Ingredients For Pizza Casserole
Ground beef: Provides a hearty base for the casserole, adding rich flavor and protein.
Marinara sauce: Adds a tangy and savory tomato flavor that ties the dish together.
Mozzarella cheese: Melts beautifully to create a gooey, cheesy topping.
Pepperoni slices: Adds a classic pizza flavor with a bit of spice.
Bell peppers: Adds a sweet and crunchy texture to the casserole.
Onions: Provides a savory depth of flavor and a bit of crunch.
Italian seasoning: A blend of herbs that enhances the overall flavor of the dish.
Technique Tip for This Recipe
When browning the ground beef, make sure to break it up into small, even pieces to ensure it cooks evenly. This will help the marinara sauce blend more thoroughly with the meat, creating a richer and more cohesive base for your pizza casserole. Additionally, sauté the bell peppers and onions for a few minutes before mixing them with the beef to enhance their flavors and soften their texture. This step can elevate the overall taste and mouthfeel of the dish.

How To Store / Freeze This Dish
- Allow the pizza casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
- Transfer the cooled casserole to an airtight container. If you don't have a container large enough, you can also use heavy-duty aluminum foil or plastic wrap to tightly cover the dish.
- Store the casserole in the refrigerator for up to 3-4 days. Make sure to label it with the date to keep track of its freshness.
- For longer storage, consider freezing the pizza casserole. Cut the casserole into individual portions for easy reheating later.
- Wrap each portion tightly with plastic wrap, then place them in a freezer-safe bag or container. This double-layer protection helps prevent freezer burn.
- Label the freezer-safe bag or container with the date and contents. The pizza casserole can be frozen for up to 2-3 months.
- When ready to enjoy, thaw the casserole in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor.
- Reheat the thawed pizza casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through. You can also reheat individual portions in the microwave, but be sure to cover them to retain moisture.
- If reheating from frozen, add an extra 10-15 minutes to the oven time, or use the defrost setting on your microwave before fully reheating.
