# How to Make It:
01 - Preheat oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
02 - Melt unsalted butter in a saucepan over medium heat. Add the diced onion and minced garlic, sautéing for 2 to 3 minutes until fragrant and softened.
03 - Whisk in all-purpose flour and cook for 1 minute to form a roux. Gradually add whole milk while whisking constantly, and continue to cook for 3 to 4 minutes until the mixture thickens slightly.
04 - Stir in Dijon mustard, kosher salt, black pepper, and smoked paprika. Remove the sauce from heat.
05 - In the prepared baking dish, arrange half of the cooked chicken, followed by all diced ham, then half of the shredded Swiss cheese. Repeat with remaining chicken and Swiss cheese.
06 - Pour the prepared sauce evenly over the layered ingredients.
07 - Combine Panko breadcrumbs and grated Parmesan cheese in a bowl. Sprinkle evenly over the casserole.
08 - Bake uncovered for 30 to 35 minutes until the topping is golden brown and the casserole is bubbling at the edges.
09 - Remove from oven and allow to rest for 5 minutes before serving.
# Expert Tips:
01 -
- This casserole brings all the classic flavors together without the fuss of rolling and breading chicken.
- The contrast of gooey cheese and crisp golden topping is every bit as comforting as you hope.
02 -
- Don’t rush sautéing the onions—they're where that comforting sweetness comes from.
- Letting the casserole sit before serving prevents it from collapsing into gooey chaos.
03 -
- Toast the Panko lightly in a pan first for even more crunch and flavor.
- Layer cheese close to the sauce so it melts beautifully and doesn’t dry out.
