Tips & Variations

For extra flavor, add a teaspoon of dried thyme or rosemary to the casserole mixture.
Use panko breadcrumbs for a crunchier topping.
Swap out the mayonnaise for Greek yogurt to lighten the dish without sacrificing creaminess.
Try adding a layer of sautéed mushrooms for an earthy twist.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or reheat the full dish in a 350°F (175°C) oven until heated through, about 15-20 minutes.

FAQs

Can I prepare this casserole in advance?

Yes, you can assemble the casserole a day ahead and keep it covered in the refrigerator. Bake it fresh when ready to serve, adding a few extra minutes to the baking time if needed.

What can I use if I don’t have Swiss cheese?

Gruyère or mozzarella cheese can be used as substitutes for Swiss cheese. They will provide a similar melt and flavor that complements the ham and chicken.
