Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 375°F (190°C). While the oven is heating up, take a 9×13-inch baking dish and generously grease it with cooking spray or butter to ensure easy serving later. This Chicken Cordon Bleu Casserole will need a snug home in the oven where it can bubble and brown perfectly.
Step 2: Layer the Chicken and Ham
Take your shredded cooked chicken and spread it evenly across the bottom of the greased baking dish. Next, sprinkle the diced cooked ham on top, ensuring an even distribution. The combination of tender chicken and savory ham is the heart of your Chicken Cordon Bleu Casserole, creating layers of flavor that will meld beautifully during baking.
Step 3: Whisk the Creamy Mixture
In a medium bowl, whisk together the whole milk, softened cream cheese, Dijon mustard, garlic powder, salt, and black pepper until the mixture is smooth and well-combined. This creamy sauce is what ties the casserole together; it will envelop the chicken and ham with rich flavor. Pour this mixture evenly over the chicken and ham layers, creating a luscious base.
Step 4: Add the Cheese
Now it’s time to elevate your Chicken Cordon Bleu Casserole with cheese! Sprinkle the shredded Swiss cheese generously on top of the creamy mixture. As it bakes, this cheese will melt into a gooey, flavorful blanket, enhancing the casserole’s comforting essence while providing that cheesy goodness everyone loves.
Step 5: Prepare the Crunchy Topping
In a small bowl, mix the melted butter with the panko breadcrumbs until the crumbs are fully coated. This buttery mixture will provide a delightful crunch. Sprinkle the buttery panko evenly over the cheese layer. The contrast between the creamy filling and golden, crispy topping is what makes this casserole irresistible.
Step 6: Bake to Perfection
Place the baking dish in your preheated oven and bake the casserole uncovered for 30–35 minutes. You’ll know it’s ready when the edges are bubbly, and the top is a gorgeous golden brown. Allow your Chicken Cordon Bleu Casserole to cool for about 5 minutes after removing it from the oven; this will help the flavors settle and prevent burns while serving.

Storage Tips for Chicken Cordon Bleu Casserole
Fridge: Store any leftovers in an airtight container for up to 3 days. The flavors actually improve as they meld together, making each bite even more delicious!
Freezer: If you want to enjoy this Chicken Cordon Bleu Casserole later, freeze it before baking. Wrap it tightly in plastic wrap and aluminum foil—it can stay in the freezer for up to 2 months.
Reheating: To reheat, thaw the casserole in the fridge overnight, then bake at 350°F (175°C) for about 25 minutes until warmed through and bubbly. Add a sprinkle of fresh breadcrumbs on top for extra crunch!

Chicken Cordon Bleu Casserole Recipe FAQs
What should I look for when selecting chicken for this casserole?
Absolutely! When picking chicken for your Chicken Cordon Bleu Casserole, choose cooked chicken that is moist and flavorful. I often opt for a rotisserie chicken for convenience, ensuring it’s still warm and tender. Look for chicken breast without dark spots or uneven textures, as these can indicate aging or spoilage.
How should I store leftovers of the casserole?
You can store any leftovers in an airtight container in the fridge for up to 3 days. This allows the flavors to meld and develop as they sit. Just make sure it’s cooled down before sealing it to avoid condensation. Reheating in the oven helps maintain its crispy topping!
Can I freeze Chicken Cordon Bleu Casserole, and how do I do it?
Definitely! If you want to freeze your casserole, do it before baking. Wrap it tightly in plastic wrap and then with aluminum foil to prevent freezer burn. It can stay in the freezer for up to 2 months. When you’re ready to enjoy it, thaw it in the fridge overnight and then bake at 350°F (175°C) for about 25 minutes until heated through and bubbling.
What if the casserole turns out too salty?
Very common question! If you find your casserole overly salty, it could be due to the ham. To balance it out, consider adding more cream cheese or even a splash of unsweetened yogurt to the creamy mixture before baking. This helps tone down the saltiness, plus it adds a delicious creaminess!
Are there any dietary considerations for this casserole?
Of course! For those with lactose intolerance, substitute cheeses and dairy with lactose-free options, and using coconut cream can add a rich texture as well. As for pets, be careful with leftovers; while chicken and ham are generally safe in moderation, avoid sharing any cheesy or seasoned portions with your furry friends to prevent digestive issues.
