How To Make It
Heat the olive oil in a skillet over medium-high heat.

Saute the chicken sausage until browned and cooked through. Remove and set aside.

Melt the butter in a pot over medium heat. Stir in the onions and peppers, and saute until softened.

Mix in the garlic and Italian seasoning, and saute for 30 seconds longer.

Toss in the mushrooms, and saute for 2-3 minutes.

Pour in the diced tomatoes, tomato sauce, and chicken broth, and simmer for 10 minutes uncovered.

Place the sausage in the pot, and simmer for another 5 minutes. Stir in the parmesan until well combined.

Serve the soup topped with the mozzarella cheese if desired.
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.

Storage
To store low carb pizza soup, let it cool completely before transferring it to an airtight container. It can be kept in the refrigerator for up to 4 days. For longer storage, place it in a freezer-safe container and freeze it for up to 3 months.
When reheating, thaw the soup in the refrigerator overnight if frozen. Then, 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!
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 Low Carb 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.
- Control the broth consistency: If the soup is too thick, add a little extra chicken broth to achieve your desired consistency.
- Customize the toppings: Feel free to add your favorite pizza toppings like olives, pepperoni, or fresh basil just before serving for a personalized touch.

Serving Suggestions
For a complete meal, serve the low carb pizza soup with a side of crispy, keto-friendly breadsticks or a fresh, green salad. The breadsticks provide a satisfying crunch and complement the hearty soup, while the salad adds a light, refreshing contrast. A simple mix of leafy greens with a tangy vinaigrette or creamy dressing pairs perfectly with the rich, cheesy flavors of the soup.
If you’re craving something rich, top your soup with extra mozzarella cheese and a sprinkle of Parmesan before serving. You can even add some crispy pepperoni slices or crumbled bacon for an added layer of texture and flavor. These small additions make the soup feel even more like a pizza experience, enhancing its deliciously comforting nature.
For a fun twist, serve the soup in individual bowls and offer a variety of optional toppings on the side. Guests can personalize their servings with fresh basil, sliced olives, or a drizzle of garlic butter. This approach makes the meal interactive and customizable, allowing everyone to enjoy the soup the way they like.
