Ingredients & Substitutions
Pasta: Since this is a spaghetti pizza casserole, I used spaghetti noodles as the base. Of course, you could certainly use the pasta you have on hand, or make your own homemade shaped pasta to use! After cooking and draining the pasta, be sure to let it cool a bit before mixing it with the egg.
Cheese: Use a little bit of mozzarella cheese in the base (with the pasta), as well as on top, just like a pizza! Or, try this recipe with different kinds of cheese.
Marinara Sauce: Choose your favorite brand of marinara sauce, or make your own. For a little kick to the dish, give an Arrabbiata sauce a try.
Meat: I used ground beef in the sauce. Other options would be ground turkey, ground pork, or ground chicken.
Pepperoni: Use as many slices of pepperoni as you prefer! The number I added is just a suggestion, but feel free to pile it on!
What to Serve with Spaghetti Pizza Casserole
There are a few delicious options to add to the table when serving this casserole. Here are a few of my favorites:
Can I Use a Different Sized Pan?
Yes, in fact, the recipe has been tested using both a 9-inch springform pan and a 9×13-inch baking dish. The 9-inch springform pan resulted in an impressive presentation; however, the 9×13-inch baking dish was found to be better proportioned and resulted in a dish that was less thick. Both options were delicious and perfect for serving spaghetti pizza casserole.
How to Store Spaghetti Pizza Casserole
If you have leftovers, store the casserole in the refrigerator to enjoy within the next few days. Or, for longer storage, freeze it.
To Refrigerate: First, let the casserole cool to room temperature. Next, cover the pan with plastic wrap or aluminum foil. Or, store the pieces in an airtight container. It will last in the refrigerator for up to 3 days. Reheat it in the oven for 20-25 minutes at 350°F.
To Freeze: Use a freezer-safe pan to prepare the casserole, then allow it to cool completely before wrapping it in plastic wrap or aluminum foil. Label and date the packaging to ensure freshness for up to 3 months in the freezer. To reheat, thaw the casserole in the refrigerator overnight and then bake it in the oven for 20-25 minutes at 350°F for the best results.
Spaghetti Pizza Casserole
