Expert Tips

• Great recipe for leftover chicken or ham. If you have leftovers from a big holiday meal or just from weeknight cooking, this is the best recipe to make the next day that everyone will love!
• Use rotisserie chicken or ham steak for an easy store-bought solution. When were in a pinch during a busy week, these are the two ingredients we reach for at the grocery store that keep the prep time of this casserole at just 15 minutes!
• Add veggies if desired. Spinach or even sautéed mushrooms would be delicious in this casserole.
• Swap the cheese or use a blend. We love the flavor of classic Swiss with chicken cordon bleu, but you could also use mozzarella or provolone.
• Add some fresh or dried herbs for delicious flavor. You can add thyme or rosemary for some more herby flavor in each bite.
• Swap the cream of chicken soup with homemade. Make it from scratch if you desire. This recipe yields the equivalent to a 10.5 ounce can: Melt 3 tablespoons butter in a saucepan over medium heat. Whisk in ⅓ cup all-purpose flour and cook for 1 minute. Whisk in ⅓ cup milk and ⅓ cup chicken broth until well combined. Season with ¼ teaspoon onion powder and salt and pepper to taste. Stir and cook for 1-2 minutes or until thickened and creamy. We also have a great recipe for cream of mushroom soup!

Storage

Refrigerate any leftovers in an airtight container for up to 4 days. You can reheat the leftovers easily in the microwave or oven for a few minutes until warmed through.

Freeze the casserole as well to reheat at a later date or you can even assemble the bake in advance and freeze to serve at a later date; you just may need to bake it a little longer than the cook time in the recipe to make sure its cooked through.

Making this casserole in advance is easy! Assemble it a few hours before your guests arrive and store it in the fridge, then bake when you’re ready to serve. Wait and add the crumb topping right before baking.
