Bring a large pot of salted water to a boil.

Add fettuccine pasta and cook according to package instructions until al dente.

While the pasta cooks, melt the butter in a large saucepan over medium heat.

Cook minced garlic in melted butter for 1-2 minutes until fragrant.

Stir in the heavy cream and bring the mixture to a gentle simmer.

Whisk in the Parmesan cheese until smooth. Thin the sauce with extra cream if needed.

Season the sauce with salt and black pepper to taste.

Drain the cooked pasta and add it to the sauce. Toss to combine.

Serve immediately. Garnish with fresh parsley if using.
