FAQs

What is Chicken Cordon Bleu?

Chicken Cordon Bleu is a traditional dish made with chicken, ham, and Swiss cheese, typically rolled, breaded, and fried or baked. This casserole simplifies the process with the same flavors in a layered format.

Can I make this casserole ahead of time?

Yes! Assemble the casserole (including the topping), cover, and refrigerate for up to 24 hours. Bake when ready to serve.

What’s the best type of chicken to use?

Rotisserie chicken, leftover roasted chicken, or poached chicken all work well. Just make sure it’s cooked and shredded or diced.

Can I use another type of mustard?

Dijon is best for its sharp, balanced flavor, but whole grain or spicy brown mustard can be used for a different taste.

What sides go well with this casserole?

Try a green salad, roasted vegetables, steamed green beans, or garlic mashed potatoes.

Can I make this dish lighter?

Yes, use low-fat milk and omit the heavy cream, or replace with more milk for a lighter sauce. Reduce cheese if desired.

Is this kid-friendly?

Absolutely. The creamy sauce and cheesy topping are generally a hit with kids. Reduce the mustard slightly if needed.

How can I make the sauce thicker?

Let it simmer an extra minute or increase the flour slightly for a thicker consistency.

Can I use deli ham?

Yes, just chop it finely. Thicker diced ham adds more texture, but deli slices work in a pinch.

Is this casserole freezer-friendly?

Yes, it freezes well either before or after baking. Use a freezer-safe container and label with the date for best results.

Description

This Chicken Cordon Bleu Casserole is a cozy, deconstructed take on the elegant French classic—perfect for busy weeknights or easy entertaining. Juicy shredded chicken and smoky ham are layered with melty Swiss cheese and smothered in a velvety Dijon cream sauce. Finished with a buttery, golden breadcrumb topping, this baked casserole delivers all the savory, cheesy comfort of traditional Chicken Cordon Bleu—without the fuss of rolling and frying.

Instructions

Preheat the oven: Set your oven to 375°F (190°C). Lightly grease a medium baking dish (8×8 or similar size).
Make the sauce: In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes, stirring constantly, until the mixture is lightly golden and fragrant.
Build the cream base: Slowly whisk in the milk and cream until smooth. Stir in Dijon mustard, garlic powder, salt, and black pepper. Cook for 3–4 minutes, whisking frequently, until the sauce thickens to a creamy consistency. Remove from heat.
Layer the casserole: In the prepared baking dish, evenly layer the cooked chicken, diced ham, and shredded Swiss cheese.
Pour and coat: Pour the warm Dijon cream sauce over the top, spreading evenly to cover all the meat and cheese.
Add the topping: In a small bowl, mix the Panko breadcrumbs with melted butter and Parmesan (if using). Sprinkle over the top of the casserole for a crisp, golden finish.

Bake and serve: Bake uncovered for 25–30 minutes, or until bubbly around the edges and golden on top. Let rest for 5 minutes before serving.

Notes

Use rotisserie chicken for a quick prep shortcut.
Add a layer of steamed broccoli or spinach beneath the chicken for a veggie boost.
Make it gluten-free by using GF flour and breadcrumbs.
