Do you have a top broiler? I have one in my oven and turn it on when making the pizza. I’ve been making NY style pizzas with home oven temps and have not had the toppings lag behind with a steel, which is on the top rack. They take around 5 minutes to bake. My oven goes to 550 and I preheat it for at least an hour.
