A comforting and creamy casserole that transforms leftover turkey into a delicious, crowd-pleasing meal with tender pasta, mushrooms, and a rich sauce.
For best sauce texture, stir constantly when making the roux to avoid lumps. Cook pasta al dente to prevent mushiness after baking. Use freshly grated Parmesan for better melting and flavor. If turkey is dry, add it towards the end of sauce simmering to soak up moisture. Breadcrumbs topping is optional but adds a nice crunch.
