Step 1

In a medium saucepan over medium heat, melt the butter. Then add the garlic, salt, pepper, garlic powder, and nutmeg and cook for 1 minute.

Step 2

Slowly add the heavy cream and bring to a rapid simmer, then reduce the heat to medium-low and gently simmer for 5 minutes.

Step 3

Remove from the heat and add the cheese a small amount at a time, whisking until completely melted and incorporated before adding the next batch.

Step 4

Return to the stovetop and cook on low for an additional 2 to 5 minutes, stirring constantly, until beginning to thicken.

Step 5

Toss with 1 pound of fettuccine pasta and serve immediately, garnishing with fresh parsley and additional pepper, if desired.
