Ingredients for Chicken Cordon Bleu Casserole

This casserole uses simple ingredients to create a rich and flavorful dish.

  • Chicken Breast (2 cups, cooked and shredded). Chicken is the base of this recipe, providing protein and a tender texture.

  • Ham (1 cup, diced). Ham adds a savory, salty flavor that gives this dish its classic cordon bleu taste.

  • Swiss Cheese (1½ cups, shredded). Swiss cheese melts beautifully and gives the dish its signature flavor.


  • Milk (½ cup). Helps thin the sauce for a smooth, creamy consistency.

  • Breadcrumbs (1 cup). Adds a crispy topping for texture contrast.

  • Butter (2 tablespoons, melted). Helps the topping become golden and crisp.

  • Dijon Mustard (1 tablespoon). Adds a subtle tang that enhances the flavor.

  • Salt and Pepper (to taste). Balances all the flavors.

How to Make Chicken Cordon Bleu Casserole

  1. Preheat the oven
    Preheat your oven to 375°F and prepare a baking dish.
  2. Prepare the filling
    In a bowl, combine shredded chicken, ham, and cheese.
  3. Make the sauce
    Mix cream of chicken soup, milk, Dijon mustard, salt, and pepper until smooth.
  4. Assemble the casserole
    Combine the filling with the sauce and spread evenly in the baking dish.
  5. Add topping
    Mix breadcrumbs with melted butter and sprinkle evenly on top.
  6. Bake
    Bake for 30–35 minutes until bubbly and golden brown.
  7. Serve
    Let cool slightly before serving.

Tips for the Best Chicken Cordon Bleu Casserole

  • Use rotisserie chicken for convenience. Rotisserie chicken saves time and adds extra flavor since it’s already seasoned. It’s one of the easiest ways to make this casserole come together faster on busy nights.
  • Don’t skip the Dijon mustard. Even a small amount of Dijon mustard makes a big difference. It adds a subtle tang that balances the richness of the cheese and cream sauce without overpowering the dish.
  • Use freshly shredded cheese. Pre-shredded cheese doesn’t melt as smoothly because of added anti-caking agents. Shredding your own Swiss cheese gives you a creamier, more consistent texture.
  • Bake uncovered for a crispy topping. Keeping the casserole uncovered allows the breadcrumb topping to turn golden and crisp instead of soft or soggy.
  • Mix breadcrumbs with butter evenly. Make sure the breadcrumbs and melted butter are fully combined so every bite gets that crispy, golden texture.
  • Let the casserole rest before serving. Letting it sit for 5–10 minutes after baking helps the sauce thicken and makes it easier to slice and serve cleanly.
  • Use a quality baking dish for even cooking. A well-made baking dish helps distribute heat evenly so the casserole cooks through without drying out or overbrowning on the edges.

  • 1 cup cooked ham diced
  • 2 10.5-oz can low-fat cream of chicken soup

  • 1 tbsp Dijon mustard

  • salt and ground black pepper to taste
  • 1 tsp garlic powder

Crispy Breadcrumb Topping (Optional but Highly Recommended)

  • ½ cup plain breadcrumbs or panko
  • 1 tbsp butter melted
  • 1 tbsp parmesan cheese grated, optional
  • ½ tsp garlic powder
  • salt and pepper to taste

Instructions
 

  • Preheat your oven to 375°F (190°C).Grease a 9×13 casserole dish lightly with cooking spray.
  • In a large mixing bowl, whisk together low-fat cream of chicken soup, Greek yogurt, dijon mustard, garlic powder, onion powder, salt & pepper. Mix until smooth and well-combined.
  • Spread half of the sauce in the bottom of the casserole dish.
  • Add chicken, ham, and then your preferred noodles (if using).
  • Sprinkle in your veggies — broccoli, mushrooms, peas — whatever you love.
  • Top with the rest of the sauce. Sprinkle shredded cheese evenly over the top.

For the crispy breadcrumb topping

    In a small bowl, mix breadcrumbs, melted butter, Parmesan (if using), garlic powder, salt, and pepper until evenly coated.

    • Sprinkle the breadcrumb mixture evenly over the casserole. If you want extra browning, broil for 1–2 minutes at the end, watching closely.
    • 💡 Tip:For an even lighter topping, reduce breadcrumbs to ⅓ cup and skip the butter—spritz lightly with cooking spray instead.
    • Cover with foil and bake for 25-30 minutes.
    • Remove foil and bake an additional 10-12 minutes until the cheese is melted and bubbly.
    • Let it sit for 5–10 minutes before serving — this helps the casserole set and makes slicing easier. Garnish with fresh parsley, cracked black pepper, or even a sprinkle of smoked paprika.
