Instructions

Preheat and prepare the baking dish: Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish to prevent sticking and ensure easy serving.
Mix the creamy base: In a large bowl, combine the softened cream cheese, sour cream, Dijon mustard, garlic powder, onion powder, salt, and black pepper. Mix until the texture is smooth and fully blended, creating a rich, flavorful sauce.
Add the proteins and cheese: Fold the shredded or cubed cooked chicken, diced ham, and 1 ½ cups of the shredded Swiss cheese into the creamy mixture. Gently combine to ensure everything is evenly distributed.
Assemble the casserole: Spread the mixed chicken, ham, and cheese filling evenly into the prepared baking dish, smoothing the top with a spatula.
Prepare the topping: In a small bowl, mix the crushed Ritz crackers with the melted butter until the crumbs are thoroughly coated and ready to form a golden crust.
Add topping and remaining cheese: Sprinkle the buttered cracker crumbs evenly over the surface of the casserole, then top with the remaining ½ cup of shredded cheese for extra cheesiness.
Bake: Place the casserole in the oven and bake for 25–30 minutes or until the casserole is heated through, bubbly, and the topping is golden brown and crisp.
Rest and garnish: Allow the casserole to cool for about 5 minutes after baking to set. Garnish with chopped parsley if desired, then serve warm for a comforting meal.

Notes

Rotisserie chicken is an excellent shortcut and works perfectly in this recipe.
For a low-carb option, omit the cracker topping or replace it with crushed pork rinds.
This casserole pairs wonderfully with a fresh green salad or steamed vegetables to balance the richness.
