Cook pasta according to package directions. Drain and set aside.
Cube the leftover turkey.
Add 2 tablespoons of butter to the skillet, followed by the minced garlic.
Stir the garlic around the pan to avoid burning, and cook for 1 minute.
Pour in the broth, letting it bubble up and reduce for 1-1/2 to 2 minutes.
Add half-and-half, cream, and extra salt and pepper, whisking constantly until it's all combined. Allow liquid to heat up and thicken for a few minutes. (If it gets too thick, thin it with a little extra chicken broth.)
When sauce has thickened (a little), add Parmesan to the pan, and stir until melted.
Add the pasta and turkey, stir together, and let the skillet sit on low heat for 5-7 minutes, or until the turkey is heated through.
Top with minced parsley and extra Parmesan.
