White Pizza CasseroleWhite Pizza Casserole is such a delicious dinner that is easy to make and can feed 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? Adding pizza to pasta? I have seen that done and I am NOT a fan. But making a White Pizza Casserole from pasta? That is one delicious decision that you will not regret. This easy meal is always a heat, its cheesy, with a crispy pepperoni top, and all the flavors of a tasty pizza in casserole form.

Mix-Ins Ideas for this White Pizza Casserole Recipe:

  • Pitted and diced black olives taste delicious in this White Pizza Casserole dish.
  • Grape Tomatoes – you can cut the in half or leave them whole. I do not recommend using sliced tomatoes as they add extra moisture.
  • Diced Bell Peppers – you can add them raw to the casserole or sauté them for 3-4 minutes before adding.
  • Drained Canned Pineapple Chunks – for a Hawaiian twist.
  • Sliced Jalapeños – remove the seeds, or leave them in for extra heat.
  • Sliced Sausage – I like to brown it for a few minutes before mixing it in.
  • Cubed Chicken – use grilled chicken, leftover rotisserie chicken, or sear some chicken on the stove until golden brown, before mixing into the casserole mixture.
  • Spinach – do not use frozen, it will add extra water to the recipe.
  • Drained Canned Artichokes – make sure you drain them well, and chop them.
  • Bacon – I like to use store-bought pre-cooked bacon to save time.
  • Caramelized Onions – you can use fresh red onions or caramelize some shallots.
  • Mushrooms – slice them first, you can add them raw or you can sauté them for 4-5 minutes.

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 it 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!
