Spaghetti Pizza Casserole

Combining the hearty satisfaction of spaghetti with the irresistible allure of pizza, this Spaghetti Pizza Casserole is a weeknight dinner dream come true. It’s the kind of dish that brings comfort to the table while adding a playful twist that delights both kids and adults alike. With just a few pantry staples, this hybrid casserole layers bold pizza flavors over a foundation of cheesy, egg-bound pasta — essentially turning spaghetti into a crispy crust.

The inspiration for this dish stems from the classic problem of choosing between pasta and pizza. Instead of making that tough call, this recipe smartly unites both into one family-style bake. The cooked spaghetti is mixed with eggs and Parmesan, then baked into a firm base that mimics a deep-dish pizza crust. Once topped with marinara, gooey mozzarella, and classic pizza toppings like pepperoni, the result is a cheesy, satisfying main that feels familiar yet exciting.

Another highlight is its versatility. You can keep it traditional with pepperoni and mozzarella or load it up with vegetables like mushrooms, olives, or bell peppers for a vegetarian take. It’s an ideal dish for using up leftovers, customizing for picky eaters, or impressing at potlucks and casual dinners. Plus, it reheats beautifully, making it a solid meal prep option.

This casserole is fast enough for weeknights and fun enough for gatherings. Whether you’re feeding a crowd or looking for a new way to reinvent pasta night, this recipe delivers comfort and creativity in every bite.
