Chicken Cordon Bleu Casserole — Comfort, Creaminess & Classic Flavor

by

Introduction

Chicken Cordon Bleu is a beloved classic — chicken, ham, and Swiss cheese all wrapped up in a creamy, cheesy sauce. This casserole version captures all that rich, indulgent flavor but in a much easier format. There’s no need to roll chicken breasts or deep fry anything: you layer cooked chicken and ham, pour over a luscious creamy sauce, top with cheese and breadcrumbs, then bake until bubbly and golden. The result is warm, hearty, and perfect for family dinners or potlucks.

Ingredients (Approximate, based on classic versions)

  • Cooked chicken, shredded or cubed
  • Deli ham, diced
  • Swiss cheese, shredded
  • Butter
  • Flour (for the sauce)
  • Milk (or a mix of milk and broth)
  • Dijon mustard (adds depth and slight tang)
  • Garlic powder
  • Salt and pepper
  • Baby spinach (optional, for extra greens)
  • Panko breadcrumbs or regular breadcrumbs
  • Melted butter (for topping)
  • Fresh parsley (for garnish)

Step-by-Step Instructions

  1. Preheat the Oven
    Preheat your oven to around 350-375°F (175-190°C) depending on how thick your casserole will be.
  2. Layer the Base
    In a greased baking dish, place a layer of cooked chicken. Add a layer of diced ham on top. Then sprinkle with shredded Swiss cheese. Repeat if you have a deep dish and enough ingredients.
  3. Make the Creamy Sauce
    In a saucepan, melt butter over medium heat. Add the flour and whisk constantly to form a smooth roux.
    Slowly whisk in milk (or milk + broth) until the mixture becomes thick and smooth.
    Stir in Dijon mustard, garlic powder, salt, and pepper. Taste and adjust as needed.
    (Optional) If you’re using spinach, add it now and cook until wilted in the sauce.
  4. Assemble
    Pour the sauce evenly over the layers of chicken, ham, and cheese in the baking dish. Make sure everything is well coated.
  5. Add the Crunchy Topping
    In a small bowl, mix the breadcrumbs (Panko works great) with melted butter. Sprinkle this crumb mixture generously over the top of the casserole.
  6. Bake
    Bake in the preheated oven for 25-40 minutes, until the casserole is hot and bubbly and the breadcrumb topping is golden and crisp.
  7. Rest & Serve
    Let the casserole rest for a few minutes once it’s out of the oven. This helps the sauce thicken slightly and makes it easier to serve. Garnish with fresh parsley for color and freshness.

Tips for Success

  • Use leftover or rotisserie chicken to save time.
  • If your sauce gets too thick, thin it with a little more milk or broth before pouring.
  • For a richer flavor, use whole milk or a mix of milk and cream.
  • Toasting the breadcrumbs slightly before mixing with butter gives an extra crunchy texture.
  • Let it rest before cutting — this allows the sauce to set a bit so servings hold together.

Variations & Options

  • Veggie boost: Add peas, spinach, or broccoli into the chicken and ham layers.
  • Cheese variation: Use Gruyère, Monterey Jack, or a mix of cheeses instead of just Swiss.
  • Mustard twist: Use whole grain mustard or a blend for a tangy kick.
  • Gluten-free: Use gluten-free flour for the sauce and gluten-free breadcrumbs.
  • Low-carb: Skip the breadcrumbs topping or use crushed pork rinds instead.

Frequently Asked Questions (FAQ)

Q: Can I make this casserole ahead?
A: Yes — you can assemble everything, cover, and refrigerate. Bake when you’re ready, adding a few extra minutes if it’s cold from the fridge.

Q: How do I reheat leftovers?
A: Reheat gently in the oven at a low temperature (e.g., 325°F) until warmed through. You can also microwave individual servings, but you may lose some crispiness.

Q: Can I freeze it?
A: Yes — once baked and cooled, you can wrap the casserole tightly and freeze. Thaw overnight in the fridge and reheat in the oven for best texture.
