    Try this slow cooker pizza casserole for a family dinner. It is easy to make and full of the flavors of pizza. This crockpot recipe is ideal for busy days.

    Slow Cooker Pizza Casserole Scoop

    My family loves pizza in all forms. We make regular homemade pizza, skillet pizza, pretzel pizza, breakfast pizza, pizza balls, pizza sandwiches, and pizza dip. Today I’m sharing a pizza casserole recipe. One of our favorite lasagna recipes is similar to pizza since it includes pepperoni, pizza sauce, and alfredo sauce.

    Lasagna takes a little work to make because you have to boil the noodles and then assemble all of the layers. This Slow Cooker Pizza Casserole is so easy to make and the crock pot does the work!

    Pour pasta sauce and alfredo sauce into greased slow cooker.

    Add one pound of uncooked ziti and 1/2 cup of water.

    Mini Pepperoni in slow cooker

    Top the noodles with mini pepperoni (or a 1 1/2 cup mixture of pepperoni and sausage).

    shredded cheese in slow cooker

    Pile on a bunch of shredded cheese.

    Mix together the sauces, ziti, pepperoni, water and cheese.

    spread pizza sauce over pasta

    Top with pizza sauce.

    Cover and cook on low for 3-4 hours, until the pasta is tender. Mine was ready in three hours.

    Crock Pot Ziti

    If you love saucy pasta, add some more pizza sauce to the top.

      Do the noodles absorb some of the sauce because it looks like there’s a lot of sauce? Looks great though!!

        Hi Kaelin,
        Yes, the noodles definitely absorb a lot of sauce. If you find that your pasta didn’t, you can skip adding the additional sauce at the end.
        Happy Cooking!

        Hi Jean!
        I used my 6 quart Crockpot but there was extra room so I think you would be able to use a 3.5 to 4 quart size. Happy crocking!

      Don’t the noodles get gross sitting in the crock pot for 3 hours?

        They were delicious but if you are concerned, you might be better off making my Triple Meat Pizza Casserole recipe: http://www.thegunnysack.com/one-pot-pasta-triple-meat-pizza-casserole/ Best of luck! ~Tonia

      Have you tried making this with a gluten-free pasta?

        No, I have not. I don’t have a lot of experience working with gluten-free pasta. Best of luck! ~Tonia

      I love that you added regular ol’ pizza sauce AND alfredo for that creaminess. This casserole looks to-die for!
