Frequently Asked Questions (FAQ) of Homemade Alfredo Sauce

Can I use milk instead of heavy cream?

• You can, but the sauce will be thinner. If you use whole milk, add an extra tablespoon of butter or a teaspoon of flour to help thicken, and cook a bit longer.

How do I reheat Alfredo sauce without it separating?

• Warm slowly over low heat while stirring. Add a splash of cream, milk, or reserved pasta water and whisk until smooth.

Can I use pre-grated Parmesan?

• Pre-grated cheese often has anti-caking agents that prevent smooth melting. Freshly grated Parmesan gives the best creamy texture.
