Why You'll Love this Pizza Soup:
Weeknight-friendly: Comes together quickly with simple prep and one pot.

Classic pizza flavors: Made with Italian sausage, pizza sauce, pepperoni, olives, and melted mozzarella.
Customizable: Easy to adjust with different toppings or vegetables based on what you have on hand.
Family-friendly: A fun way to enjoy pizza flavors in a comforting, spoonable dinner.
Key Ingredients:
- ground italian sausage. Adds bold, savory flavor to the soup. Use mild or spicy sausage depending on your preference.
- white mushrooms. Classic in a supreme pizza, they add umami richness. Feel free to use baby bella, white button, or even portobello mushrooms for a deeper, earthier taste.
- marinara sauce. A shortcut ingredient that gives the soup a true pizza-like flavor. Choose a high-quality brand or even homemade marinara sauce for a fresher taste.
- vegetable broth. The base of the soup, keeping it lighter than using beef broth. You can also use homemade chicken broth for extra richness.
- mozzarella cheese. Melts into the soup for that signature pizza flavor.

Easy Substitutions & Variations:
- Swap the sausage: Use mild or hot Italian sausage, ground turkey, or ground beef if preferred.
- Change the vegetables: Add or swap in zucchini, spinach, or sliced olives based on your favorite pizza toppings.
- Make it lighter: Reduce the pepperoni or skip it entirely and rely on the sausage for flavor.
- Use different cheese: Mozzarella works best, but provolone or a mozzarella-provolone blend also melts well.
- Control the thickness: Add extra broth for a thinner soup or let it simmer uncovered for a few minutes to thicken.
How to Make Pizza Soup:
- In a large pot over medium heat, cook the Italian sausage and diced onion until the sausage is browned and the onion is soft, about 5 minutes.
- Add the mushrooms, green bell pepper, and garlic. Cook for another 3-4 minutes until the vegetables soften.
- Stir in the oregano, salt, and black pepper. Pour in the marinara sauce, diced tomatoes, and vegetable broth. Bring to a simmer and let cook for 15-20 minutes to blend flavors.
- Stir in the black olives and pepperoni. Let simmer for another 5 minutes.
- Ladle into bowls and top each serving with shredded mozzarella cheese.
Recipe Notes & Tips:
- Build Flavor in Layers: Browning the Italian sausage and onions first creates a deep, savory base for the soup.
- Don't Skip the Simmer: Letting the soup simmer for 15-20 minutes allows the flavors to fully meld together.
- Customize Your Toppings: Add crispy bacon for a meat lovers' version, jalapeños for spice, or fresh basil for an Italian twist.
- Cheese Tip: Add shredded mozzarella just before serving to keep it melty and fresh.
- Thicker Soup Option: If you prefer a thicker consistency, stir in a small amount of tomato paste or extra cheese.
- Perfect Pairings: Serve with garlic bread, a crisp salad, or parmesan crisps for extra crunch.
