Place an 8-inch cast iron skillet in the oven and preheat to 450 degrees F.

While the skillet is preheating, using a rolling pin, carefully roll out the pizza dough into an 8 to 10 inch circle.

Remove the skillet from the oven.

Using a pastry brush, brush the olive oil all over the cast iron pan.

Gently fit the pizza dough inside the cast iron pan making sure it goes all the way to the edges

Spread the pizza or marinara sauce over the dough.

Top with the shredded mozzarella cheese followed by the sliced pepperoni.

Return the pan back to the oven and continue baking for an additional 10 to 12 minutes or until the pizza is golden brown and the cheese is bubbly.
