Step 1

In a large non-stick skillet, melt butter over medium heat. When hot, add garlic and cook for 30 seconds or until fragrant, stirring constantly. Make sure not to burn the garlic.

Step 2

Stir in flour and cook for 1 minute or until lightly golden, stirring constantly. You want to cook it just long enough so it doesn’t taste like raw flour.

Step 3

Gradually whisk in half and half. Season with salt and pepper. Simmer until thickened, about 1-2 minutes, stirring occasionally. If any lumps form, just whisk them out. Simmer time will depend on multiple factors, one of them being the size of your pan. You basically want the sauce to cook just until thickened. Properly thickened sauce should coat the back of your spoon.

Step 4

Stir in Parmesan cheese and parsley. Remove pan from heat. Sauce is best when served immediately. It will thicken upon standing. See notes on serving suggestions.
