Description
This is comfort food at its finest. Chicken Cordon Bleu Casserole takes all the elegance of the traditional dish—crispy chicken, savory ham, and melty Swiss cheese—and turns it into an easy, family-friendly bake that you can throw together in under an hour. No pounding, rolling, or frying required. Just layer, bake, and dig into that creamy, cheesy goodness that hits all the nostalgic notes of the original but with none of the stress.
Ingredients
For the casserole:
3 cups cooked chicken, chopped or shredded (rotisserie works great)
1 1/2 cups diced cooked ham
1 1/2 cups shredded Swiss cheese (or Gruyère)
1/2 cup grated Parmesan cheese
For the sauce:
4 tablespoons unsalted butter
1/4 cup all-purpose flour
2 cups milk (whole or 2% preferred)
1 tablespoon Dijon mustard
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
Salt and black pepper to taste
For the topping:
1 cup panko breadcrumbs
2 tablespoons melted butter
1/2 teaspoon dried parsley (optional)
Instructions
Step 1: Make the Sauce
In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes to form a roux. Slowly whisk in the milk and continue to stir until thickened, about 3–5 minutes. Stir in the Dijon mustard, garlic powder, onion powder, salt, and pepper. Remove from heat and stir in half the Parmesan cheese until melted.
Step 2: Build the Casserole
Preheat your oven to 375°F. In a greased 9×13-inch baking dish, layer the chopped chicken on the bottom, followed by the diced ham. Pour the warm sauce evenly over the top, then sprinkle the shredded Swiss cheese and remaining Parmesan cheese over everything.
Step 3: Add the Topping
In a small bowl, mix the panko breadcrumbs with the melted butter and a pinch of parsley if using. Sprinkle evenly over the top of the casserole.
Step 4: Bake Until Golden and Bubbly
Bake uncovered for 25–30 minutes or until the top is golden brown and the casserole is bubbling around the edges. Let it rest for 5–10 minutes before serving to allow it to set up a bit.
Step 5: Serve and Enjoy
Scoop onto plates and serve with a simple side salad or some steamed veggies. It’s rich, creamy, and oh-so-satisfying.
Notes
Great with a side of roasted green beans or garlic butter broccoli
Serve over rice or egg noodles if you want to stretch it even further
