Step 1

Prepare pasta according to package directions in salted water. Drain, reserving 1/2 cup cooking liquid; set cooked pasta aside.

Step 2

Heat butter in a large saucepan over medium. Add garlic, and cook 1 minute to release flavor. Stir in cream, and bring to a boil; simmer 5 minutes. Remove and discard garlic.

Step 3

Whisk in pepper and 1 1/2 cups of the cheese until smooth and creamy. Turn heat off stove. Toss together pasta, alfredo sauce, and remaining cheese until well combined. If mixture becomes too thick, add a little of the reserved cooking liquid at a time, tossing until desired consistency. Sprinkle with parsley; serve immediately.
