🍳 Instructions

1. Preheat Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.

2. Make the Sauce

In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1 minute to form a roux. Slowly whisk in milk and chicken broth. Cook, stirring constantly, until thickened (about 5 minutes). Stir in Dijon mustard, garlic powder, onion powder, and season with salt and pepper. Remove from heat.

3. Assemble the Casserole

In the prepared baking dish, layer the cooked chicken evenly. Top with diced ham. Pour the sauce evenly over the meat, then sprinkle the Swiss and Parmesan cheese on top.

4. Add the Topping

In a small bowl, mix the panko breadcrumbs with melted butter and paprika. Sprinkle over the top of the casserole.

5. Bake

Bake uncovered for 25–30 minutes, or until bubbly and golden on top. Let sit for 5 minutes before serving. Garnish with parsley if desired.

🔁 Variation (From Me!)

🥦 Chicken Cordon Bleu Broccoli Casserole

Add 2 cups of steamed broccoli florets to the chicken layer for a complete meal in one dish. The green adds nutrition, color, and a bit of crunch.

🧠 Tips & Tricks

• Rotisserie chicken is a huge time-saver here.
• For a lower-fat version, use half milk, half chicken broth and skip the Parmesan.
• Want more cheese? Swap in Gruyère or provolone for a deeper flavor.
• Make it ahead: assemble the casserole and refrigerate, then bake when ready.
• Breadcrumbs too crispy? Cover loosely with foil for the first 20 minutes of baking.
