  • 1/2 cup unsalted butter, divided
  • 1/2 yellow onion, chopped
  • 2 garlic cloves, minced
  • 1/4 cup all-purpose flour
  • 3 cups chicken stock
  • 2 cups heavy cream
  • 2 cups cooked chicken, chopped
  • 1 1/2 cups ham, chopped
  • 1 pound spaghetti, cooked according to package directions
  • 3/4 cup Swiss cheese, grated
  • Kosher salt and freshly ground black pepper to taste
  • 1 cup Panko breadcrumbs
  • 1/2 cup Parmesan, grated


Step 1: Prepare the Ingredients

  1. Cook the Spaghetti:
    • Cook the spaghetti according to the package directions until al dente. Drain and set aside.
  2. Chop the Ingredients:
    • Chop the cooked chicken and ham into bite-sized pieces.
    • Finely chop the yellow onion and mince the garlic cloves.

Step 2: Make the Sauce

  1. Sauté the Onion and Garlic:
    • In a large skillet or saucepan, melt 1/4 cup of unsalted butter over medium heat. Add the chopped onion and sauté until soft and translucent, about 5 minutes.
    • Add the minced garlic and cook for another 1-2 minutes until fragrant.
  2. Make the Roux:
    • Sprinkle the all-purpose flour over the sautéed onion and garlic. Stir well to combine and cook for 1-2 minutes to eliminate the raw flour taste.
  3. Add the Liquids:
    • Gradually pour in the chicken stock while stirring constantly to avoid lumps. Add the heavy cream and continue to stir until the sauce is smooth and begins to thicken, about 5-7 minutes.

Step 3: Assemble the Casserole

  1. Combine the Ingredients:
    • Add the chopped cooked chicken and ham to the sauce, stirring to combine.
    • Add the cooked spaghetti and grated Swiss cheese to the sauce mixture. Stir until everything is well combined and the cheese is melted. Season with kosher salt and freshly ground black pepper to taste.
  2. Transfer to Baking Dish:
    • Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and transfer the pasta mixture into it, spreading it out evenly.

Step 4: Prepare the Topping

  1. Make the Breadcrumb Topping:
    • In a small bowl, melt the remaining 1/4 cup of unsalted butter. Add the Panko breadcrumbs and grated Parmesan cheese. Stir until the breadcrumbs are evenly coated with the melted butter.
  2. Add the Topping:
    • Sprinkle the breadcrumb mixture evenly over the top of the pasta.

Step 5: Bake the Casserole

  1. Bake:
    • Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the casserole is heated through.

Step 6: Serve

  1. Cool Slightly:
    • Allow the casserole to cool for a few minutes before serving.
  2. Serve:
    • Serve the Chicken Cordon Bleu Tetrazzini hot, garnished with fresh parsley if desired.
