Key Ingredients

Every great Pepperoni Pizza Casserole starts with the right balance of ingredients. Here’s what you’ll need to create this cheesy masterpiece:

Ground Beef or Italian Sausage: The base of the casserole that adds savory depth and a meaty bite. You can use one or a mix of both for extra flavor.

Low-Carb Marinara Sauce: Choose a sugar-free marinara or make your own with crushed tomatoes, garlic, oregano, and basil.

Pepperoni: The classic topping that gives that signature pizza flavor. Use high-quality slices for the best results.

Mozzarella Cheese: Melts perfectly for that gooey, stretchy texture that makes every bite irresistible.

Parmesan Cheese: Adds sharp, nutty flavor that balances the richness of the dish.

Bell Peppers and Onions: Add a touch of sweetness and crunch to complement the meat and cheese.

Olives or Mushrooms (Optional): Bring in more classic pizza toppings for extra variety.

Italian Seasoning: A must-have blend of oregano, basil, and thyme that ties all the flavors together.

Eggs (Optional for Structure): Helps the casserole hold together like a lasagna if you want a firmer texture.

Step-by-Step Instructions

Making this Pepperoni Pizza Casserole couldn’t be easier. Here’s how to do it:

1. Preheat the Oven: Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Cook the Meat: In a large skillet over medium heat, brown the ground beef or sausage until fully cooked. Drain excess fat and return to the skillet.
3. Add Sauce and Seasoning: Stir in marinara sauce, Italian seasoning, salt, and pepper. Simmer for 5 minutes to let the flavors blend.
4. Prepare the Layers: Spread half of the meat sauce evenly across the bottom of the casserole dish.
5. Add the Cheese: Sprinkle a layer of mozzarella and parmesan cheese over the meat mixture.
6. Add Toppings: Layer sliced pepperoni, bell peppers, onions, and olives (if using).
7. Repeat Layers: Add the remaining sauce, followed by another generous layer of cheese and more pepperoni on top.
8. Bake: Bake uncovered for 25–30 minutes or until the cheese is bubbly and golden brown.
9. Cool Slightly and Serve: Let it rest for 5 minutes before serving to help the layers set.

This dish comes out rich, cheesy, and loaded with the comforting flavors of pizza in every bite. The melted cheese stretches beautifully with every forkful, and the pepperoni crisps perfectly on top for that authentic pizzeria taste.
