A quick and delicious casserole bringing together layers of rotisserie chicken, Swiss cheese, ham, and a creamy garlic Dijon sauce for homestyle comfort.
Preheat your oven to 350°F (175°C). This gets your dish ready for that golden brown finish.
Get a big skillet heated and melt 4 tablespoons of butter over medium heat. Toss in those minced garlic cloves and stir until you get that nice fragrant smell going.
Sprinkle in the flour and cook for about a minute to make a roux. This thickens the sauce real good.
Slowly whisk in the milk, making sure you don’t get lumps. Keep cooking until it thickens up like a creamy sauce.
Add lemon juice, Dijon mustard, and salt to your sauce. These little touches give it a nice tang and depth. Stir well so it’s all smooth.
Grab your greased 9x13 inch baking dish and layer half the shredded chicken. Then spread half the chopped ham and Swiss cheese on top in order. You gotta layer it just right for good texture in every bite.
Pour half the sauce over the layered ingredients. Then repeat with the remaining chicken, ham, Swiss cheese, and sauce. Get it all covered and ready for baking.
Bake the casserole for about 30 minutes until it’s bubbly and the top gets a golden brown crust. That’s when you know it’s good to go.
Notes
For a richer sauce, use half-and-half instead of milk. Consider using Gruyere cheese for a nuttier flavor or stick with Swiss for a classic taste.
