Tips for Perfect Alfredo Sauce

Use Freshly Grated Parmesan

Pre-shredded cheese contains anti-caking agents that prevent smooth melting.

Keep the Heat Gentle

Boiling cream or cheese causes separation or greasiness.

Add Cheese Slowly

Dumping it all in at once can cause clumps.

Use Heavy Cream Only

Half-and-half curdles and milk won’t thicken properly.

Reserve Pasta Water

A splash helps emulsify the sauce for perfect cling.

Variations

Garlic Lover’s Alfredo

Double the garlic and add roasted garlic cloves.

Chicken Alfredo Sauce

Add cooked sliced chicken and simmer gently.

Shrimp Alfredo

Sauté shrimp in butter and add to sauce at the end.
