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.

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!

I'd do extra time on the treadmill so I could have a bowl of this!



I love that the family can customize this however they like! Everyone's happy!



This looks fantastic! I know this will quickly become a family favorite!



This would be fun to add in half of what the kids like and half of what the parents like! Loving the cheesy goodness!

I am thinking of all the ways I can change this up as I am reading your mix in ideas! They all sound amazing!



Oh wow, that is so cheesy and perfect! My kids will love it!

This casserole looks so delicious!

That's the perfect comfort food right there!



The White Pizza Casserole is so freaking delicious!! My sister made this recipe for dinner last night, and I was enjoying every single bite. The pasta is rich, and a little goes a very long way. It's comfort food at its finest. Thank you, Catalina for this amazing recipe. :-)


Beth LaMotte

Absolutely delish.  I bumped up the veggies by adding sautéed mushrooms, fresh baby spinach, and sundried tomatoes.  I did not have fresh herbs so I used Italian seasoning.



4 cups uncooked pasta or 4 cups cooked pasta?


uncooked and cook to package directions



How is this a WW dish? It is over 32 points...


who said this is a WW dish?



Made the Cheesy White Pizza Casserole last night following the directions as written.  It was very good; we both had seconds and I will make it again.  I used a 9X13 pan but will use a smaller pan next time so the casserole will be thicker (in height).  The recipe does not give an oven temperature so I cooked it at 350 degrees.  


Hi Nettie, thank you for your comment, we are glad you have enjoyed it. The temperature is at 350 degrees F and is listed in the recipe card, you probably missed it. Thanks!



Sooooo good! I made the recipe as written except for leaving out the pepperoni for part of it and cooking in two pans. Everyone gobbled it down and my husband even said it tasted like restaurant food! Thanks for the amazing recipe!



Made this again following the recipe as written - so good.  I probably need to double the recipe next time to have more left over.  I like this recipe better than pizza casserole using a red sauce as that is too close in taste to spaghetti casserole.

I’d like to prepare a few pans to freeze them for later. Do I need to cook them thoroughly first or freeze once I have everything in the pans? Thanks.


Don't cook, the pasta will be overcooked it you do so. Just mix and freeze.
