In a medium pot, cook the pasta according to package directions. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the garlic and cook for 1 minute until it smells delicious.
Add the chicken broth and cream, and bring to a gentle boil. Let it bubble for 7-9 minutes until reduced in volume by about 60%.
Remove from the heat and stir in the Parmesan cheese until melted. Add the pasta and toss until combined. If the sauce is still runny, gently cook over medium heat until thickened.
