Reheating pizza in an air fryer is pretty simple, but there are a lot of small things that can change the result. The thickness of the crust, amount of toppings, starting temperature, air fryer model, and whether you use a liner can all make a difference. This guide covers the basic method, timing, different pizza styles, frozen leftovers, troubleshooting, storage, and food safety.

▮The basic method

For most refrigerated pizza, 350°F / 175°C for 3-5 minutes is a good starting point. Put the pizza directly in the basket in a single layer with the toppings facing up. Start checking around 3 minutes and add 30-60 seconds if needed. There's normally no reason to flip the slice.

You can put the pizza straight from the refrigerator into the air fryer. Preheating isn't essential, but if you normally preheat your air fryer, remember that the pizza may cook a little faster. Air fryers also vary considerably, so the times below are starting points rather than exact instructions.

The goal is simple: hot center, melted cheese, crispy bottom and a crust that isn't dried out.

▮Temperature and time guide

Pizza type	Temperature	Starting time
Thin crust	350-375°F / 175-190°C	2-4 min
Regular crust	350°F / 175°C	3-5 min
New York style	350-375°F / 175-190°C	3-4 min
Thick crust	325-350°F / 165-175°C	4-6 min
Stuffed crust	325-350°F / 165-175°C	4-7 min
Deep dish	325-350°F / 165-175°C	5-8 min
Heavily topped pizza	325-350°F / 165-175°C	4-7 min
Frozen leftover slice	350°F / 175°C	6-10 min

Thin crust needs less time because it heats quickly and can become hard if overcooked. Thick crust, stuffed crust and deep dish need more time for the center to heat through, so a slightly lower temperature is usually more useful than simply turning the heat up. Heavily topped slices can also take longer because there is more food to heat.

▮Getting the best crust

For the crispiest result, put the pizza directly on the basket or rack when your air fryer allows it. Keep slices in a single layer and leave some space between them so air can circulate. You generally don't need to add oil because pizza already contains plenty of fat from the cheese and toppings.

Parchment and silicone liners are useful for cleanup, but they can change how the bottom cooks. A perforated air-fryer parchment liner allows more airflow than a solid liner. If maximum crispiness is the goal, the bare basket will usually give you better contact and airflow. Never put loose parchment into an empty or running air fryer because it can lift toward the heating element.

Foil can also be used only when permitted by your air fryer's instructions. Don't cover the basket in a way that blocks airflow, and don't use loose foil that can move around.

You also don't need to flip pizza. The toppings should stay facing up, and flipping can cause melted cheese and toppings to stick to the basket.

▮Adjusting for different pizza

The type of pizza matters more than trying to find one perfect cooking time. Thin crust and New York-style slices can be ready in only a few minutes, while deep dish and thick slices need more time at a lower temperature. Stuffed crust behaves similarly because there is more food inside the crust.

Pizza with lots of cheese, meat or vegetables may need additional time. Fresh herbs and delicate vegetables can dry out quickly, so adding things like fresh basil after reheating can work better.

For pepperoni-heavy pizza, some grease will naturally render during reheating. If there's a lot of excess grease, you can blot some off before cooking. Don't put paper towels in the air fryer.

If your pizza is already very dry, use a lower temperature and check it frequently. The air fryer removes surface moisture, which is useful for crisping but can make an already-dry slice even harder.

▮Frozen leftover pizza

You can reheat leftover pizza directly from frozen. Start around 350°F / 175°C for 6-10 minutes, checking earlier for thin slices and allowing additional time for thicker ones.

Frozen leftover pizza is different from commercially frozen pizza. If you're cooking a pizza that was sold frozen, follow the package directions because the recommended time depends on the particular product.

If you plan to freeze leftover pizza, wrapping individual slices tightly and storing them in an airtight freezer bag or container makes reheating easier. USDA lists pizza at about 1-2 months in the freezer for best quality.

▮Troubleshooting

⯁ The crust is too hard: The pizza was probably cooked too long or too hot. Lower the temperature and start checking earlier.

⯁ The cheese is dry or rubbery: Try 325-350°F instead of using a very high temperature and avoid cooking longer than necessary.

⯁ The bottom isn't crispy: Give it another 30-60 seconds. Also check that the basket isn't overcrowded and that a solid liner isn't preventing good airflow.

⯁ The middle is cold but the crust is done: Use a lower temperature and give it more time. This is especially common with thick or deep-dish pizza.

⯁ The toppings are getting burnt: Lower the temperature rather than continuing at high heat.

⯁ The pizza is greasy: Some toppings, especially pepperoni, naturally release fat. Blot excess grease before reheating if necessary.

⯁ The pizza is sticking: A small amount of parchment can help with cleanup, but direct contact with the basket generally gives a crispier crust.

▮Air fryer vs other methods

The air fryer is best when you want a crispy crust without heating a full-size oven. The microwave is the fastest option but usually leaves the crust soft. The oven works well when you're reheating a lot of slices, although it takes longer to heat up. A skillet can produce a very crispy bottom and gives you more control, but requires more attention.

For one or two leftover slices, the air fryer is a convenient middle ground between speed and texture.

▮Storage and food safety

The quality of the reheating starts with how the pizza was stored. USDA recommends keeping leftovers refrigerated at 40°F / 4°C or below and using refrigerated pizza within about 3-4 days. Perishable food should generally not sit at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F / 32°C.

For leftovers containing meat or other potentially hazardous ingredients, USDA recommends reheating leftovers to 165°F / 74°C. A food thermometer is the most reliable way to check, particularly with thick pizza where the outside can feel hot before the center reaches the proper temperature.

Reheating won't make food safe if it was stored improperly or left out for too long.

▮Common mistakes

The most common mistakes are using too much heat, cooking for a fixed amount of time without checking, overcrowding the basket, and assuming every type of pizza needs the same treatment. Thin pizza can burn quickly, while thick pizza can remain cold in the middle even when the outside looks finished.

Another mistake is putting the pizza box or other cardboard packaging into the air fryer. Always remove the pizza from its packaging first.

▮The easiest method to remember

If you don't want to think about all the different variables, start with:

350°F / 175°C for 3 minutes.

Check the pizza.

If it needs more time, add 30-60 seconds until it's done.

That's really the main trick. Start moderate, check early, and adjust based on the thickness and condition of the pizza rather than blindly following one exact time.

I honestly didn't expect much from vegetables in the air fryer. Tried broccoli one day just to see how it would turn out, and the crispy edges were actually really good.

Now I make it pretty often.

What food surprised you the most when you first tried it in the air fryer?

For me, it was anchovies. I always thought they had that really strong fishy taste, but once I started using a small amount in sauces, I realized they mostly just add a ton of savory flavor.

Now I actually keep a jar around.

I keep seeing baking soda recommended for cleaning air fryer baskets, especially when there's baked-on grease. But I've started wondering if it's actually a good idea for the basket itself.

The problem isn't really that baking soda is some dangerous chemical. It's that it's mildly abrasive. If you make a paste and start scrubbing a non-stick basket with it, you're basically adding another abrasive to a surface you're supposed to treat pretty gently.

For normal cleaning, I usually don't see a reason to use it. Warm water, dish soap and a soft sponge are enough for most of the stuff left after cooking. If something is stuck on, I'd rather let the basket soak for a while than start attacking it with a rough scrubber.

This is also why I've stopped thinking of "stronger cleaner" as automatically meaning "better cleaner." An air fryer basket isn't a stainless steel pan where you can go at a stubborn spot with whatever you've got under the sink. Once that coating gets scratched or worn, cleaning it isn't really getting easier.

The other thing that gets confusing is the difference between baking soda being safe around food and using it as a cleaner on a particular appliance. Those aren't quite the same question. Baking soda itself isn't what worries me here. It's the possibility of using it aggressively on a non-stick surface that needs to be handled carefully.

If someone really wants to use baking soda for stubborn grease, I'd check the manufacturer's cleaning instructions first and avoid scrubbing hard. And I'd rinse everything thoroughly afterward.

Honestly, soaking the basket in warm soapy water has solved most of my cleaning problems anyway. Baking soda sounds like the obvious answer when you see a nasty greasy basket, but sometimes the least exciting method is the one that makes the most sense.

Has anyone actually had a manufacturer's instructions recommend baking soda for their air fryer basket? I'm curious because I see the advice everywhere, but I don't see it mentioned nearly as consistently in the cleaning instructions.

I put the pizza straight in the air fryer at 350°F for about 3–4 minutes. That's my usual starting point for a regular slice, and it gets the bottom crispy again without drying everything out.

I used to microwave leftover pizza because it was quick, but the crust always came out soft and the cheese got that weird rubbery texture. The oven worked better, but heating up the whole oven for one or two slices felt like way too much work.

The 350°F and 3–4 minutes isn't really a hard rule, though. Thin crust can be ready sooner, while thick crust or deep dish might need a little longer. I just check the middle before taking it out. If the toppings are already hot and the crust is getting dark but the center is still cold, I'll give it another short round rather than turning up the heat and drying everything out.

I also keep the slices in a single layer. I've definitely tried cramming a few extra pieces in because I wanted them all done at once, but they don't crisp up as well when the air can't move around them.

I usually put the pizza directly in the basket. If you're trying to crisp the bottom, covering the whole thing with foil or parchment kind of defeats the purpose. You want the air getting underneath the slice.

If the crust is already pretty dry, a few drops of water can help keep it from drying out more. A light mist of oil can help if you want it a little crispier too. I don't bother with either every time though.

And if the cheese starts bubbling or the toppings start getting pushed around, I take that as a sign that it's getting plenty of heat. No point in leaving it in there just because the timer hasn't gone off yet.

It's funny how long I thought leftover pizza just wasn't that good. Turns out I was mostly just reheating it badly.

I’m always surprised by how little you sometimes need to make something good.

For me, it’s potatoes. A couple potatoes, some oil, salt and whatever seasoning I have around, and I’ve got a pretty solid side without spending much.

I didn’t really think of the air fryer as a breakfast thing at first, but now I use it for stuff I used to make on the stove.

For me, it’s bacon. Less mess, no standing over a pan, and I can just let it cook while I make my coffee.

I’ve started keeping a couple sauces around because some air fryer foods are good on their own, but one good sauce takes them to another level.

For me, garlic mayo is hard to beat. I’ll put it on chicken, potatoes, veggies, pretty much anything that comes out crispy.

Some nights I want something decent to eat but absolutely do not feel like actually cooking.

Mine is usually chicken tenders and frozen fries. Throw both in, wait a bit, and dinner is basically handled.

I used to just throw everything in and start cooking. But with some foods, I swear preheating makes a pretty big difference.

For me, it’s frozen hash browns. They seem to crisp up way better when the basket is already hot.

What’s the one food where you actually bother preheating first?

I’ve noticed some foods hit that point where an extra few minutes completely changes them. Crispy edges, better texture, all that.

For me, frozen mozzarella sticks are a good example. The difference between "okay" and actually crispy can be just a couple extra minutes.

What food have you found that needs that extra time in the air fryer to really turn out right?

I feel like everyone talks about wings, fries, chicken, etc. but there’s always that one random food that turns out way better than expected.

For me, it’s reheating breakfast sandwiches. The outside gets crispy again but the inside stays soft, and it’s way better than throwing it in the microwave.
