This rich and creamy homemade alfredo sauce is delicious on a bed of pasta, in a white lasagna, or on pizza. Best of all it's only a few simple ingredients and can be done in around 15 minutes.
Heat butter in a saucepan over medium heat until melted. Add garlic and cook until fragrant, about 30 seconds
Add in the cream and when just simmering add the Parmesan cheese in batches, stirring frequently until each batch is melted. Continue stirring until sauce is thickened and coats spoon.
Add parsley and salt and pepper to taste then toss with pasta and serve.
Notes
Do NOT use store bought grated or pre-shredded Parmesan cheese. It will not melt properly for this sauce. Use a chunk of high quality Parmesan like Parmigiano-Reggiano.
