Creating Chicken Cordon Bleu Pasta Bake is simple if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

2. Cook the Pasta: In a large pot of salted boiling water, cook the penne pasta according to package instructions until al dente. Drain and set aside.

3. Combine Chicken, Ham, and Cheese: In a large bowl, combine shredded chicken, chopped ham, Swiss cheese, and mozzarella cheese.

4. Mix Sauce Ingredients: In another bowl, mix together heavy cream, chicken broth, sour cream, garlic powder, onion powder, dried parsley, salt, and pepper. Stir until smooth.

5. Combine Ingredients: Add the drained pasta to the chicken and cheese mixture. Then, pour the sauce over the top and mix well until everything is evenly coated.

6. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it out evenly.

7. Prepare the Topping: In a small bowl, combine the breadcrumbs with melted butter. Mix until the breadcrumbs are evenly coated.

8. Add Topping: Sprinkle the breadcrumb mixture over the pasta bake, ensuring it’s evenly distributed.

9. Bake: Place the baking dish in the preheated oven and bake for 30-40 minutes, or until the top is golden brown and bubbly.

10. Cool and Serve: Remove from the oven and allow it to cool for about 5-10 minutes before serving.
