This chicken spaghetti casserole is super easy to make, is loaded with deliciously seasoned chicken, spaghetti noodles, a scrumptious sauce, and lots of cheese.
If you know me, you know I love casseroles. I make casseroles for almost any occasion, from a weeknight dinner to potlucks and holiday get-togethers. If a casserole can be made, I’m probably the one to make it. I just love them. Sure, they’re easy to make, but there’s so much more to them. When people see a casserole, they see comfort. They know they’re about to eat something delicious that’s all about flavor and not being fancy. Casseroles are dishes of both flavor and nostalgia because we’ve all grown up with them. So I take every opportunity I can to make them.
Over the years, I’ve made all kinds of casseroles, but one of my favorites is this chicken spaghetti casserole. It’s so different from the normal creamy, potato-based casseroles that most of us know. It’s the perfect marriage of spaghetti and casserole that comes together into one dish that is full of flavor and all the feels.

One bite and you’ll be hooked.

The addition of the chicken is what really makes this casserole pop for me.
