Pizza soup with chicken sausage has become one of my favorite ways to get those classic pizza flavors without needing to make an entire pizza night happen (though keto pizza in the air fryer is another easy way to do this). Browning the sausage first adds so much flavor to the broth, and once the cheese melts into the soup, it tastes rich and hearty without feeling overly heavy (kind of like sausage potato kale soup without cream).
Another reason this easy pizza soup works so well is how customizable it is, depending on what you already have in the fridge. Mushrooms, peppers, olives, pepperoni, or extra mozzarella all work really well here, so it’s easy to make it feel like your favorite pizza in soup form.

Why The Recipe Works💭
Protein: Chicken sausage adds hearty pizza flavor while keeping the soup lighter and protein-packed.
Flavor: Melted cheese and rich tomato broth give the soup that classic pizza taste without needing crust.
So easy to adapt: The recipe is easy to customize with your favorite pizza toppings, making it great for family dinners and leftovers.
Items and Substitutions
- Italian chicken sausage: Make sure your sausage is gluten-free if needed. You could opt for a chorizo sausage here, too, if you’re not serving it to kiddos.
- Chicken broth: I use homemade broth as much as possible, and when I don’t have any made, I rely on bone broth powder for high-quality.
- Shredded mozzarella cheese: This cheese specifically melts beautifully on top, mimicking the cheesy goodness of pizza.

Tools you’ll need
Before starting the recipe, you’ll want to have all your kitchen essentials ready. I recommend having the following items:
Flavors To Try
Below are a few ways to adjust the low-carb, cheesy pizza soup in flavor and toppings.
- Change the Protein: Swap chicken sausage for ground beef, turkey, or even plant-based sausage for a different flavor.
- Add More Veggies: Include zucchini, spinach, or cauliflower rice for extra nutrients and variety.
- Try Different Cheeses: Use cheddar, provolone, or Gouda for a unique twist on the cheesy topping.
- Make It Creamy: Stir in a splash of heavy cream or cream cheese for a richer, creamier soup.
- Top It Your Way: Garnish with sliced olives, fresh basil, or crispy pepperoni for a personalized finish.
How To Make Keto Pizza Soup
Step 1: In a pre-heated skillet, saute the chicken sausage until browned and cooked through. Remove it and set it aside.
Step 2: Melt the butter in a pot over medium heat. Stir in the onions and peppers, and saute until softened before stirring in the garlic and Italian seasonings and the mushrooms.
Step 3: Pour in the diced tomatoes, tomato sauce, and chicken broth, and simmer for 10 minutes uncovered.
Step 4: Mix in the sausage and then the parmesan cheese, stirring until it’s all combined, and simmer for about 5 minutes. Then, serve!
Note
Sauté the veggies until they’re softened and aromatic before adding the liquids. This step enhances their flavor and gives the soup a richer, more well-rounded taste.
Helpful Hints
Pro tip: Brown the sausage well
Ensure the chicken sausage is browned thoroughly before adding it to the soup for extra flavor.
Here are some helpful hints for making crustless pizza soup.
- Adjust the seasoning: Taste the soup as it simmers and adjust the salt, pepper, or Italian seasoning to match your preferences.
- Use fresh herbs: Fresh basil or oregano can be added at the end of cooking for a burst of fresh flavor.
- Don’t overcook the vegetables: Sauté the onions, peppers, and mushrooms just until softened to retain their texture and flavor.
- Add the cheese last: Stir in the Parmesan cheese just before serving to keep it smooth, and melt the mozzarella on top for the perfect pizza-like finish.
- Storing: Let the keto soup cool completely before transferring it to an airtight container. It can be kept in the refrigerator for up to 4 days
- Freezing: For longer storage, place it in a freezer-safe container and freeze it for up to 3 months. Thaw it in the fridge overnight before you need it.
- Reheating: Warm it on the stovetop over medium heat, stirring occasionally, until heated through. Alternatively, you can microwave individual portions in a microwave-safe bowl, heating in 30-second intervals and stirring in between to ensure even heating. Add a fresh sprinkle of mozzarella cheese on top before serving for that melty, pizza-like finish!
Ways To Enjoy It
This easy keto pizza soup is filling enough to serve on its own, but it also pairs well with simple sides and extra toppings for a full pizza-night-style meal.
- Serve it with a crisp strawberry spinach salad with lemon dressing or roasted vegetables for an easy low-carb dinner that still feels hearty.
- Top each bowl with extra mozzarella, parmesan, crispy pepperoni, or fresh basil to make the soup taste even more like pizza.
- Set out toppings like olives, mushrooms, garlic butter, or red pepper flakes so everyone can customize their own bowl at the table.
