Frying pan with a lid. Put the pan on medium-high cover with lid. Let it heat up for a few minutes and then pop the pizza in. Wait a few minutes for the inside of the pan to reheat and then cut the heat down to medium low. Melty cheese and lightly toasted crust.
I keep baker’s parchment handy and use the regular toaster. Tear off a strip of parchment the width of the toaster slot, fold in half, slip the pizza into the crease and pop it in the toaster (crease side down of course). Crisp crust, melty cheese and no cleanup!
If it’s refrigerated but not frozen, I usually put it in the oven at 425 degrees for about 12 minutes (any less and it’s not warm enough).
If it’s frozen, 450 degrees for 15 minutes usually does it.
If it’s not warm enough after baking, 30 seconds in the microwave.
Not’s the only way to have that stuff.
I’ve done most of the above; cast iron pan, m/w, toaster over. The toaster oven works best for me. Mine has convection and a ‘frozen pizza’ setting. Perfect every time.
Is this true? I throw used aluminum fold in the recycling all the time. Half the stuff I throw in there has food on it or in it. 
Doesn’t the cheese slip off? Otherwise this is an awesome idea.
I advocate the pan method, with a generous dollop of olive oil.
You’d have to check with your recycling authority, but everywhere I’ve ever lived, recyclable materials that have been in contact with food cannot be recycled unless they’ve been cleaned. So milk jugs and the like have to be, at the least, rinsed out, but that cardboard pizza box is simply ineligible because you’re not going to get that grease out of the cardboard.
Must vary by recycling co. Our’s will take pretty much anything in any condition. Greasy pizza boxes are certainly no exception. <shrug>
I do rinse stuff out, but I don’t scrub. I just looked at the city’s recycling website and it doesn’t mention anything like “no greasy pizza boxes” though they do say to rinse cans.
Huh. And mine is very explicit:
“No garbage
No food waste
No food tainted items (used paper plates, paper towels, or paper napkins)
No pizza boxes
No egg cartons
No wax-coated cartons
No ice-cream cartons
No aluminum foil
No styrofoam (like cups/plates & packaging)
No aerosol cans, propane tanks or helium tanks
No batteries”
What I do is this: cut the pizza all the way around, about 1/3 the way from the crust to the center. Eat the outer (crust) pieces first. Next morning, heat and eat the inner pieces. Since we’re talking Pizza Hut, it doesn’t matter how the center is reheated, or if it’s left cold.
From frozen, I do 350 for 15-20 minutes depending on thickness of the slices.
Me too. The SO thinks it’s disgusting. Weird, eh? I mean, who ever heard of hot pizza for breakfast? If you want a hot meal, pull the Panang curry out of the fridge!
She likes to use the perforated pizza pan to reheat pizza in the oven.
And they wonder why people just chuck everything in the trash.
