With a pizza stone in the oven, preheat oven to 400℉.
Whisk together the olive oil, garlic, Parmesan cheese and salt.
On a lightly floured surface, roll out the dough so that it’s about ⅛ “ thick.
Sprinkle pizza peel with semolina or cornmeal (to help the dough slide off the peel and onto the pizza stone).
Place dough on pizza peel. Using your fingers or a pastry brush, spread the olive oil mixture on the dough.
Sprinkle dough with mozzarella cheese.
Evenly spoon dollops of ricotta across the pie.
Sprinkle pizza with oregano.
Transfer the pizza to the pizza stone. Bake for 12-15 minutes or until the cheese is lightly browned on top. Serve with a sprinkling of crushed red pepper flakes.
(Alternatively, you can bake this without a pizza stone and pizza peel using a ¼ sheet pan.)
