A quick and easy chicken spaghetti casserole with creamy sauce, tender shredded chicken, and melty cheddar cheese, perfect for busy weeknights and comforting family dinners.
Do not overcook the pasta initially; cook al dente to avoid mushy noodles after baking. Season the creamy base to taste. You can assemble ahead and refrigerate before baking, adding a few extra minutes to baking time if baking cold. For gluten-free, swap spaghetti with gluten-free pasta. For dairy-free, substitute sour cream and cheese with dairy-free alternatives.
