Description

This Chicken Cordon Bleu Casserole transforms the classic dish into a cozy, layered bake featuring creamy Dijon sauce, Swiss cheese, tender chicken, and a crispy breadcrumb topping.


Ingredients

  • 5 cups shredded cooked chicken
  • 8 ounces sliced Swiss cheese (about 12 thin slices)
  • 6 tablespoons unsalted butter
  • 1 tablespoon Dijon mustard
  • 1 tablespoon freshly squeezed lemon juice (optional)
  • 1 teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon nutmeg (optional)
  • ¼ teaspoon cayenne pepper (optional)
  • 6 tablespoons all-purpose flour
  • 3 cups whole milk
  • 1½ cups Panko breadcrumbs
  • 4 tablespoons unsalted butter, softened
  • Chopped parsley (optional, for garnish)

Instructions

  1. Preheat the oven to 350°F (175°C) and spray a 9x13-inch casserole dish with nonstick cooking spray.
  2. Spread the shredded chicken evenly in the prepared dish.
  3. Layer the Swiss cheese slices over the chicken, overlapping as needed.
  4. In a saucepan over medium heat, melt the butter. Stir in Dijon mustard, lemon juice (if using), garlic powder, salt, nutmeg (if using), and cayenne pepper (if using).
  5. Add the flour and whisk until a smooth paste forms.
  6. Gradually whisk in the milk, about ¼ cup at a time, until smooth.
  7. Simmer the sauce for 4 minutes, whisking occasionally, until it thickens.
  8. Pour the sauce evenly over the cheese layer in the casserole dish.
  9. In a small bowl, mix the Panko breadcrumbs with the softened butter. Sprinkle this mixture evenly over the casserole.
  10. Bake uncovered for 30–40 minutes, until bubbly and golden on top.
  11. Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley if desired.

Notes

  • Use rotisserie chicken for quicker preparation.
  • Add steamed broccoli or sautéed mushrooms for extra nutrition.
  • Swap Swiss cheese with Gruyère or provolone for variation.
  • Use gluten-free flour and breadcrumbs for a gluten-free version.
