Bring the pizza dough to room temperature for 1 hour before shaping.
Place a pizza stone or steel in the oven and preheat to 500°F for at least 45 minutes.
On a floured surface, divide the dough in half and stretch each into a 10 to 12 inch round. Transfer to a floured pizza peel.
In a bowl, mix the ricotta, garlic, Italian seasoning, salt, and black pepper.
Brush each dough round lightly with olive oil. Spread half the ricotta mixture over each, leaving a 1/2 inch border.
Top with mozzarella and Parmesan. Sprinkle with red pepper flakes if using.
Slide onto the hot stone and bake 10 to 12 minutes, until the crust is golden and the cheese is bubbly with browned spots.
Let cool 2 minutes, then top with fresh basil, slice, and serve.
