White Pizza Casserole is a delicious blend of cheesy white pizza sauce, pasta and lots of pepperonis, baked to crispy perfection in a casserole dish. Check out the short video tutorial below and learn how to make the best pizza casserole!

Casserole recipes are a staple around here, they are easy to make and usually make enough leftovers that you don’t have to worry about cooking dinner the next day. My other favorites are Cheesy Crack Chicken CasseroleChicken Hash-brown Casserole. and Chicken Spaghetti Casserole.

Cheesy White Pizza Casserole

White Pizza Casserole is such a delicious dinner that is easy to make and feeds a large family. I can never say no to cheese and pasta and if it would be my way, I would probably survive on pizza and ice cream. Well, I do love greens and healthy meals, but pizza and pasta are my weaknesses.

Now, wouldn’t it be great if the two were combined, by making a White Pizza Casserole from pasta? That is one delicious decision that you will not regret. This easy meal is always a hit, its cheesy, with a crispy pepperoni top, and all the flavors of a tasty pizza in casserole form. Kids will also fall in love with this casserole.

This recipe is so easy and adaptable that you can add your favorite mix-ins just like you would choose them to top a pizza. The combinations are endless, you just have to use your imagination and use the ones you like more. I am a huge fan of adding just pepperoni.

We also like this casserole with spicy jalapeños, sausage, and chicken. You can make it vegetarian by mixing in mushrooms, tomatoes and a handful of fresh spinach. Or transform into a Margherita casserole by adding 1/3 cup pesto and cherry tomatoes, top it with fresh buffalo mozzarella for the ultimate cheesy top!

Recipe Tips

  • Use quality pepperoni, it will make a huge difference in this dish.
  • If you prefer the casserole spicy add jalapenos, or add some hot sauce into mixture.
  • This meal is loaded with cheese, don’t skip it, its what makes it so creamy and comforting.
  • Mozzarella cheese can also be substituted with provolone cheese or sharp cheddar. For a spicy twist, use Pepper Jack.
  • You can add sliced mushrooms or black pitted olives to this dish.

Can you use other meats to make this Casserole?

Absolutely! You can substitute pepperoni with chicken, turkey or bacon. The cooking time might vary as well based on each meat type.

How to freeze and thaw this Cheesy White Pizza Casserole?

To freeze, cover pan tightly with plastic wrap and foil. Freeze for up to 3 months. When ready to cook, thaw in refrigerator overnight. Remove cover and bake at 350 degrees for about 30-45 min.

Can I use a different pasta? All I have is corkscrew rotini?


yes, sure!



Anyone try this with half and half to help cut down on the calories? Can it be used?



Can you use half and half to help reduce the calories a little bit? Has anyone tried it?


Yes, you can!



Hi, I was wondering if this could be made during the day (not the oven bit) and then cooked in the oven later on or do you have to cook it straight away? Thank you :)


Yes, totally, assemble it during the day and cook it at night!



I did make this exactly how you did it and it was so yummi, there was enough left over for our dinner the next day and it still tasted lovely, keeping this one and I love that you can "jazz" it up a bit depending on what you have to hand. Thank you for sharing.



If I wanted to freeze this do I cook it first and then freeze? Or do I freeze all ingredients in pan and then cook?


Both ways work well. You can cook and freeze the leftovers or assemble everything, freeze, and cook when ready.



Omg this was divine. I came across a deal in my local Kroger on Boar’s Head sliced pepperoni and bought it not knowing what I was going to do with it. Then I remembered having saved this recipe! I had everything I needed except the fresh onion so used onion powder. My husband likes pasta practically swimming in sauce so I made 1 and 1/2 times the sauce and it was nice and saucy. Definitely going to make this again. Thank you for posting, I would have never thought of putting pepperoni in a pasta dish like this!


Thank you for your feedback!
