In a large pot, heat water over high heat until boiling. Add salt to the water. Once boiling, add fettuccine and cook according to package instructions.
In a large skillet, heat butter over medium heat. Add minced garlic and cook for 1 to 2 minutes, until fragrant. Stir in Ripple milk or heavy cream.
Let Ripple or heavy cream reduce and cook for 5 to 8 minutes. Add half of the parmesan cheese or dairy-free alternative of your choice to the mixture and whisk well until smooth. Keep over low heat until cheese has melted.
Toss Alfredo sauce with fettuccine pasta and add ½ cup of the parmesan cheese and toss the pasta.
Garnish with the remaining parmesan cheese and Italian parsley.
