Preheat your oven to 425°F (220°C). This high temperature will ensure your pizza crust gets that perfect crispy finish.
In a medium saucepan over medium heat, melt 1 tablespoon of butter. Add the roasted and minced garlic to the melted butter, stirring for about a minute until fragrant.
Sprinkle in 2 tablespoons of all-purpose flour while continuously whisking to form a roux. Cook for another minute until it’s slightly golden.
Gradually whisk in 1/2 cup of skim or 1% milk and 1/4 cup of half & half. Keep whisking until the mixture is smooth and starts to thicken.
Remove the saucepan from the heat and stir in 1/4 cup of fresh grated parmesan cheese. Season with ground black pepper, dried thyme, dried oregano, and garlic salt. Mix until well combined.
On a baking sheet or pizza stone, roll out the refrigerated Pillsbury Classic Pizza Crust according to package instructions. Pinch the edges to form a crust.
Spread the creamy garlic white sauce evenly over the prepared pizza crust. Layer the chopped chicken breasts on top, followed by the chopped red onions. Sprinkle 3/4 cup of shredded mozzarella cheese over everything.
Place your assembled pizza in the preheated oven. Bake for 12-15 minutes or until the cheese is bubbly and the crust is golden brown.
Once done, remove the pizza from the oven and let it cool for a few minutes before slicing. Serve hot and enjoy the delightful flavors of your homemade Roasted Garlic Chicken White Sauce Pizza!
