Whether you have a frozen pizza, refrigerated pizza slices, or cold pizza from who knows where, reheating your pizza properly makes a huge difference to the taste and texture. Use a thick skillet to create a crunchy crust.
Place your pizza on the pan. Heat the pan on medium heat.
When the pizza crust has softened and is beginning to get crispy, flip over the pizza. Depending on how slow your burner is to heat up and how thick your pan is, it might take 3-5 minutes to get to this point (maybe longer if you have multiple slices and they're frozen). I notice the pizza is ready to flip when the pan begins to get oily. It's oily because the fat is melting off the crust as the pizza heats up.
Allow the pizza toppings to heat up in the hot pan. If you're using a thick pan, turn off the heat as the residual heat will continue warming up the cheese (and we want to avoid the risk of burning your pizza). If you're using a thinner pan or an induction cooktop, heat for 1-2 minutes. The pizza is ready when you see the cheese softens and begins to melt. You can see it in the photo where the cheese begins to ooze.
Remove from the heat. Cut your pizza into thin strips if desired. Enjoy your reheated pizza!
Notes
Alex loves cutting his reheated pizza into thin strips with a pair of scissors. He thinks it makes the pizza, which tastes like fried bread, easier to eat. Strangely, he doesn't cut fresh homemade pizza into narrow strips, only the reheated leftovers.You can eat the pizza slice however you like it—whole or trimmed down.
