A comforting, creamy, and cheesy pasta casserole packed with chicken and broccoli, perfect for a hearty family meal.
Cook pasta al dente to prevent it from becoming mushy in the oven.
Shred your own cheese for a smoother melting sauce.
Don’t skip the Dijon mustard; it adds a subtle, delicious tang.
This casserole is great for using up leftover cooked chicken.
