Last year I asked a group of friends what makes a recipe easy. One of the things they told me was how much they love one pot recipes. I get it completely. A recipe that comes together in one pan makes for a simpler recipe and minimal clean up.

This One Pot Pizza Casserole is it! It has all the flavors you love of pizza in a cheesy skillet with pasta. It is easy to make, and absolutely delicious. Besides, it is easy to customize with things your family loves.

Thank you so much, Lisa, for another amazing, quick and easy dinner!! I made this tonight, for the second time, and it’s so delicious, and a huge hit!

How to Make a Pizza Casserole

The key to making this recipe work is having a large enough skillet and using enough liquid to cook your pasta. With those two things down you have an easy stovetop recipe!

This is just a brief overview of the recipe, please make sure to read the full ingredient list and instructions in the recipe card below.

  1. Brown the meat and sauté the vegetables. Combine the Italian sausage with the green pepper and garlic in the skillet until the vegetables are soft. There is no need to fully cook the meat here, it will continue cooking as we go.
  2. Add in seasonings and liquids. Pour in the tomatoes, stock and spices. Make sure to scrape up any browned bits from cooking the meat.
  3. Add the pasta. Now bring it all to a boil. Then reduce it to a simmer. You want to see bubbles the size of grapes here and there.
  4. Finish it off. We end this dish by stirring in some cheese, topping it with more, and adding some pepperoni and olives before popping it in the oven for a few minutes.

Making One Pot Recipes Work

As mentioned above, the balance of liquid to pasta is what makes this recipe work. It makes for an easy dish that doesn’t require cooking the pasta separately. That said, if you use more pasta or less liquid, it won’t all be able to cook in the skillet together.

Another key component of this recipe is starting it on the stove and then finishing it off in the oven. It makes it a quick meal. But by making it in an oven proof skillet, we also save on clean up time! Below you will see one of my favorite brands of oven proof skillet. The one you see pictured here is from IKEA. I also love it, but it isn’t as easy to purchase online.

Type of Pasta to Use

I am calling for rotini in this recipe, those spiral shaped noodles. You could definitely use something else here, but keep in mind that it might alter the cooking time and you may need to add more liquid. If you do use a different type of noodle, I suggest picking the noodle that is closest in shape to these that your kids like best. I would not suggest using spaghetti, as it would be difficult for this cooking method.

Shredding Cheese for Pizza Casserole

You know this story by now! This recipe call for shredded cheese. And you can see by that glorious pulled cheese photo above how key it is to this recipe. While buying cheese that is pre-shredded is a great time saver, I argue that it isn’t one that is worth it. In order to keep the shreds separated before they make it to your kitchen, that cheese is coated in preservatives. Those same preservatives make it harder for it to melt. Taking the time to shred your own cheese is definitely worth it.

Substitutions and Variations

While you need to keep the amount of pasta and liquids the same, there are a few changes you can make without affecting things.

  • Mix up the vegetables. You could leave out the green pepper or swap it for a red bell pepper. You could also add an onion in here.
  • Make it vegetarian. Instead of using pork sausage, heat up 2 tablespoons of olive oil and sauté the green pepper and garlic with onions, some carrots, zucchini, and a second pepper. The proceed to step 3.
  • Switch up the meat. If you can’t find Italian sausage, you could substitute with ground beef or ground turkey and it would be fine. If you are using ground beef, you may need to drain off a little grease at the end of step 2.
  • Leave off the final toppings.The topping with pepperoni and olives at the end is totally optional. I think it adds something nice, but it is not necessary. If your family loves pepperoni, you could also chop some and stir it in before topping with cheese in step 5.

    My family enjoyed this one! They are picky eaters and skeptical of new recipes but this was definitely a hit so I’ll be saving it and making it again. Thank you!

    • Lisa Longley says

      I’m so happy to hear that!

  2. Tasha says

    Hello. Is there anything I can use in place of the crushed tomatoes?

    • Lisa Longley says

      Unfortunately, no. This recipe has only been tested with crushed tomatoes and because you are using that liquid to cook the pasta, it would need to go through more testing with a different ingredient (like chicken stock) to let you know how much to use.

  3. Jan says

    I have a lot of frozen bell peppers. Can I use these?

    • Lisa Longley says

      They might add a little extra liquid to the dish, but I can’t think of why it wouldn’t work.

    I did use frozen peppers I had in freezer. Worked fine. Hubby says this is a keeper. I did half the recipe for us two and got two meals for us.
