PIZZA BIANCA (WHITE PIZZA)
1 loaf frozen whole wheat bread dough, thawed Or any bread dough recipe 2 1/2 tbsp. olive oil 2 tbsp. cornstarch 2 c. milk 1 tsp. salt 1 tsp. pepper 3 cloves garlic, minced 1 tbsp. white wine, optional 1 tsp. onion powder 1 tsp. oregano 2 tbsp. Parmesan cheese 1 c. shredded mozzarella 1 c. shredded provolone
Roll bread dough on lightly floured surface to fit pizza pan or baking sheet. Place on oiled pan. Pinch edges of dough into 1/2 inch rim all the way around pizza.
In medium saucepan saute garlic until soft. Blend in cornstarch, salt, pepper and spices. Gradually add milk, wine and Parmesan cheese. Heat to boiling, stirring constantly, cook approximately 2 minutes. Let white sauce cool slightly.
Brush dough surface with small amount of olive oil. Then spread white sauce over crust. Sprinkle mozzarella and Provolone over sauce. Bake at 425 degrees for 20 minutes or until hot and bubbly.
it really depends on what other toppings you ar using. you can use an alfredo type sauce in place of the white sauce, or you can add some ricotta.... I think if you just used a little oil it would come out too dry.
My husband brought me a slice from Bertucci's the otherday, it had chicken and broccoli. I didn't detect the white sauce, it must've just blended in with the cheese nicely.
