The Complete Chicken Cordon Bleu Casserole Recipe

This recipe serves 6‑8 people. It fits a 9×13 inch baking dish and can easily be doubled.

Ingredients – For the Casserole Base:

3‑4 boneless, skinless chicken breasts (about 1.5‑2 lbs / 680‑900g), cut into bite‑sized pieces

8 oz (about 8 slices) deli ham, chopped or torn into small pieces

8 slices Swiss cheese (or 2 cups shredded Swiss cheese)

2 cups cooked rice or pasta (optional base – see note)

Ingredients – For the Creamy Sauce:

1 cup (240ml) heavy cream or whole milk (heavy cream gives a richer sauce)

1 cup (240ml) low‑sodium chicken broth

4 oz (113g) cream cheese, softened and cut into cubes

1 tablespoon Dijon mustard

2 cloves garlic, minced

½ teaspoon salt

¼ teaspoon black pepper

¼ teaspoon nutmeg (optional, but traditional)

Ingredients – For the Crunchy Topping:

1 cup panko breadcrumbs (or crushed Ritz crackers)

2 tablespoons unsalted butter, melted

¼ cup grated Parmesan cheese

2 tablespoons fresh parsley, chopped (optional)

Equipment:

• 9×13 inch baking dish
• Non‑stick spray or butter
• Saucepan
• Whisk
• Mixing bowl

Step‑by‑Step Instructions

Step 1 – Preheat and Prepare the Dish

Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with non‑stick spray or butter. If using cooked rice or pasta as a base, spread it evenly in the bottom of the dish.

Step 2 – Layer the Chicken, Ham, and Cheese

Place the bite‑sized chicken pieces in an even layer over the rice (if using) or directly in the dish. Sprinkle the chopped ham over the chicken. Layer the Swiss cheese slices (or shredded Swiss) over the ham.

Step 3 – Make the Creamy Sauce

In a medium saucepan over medium heat, combine the heavy cream, chicken broth, cream cheese, Dijon mustard, minced garlic, salt, pepper, and nutmeg. Whisk constantly until the cream cheese is melted and the sauce is smooth and slightly thickened, about 5‑7 minutes. Do not let it boil. Remove from heat.

Step 4 – Pour Sauce Over Casserole

Pour the creamy sauce evenly over the layered casserole, making sure it seeps down between the chicken and ham.

Step 5 – Make the Crunchy Topping

In a small bowl, combine the panko breadcrumbs, melted butter, and grated Parmesan cheese. Mix until the crumbs are evenly coated. Sprinkle the topping evenly over the casserole.

Step 6 – Bake

Bake uncovered at 375°F for 30‑35 minutes, until the chicken is cooked through (internal temperature 165°F), the sauce is bubbly, and the topping is golden brown. If the topping is browning too quickly, tent loosely with foil for the last 10 minutes.

Step 7 – Rest and Serve

Let the casserole rest for 5‑10 minutes before serving. Garnish with fresh parsley if desired. Serve hot.

Pro Tips for the Best Chicken Cordon Bleu Casserole

Follow these expert tips for perfect creamy chicken casserole every time:

Use boneless, skinless chicken thighs for extra juiciness – Thighs are more forgiving and stay moist. Cut into bite‑sized pieces.

Do not skip the Dijon mustard – It adds a tangy depth that balances the richness and is essential to the cordon bleu flavor profile.

Use good quality Swiss cheese – Swiss cheese has a distinct nutty, mild flavor. Gruyère or Emmental are excellent substitutes.

Make it a complete meal – Serve over egg noodles, rice, or mashed potatoes. Or, add a side of steamed green beans or a simple salad.

For an extra‑creamy sauce, use heavy cream instead of milk – Heavy cream gives a richer, thicker sauce.

Add a pinch of nutmeg – Traditional cordon bleu often includes nutmeg; it enhances the creamy, cheesy flavor.

Let the casserole rest before serving – This allows the sauce to set slightly and makes serving easier.
