How to Make Chicken Cordon Bleu Casserole

Prep the Casserole

1. Preheat oven to 350°F (175°C).
2. Spray a 9×13-inch casserole dish with nonstick cooking spray.
3. Evenly spread shredded chicken into the dish.
4. Layer ham strips over the chicken.
5. Place Swiss cheese evenly on top, overlapping slices as needed.

Make the Creamy Sauce

1. Melt butter in a saucepan over medium heat.
2. Whisk in Dijon mustard, lemon juice (if using), garlic powder, salt, nutmeg (if using), and cayenne pepper (if using).
3. Sprinkle in flour and whisk until it forms a smooth paste.
4. Slowly add milk, a quarter cup at a time, whisking after each addition until smooth.
5. Simmer for 4 minutes until sauce thickens.

Tip: Whisk constantly to prevent lumps and ensure a smooth sauce.

Assemble & Add Topping

1. Pour the sauce evenly over the cheese layer, spreading into corners.
2. In a small bowl, combine Panko breadcrumbs and softened butter.
3. Spread the breadcrumb mixture evenly over the casserole.

Bake the Casserole

1. Bake uncovered for 30–40 minutes, until sauce is bubbling and Panko topping is golden brown.
2. Remove from oven and let rest 5 minutes before serving.
3. Sprinkle with chopped parsley if desired.

Tip: Resting helps the sauce set and makes slicing cleaner.

Tips for Success

• Ensure Panko topping is golden for maximum crunch.
• Use freshly shredded chicken for the best texture and flavor.
• Adjust seasoning in the sauce to your preference.
• Let casserole sit a few minutes before serving to avoid watery slices.
