Place a rack in top-most position of the oven; preheat to 475°F. Place dough on a work surface and stretch out to a 10" round and cover loosely with plastic wrap, while preparing the toppings.

Drizzle 1 tablespoon oil on a well seasoned cast-iron skillet. Carefully lay dough inside the skillet and use your fingers to help extend dough all the way to the edges. Season with salt and crushed red pepper, and drizzle remaining olive oil on top.

Place the cast iron skillet in the preheated oven until the crust is lightly golden brown, about 5 minutes.

Remove skillet from the oven, spread marinara over the entire dough surface. Top with mozzarella cheese, tomatoes and Italian seasoning. Return the skillet to the oven and bake on the top rack until the crust is deeply golden brown around the edges and the cheese is bubbly, about 10 minutes. Let cool for 5 minutes, then garnish with basil and serve.
