Ingredients Breakdown and Tips

Casserole Layers

Shredded Cooked Chicken (5 cups)
Using pre-cooked chicken keeps this recipe efficient. Rotisserie chicken works beautifully, offering both moisture and flavor. You can also use leftover roasted or poached chicken.

Black Forest Ham (9 oz)
This style of ham adds subtle smokiness and savory depth. Slice it into strips so it distributes evenly across the casserole.

Swiss Cheese (8 oz)
Swiss cheese is essential for authentic Chicken Cordon Bleu flavor. Its mild nuttiness melts smoothly and balances the richness of the sauce. Gruyère can be used as a substitute for a slightly more pronounced flavor.

---

Creamy Dijon Sauce

Unsalted Butter (6 tbsp)
Forms the base of the roux and adds richness.

Dijon Mustard (1 tbsp)
This is the heart of the sauce. Dijon adds sharpness and complexity without overwhelming the dish.

Lemon Juice (optional)
Brightens the sauce and balances the creaminess.

Garlic Powder, Salt, Nutmeg, Cayenne
These subtle seasonings enhance the sauce without overpowering the main flavors. Nutmeg adds warmth, while cayenne brings gentle heat.

All-Purpose Flour (6 tbsp)
Thickens the sauce into a luscious, spoon-coating consistency.

Whole Milk (3 cups)
Whole milk provides the ideal richness. Lower-fat milk can be used but may result in a thinner sauce.

Topping

Panko Breadcrumbs (1½ cups)
Creates a crisp, golden topping that contrasts beautifully with the creamy layers below.

Softened Butter (4 tbsp)
Helps the panko brown evenly and adds flavor.

Parsley (optional)
Adds a pop of freshness and color before serving.

Step-by-Step Instructions

1. Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with nonstick spray to prevent sticking and ensure easy cleanup.

2. Build the Base Layer

Spread the shredded chicken evenly across the bottom of the dish. This forms the foundation of your Chicken Cordon Bleu Casserole and ensures every serving has plenty of protein.

3. Add the Ham

Scatter the ham strips evenly over the chicken. Try to distribute them well so the salty, smoky flavor reaches every bite.

4. Layer the Swiss Cheese

Arrange the Swiss cheese slices over the ham, overlapping slightly. This layer melts into a creamy blanket during baking.

5. Make the Dijon Cream Sauce

In a saucepan over medium heat, melt the butter. Whisk in the Dijon mustard, lemon juice (if using), garlic powder, salt, nutmeg, and cayenne.

Sprinkle in the flour and whisk continuously until a smooth paste forms. Cook for about 1 minute to remove the raw flour taste.

Slowly add the milk, about ¼ cup at a time, whisking constantly to avoid lumps. Continue cooking and whisking for 3–4 minutes until the sauce thickens.

6. Assemble the Casserole

Pour the sauce evenly over the cheese layer, spreading it gently into all corners of the dish.

7. Add the Topping

In a small bowl, combine the panko breadcrumbs with softened butter until evenly coated. Sprinkle the mixture over the casserole.

8. Bake

Bake uncovered for 30–40 minutes, until the sauce is bubbling and the topping is golden brown.

9. Rest and Serve

Let the casserole rest for 5 minutes before serving. This allows the sauce to set slightly for cleaner slices.

Pro Tips for the Best Chicken Cordon Bleu Casserole

• Use rotisserie chicken for maximum flavor and convenience.

• Add milk gradually when making the sauce to ensure a silky texture.

• Don’t skip resting time—it makes a noticeable difference in consistency.

• Broil briefly at the end for extra crunch, but watch closely.

• Season lightly at first; ham and cheese already add saltiness.

Spicy Twist
