A comforting, creamy casserole featuring tender chicken, spaghetti, and a zesty, cheesy sauce with a kick of heat. It’s a hearty, crowd-pleasing meal perfect for weeknights or gatherings.
Use rotisserie chicken for a shortcut. Ensure pasta is al dente as it softens while baking. Adjust cayenne to control spice level. Casserole can be assembled ahead and refrigerated or frozen before baking.
