White pizza always refers to the absence of tomato sauce, but it may mean either a pizza with no sauce and white cheese, or one in which a white sauce replaces the tomato sauce. White pizza sauce begins with a basic white sauce made from butter, flour and milk or heavy cream, to which Parmesan cheese, garlic or other seasonings added. A classic Alfredo sauce may also be used as a tasty white sauce for pizza.
Parmesan Pizza Sauce
Chop the onion into small pieces and mince the garlic.
Melt 1 tbsp. of butter in a saucepan over medium heat, being careful not to burn it. Add the onion and garlic to the pan and cook until the onion is tender but not brown.
Stir flour and pepper into the onion mixture.
Add the milk and chicken bouillon granules all at once. Cook and stir until slightly thickened and bubbly.
Mix in 1/4 cup of Parmesan cheese, stirring until it melts and the sauce is smooth.
Classic Alfredo Sauce
Melt 1/4 lb. of butter in a saucepan over low heat.
Remove pan from heat and add 1 cup heavy cream, 3/4 cup of Parmesan cheese and salt and pepper to taste.
Put the pan back over low heat and stir until the sauce is smooth, being careful not to let it come to a boil.
