Preheat the oven to 425°F. Take out a sheet pan and set it aside.
Place a piece of parchment paper on a cutting board or work surface. Add the puff pastry dough sheet on top.
Use a rolling pin to roll out puff pastry dough so it is 2 to 3 inches larger.
Assemble the puff pastry pizza by adding a layer of pizza sauce in the center, leaving 1 inch around the outside without sauce for the crust.
Add tomato slices on top of the sauce.
Then, top it with shredded and fresh mozzarella cheese.
Add the puff pastry pizza to the oven and bake for 10 to 15 minutes or until the cheese has melted and the crust is fluffy and golden brown.
Remove the puff pastry pizza from the oven and top it with fresh basil before serving.
