Deep dish pizza is a glorious thing—when it's fresh. But leftover slices often go downhill fast: cold, congealed cheese, a butter-soaked crust that's gone limp, and toppings that slide off in one sad lump. If you've ever tried rescuing it in a microwave, you already know the result: rubbery cheese and a crust that bends like cardboard.
The air fryer changes that. By circulating hot air at high speed, it crisps the exterior, warms the thick center, and brings leftover deep dish remarkably close to its original glory. And it takes about seven minutes. You can also read our guide on best size air fryer for family of.
This guide covers every step of reheating deep dish pizza in an air fryer—preparation, temperature, timing, and the small blunders that ruin the outcome. No guesswork, just honest tips that actually work.
Why the Air Fryer Is the Best Way to Reheat Deep Dish Pizza
Deep dish presents a unique reheating challenge: it's thick, dense, and loaded with toppings. A microwave heats the filling but turns the crust into a damp sponge. A conventional oven works, but it takes 15 to 20 minutes and often dries out the cheese on top. You can also read our guide on how to clean grease from air fryer.
The air fryer sits right in the middle. It strips moisture from the crust's surface so it turns crisp, while the interior gets enough time to warm through without burning.
Here's how the main reheating methods compare:
| Method | Crust | Cheese | Time |
|---|---|---|---|
| Microwave | Soggy, chewy | Rubbery | 1–2 minutes |
| Conventional oven | Crisp | Dries out | 15–20 minutes |
| Stovetop pan | Crisp on the bottom only | Uneven | 8–10 minutes |
| Air fryer | Crispy all around | Melty and even | 5–9 minutes |
Step 1: Prepare the Pizza Before Reheating
Thaw Frozen Pizza First
If you froze your deep dish, don't drop it straight into the air fryer. A frozen slice cooks unevenly—the edges will burn before the center defrosts. Move it to the refrigerator the night before, or at minimum, let it sit on the counter for 20 to 30 minutes before reheating.
Cut Large Slices Down
Deep dish slices are hefty. If your air fryer basket is smaller than about 5 quarts, cut each slice into halves or thirds. Smaller pieces heat faster, cook more evenly, and fit without overlapping. Overlapping blocks airflow and leads to hot spots—the exact problem you're trying to avoid.
Let It Rest Briefly
Give the pizza five minutes at room temperature before it goes in. This gentle temperature equalization helps the cheese and butter warm gradually instead of separating or turning greasy. It also reduces the chance of the crust steaming instead of crisping.

Step 2: Set the Right Temperature
Set your air fryer to 350°F to 375°F (175°C to 190°C). This range is the sweet spot.
- Above 400°F: The cheese scorches before the center warms through.
- Below 325°F: The crust turns chewy instead of crisp, and reheating drags on.
If your air fryer has a reheat preset, it typically lands around 350°F—which works well. Otherwise, set the temperature manually. It takes ten seconds and makes a real difference.
Step 3: Time It Correctly
The exact reheating time depends on the pizza's thickness, your air fryer's wattage, and whether it was refrigerated or frozen.
Use these as starting points at 375°F:
- One standard slice: 5–7 minutes
- Two or three slices: 7–9 minutes
- Extra-thick deep dish: up to 10 minutes
Start checking at the 5-minute mark. It's easy to add time—impossible to take it back. When you're reheating a second batch, the air fryer is already warm, so it cooks slightly faster—trim a minute off the clock.
Step 4: Check for Doneness
The pizza is ready when:
- The crust is golden brown and crisp to the touch
- The cheese is fully melted and just beginning to bubble
- A fork poked into the center comes out hot
If the edges look done but the center is still cool, add 1–2 minutes at the same temperature. Resist the urge to crank the heat—that just burns the exterior while the inside stays cold.

Pro Tips for a Better Reheated Slice
Sprinkle on Fresh Cheese
A small handful of shredded mozzarella or provolone on top before reheating melts into a fresh, gooey layer. It also protects the original cheese from drying out during the air frying cycle. If you enjoy experimenting with melted cheese beyond pizza, the approach for baked camembert follows the same principle—layering fresh cheese over an existing base elevates the whole dish.
Brush the Crust with Butter
Melt a little butter and brush it over the exposed top crust before reheating. The butter aids browning and adds flavor back, especially if the pizza has been in the fridge for a day or two.
Don't Overload the Basket
Air fryers work because air circulates around every surface of the food. When you cram multiple slices in, airflow drops, heating becomes uneven, and you get slices that are burnt at the edges and cold in the middle. Cook in batches if needed. One perfect slice at a time beats three mediocre ones.
Why Air Circulation Is Everything
Deep dish pizza is dense—one of the densest styles you can reheat. Proper air circulation is the difference between a crispy crust and a steamed, chewy one. That's why stacking, overlapping, or overcrowding the basket ruins the result faster than any other single mistake.
If reheating pizza fills your kitchen with smoke, check how well your exhaust setup is performing. Without adequate ventilation, smoke and grease particles can linger for hours. A weak vent is often caused by grease that has built up over time—periodic range hood maintenance keeps airflow working as intended, and for kitchens without external ducting, a well-chosen ventless exhaust system can make a noticeable difference.
Is It Safe to Reheat Leftover Pizza?
Yes—but only if the pizza has been handled properly. Leftover pizza should be refrigerated within two hours of cooking, and reheated to an internal temperature of 165°F to destroy potentially harmful bacteria. The USDA food safety guidance is clear on this: when in doubt, throw it out.
If your pizza sat at room temperature longer than two hours, don't risk it—toss it. Reheating won't kill all bacteria that may have formed. Likewise, if the pizza is several days old, give it a close inspection. A dry surface, off odor, or any visible mold means it's past its prime.

Common Mistakes to Avoid
Cramming the Basket
Stacked slices mean poor airflow and uneven heating. Always leave space between pieces.
Blasting the Heat
400°F and above burns the cheese before the center warms. Keep it between 350–375°F.
Skipping the Thaw
Frozen pizza in the air fryer results in a burnt crust and a frozen center. Thaw first.
Overcooking Until Dry
Deep dish has a lot of exposed surface area. Leave it in for too long and you'll get a dry, hard crust and tough cheese. Check early and often.
Using Foil Incorrectly
You can use foil to catch drips, but keep it loose and never cover the basket's holes entirely. Blocking airflow defeats the entire purpose of air frying.
Cutting with a Dull Knife
A dull blade crushes the toppings and drags the cheese across the slice. A sharp knife cuts cleanly in one pass, which keeps the structure intact. If you're looking to upgrade, the edge retention and grip of your current knives matter more than brand names.
How to Clean Your Air Fryer After Reheating Pizza
Pizza leaves a mess—grease splatters, cheese drips, and the occasional burnt-on spot. If you leave the basket sitting, that residue bakes on and becomes much harder to remove later.
After reheating pizza:
- Unplug the air fryer and let it cool completely.
- Remove the basket and wash it in warm, soapy water.
- Scrub any stuck-on cheese or grease with a soft sponge or brush.
- Wipe down the interior with a damp cloth.
- Dry all parts fully before reassembling and storing.
For stubborn grease, a paste of baking soda and water works well without scratching nonstick surfaces—avoid abrasive scrubbers entirely. If messes from frequent cooking keep building up beyond the air fryer, consider simple oven protection to catch drips and spills before they become baked-on problems. Leftover food residue is one thing, but airborne grease that settles in your kitchen exhaust is another—over time, it coats every surface in a sticky film.
Final Thoughts
Reheating deep dish pizza in an air fryer is one of the easiest wins in the kitchen. It's faster than the oven, better than the microwave, and simple enough to do on a busy weeknight.
The formula, in short:
- Temperature: 350–375°F
- Time: 5–9 minutes, depending on thickness and quantity
- Prep: thaw if frozen, cut down to size, don't overload the basket
- Check: start verifying at the 5-minute mark and adjust from there
Once you get this right, leftover deep dish will taste close to fresh-baked—crisp on the outside, molten in the middle, and nothing like the rubbery microwave version.

FAQ
Can You Reheat Deep Dish Pizza in an Air Fryer?
Yes. The air fryer's rapid hot air circulation crisps the crust and melts the cheese evenly in roughly 5–9 minutes.
How Long Do You Reheat Pizza in an Air Fryer?
Most standard deep dish slices take 5–7 minutes at 375°F. Thicker slices or larger quantities may need up to 10 minutes.
What Temperature Should I Use for Reheating Deep Dish Pizza?
Set the air fryer to 350–375°F. Higher temperatures burn the cheese before the center warms, while lower temperatures leave you with a chewy crust.
Do You Need to Preheat an Air Fryer for Pizza?
Preheating helps the crust crisp faster, but it's optional. If you do preheat, two to three minutes at 375°F is enough before placing the pizza inside.
Can You Use Aluminum Foil in an Air Fryer for Pizza?
Yes, as long as it doesn't block air circulation. Use a small piece under the slice to catch cheese drips. Never cover thebasket's holes entirely. Blocking airflow prevents the crust from crisping up properly—and it also risks scratching the nonstick coating if the foil shifts around during cooking.
If you're reheating a very thick slice, try placing a small ring of foil under the crust to catch any cheese that drips over the edges. Keep it flat, keep it loose, and remove it as soon as the pizza comes out so it doesn't trap steam underneath.
That's the whole method: prepare the slice, set 350–375°F, check at the five-minute mark, and never overcrowd the basket. Do that, and your leftover deep dish will come out crisp, molten, and genuinely satisfying—close enough to fresh-baked that you might start ordering pizza just so you can reheat it.
