Prepare the Fathead-Style Pizza Dough according to recipe directions. Shape into a pizza crust and bake as directed until lightly golden. Set aside while preparing the chicken, sauce, and toppings. Keep the oven set to 425°F.
Cook The Chicken:
Heat a skillet over medium-high heat. Add a little olive oil or butter if desired. Add the sliced chicken breast, sprinkle with Italian seasoning, and cook until golden brown and no longer pink in the center, 5–7 minutes depending on thickness. Transfer to a plate and set aside.
Make The Alfredo Sauce:
In a medium skillet or saucepan, melt the butter and cream cheese over medium-low heat, whisking until smooth.
Slowly whisk in the heavy cream. Add garlic powder, parsley, basil, salt, and pepper.
Once the cream mixture is hot (but not boiling), stir in the Parmesan cheese and the 1/2 cup mozzarella. Continue whisking until the sauce is smooth, slightly bubbly, and thickened enough to coat a spoon, 3–5 minutes. Remove from heat.
Assemble And Bake The Pizza:
Spread about 1 cup of the Alfredo sauce evenly over the pre-baked pizza crust. Save any extra sauce to serve for dipping or use in another recipe. Arrange the cooked chicken slices on top, then sprinkle with the remaining 1 cup shredded mozzarella cheese.
Return the pizza to the 425°F oven and bake until the cheese on top is melted and bubbly, about 8–10 minutes. For extra color and texture, place under the broiler for 1–2 minutes, but watch closely to avoid burning.
Remove from the oven, let cool 2-3 minutes before slicing, and serve warm.
