The Top 3 Ways to Reheat Pizza (Backed by Science)

If you’re like most people, you have a love-hate relationship with leftover pizza. It’s one of the most difficult (and controversial) foods to reheat, yet you keep coming back to it again and again.

Sure, there’s no shame in eating leftover pizza straight from the fridge. But the thought of a cold slice pales in comparison to the freshly baked goodness that it was just hours ago—so you make the executive decision to reheat.

But before you pop your leftover pizza in the microwave, take a look at these three science-backed methods to reheat your pie and still retain its crispy, cheesy, melty glory. Some might surprise you, but rest assured we tested them for quality assurance.

Honorable Mention: Fire Up the Grill

One of the biggest knocks against reheating pizza in the microwave is that the crust turns out too chewy. The grill mitigates this by putting the pizza in direct contact with heat, making the crust crispy while the indirect heat makes the toppings melty.


  • Set the grill to medium-high heat
  • Put the pizza straight on the grate and leave the grill open
  • Cook for six minutes, or until the the bottom crust is crispy enough for you

Second Best: Rebake In the Oven (the Right Way)

Since pizza is originally baked, people assume putting it in a piping hot oven is the best way to reheat it. That’s partially true, but there’s an important twist you need to consider.

When you store pizza crust, the starch molecules undergo retrogradation, which is a fancy way of saying it gets stiff and dry. You can reverse this effect by reheating the pizza to 140 degrees, but here’s the catch: you need to let the pizza crust reheat gradually. This gives it enough time to release moisture without getting rubbery.


  • Put the cold pizza on a baking sheet and cover it with aluminum foil
  • Place it on the lowest rack of a cold oven (no preheating!)
  • Set the oven to 275 degrees and cook for 25-30 minutes

The Winning Warmup: Use a Skillet on the Stovetop

Forget food blogs and cookbooks—the best way to reheat pizza was born in no place other than the /r/pizza subreddit. That may seem juvenile, but the process is actually genius.

It combines direct heat for a crispy crust with steam to evenly melt your cheese and toppings. It’s as close to a fresh slice of pie as you can get. Just be sure to use a non-stick skillet rather than a cast-iron skillet (which heats up way too fast).


  • Preheat the skillet for a couple of minutes on medium-high heat
  • Put the pizza in the skillet and cook for two minutes
  • Pour two drops of water in the skillet as far from the pizza as possible
  • Cover the skillet with a lid and turn the heat to low
  • Cook for another minute
