Easy Pizza Soup Recipe
I can’t think about eating pizza soup without thinking of my dad. He passed away 7 years ago, but this was a dish he enjoyed making for my kiddos when they were “wee little bairns,” as he used to call them.
I mean, what would be better for kids than pizza as a soup with sneaky vegetables added in?! And I’m serious….this DOES taste like pizza!
While he used to serve his pizza soup recipe in a toasted bread bowl, it’s also delicious without that for making this a keto pizza soup, or one that’s gluten-free. This recipe isn’t his exact pepperoni pizza soup, but it is my variation of his original.
I’ve changed it a little by cooking it in the instant pot and crockpot (he always made his on the stovetop), dropping the bread bowl, swapping the zucchini for mushrooms, and adding a touch of whipping cream.

Ingredient Notes
The pepperoni pizza soup ingredients *almost* resembles a combination or supreme-style pizza. We decided to skip the cooked Italian sausage since we really wanted this to be “dump and go” for the instant pot and crockpot pizza soup.
- canned diced tomatoes
- chicken broth
- mushrooms – sliced
- garlic salt
- red or green bell pepper – cut into 1” pieces
- dried Italian seasoning
- Pepperoni
- Mozzarella cheese – shredded
- sliced black olives – drained
- whipping cream
- Garnish – Fresh basil and shredded parmesan (optional)
Variations
- Meats – We are using just pepperoni for our keto pizza soup, but feel free to add cooked Italian sausage, pre-cooked bacon, ham, or shredded chicken as well.
- Whipping Cream – We love using whipping cream, but if you would prefer to lighten up your soup you can skip it. It’s delicious either way!
Equipment
A Pressure Cooker – This is the Instant Pot model that we used.
A Crock Pot
Diet Adaptations
- Keto/Low-Carb – While our pizza soup recipe is keto-friendly and low-carb, you are going to want to watch for hidden sugars in your canned tomatoes. Avoid hidden sugars in pre-shredded cheese by using block cheese and shredding your own.
- Paleo– skip the dairy and stir in plant based milk if you want to add a touch of creaminess
- Vegetarian – Make your keto pizza soup vegetarian by swapping the chicken broth for vegetable broth, skipping the meat, adding extra vegetables, and omitting the whipping cream and mozzarella (some vegetarians do eat dairy, but that is up to you).
Step by Step Instructions
No matter how you choose to cook it, your instant pot or crock pot pizza soup is super simple and ready for you dinner table. Kid-friendly, you can always have the kids right in the kitchen with you.
Prep
Prep the ingredients by slicing the mushrooms, dicing the bell pepper, and cutting the pepperoni pieces into quarters.
Instant Pot Instructions
Add all of the ingredients except the whipping cream, shredded cheese, and garnishes to the pot, which means: the diced tomatoes in juice, chicken broth, sliced mushrooms, diced pepper, garlic salt, Italian seasoning, black olives, and pepperoni.
Cook on MANUAL ( or PRESSURE COOK) for 1 minute.
Do a natural release for 3 minutes and then do a quick release.
Slowly stir in the cheese. I usually do this in a few small batches and make sure to fully mix the cheese before adding in more. If you dump all of the cheese in at one time it sometimes doesn’t fully break down, or even worse it sinks and sticks to the bottom of the pot.
Once the cheese is melted, add the whipping cream. Since the soup is already so hot, it works perfectly fine to mix the cold whipping cream in even if the pot is off.
Serve and enjoy!
Crock Pot Instructions
Add the tomatoes, chicken broth, mushrooms, bell pepper, garlic salt, and Italian seasoning to the crockpot.
Cook on high for 2 hours or low for 4 hours.
Stir in the pepperoni, olives, shredded cheese (mix in batches to keep it from clumping), and whipping cream and keeping the setting on low, heat until the soup is warm throughout.
Serve your crock pot pizza soup immediately. Enjoy!
Recipe Tips
- We sliced the pepperoni slices into quarters, but you could also use the mini pepperonis as well.
- Be sure to add the cheese to the soup slowly and allow it to incorporate fully to avoid clumping.
- This recipe doubles easily for a crockpot or you can also double it if you have an 8 qt pressure cooker.
- If you aren’t watching your carbs or eating gluten-free, the pizza soup can be served in a bread bowl or you can add garlic toast croutons or tortellini pasta.
Common Questions
If you are trying to stay low-carb or gluten-free, we recommend serving your keto pizza soup with a simple side salad. If you are not trying to follow a specific eating plan, you can serve your soup in a bread bowl like my Dad would have or topped with croutons.
Store any leftover pepperoni pizza soup in the fridge in a covered container and use within four days.
You can freeze pizza soup, but you are going to want to freeze it before you add the cheese or whipping cream. It will last in the freezer for up to 3 months. When you are ready to serve it, thaw and warm then add the cheese and whipping cream.

Notes
This recipe doubles well for a crockpot or you can also double it if you have an 8 qt pressure cooker.
You can also cook ground Italian sausage or ground beef in advance, drain the grease, set it aside, and add it to the pot when you add the pepperoni.
Other variations include swapping some of the tomatoes for pizza sauce to make it a little thicker or stirring in softened cream cheese at the end instead of using heavy whipping cream.
To make a vegetarian pizza soup, use vegetable broth instead of chicken and instead of pepperoni, increase the vegetables or swap the pepperoni for zucchini slices or plant based sausage.
If you aren't watching your carbs or eating gluten-free, the pizza soup can be served in a bread bowl or you can add garlic toast croutons or tortellini pasta.

I put the mozzarella in and it didn’t integrate well into the soup and I was left with clumps of cheese. I think that next time I will use parmesan as I think it will melt better. Other than that I thought it was delicious.
WholeLottaYum says
We highly recommend using cheese from a ball you shred yourself, the pre-shredded cheese adds potato starch which makes it harder to melt and blend in. I also recommend stirring in the cheese a little at a time until the first bit is mixed in and then add a little bit more. Sorry that the cheese clumped but I’m glad you liked the flavor!
Tammy Blizzard says
I made it how I like pizza – italian sausage and pepperoni, mushrooms and onions. I dropped the pepper and olives.
I did use fresh garlic instead of garlic salt, and then sprinkled the mozzarella on at the end b/c I was afraid it wouldn’t melt and integrate well in the soup.
I also separated a portion out and put pasta in my family’s share. An easy way for me to get the low carb I want, and the pasta they can eat!
Delicious and will make again!
Jolene says
This soup was fabulous. I did the crockpot version and I also added a pound of ground beef to make it a little more “heavy”. I was delicious!
WholeLottaYum says
Thank you, I’m glad you enjoyed it! Thanks for sharing about the ground beef idea, cooked ground Italian sausage would be tasty too!
Cathy Pelletier says
Can this Soup be frozen? Thx
Ludona Smith says
I rarely make one of your recipes as soon as I’ve read it, but today I did make the Creamy Pizza Soup! Even with a change and an omission it is terrific! Next time I’ll have cream instead of Greek yogurt and frozen chopped green pepper!
WholeLottaYum says
Thanks for the feedback on the pizza soup! I’m glad you enjoyed it! Frozen peppes and yogurt sound like a great variation 🙂
