Step‑by‑Step Instructions for Chicken Cordon Bleu Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While it heats up, grease a 9×13-inch baking dish with cooking spray or a little melted butter to prevent sticking. This ensures that the Chicken Cordon Bleu Casserole will slide out easily when it’s ready to be served, keeping your presentation neat and appetizing.
Step 2: Layer the Chicken and Ham
Next, evenly spread the cooked, shredded chicken breast across the bottom of your greased baking dish. Take your diced cooked ham and sprinkle it generously over the chicken layer. The combination of these two meats forms a hearty base that embodies the classic flavors of chicken cordon bleu in casserole form.
Step 3: Prepare the Creamy Sauce
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 key to achieving that rich texture. Pour it evenly over the layered chicken and ham, making sure to cover all the pieces for ultimate flavor infusion.
Step 4: Add the Cheese Layer
Take your shredded Swiss cheese and evenly layer it on top of the creamy sauce. This cheesy layer not only adds flavor but will also create that deliciously gooey texture we all love in a Chicken Cordon Bleu Casserole. The cheese will melt beautifully during baking, binding all the ingredients together.
Step 5: Create the Crunchy Topping
In a small bowl, combine the panko breadcrumbs with the melted butter, mixing well to ensure each breadcrumb is coated. Sprinkle this buttery breadcrumb mixture evenly over the cheesy layer. This topping will turn golden brown and crispy as it bakes, adding a delightful contrast to the creamy interior of the casserole.
Step 6: Bake to Perfection
Place the assembled casserole in the preheated oven and bake uncovered for 30-35 minutes. Keep an eye on it during the last few minutes; the casserole is ready when it’s bubbly and the top is golden brown. This enticing aroma filling your kitchen is a sure sign that your Chicken Cordon Bleu Casserole is almost done.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and allow it to cool for about 5 minutes before serving. This short resting period helps the layers set slightly, making it easier to serve and preventing burns from the hot cheese. Now it’s time to dig into your warm, comforting Chicken Cordon Bleu Casserole!

Make Ahead Options
These Chicken Cordon Bleu Casserole is perfect for meal prep enthusiasts! You can prepare all the layers up to 24 hours in advance by assembling the casserole in your greased baking dish, covering it tightly with plastic wrap, and refrigerating.

When you’re ready to serve, simply remove the casserole from the fridge, let it sit at room temperature for about 20 minutes, then bake as directed (30-35 minutes at 375°F (190°C)). This way, you’ll have a comforting dinner ready with minimal last-minute effort!

What should I do if my casserole ends up too salty?
