Ingredients Needed

  • Pasta – Usually this recipe calls for penne pasta, but you can use any type of pasta.
  • Italian sausage – Choose ground sausage or replace with ground beef.
  • Ground beefLean ground beef, but you can use ground turkey as well.
  • Pepperoni – I personally love using mini pepperoni slices for this recipe, but you can also try turkey pepperoni for a healthier option.
  • Onion – Choose a small to medium sized onion, depending on how much you want. Swap for onion powder if necessary.
  • Pizza sauce – This can be switched with spaghetti sauce or, if you don’t like tomatoes, try alfredo sauce.
  • Italian seasoning – If you can’t find Italian seasoning at the store, you can also make it at home. 
  • Garlic Minced garlic is preferred, but swap with garlic powder or garlic salt if you don’t have minced. 
  • Shredded mozzarella cheese – If you don’t like mozzarella, try using cheddar or parmesan cheese.

What To Serve With Pizza Casserole Recipe

Since this simple recipe leans more towards the comfort food category, it’s a good idea to serve it with some lighter sides.

I like to go with a green salad topped with carrots, green peppers, tomatoes, cucumber, and red peppers or a crusty Italian bread.

How To Store Leftovers

If you want to make this easy dinner recipe ahead and store it for serving the next day, the best way is to bake according to the directions before placing it in an airtight container.

Store in the fridge for up to 3 days, but it also makes a great freezer meal, where it can be kept for 4 months.

For best results when reheating, simply take a serving out of the fridge or freezer and bake in a pressure cooker on a warm setting based on the cook time in the recipe. Make sure it’s heated thoroughly before serving.

A great cooking tip – if it seems a little dehydrated, you can add a small can of cream of mushroom soup slowly, pouring a little in and allowing it to be soaked up before re-assessing and adding more as needed.

Best Casserole Tips

  • For this pasta casserole, you can add any of your favorite pizza toppings and customize it for your family’s taste!
  • That means topping it with pepperoni, sausage, veggies like bell peppers, or even pineapple (for my Hawaiian pizza lovers out there). I also recommend serving with red pepper flakes or parmesan cheese, which are traditional staples for pizza.
  • Use a crockpot liner for easier clean up.
