Set the oven rack to the lower position. Preheat to 500ºF (260ºC). Lightly brush a large baking sheet with olive oil. Evenly sprinkle cornmeal on the pan if desired.
On a lightly floured surface, stretch and shape the 1 pound fresh pizza dough, into a 10-inch circle.
Transfer the dough to the prepared baking sheet. Use your fingers to press the dough into a 12-inch circle. Leave the edges slightly thicker, about ½-inch tall and wide.
Brush some olive oil on the edges of the dough to make the crust crispier when baked.
Spread the ½ cup pizza or marinara sauce on top, followed by the 1 cup shredded mozzarella cheese and ¾ cup thinly sliced zucchini,. Sprinkle the ¼ teaspoon Italian seasonings, kosher salt, and black pepper on top.
Bake the pizza for 10-12 minutes until the crust is golden brown and the cheese is melted and bubbly.
Sprinkle some red pepper flakes and grated parmesan cheese on top. Slice and serve the pizza immediately while it is still hot.
