How to Make Chicken Cordon Bleu Casserole

1
Preheat your oven to 375 F (190 C).

3
Add the minced garlic and cook for an additional 1-2 minutes, until fragrant.

In the same skillet, add the remaining 1 tablespoon of butter. Add the sliced ham and cook until it's lightly browned and crispy, about 3-5 minutes.
6
In a large bowl, combine the cooked chicken, ham, Swiss cheese, breadcrumbs, thyme, paprika, salt, and pepper. Mix well until all the ingredients are fully incorporated.
7
In a separate bowl, whisk together the melted butter and chicken broth. Pour the mixture over the chicken and ham mixture, and stir until everything is well coated.
