While some people may love cold, leftover pizza, if you want to enjoy your leftover slice the way it was when you made it or it was delivered, you have to heat it up again. Although reheating sounds simple enough, you can’t just throw a slice in the microwave and push start. Without the proper reheating technique, your pizza will come out tough, overly chewy and inedible. Aside from the microwave, you can reheat pizza in the oven, the stove and even your outdoor grill, as long as you follow a few simple tips.


Conventional Oven

Heating the pizza in the oven is one of the most common ways to effectively reheat pizza. In an oven preheated to 400 degrees Fahrenheit, place the pizza on a baking sheet lined with parchment paper. Parchment paper prevents the pizza from sticking to the pan and also helps to keep the crust crispy. The pizza only needs to be in the oven for about six minutes, or until fully heated. Aside from parchment paper, the pizza can also be reheated in the oven on heavy-duty aluminum foil. Double the foil for extra sturdiness.


Microwave and Toaster Oven

Heating pizza in the microwave can turn out disastrous if its not done right. For best results, a combination of time spent in the microwave and a toaster oven will bring the pizza close to how it looked and tasted when you first bought or made it. Only place the pizza in the microwave for no more than 20 seconds, or just long enough to reheat the slice. Brushing the crust with melted butter will help keep it soft, preventing it from hardening in the microwave. After the quick heating, place the pizza in a toaster oven heated to 350 degrees Fahrenheit for five to 10 minutes. The toaster oven will crisp the crust and finish heating the slice.


Stove Top

When heated in a covered pan on the stove, leftover pizza is slowly steamed back to life. For best results, only add enough slices to the pan for a comfortable fit to ensure that the heat distributes evenly. Use a non-stick pan, and don’t bother adding oil or cooking spray. Heat the pizza in the pan over medium-high heat on the stove for about 30 minutes. This allows for only a minimal amount of water loss in the crust. The steam generated from the pan being covered helps to soften and reheat the cheese and other toppings.


Grill

Grills can do more than just cook burgers and other barbecue-related items; you can also use your outdoor or indoor grill to reheat pizza. Simply wrap the leftover slice in foil and place it on the preheated grill. The foil will help keep the moisture in the pizza. Once the slice is fully heated, remove the foil and place the slice directly on the grill to crisp the bottom crust. Brushing the crust with olive oil infuses additional flavor in the crust as well as helping to keep the it moist. The pizza should be placed on the grill away from direct heat to avoid burning the bottom of the pizza.
