Melt the butter in a saucepan over medium heat.
Add garlic and cook for 30 seconds, until fragrant.
Whisk in the flour, pepper, and salt. Cook for 1 minute while whisking.
Slowly add the milk, whisking until well combined. Continue whisking constantly until the sauce thickens, about 1-2 minutes. It should be thick enough to coat the back of a spoon.
Whisk in the parmesan and parsley and remove from heat.
Thin with pasta water if needed.
White garlic sauce is best served right away. Serve with pasta, beef, chicken wings, and more!
