Alfredo sauce is a creamy white sauce that is typically made with butter, heavy cream, Parmesan cheese, and garlic. The sauce is believed to have originated in Rome, Italy, and was created by restaurateur Alfredo di Lelio in the early 20th century. The sauce is known for its rich, velvety texture and decadent flavor.
To make Alfredo sauce, butter is melted in a pan, and minced garlic is sautéed until fragrant. Heavy cream is then added, and the mixture is brought to a simmer. Grated Parmesan cheese is stirred in until melted and the sauce is thickened. Salt and pepper are added to taste, and the sauce is then typically served over pasta.
Alfredo sauce can also be enhanced with additional ingredients, such as chicken, shrimp, or vegetables, to create a more complex dish. While the sauce is undoubtedly rich and delicious, it is also quite high in fat and calories, so it should be enjoyed in moderation as part of a balanced diet.
