Step 1

Cook pasta according to package directions until al dente. Drain the cooked pasta and set aside.

Step 2

Melt the butter in a Dutch/French oven over medium heat. Add the garlic to the pan and cook for about 2 minutes, until fragrant.

Step 3

Sprinkle the flour into the skillet and cook for 2 more minutes, until the mixture is golden brown. Pour in the chicken broth and heavy cream, and bring the mixture to a boil.

Step 4

Season with salt and pepper to taste, and add the mustard powder. Reduce the heat to medium-low and cook until slightly thickened, about 10-12 minutes.

Step 5

Remove the pot from heat and stir in the cooked pasta, chicken, ham, and Swiss cheese. Sprinkle Parmesan over the top.

Step 6

Bake in the oven at 400 degrees for 13-15 minutes. Broil for an extra 2-3 minutes for a golden-brown finish. Garnish with parsley, and serve.
