This is one of the best recipes to make your own version of Olive Garden's famous Alfredo sauce. This recipe is for a large dinner party. Please feel free to scale the recipe down for a small family.
Note: Make sure you whisk in the flour early while you are melting the butter with the garlic to avoid a "floury" flavor. The flour is important to avoid a thin sauce.
This sauce is very versatile. Add grilled marinated chicken for a great Chicken Alfredo. Add sautéed shrimp and scallops with Old Bay Seasoning, white wine, shrimp stock, and chopped green onions for Seafood Alfredo.
Extra sauce can be frozen for later use.
