Pizza Soup

Pizza Soup takes the familiar flavors of a loaded pizza—tomato sauce, pepperoni, bacon, mushrooms, green bell pepper, onion, oregano, and melted mozzarella—and transforms them into a warm, savory soup. Instead of a traditional pizza crust, thick slices of Italian bread are toasted under the broiler with melted mozzarella and served alongside for dipping.

The soup itself is intentionally simple and tomato-forward. Beef broth adds depth, petite diced tomatoes provide texture, and tomato sauce gives the base a smooth, rich body. The sautéed mushrooms, peppers, onion, bacon, and pepperoni contribute the familiar combination of toppings you might expect on a classic supreme-style pizza.

What makes the dish especially satisfying is the contrast between the hot tomato broth and the crisp cheese toast. Every spoonful offers savory meat, vegetables, herbs, and tomato, while the mozzarella slowly melts into the soup for an even richer pizza-like experience.

Key Ingredients

Pepperoni:
Pepperoni gives the soup a recognizable pizza flavor. As it heats, some of its seasoned fat and spices are released into the vegetables and broth.

Bacon:
Pre-cooked bacon contributes smoky, salty character without requiring a long frying step.

Petite Diced Tomatoes:
These provide pieces of tomato throughout the soup while releasing their juice into the broth.

Tomato Sauce:
Tomato sauce creates the smooth foundation that connects the broth, vegetables, and pizza toppings.

Beef Broth:
Beef broth reinforces the savory flavor of the pepperoni and bacon. Low-sodium or unsalted broth is particularly useful because the cured meats and cheese already contain considerable salt.

Mushrooms:
Mushrooms add earthy umami and absorb some of the pepperoni and bacon flavor as they cook.

Green Bell Pepper:
Bell pepper contributes sweetness, color, and a slightly crisp vegetable texture associated with loaded pizza.

Mozzarella Cheese:
Mozzarella is mild, creamy, and highly meltable, making it ideal both for topping the soup and for the broiled cheese toast.

Italian Bread:
Thick slices of Italian bread act as the crust component of the meal and provide a crisp contrast to the broth.

Expert Tips

Use low-sodium beef broth because pepperoni, bacon, and mozzarella are naturally salty.

Buy pre-sliced mushrooms to reduce preparation time.

Sauté mushrooms before adding them to the soup so they develop more flavor.

Give the mushrooms a few minutes alone before adding other vegetables.

Cut the bell pepper and onion into similar-sized pieces for even cooking.

Cook the vegetables only until tender rather than completely soft.

Add pepperoni after the vegetables have started softening.

Let the pepperoni heat long enough to release some flavorful oils.

Simmer the soup gently rather than boiling it aggressively.

Taste before adding extra salt.

Use freshly shredded mozzarella if possible for smoother melting.

Toast the bread lightly before adding cheese so it does not become soggy immediately.

Watch the cheese toast continuously under the broiler.

Broilers can take bread from golden to burnt in seconds.

Serve the soup immediately after adding mozzarella.

Keep the cheese toast separate until serving so it stays crisp.

Add a pinch of red pepper flakes if you enjoy spicy pizza.

Fresh basil can be added at the end for additional Italian-style flavor.

Pizza Soup

Ingredients

For the Soup

3 cups low-sodium or unsalted beef broth

1 (28-ounce) can petite diced tomatoes, with juices

2 cups tomato sauce, homemade or store-bought

1 teaspoon dried oregano

¼ teaspoon coarsely ground black pepper

2 tablespoons olive oil

8 ounces sliced mushrooms

1 medium green bell pepper, roughly chopped

1 small onion, chopped

4 slices fully cooked bacon, chopped

4 ounces sliced pepperoni, cut into smaller pieces if desired

For the Cheese Toast and Serving

About ½ loaf Italian bread, cut into 4 thick slices

2 cups shredded mozzarella cheese, divided between the toast and soup topping

Instructions

Start the Soup Base

Place a large pot or Dutch oven over high heat.

Add the beef broth, diced tomatoes, tomato sauce, dried oregano, and black pepper.

Stir well, cover, and bring the mixture to a gentle simmer.

Once simmering, reduce the heat to low and let the soup base stay warm while you prepare the remaining ingredients.

Cook the Vegetables and Meats

Heat the olive oil in a large skillet over medium heat.

Add the sliced mushrooms and cook for a few minutes, stirring occasionally.

Roughly chop the green bell pepper and add it to the skillet.

Add the chopped onion and continue cooking until the vegetables begin to soften.

Chop the pre-cooked bacon and pepperoni into bite-sized pieces, then add them to the skillet.

Continue cooking for several minutes, stirring occasionally, until the onion and bell pepper are tender and the pepperoni has released some of its flavor.

Prepare the Cheese Toast

Turn on the broiler and position the oven rack about 6–8 inches from the heat source.

Cut the Italian bread into 4 thick slices.

Arrange the bread on a broiler-safe pan and toast under the broiler until lightly golden.

Remove the pan, flip the slices, and sprinkle about ¼ cup mozzarella cheese over each piece.

Return the bread to the broiler for about 1–3 minutes, or just until the cheese is melted, bubbly, and lightly browned in spots.

Watch carefully, as broilers can brown bread very quickly.

Finish the Soup

Add the cooked mushroom, pepper, onion, bacon, and pepperoni mixture to the simmering tomato broth.

Stir well and let everything heat together for a few minutes so the flavors combine.

Taste and adjust the seasoning if needed.

Serve

Ladle the hot pizza soup into individual bowls.

Sprinkle each serving with some of the remaining shredded mozzarella cheese.

Serve immediately with the warm cheese toast on the side for dipping into the rich tomato broth.

Important Notes When Making Pizza Soup

Pepperoni and bacon both contribute significant sodium.

Mozzarella and tomato sauce can add even more sodium.

Low-sodium broth helps keep the final seasoning balanced.

Additional salt may not be necessary at all.

Pepperoni releases fat as it cooks; spoon off some if the surface becomes overly oily.

Mushrooms release water before they begin browning.

Avoid overcrowding the skillet if you want better mushroom texture.

The soup should remain tomato-brothy rather than becoming excessively thick.

If it becomes too thick, add a little extra beef broth.

If you prefer a thicker soup, simmer uncovered for several additional minutes.

Broiler settings vary dramatically between ovens.

Always use a broiler-safe pan for the toast.

Keep the bread approximately 6–8 inches from the heating element.

Cheese toast is best eaten immediately after broiling.

Refrigerate leftover soup separately from leftover toast.

Reheat the soup gently and prepare fresh cheese toast when possible.

How to Enjoy Pizza Soup After Cooking

Serve the Pizza Soup very hot so the mozzarella sprinkled over each bowl begins melting immediately.

Ladle generous portions into deep bowls, making sure every serving receives tomatoes, mushrooms, peppers, onion, bacon, and pepperoni.

Sprinkle shredded mozzarella directly over the surface. Let it sit for about a minute so the cheese becomes soft and stretchy.

Serve one piece of hot mozzarella toast alongside each bowl.

Dip the cheese toast into the tomato broth so it absorbs some of the soup while maintaining a crisp edge.

For additional pizza flavor, sprinkle dried oregano, crushed red pepper flakes, or freshly chopped basil over the top.

A little freshly grated Parmesan can also be added for a sharper cheese flavor.

For a lighter contrast, serve the soup with a simple green salad dressed with balsamic or red wine vinaigrette.

If reheating leftovers, warm the soup on the stovetop over medium-low heat and prepare fresh toast separately rather than storing it in the soup.

Frequently Asked Questions:

1. What does Pizza Soup taste like?
It tastes like a loaded pepperoni pizza transformed into a tomato-based soup, with smoky bacon, mushrooms, bell pepper, onion, oregano, and melted mozzarella.

2. Is Pizza Soup very thick?
No. This version is relatively brothy because it combines beef broth with tomatoes and tomato sauce. It can easily be reduced longer for a thicker consistency.

3. What other pizza toppings can I add?
Italian sausage, olives, banana peppers, roasted red peppers, cooked ground beef, spinach, or additional mushrooms can all work well.

4. What should I serve with Pizza Soup?
The mozzarella cheese toast is the natural accompaniment, but garlic bread, breadsticks, focaccia, or a green salad also pair well.

5. Can I make a spicy version?
Yes. Add crushed red pepper flakes, spicy pepperoni, hot Italian sausage, jalapeños, or a little Calabrian chile paste.

1. Why are the vegetables sautéed separately before being added to the soup?
Sautéing develops more concentrated flavor and better texture than simply boiling raw mushrooms, peppers, and onions in the tomato broth.

2. Why should I use low-sodium beef broth?
Pepperoni, bacon, mozzarella, tomato sauce, and bread can already contribute substantial sodium. Low-sodium broth gives you much better control over the final seasoning.

3. Why toast the Italian bread before adding mozzarella?
Pre-toasting creates a firmer surface so the bread remains crisp underneath the melted cheese rather than becoming soft immediately.

4. Can I make the soup ahead of time?
Yes. Prepare the soup and refrigerate it separately. Reheat gently and make the mozzarella toast fresh just before serving for the best texture.

5. How can I keep the soup from becoming greasy?
Choose moderately lean pepperoni and bacon, and spoon off excess rendered fat from the skillet before adding the mixture to the tomato broth.
