Preheat your oven to 475°F (245°C). Place a cast iron pizza pan in the oven to preheat as well.
Roll out the pizza dough on a lightly floured surface to your desired thickness. Carefully transfer the dough to a piece of parchment paper (paper sides are just a bit wider than the cast iron pizza pan) and place on a cutting board/pizza peel.
Then, begin to assemble your pizza directly on top of the parchment paper. Brush the dough evenly with olive oil and sprinkle Italian seasoning over the top, leaving a small border around the edges.
Place the mozzarella slices on top of the seasoned olive oil.
Arrange the thinly sliced Campari tomatoes and pepperoni slices on top of the cheese.
Dollop spoonfuls of ricotta cheese evenly over the pizza.
Season with salt and pepper to taste.
Once preheated, remove the preheated cast iron pizza pan from the oven and next, carefully transfer the pizza (parchment paper and all) onto your preheated pizza stone. Carefully transfer the pizza back into the preheated oven.
Bake for 8 minutes, and then carefully remove the parchment paper, pulling it on one side as you lift up the crust with a spatula. Rotate the pizza and continue to cook for another 10 minutes, or until the crust is golden brown and the cheese is bubbly.
Remove the pizza from the oven and let it cool for a few minutes before slicing.
Garnish with fresh basil leaves.
