How To Make Chicken Cordon Bleu Casserole
Ready to bake your way to cheesy comfort? In just a few simple steps, you’ll mix, layer, and crisp your casserole until it’s bubbling and golden. With each technique—from whisking the cream sauce to achieving that perfect breadcrumb crust—you’ll feel like a pro in the kitchen.
1. Preheat your oven to 350°F and grease a 9×13-inch baking dish with cooking spray or a light coat of butter.
2. In a large bowl, combine the shredded chicken, diced ham, and shredded Swiss cheese, tossing until evenly distributed.
3. In a separate bowl, whisk together the mayonnaise, sour cream, milk, Dijon mustard, garlic powder, onion powder, salt, and black pepper until smooth and creamy.
4. Pour the creamy mustard mixture over the chicken-ham blend, stirring until every piece is fully coated in that velvety sauce.
5. Transfer the combined filling into your prepared baking dish, spreading it into an even layer with a spatula.
6. In a small bowl, toss the panko breadcrumbs with the melted butter until all crumbs are well coated, then sprinkle the topping evenly over the casserole.
7. Bake for 25 minutes, or until the casserole is bubbling at the edges and the panko topping turns a beautiful golden brown.
8. Remove from the oven and let the casserole rest for 5 minutes before serving to allow the layers to set.

Frequently Asked Questions
Got questions? Let’s clear up any doubts so you can bake with confidence!
- How long does it take to prepare and cook this Chicken Cordon Bleu Casserole?
Preparation takes about 15 minutes, including shredding chicken, dicing ham, mixing the sauce, and greasing the dish. Baking requires 25 minutes at 350°F plus a 5-minute rest—for a total of around 45 minutes.
- Can I make this casserole ahead of time?
Yes. Assemble the casserole up to the breadcrumb topping, cover tightly, and refrigerate for up to 24 hours. When ready, sprinkle the topping and bake as directed.
- What substitutions can I use for the Swiss cheese and mayonnaise?
You can swap Gruyère for Swiss cheese to add a nuttier depth. Replace mayonnaise with an equal amount of Greek yogurt or light sour cream, keeping the total creamy volume the same.
- How can I achieve an extra-crispy breadcrumb topping?
After baking for 25 minutes, switch to broil, place the casserole about 6 inches from the heat source, and broil for 1–2 minutes until golden—watching closely to prevent burning.
- What’s the best way to store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. To reheat, cover with foil and warm at 350°F for 10–12 minutes, or microwave individual servings for 1–2 minutes.

- How can I adapt the recipe for dietary restrictions?
For gluten-free, use GF panko breadcrumbs and verify GF mayo and mustard. For lower fat, swap half the sour cream and mayo with low-fat yogurt. To reduce sodium, choose low-salt ham and Swiss cheese, and adjust added salt.
- Is it possible to scale this recipe for fewer or more servings?
Yes. For 3–4 servings, halve every ingredient and bake in an 8×8-inch dish for 20–22 minutes. To double, use two dishes or a larger pan, keeping 350°F and adding 5–10 extra minutes until bubbly and golden.
