Ingredients
Casserole Base
- 3 cups cooked chicken diced or shredded
- 1½ cups cooked ham chopped
- 1½ cups Swiss cheese shredded or Gruyère cheese
Cream Sauce
- 3 tbsp butter
- 3 cloves garlic minced
- 3 tbsp all-purpose flour
- 2 cups milk or half-and-half for richer sauce
- 1 tsp Dijon mustard
- ½ tsp salt
- ¼ tsp black pepper
Topping
- ¾ cup breadcrumbs or panko
- 2 tbsp butter melted
- ¼ cup grated Parmesan cheese optional
Instructions
- Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
- Spread the cooked chicken evenly across the bottom of the dish. Top with chopped ham, then sprinkle shredded cheese over the top.
- In a saucepan over medium heat, melt the butter. Add garlic and cook for about 30 seconds until fragrant.
- Whisk in the flour and cook for 1 minute. Slowly pour in the milk while whisking until smooth.
- Add Dijon mustard, salt, and black pepper. Simmer until the sauce thickens slightly.
- Pour the sauce evenly over the chicken and ham mixture.
- In a small bowl, combine breadcrumbs with melted butter and Parmesan cheese. Sprinkle over the casserole.
- Bake uncovered for 30–35 minutes, or until bubbly and golden on top.
- Let rest for 5 minutes before serving.
Notes
- Rotisserie chicken works well for quick prep.
- Gruyère adds a richer flavor, while Swiss keeps it mild and classic.
- For a lighter version, use milk instead of cream and reduce cheese slightly.
