Cook the fettuccine pasta according to package instructions. Drain and set aside.
In a saucepan over medium heat, melt the butter and sauté the garlic until fragrant.
Stir in the heavy cream and bring to a simmer.
Add the Parmesan cheese and Cajun seasoning, stirring until the cheese is melted and the sauce is smooth.
Season with salt and pepper to taste.
Toss the cooked fettuccine with the sauce until well coated.
Serve hot, garnished with chopped parsley.

Grate Parmesan fresh for the best melting quality. If the sauce becomes too thick, thin it with a splash of reserved pasta water.
