FAQ
Is Alfredo sauce the same as béchamel sauce?
No. Béchamel is a white sauce made from a roux (butter and flour) and milk. Alfredo is a reduction sauce based on butter, cream, and cheese, with no flour.
Can I make a lighter version of Alfredo sauce?
Yes. Common lighter modifications include using half-and-half or evaporated milk instead of heavy cream, incorporating cream cheese or Greek yogurt for thickness, or blending steamed cauliflower or white beans into the sauce for creaminess with more fiber and protein.
Why does my homemade Alfredo sauce separate or become grainy?
This is often due to overheating or using pre-grated cheese with anti-caking agents. Use freshly grated Parmesan, melt it into the warm (not boiling) cream and butter mixture off the heat, and stir constantly until just combined.
