1. Preheat the oven to 200 degrees Celsius. Before putting the pizza in the oven, be sure to preheat the oven to the right temperature. This method is especially effective if you are reheating the entire pizza. Otherwise, if you put it in the oven too early, the heated pizza will go soft in places it shouldn't. Only when done properly can the original flavor of pizza be preserved.
2. Place the pizza on the baking sheet and insert it into the oven. If you have a ceramic griddle, that's even better because the construction of ceramic allows the food to heat evenly. If you don't have one, a roasting pan or baking dish will also work.
3. Heat for 15 minutes. During this period, you should always observe the situation in the oven. When the cheese starts to bubble and brown spots appear, the pizza is considered to be hot. Then you can take the pizza out of the oven and start enjoying it.
