Best ways to enjoy it
Once your casserole is baked to perfection, consider serving it alongside a simple green salad or steamed vegetables for a well-rounded meal. You could even add a dollop of sour cream or a sprinkle of fresh herbs on top for an extra touch of flavor. This dish is flexible and pairs well with a variety of sides, making it a versatile choice for any dinner occasion.
Storage and reheating tips
For any leftovers, allow the casserole to cool completely before storing it in an airtight container in the refrigerator. It can stay fresh for up to 3–4 days. To reheat, simply pop it in the oven at 350°F for about 20 minutes or until heated through. If you want to freeze it, consider making the casserole but not baking it—freeze the unbaked casserole wrapped tightly in plastic wrap and foil for up to 3 months. Bake it directly from frozen, adding an extra 10–15 minutes to the cooking time.
Helpful cooking tips
To make this dish even creamier, consider using a mix of cream and sour cream for added tang. If you want a bit more crunch on top, you can mix in some crushed nuts or seasoned breadcrumbs with the panko. These little tweaks can elevate your casserole game while maintaining the classic flavors you love.
Creative twists
While this Chicken Cordon Bleu Casserole is delicious as is, don’t hesitate to get creative. Try adding in vegetables like spinach or broccoli for more nutrition. For a different flavor profile, swap the Swiss cheese for Gruyère or cheddar. These simple variations can allow you to make this dish feel fresh each time you serve it!
