Ingredient Swaps & Notes

• Rotisserie chicken works beautifully and saves time.
• Swap Gruyère for Swiss if you want a slightly nuttier flavor.
• Use panko breadcrumbs for extra crunch.
• For a lighter version, replace heavy cream with more milk (though it won’t be quite as rich).
• Add a pinch of paprika to the topping for subtle warmth.

Step-by-Step Instructions

1. Cook the Pasta

Boil egg noodles in salted water until al dente. Drain and set aside.

2. Make the Creamy Dijon Sauce

Melt butter in a saucepan over medium heat.
Whisk in flour and cook for about 1 minute to eliminate the raw flour taste.

Slowly add milk and heavy cream, whisking continuously until smooth and thickened.

Stir in Dijon mustard, garlic powder, salt, and black pepper. Remove from heat.

3. Assemble the Casserole

Preheat oven to 375°F (190°C).

In a large bowl, combine:

• Cooked pasta
• Diced chicken
• Diced ham
• Swiss cheese
• Mozzarella cheese
• Prepared sauce

Mix until everything is evenly coated. Transfer to a greased casserole dish.

4. Add the Topping

Mix breadcrumbs with melted butter and Parmesan cheese. Sprinkle evenly over the casserole.

5. Bake

Bake uncovered for 25–30 minutes, until bubbly and golden brown on top.

6. Garnish & Serve

Sprinkle with fresh parsley and let rest for 5 minutes before serving for cleaner slices.

Tips for Success

• Don’t overcook the pasta — it will continue cooking in the oven.
• Shred your own cheese for the best melt and texture.
• Let the casserole rest before serving so it firms up slightly.
• If the topping browns too quickly, loosely tent with foil.
