The best way to reheat pizza in an air fryer is at 325°F for 3–4 minutes — that's it. No preheating drama, no soggy microwave disasters, and no waiting 15 minutes for your full-size oven to warm up for a single slice. The air fryer circulates hot air around your pizza, crisping the crust while melting the cheese back to its original gooey glory. If you've been settling for rubbery leftover pizza, you're about to change your entire cooking routine.
Leftover pizza is one of those foods that can either taste amazing or completely disappointing, depending on how you warm it up. Most people default to the microwave because it's fast, but speed comes at a cost — you end up with a floppy, chewy mess. The air fryer hits the sweet spot between convenience and quality, giving you results that rival a fresh slice in a fraction of the time a conventional oven takes.
Whether you're reheating a classic margherita, a loaded meat-lover's pie, or even those air fryer mac and cheese balls you made last night, the technique is surprisingly simple once you know the basics. Let's break down everything you need to know.

You might think the method you use to reheat a couple of slices doesn't matter financially. But when you add up the energy use over weeks and months, the differences become noticeable — especially if you're already mindful about your kitchen budget.
Here's how the three main reheating methods stack up for two slices of pizza:
| Method | Temperature | Time | Avg. Wattage | Est. Energy Cost | Crust Quality |
|---|---|---|---|---|---|
| Air Fryer | 325°F | 3–4 min | 1,500W | ~$0.01 | Crispy |
| Conventional Oven | 375°F | 10–12 min (+ preheat) | 2,500W | ~$0.06 | Crispy |
| Microwave | N/A | 30–60 sec | 1,000W | ~$0.002 | Soggy |
| Skillet (stovetop) | Medium heat | 5–7 min | 1,200W | ~$0.02 | Very crispy bottom |
The microwave wins on pure cost, but you're paying for it in texture. The oven delivers good results but uses roughly six times more energy than the air fryer for the same outcome. The air fryer lands right in the middle — minimal energy use with maximum quality.
Beyond the electricity bill, there's the time factor. Your conventional oven needs 10–15 minutes just to preheat. That's wasted energy heating a large cavity for two slices of pizza. The air fryer's compact chamber heats almost instantly, which means:
Pro tip: If you reheat pizza even twice a week, switching from oven to air fryer can save you $5–8 per year in energy costs alone — small individually, but it adds up across all your air fryer cooking.
There's a lot of bad advice floating around about reheating pizza. Some of it sounds logical but doesn't hold up once you actually test it. Let's clear a few things up.
This is the most common myth, and it's understandable. The microwave is fast and convenient. But microwaves work by exciting water molecules, which turns your crispy crust into a chewy, rubbery base. The cheese melts unevenly, and any toppings with moisture (like vegetables or fresh tomato) turn into a soggy puddle.
Some people suggest placing a cup of water in the microwave alongside the pizza to absorb excess moisture. According to the USDA's guidelines on reheating leftovers, the key is reaching an internal temperature of 165°F — but that doesn't address texture at all. The water trick helps slightly, but it still can't match what circulating dry heat does for a crust.
Many recipes insist on preheating your air fryer for 3–5 minutes before adding the pizza. For most basket-style air fryers, this is unnecessary when reheating pizza. The food is thin enough that it starts cooking almost immediately. Skipping the preheat saves time and energy without any noticeable difference in the final product.
That said, if you're using an air fryer oven (the toaster-oven style), a quick 2-minute preheat can help since the cavity is larger. It's not a hard rule — just something to experiment with based on your specific model.
Warning: Don't stack slices on top of each other in the air fryer. Overlapping blocks airflow and creates steamy pockets that make the pizza soggy — the exact thing you're trying to avoid.
The technique varies slightly depending on what kind of pizza you're working with. Here's how to handle each type for the best results.
Thin crust is the easiest to reheat because it crisps quickly. Just watch it closely — an extra minute can turn crispy into burnt.
Thick crust and deep dish styles need a slightly different approach. The dense dough requires more time to heat through without burning the top.
Deep dish pizzas like those from a cast iron or Dutch oven recipe hold a lot of moisture in the thick dough, so the lower temperature prevents the outside from overcooking while the inside catches up.
If you froze your leftover pizza (smart move for meal prep), don't thaw it first. Go straight from freezer to air fryer:
Going from frozen actually works well because the air fryer defrosts and crisps simultaneously. Thawing first creates excess moisture that works against you.
You don't need much beyond the air fryer itself, but a few inexpensive accessories can improve your results and make cleanup easier.
Quick tip: Cut a piece of parchment paper slightly smaller than your basket — if it covers the edges, it blocks airflow and defeats the purpose of using an air fryer in the first place.
Not all air fryers handle pizza equally well. Here's what to consider:
If you're shopping for an air fryer primarily for reheating, look for a model with at least a 4-quart capacity. Anything smaller and you'll struggle to fit a standard pizza slice without it touching the heating element.
For most pizza styles, 325°F works best. Thick crust or deep dish benefits from a slightly lower 300°F to ensure the center heats through without burning the top. Frozen slices do well at 350°F since they need the extra heat to defrost and crisp simultaneously.
Thin crust takes about 3–4 minutes. Thick crust and deep dish need 4–5 minutes. Frozen slices require 5–6 minutes. Always check a minute early — air fryer models vary in power, and overcooked pizza goes from crispy to charred quickly.
In most cases, no. Basket-style air fryers heat up fast enough that preheating is unnecessary for thin items like pizza. If you're using a larger air fryer oven, a quick 2-minute preheat can help even out the heat distribution.
You can reheat 2–3 slices at a time as long as they don't overlap. Overlapping blocks the hot air circulation and creates steamy spots that make the crust soggy. If you need to do more, reheat in batches.
Perforated parchment paper is the best option — it prevents cheese from dripping through the basket while still allowing airflow. Foil works in a pinch but can block airflow if it covers too much of the basket. Never use wax paper, as it's not heat-safe.
The most common reasons are stacking slices, using too low a temperature, or not leaving enough space around the pizza for air to circulate. Make sure slices sit in a single layer with at least a half-inch gap from the basket walls.
It's remarkably close. The circulating hot air mimics the effect of a pizza oven by crisping the crust from all sides. The cheese melts evenly and the toppings stay intact. Most people find air fryer reheated pizza better than delivery pizza that's sat in the box for 30 minutes.
