You can cook your chicken and garlic in the oven at the same time. Spray a baking sheet with cooking spray. Cut your chicken breasts in half, place on the baking sheet and sprinkle with garlic salt. Rip off a large sheet of foil and fold into a square box so that it is raised off of the baking sheet enough that any chicken juices will not reach your garlic. Place garlic on the foil and bake at 375° until the chicken juices run clear and the internal temperature reaches 165°.
Remove from the oven and chop the chicken into small bite sized strips. Peel the garlic and mince.
For the Pizza Crust
Pre-heat oven to 400°. Spray your pizza baking sheet with cooking spray. Spread the pillsbury pizza dough out to the desired thickness and cook for about 5 minutes. Remove from the oven.
While the pizza dough is in the oven, add butter and roasted garlic to a medium sauce pan. Cook for about 2 minutes over medium heat. Stir in your milk and half & half and whisk together. Reduce heat to medium-low. Sift flour over milk mixture while whisking together to prevent lumps. Add ground black pepper, ground thyme, dried oregano, 1/2 teaspoon dried parsley & garlic salt and whisk well. Turn off heat and add parmesan cheese. Stir together until all cheese is melted.
Spoon your sauce onto half baked pizza crust.
Top with chicken
Sprinkle mozzarella cheese evenly over entire pizza
Sprinkle red onion evenly over mozzarella cheese
Sprinkle 1 teaspoon (or more) dried parsley on the very top of the pizza
Final Baking Instructions
Place entire pizza back in the oven for an additional 5-6 minutes. Turn on the broiler and broil for 1-3 minutes, or until the cheese and crust reach your desired doneness!
