Cordon Bleu Casserole

I often roast a turkey just to have leftovers for this creamy casserole. It makes for a pretty presentation at potluck dinners.—Joyce Paul, Qu'Appelle, Saskatchewan
  • Total Time
    Prep: 25 min. Bake: 25 min.
  • Makes
    6 servings


  • 2 cups cubed fully cooked ham
  • 4 cups cubed cooked turkey
  • 1 cup shredded Swiss cheese
  • 1 large onion, chopped
  • 1/3 cup butter, cubed
  • 1/3 cup all-purpose flour
  • 1/8 teaspoon ground mustard
  • 1/8 teaspoon ground nutmeg
  • 1-3/4 cups 2% milk
  • 1-1/2 cups soft bread crumbs
  • 1/2 cup shredded Swiss cheese
  • 1/4 cup butter, melted


  • In a large nonstick skillet, cook ham until browned, 4-5 minutes; drain and pat dry. In a greased 2-qt. baking dish, layer the turkey, cheese and ham; set aside.
  • In a large saucepan, saute onion in butter until tender. Stir in the flour, mustard and nutmeg until blended. Gradually stir in milk. Bring to a boil; cook and stir until thickened, about 2 minutes. Pour over ham.
  • Combine topping ingredients; sprinkle over the top. Bake, uncovered, at 350° until golden brown and bubbly, 25-30 minutes.
Editor's Note
To make soft bread crumbs, tear bread into pieces and place in a food processor or blender. Cover and pulse until crumbs form. One slice of bread yields 1/2 to 3/4 cup crumbs.

    This was excellent. I especially liked the crumb topping. I used chicken because that's what I had on hand and I thought it was more authentic for cordon bleu anyway. I will make this again for sure.

    Great recipe. One thing I do is add about 1/4 cup white wine to the sauce to give it a more authentic cordon bleu flavor. Yummy!

    Made this last night. Yummy! Made it with cooked chicken, but other than that exactly as instructed. May cut amount of onion, some bites a little overpowering. Definitely a keeper & comfort food on a rainy/snowy night.

    The dish is a keeper. We substituted turkey in the recipe and enjoyed it. The breadcrumbs were yummy. My one qualm was the onion really overpowered it. We'll cut that in half next time and enjoy it more.
