Chicken Cordon Bleu Casserole

My chicken cordon bleu casserole is a weeknight hero that’s creamy, cheesy, and ready in under 30 minutes! No pounding, rolling, or breading required here. Just layers of shredded chicken, cubed ham, and a rich cheese sauce topped with a perfectly golden breadcrumb crust. This easy chicken bake delivers all the indulgence of classic chicken cordon bleu in a fuss-free dinner my whole family loves!
Classic chicken cordon bleu can be a bit of a chore to make, but this casserole version is super easy. I used up leftover shredded cooked chicken, cubed ham, and plenty of delicious Swiss cheese to make this. The cheese sauce is super simple to cook in just a few minutes, and it makes this casserole so rich and moist. It’s so simple to layer everything together with a breadcrumb topping, and bake until hot and bubbly! Serve this chicken cordon bleu bake over rice or pasta for a heartier meal, or keep it low-carb and serve it by itself.
