Gluten Free Chicken Cordon Bleu Casserole

Tender chicken, savory ham, and melty Swiss cheese layer together in one comforting baking dish, all blanketed in a silky, mustard-kissed sauce that gets its depth from a quick whisked base and a hint of thyme. The top turns golden and craggy as it bakes, giving every scoop that contrast of crisp topping against the rich, saucy layers underneath. A scatter of fresh parsley brightens the finished dish right before it hits the table. This casserole format makes the classic cordon bleu flavors easy to portion out for a weeknight dinner or a make-ahead crowd-pleaser, and it holds up beautifully for meal prep too. It's a solid pick to add to a gluten free dinner rotation, delivering that same cozy, cheesy, ham-and-chicken combination in a fraction of the effort of rolling and breading individual cutlets.

1 ½ cups swiss cheese, shredded

For the sauce

3 tbsp unsalted butter
3 tbsp all-purpose flour
Chef's tip
Choose a gluten-free baking blend labeled 1:1 or cup-for-cup and use the same amount. Almond and coconut flour won't work the same way.
2 cups low-sodium chicken broth
½ cup milk
1 tsp dijon mustard
¼ tsp dried thyme
¼ tsp salt

For the topping

½ cup breadcrumbs
Chef's tip
Panko flakes are larger and crispier than regular bread crumbs. Use the same amount for breading or crunchy toppings; crush it slightly first if the recipe needs fine crumbs for binding.
1 tbsp unsalted butter, melted

For serving

2 tbsp fresh parsley, finely chopped (optional)

Instructions

1
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2
Spread the chicken pieces in an even layer across the bottom of the prepared baking dish. Scatter the chopped ham evenly over the chicken, then sprinkle 1 cup of the shredded Swiss cheese over the top.
