How to Make Chicken Cordon Bleu Casserole

Assemble the casserole: Transfer the mixture into the prepared baking dish and spread it into an even layer.
Prepare the topping: In a small bowl, mix together Panko breadcrumbs and melted butter. Sprinkle this mixture evenly over the top of the casserole.
Bake: Place the casserole in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and the casserole is bubbling.
Serve: Remove from the oven and let it rest for 5 minutes before serving. Garnish with freshly chopped parsley if desired.

Recipe Tips for the Best Chicken Cordon Bleu Casserole

Don’t overmix the filling: Stir gently to keep the chicken and ham pieces intact and prevent the casserole from becoming too dense.
