Chicken Cordon Bleu Casserole
Chicken Cordon Bleu Casserole is a creamy, cheesy bake with tender chicken, savory ham, and Swiss cheese, finished with a golden breadcrumb topping—easy, comforting, and family-friendly.
Ingredients
For the casserole:
- 3 cups cooked chicken shredded or diced (rotisserie chicken works great)
- 1½ cups diced ham
- 2 cups shredded Swiss cheese or Swiss-mozzarella mix
- 1 cup 120g breadcrumbs (plain or seasoned)
- ¼ cup 30g grated Parmesan cheese
- 2 tablespoons melted butter
- 1 tablespoon chopped fresh parsley optional, for garnish
For the sauce:
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1½ cups 360ml milk
- ½ cup 120ml chicken broth
- 1 teaspoon Dijon mustard
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and pepper to taste
Instructions
- Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or nonstick spray.
- Melt 2 tbsp butter in a saucepan over medium heat. Whisk in flour and cook 1–2 minutes until bubbly. Gradually whisk in milk and broth; stir until smooth.
- Simmer 3–5 minutes until thickened. Add Dijon, garlic powder, onion powder, salt, and pepper. Remove from heat.
- Spread chicken in the baking dish, then layer ham on top. Pour sauce evenly over both.
- Sprinkle with Swiss cheese. In a bowl, mix breadcrumbs, Parmesan, and melted butter. Spread evenly over the cheese.
- Bake uncovered for 25–30 minutes until bubbly and golden. If browning too fast, tent with foil and continue baking.
- Let rest 5–10 minutes. Garnish with chopped parsley before serving.
