This creamy white pizza sauce is made with sharp parmesan cheese and rich half and half. It is so smooth and bursting with cheesy creamy flavors, and perfect on top of pizza, over bread, or for dipping your breadsticks in.
Heat the butter in a small saucepan over medium heat; stir in the garlic. Cook for 30 seconds until fragrant.
Whisk in the flour and stir to make a roux.
Add the milk, onion powder, salt, pepper, and Parmesan cheese.
Cook and whisk continuously for about 5 minutes until the cheese is melted and the sauce has thickened slightly. Add more milk if the sauce is too thick.
Remove from heat and enjoy on pizza or as a dipping sauce for breadsticks.
