- 1 tablespoon olive oil
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon garlic powder
- 8 oz (225 g) cooked ham, diced
- 8 oz (225 g) Swiss cheese, shredded
- 2 tablespoons grated Parmesan cheese
- 2 tablespoons chopped fresh parsley, optional
- 2 tablespoons unsalted butter
- 2 garlic cloves, minced
- 1 cup (240 ml) heavy cream
- ½ cup (120 ml) low-sodium chicken broth
- 2 tablespoons Dijon mustard
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- ¼ cup (25 g) grated Parmesan cheese
- Preheat the oven: Heat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Season the chicken: Pat the chicken pieces dry and season with salt, black pepper, and garlic powder.
- Cook the chicken: Heat olive oil in a large skillet over medium-high heat. Add chicken in a single layer and cook for 6–8 minutes, turning occasionally, until lightly golden and cooked through.
- Prepare the sauce: Melt butter in a saucepan over medium heat.
- Add garlic: Stir in minced garlic and cook for 30–45 seconds, until fragrant.
- Add liquids: Pour in heavy cream and chicken broth. Whisk in Dijon mustard, onion powder, and black pepper.
- Simmer: Reduce heat to medium-low and simmer for 4–5 minutes, stirring frequently. The sauce should slightly thicken and coat the back of a spoon.
- Add Parmesan: Stir in Parmesan cheese and cook for another 1–2 minutes, until melted and smooth.
- Layer the casserole: Spread half of the cooked chicken into the baking dish. Add half of the diced ham and half of the shredded Swiss cheese.
- Repeat: Layer the remaining chicken and ham over the first layer.
- Add sauce: Pour the creamy Dijon sauce evenly over the chicken and ham.
- Top with cheese: Sprinkle the remaining Swiss cheese and Parmesan over the top.
- Bake: Place in the oven and bake at 375°F (190°C) for 20–25 minutes, until the casserole is bubbling around the edges and the cheese is melted and golden.
- Broil if desired: For a more deeply browned top, switch to broil for 1–2 minutes, watching carefully so the cheese doesn’t burn.
- Rest: Remove from the oven and let the casserole rest for 5–10 minutes before serving. This helps the sauce settle.
- Garnish: Sprinkle with fresh parsley and serve hot.
