The Secret to the Best Pizza Casserole

The key to perfect crockpot pizza casserole is slightly undercooking the pasta before adding it to the slow cooker.

Since the pasta continues cooking in the crockpot, starting with fully cooked pasta can make it too soft or mushy.

Using a rich pizza sauce instead of plain tomato sauce also makes a huge difference. It creates that signature pizza flavor without needing lots of extra seasoning.

Layering the cheese instead of mixing it all together gives you those delicious melty cheese pockets throughout the casserole.

Best Toppings to Add

One of the best parts of this recipe is how customizable it is.

Popular additions include:

  • Sliced black olives
  • Bell peppers
  • Mushrooms
  • Cooked Italian sausage
  • Bacon crumbles
  • Jalapeños
  • Spinach
  • Red onions
  • Extra mozzarella
  • Crushed red pepper flakes

You can truly turn this into your favorite pizza in casserole form.

Freezer

Freeze cooled portions for up to 2 months.

Reheating

Reheat in the microwave or oven with a small splash of sauce to keep it moist and cheesy.

Common Mistakes to Avoid

Overcooking the Pasta

Always slightly undercook the pasta before adding it to the crockpot.

Using Too Much Liquid

Too much sauce or undrained tomatoes can make the casserole watery.

Skipping the Layers

Layering helps distribute cheese and flavor evenly throughout the dish.

Cooking Too Long

Since the ingredients are mostly pre-cooked, long cook times can dry it out or make the pasta mushy.
