Instant Pot Pizza Casserole is one of our favorite weeknight meals.
It is extremely easy to make and the entire family loves it! In fact, even the pickiest eater who does not like pizza crust asks for seconds every time!
But what I love most about this recipe is that it can be on the table in less than 30 minutes! And even quicker if you brown your meat prior to making this recipe.
Plus, you can customize the ingredients to whatever pizza toppings that you and your family enjoy.
Instant Pot Pizza Casserole Base
Just like our oven baked pizza casserole recipe, the base begins with meat and pasta.
Our family prefers to taste of Italian Sausage. However, you can also use hamburger, ground turkey or even ground chicken instead.
And as for the noodles, we always use Rotini noodles. First of all, they cook up perfectly.
But more importantly, the spirals of the noodles allow the pizza sauce, cheese and toppings to sit in grooves. Therefore, you get all the flavors of the pizza casserole in every bite!
However, if you don’t have Rotini noodles, you can still make this recipe. Just adjust the cooking time based on the instructions listed on the back of the box.
You will want to set your Instant Pot cook time to half the amount of cook time listed. And if there is a range for the cook time, use the lower number.
For instance, if the box says to boil the noodles for 8-10 minutes. The Instant Pot cook time will be 4 minutes.
Layer The Pizza Casserole Ingredients
Once you have your meat sauteed, add the spices and stir. This is the time to also add in green pepper or mushrooms if you are using them.
But the most important part of this recipe is that you must layer the remaining ingredients.
Just like when making Instant Pot Spaghetti, you do not want to stir your noodles or pasta sauce before cooking.
By doing so you risk the chance that your Instant Pot will give you a BURN notice while the Pizza Casserole is cooking.
This is because both the noodles and the tomato based pizza sauce can easily stick to the bottom of the pan.
Instead, just place the noodles evenly over the meat mixture. Then pour the sauce so that they cover the noodles.
The only time that you will stir noodles and sauce will be after the cooking process has been completed.
Adding The Cheese, Pepperoni, and Other Toppings
When the cook time is up, slowly release the pressure by moving the valve to the venting position.
Then remove the lid and stir in half of the cheese and all but 9 pieces of pepperoni (these will be saved for the topping).
Now is also the time to stir in any remaining cold toppings: olives, cooked bacon bits, pineapples, etc.
Once the pizza casserole ingredients have been mixed in, add the remaining cheese and pepperoni to the top.
Then close the lid for a few minutes to allow the cheese to melt.
It is that simple! Now this Instant Pot Pizza Casserole can be added to your weeknight menu!
