1/2 teaspoon Dried oregano
• 1/4 teaspoon Red-pepper flakes
• To taste Salt and black pepper
• 1 tablespoon Olive oil, if needed for sautéing

Method

 

Step-by-Step

1. Heat the oven to 400°F (200°C). Grease a 9-inch springform pan or 10-inch cast-iron skillet thoroughly, including the sides.
2. Cook the Italian sausage in a skillet over medium heat, breaking it into small pieces. Add the diced onion and cook until softened, then stir in the garlic for about 30 seconds; drain excess fat if necessary.
3. Place the crust mozzarella and cream cheese in a microwave-safe bowl. Heat in 30-second intervals, stirring between each interval, until melted and smooth.
4. Mix the almond flour, baking powder, Italian seasoning, salt, and egg into the warm cheese mixture. Stir or knead until a cohesive dough forms.
5. Press the dough over the bottom of the prepared pan and 1 1/2 to 2 inches up the sides. Warm it briefly or press it between parchment sheets if it becomes difficult to handle.
6. Bake the empty crust for 8 to 10 minutes, just until it begins to puff and set.
7. Stir together the crushed tomatoes, tomato paste, oregano, Italian seasoning, red-pepper flakes if using, salt, and black pepper.
8. Layer the pizza in Chicago-style order: add most of the shredded mozzarella first, spoon the cooked sausage mixture over it, and spread the tomato sauce across the top. Finish with the grated Parmesan.
9. Bake for another 20 to 25 minutes, until the crust is browned and the cheese is bubbling around the edges.
10. Rest the pizza for at least 10 minutes before slicing. This allows the cheese and sauce layers to set so the slices are easier to lift and serve.

Notes

Drain the sausage thoroughly to protect the almond-flour crust from excess moisture. A 9-inch springform pan or 10-inch cast-iron skillet works well. Store leftovers covered in the refrigerator and reheat until hot.

Final Thoughts

This low-carb Chicago-style deep-dish pizza brings the best parts of the famous pan pizza to the dinner table: a tall crust, a generous cheese layer, savory sausage, and tomato sauce spooned over the top. The method is straightforward, but the par-bake, careful draining, and resting time are essential for slices that hold together.

Make it in a springform pan when you want dramatic deep-dish presentation, or use a cast-iron skillet for rustic, well-browned edges. Once you taste the combination of nutty crust, bubbling mozzarella, seasoned meat, and bright tomato sauce, this recipe is likely to become a regular weekend dinner.

Finish the meal with a small dessert if desired, such as this Southern-style bourbon cake. Prepare the pizza, let it rest, and serve generous wedges while the cheese is still warm and stretchy.
