Delicious Slow Cooker Pizza Casserole

This slow cooker pizza casserole is a great dinner dish for feeding a hungry mob of people. It’s a great meal for feeding a family as both kids and adults will love this tasty pizza dish.

Slow Cooker Pizza Casserole

The pizza sauce mix we make for this casserole cooks out to be rich and packed full of flavor. Once it’s layered with the pasta, cheese and slow cooked for several hours, you’re going be amazed at just how good this tastes.

Personally, I don’t ever really need sides to go with this casserole as it’s more than enough on its own. However, if you are looking for some sides, then I highly recommend some freshly baked crunchy garlic bread.

I love to keep the leftovers of this dish as they’re great for lunch the next day. Just make sure you keep them stored in the fridge or freezer until needed. It will last a few days if you’re storing it in the refrigerator.

Pizza Casserole

Typically cooking pasta in the slow cooker for a long time tends to make it go to mush and not be very pleasant but surprisingly this came out so good. I recommend trying to use a higher quality pasta, so you get the best results possible.

Slow cooking can take a long time so it can be off-putting for some. If you need an easy pizza casserole fast, then you can always do this in the oven instead. It just comes down to what you’re feeling like and how much time you have.

Recipe Tips

  • You’re able to skip the browning of the ground beef, but it will add quite a bit more greasy fluid to the dish. I always recommend browning the ground beef before adding it to the slow cooker, but it isn’t compulsory.
  • If you love your vegetables, then don’t hesitate to add a few more to this dish. Carrot and mushrooms are two great vegetables that work great in a pizza casserole.
  • You’re able to swap the ground beef for some sliced Italian sausages or something similar.You will also find that ground pork, or chicken will also work great.

    I’ve been making this for years. I love how versatile it is changing ingredients to whatever pizza toppings you like or what you have on hand. It also travels well for potlucks.

    I gave this recipe 5 / 5

      Made this with bottled Alfredo Sauce. Came out good except 6 hours was too long in my crockpot- some of pasta was dry & overcooked. Still like this & will make again at low for 3-4 hours.
