Ingredients

Units Scale

For the casserole:

  • 4 cups cooked chicken, shredded or chopped (rotisserie works great)
  • 2 cups ham, diced
  • 2 cups Swiss cheese, shredded
  • 1 cup panko breadcrumbs
  • 1/2 cup Parmesan cheese, grated
  • 1 teaspoon dried parsley

For the sauce:

  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 1/2 cups milk
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon paprika
  • 1 tablespoon Dijon mustard

Instructions

  1. Preheat the oven and prepare the baking dish (5 minutes): Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or non-stick spray.
  2. Layer the chicken and ham (5 minutes): Spread the cooked chicken evenly at the bottom of the prepared baking dish. Layer the diced ham over the chicken, and then sprinkle 1 cup of the Swiss cheese over the ham.
  3. Prepare the sauce (10 minutes): In a saucepan over medium heat, melt the butter. Stir in the flour to create a roux, cooking for about 1 minute until bubbly but not browned. Gradually whisk in the milk, ensuring there are no lumps. Add salt, pepper, garlic powder, onion powder, paprika, and Dijon mustard. Continue to cook and stir until the sauce thickens, about 5-7 minutes.
  4. Combine the sauce with the casserole layers (2 minutes): Pour the creamy sauce evenly over the chicken, ham, and cheese in the baking dish.
  5. Add the final cheese and breadcrumb topping (5 minutes): Mix the panko breadcrumbs, Parmesan cheese, and dried parsley together. Sprinkle this mixture over the top of the casserole, then top with the remaining 1 cup of Swiss cheese.
  6. Bake the casserole (25 minutes): Bake uncovered in the preheated oven for 25-30 minutes, or until the topping is golden brown and the casserole is bubbly.
  7. Cool and serve (5 minutes): Let the casserole sit for about 5 minutes after removing it from the oven before serving. This allows the sauce to set slightly and makes serving easier.

Notes

Chicken cordon bleu casserole is a fantastic dish that captures all the elegance of the classic recipe but with the ease of a casserole.

For the best results, use good quality Swiss cheese and Dijon mustard, as these ingredients are key to the dish’s flavor.

This casserole can also be prepared ahead of time and refrigerated overnight, making it perfect for busy schedules—just add an extra 5-10 minutes to the baking time if starting from cold. Enjoy your meal!

Pair this with...

Maple Glazed Green Beans

Begin by trimming your fresh green beans. In a skillet over medium heat, add a splash of olive oil and sauté the beans until they're starting to soften but still have a bit of crunch. Meanwhile, in a separate pan, toast some pine nuts just until they're golden, which will bring out their rich, buttery flavor. Once the green beans are nearly done, drizzle in pure maple syrup to give them a sweet glaze that complements their natural earthiness. Let the syrup caramelize slightly and coat the beans. Add in your toasted pine nuts, toss everything together, and season with a pinch of salt.

Easy Dinner Rolls

Start by combining warm water, yeast, and a bit of sugar in a bowl, letting it sit until it's frothy. In a larger bowl, mix together softened butter, salt, the rest of your sugar, and some milk. Slowly add in flour, mixing until you have a soft dough. Knead this dough on a floured surface until smooth. Place it in a greased bowl, cover, and let it rise until doubled in size. Once risen, divide the dough into small balls and arrange them on a baking tray. Let them rise again briefly. Bake in a preheated oven until golden brown. Brush with melted butter right out of the oven for a glossy finish.

Honey Glazed Carrots

Begin by cleaning and peeling your carrots. If they're large, you might want to slice them into smaller, uniform pieces for even cooking. In a pan, bring a bit of water to a simmer and add the carrots, letting them steam until they're tender but still have a bite. Drain any excess water, then return the pan to the heat. Add a good dollop of butter and let it melt, followed by a generous drizzle of honey. Toss the carrots in this buttery, sweet mixture, seasoning with a pinch of salt and maybe a sprinkle of fresh thyme or parsley for an herbal touch. Let them cook a bit longer until they're beautifully glazed and glistening.
