A playful mashup of spaghetti and pepperoni pizza baked into a sliceable pie. Al dente spaghetti is tossed with a rich tomato-meat sauce, eggs, and Parmesan, then baked until golden and topped with bubbling mozzarella and pepperoni.
Storage: Refrigerate leftovers in an airtight container for up to 3 days. Freezing: Wrap the fully baked and cooled pie tightly in plastic wrap and aluminum foil; freeze for up to 2 months. To reheat, thaw overnight in the fridge, then reheat individual slices in a 350°F (175°C) oven for 10-12 minutes or microwave on high for 1-2 minutes until heated through. If reheating a whole pie, cover with foil and bake at 350°F (175°C) for 20-25 minutes.
