Heat the oven to 475 degrees and place a baking sheet or pizza stone inside to warm.
Roll the dough into a 12-inch circle on parchment paper. Use your fingers to pinch and shape the outer edge into four to six raised, bone-like segments.
Stir the olive oil and minced garlic together in a small bowl. Brush this mixture over the entire surface, paying extra attention to the shaped edges.
Press the grated Parmesan firmly into the oiled edges so it sticks and forms the crust. Spread the ricotta evenly across the center, then scatter the mozzarella on top.
Sprinkle the oregano and salt over the cheeses. Slide the pizza, still on the parchment, onto the hot baking sheet.
Bake for 12 to 15 minutes until the crust is deep golden and the cheese bubbles. Remove from the oven and let it rest two minutes before scattering parsley leaves over the top.
