I got this pizza from a food company today called Schwan Foods, and directions said to preheat the oven and pan that you are going to cook the pizza on too. I've never cooked a pizza where it says preheat with the pan in the oven. The other frozen pizzas I have cooked in the past say to preheat the oven, but don't tell you to preheat the oven with the pan inside the oven. I was just wondering what is the difference between the frozen pizza I got today that says preheat with pan in the oven instead of just preheating the oven like the frozen pizzas I normally cook? I ended up cooking the pizza on the rack for crispier crust because I didn't trust a pan being inside my oven while I was preheating. Any information will be helpful.
