How To Reheat A Pie In The Air Fryer | Crispy Crust Secrets

A leftover pie slice deserves better than the microwave. You know the outcome: a soggy, gummy crust and filling that scalds your tongue in spots while staying cold in others. The oven takes twenty minutes and heats up the whole kitchen.

The air fryer reheats pie using circulating hot air, which crisps the exterior while warming the interior evenly. Getting the right result depends on matching temperature and time to the type of pie — whole, slice, frozen, or potpie. This guide covers the best settings so your leftover slice or pan of pie tastes nearly as good as the first bite.

The Basic Method: Half a Pie

The strongest approach comes from Serious Eats, which tested reheating a half-pie in an air fryer. Preheat the basket for about 3 minutes until it reaches 350°F (175°C). Wrap the pie pan tightly with foil, place it in the basket, and heat for about 12 minutes, or until the filling is warm throughout.

The foil prevents the crust from over-browning while the cold filling catches up. It also traps steam so the interior reheats gently. This method works for any fruit or custard pie that was originally baked in a metal or disposable foil pan.

If you’re reheating a whole pie, you can adapt the same technique. Just increase the time in 5-minute increments, checking the filling temperature with a thermometer — you want at least 165°F for savory pies or warm throughout for sweet ones.

Why Heat Settings Matter

Pies vary wildly in crust thickness, filling density, and whether they start cold or frozen. A thin, flaky crust needs less heat than a thick, dense one. A frozen pie needs a much longer cook time than a refrigerated slice. Assuming one setting works for every pie guarantees burnt edges or a cold center.

Here’s how different pie types affect your air fryer approach:

• Thick crust pies: A sturdy double-crust or deep-dish pie needs a lower temperature (320°F) and a shorter window (3–5 minutes per slice) to avoid burning the outside while the inside warms.
• Toppings-heavy pies: Pies with streusel, meringue, or a crumb top benefit from around 325°F for 5 minutes. The lower temp keeps the topping from darkening too fast.
• Pot pies: A pot pie’s top crust browns quickly while the bottom stays underdone. Home cooks recommend lowering the temperature and extending the time to allow the filling to heat through without scorching the top.
• Frozen pies: A whole frozen pie needs a much longer cook — think 310°F for 40 to 50 minutes. The low temperature gives the frozen center time to thaw and warm without burning the crust.
• Ready-made pies: Some commercial pies, like Wilfred’s Pies, recommend 160°C (320°F) for 30 minutes. Always check the package for specific guidance.

The general air fryer reheating sweet spot for most foods sits between 320°F and 400°F. For pies, you almost always want the lower half of that range to protect the pastry.

Temperature and Time By Pie Type

Different pie forms need different settings. One detailed guide from frozen pie timing walks through reheating a frozen apple pie at 310°F for 40 to 50 minutes — a useful benchmark if you’re starting from frozen. Here’s a quick reference for the most common scenarios:

These times assume the pie fits in your basket without touching the heating element. If your air fryer runs hot, drop the temperature by 10°F and check earlier. A digital thermometer inserted into the filling is the most reliable way to tell when it’s ready.

How To Reheat A Single Slice

Reheating one slice is the most common need. The goal is a warm, crisp crust without burning the edges. Follow these steps:

1. Preheat your air fryer to 320°F (160°C). A lower temperature prevents the thin slice from drying out or burning while the filling warms.
2. Place the slice directly in the basket, unwrapped. Air needs to circulate around all sides. If the slice is very delicate, line the basket with a piece of foil for easier removal.
3. Heat for 3–5 minutes. Check at 3 minutes. If the crust is golden and the filling feels warm when you touch the bottom, it’s done. Thicker slices may need a full 5 minutes.
4. Let it rest for 1 minute. The filling retains heat and can be dangerously hot immediately after. A short rest evens out the temperature.

This method works for apple, cherry, pecan, and most fruit pies. For custard or cream pies, skip the air fryer — the low, even heat of a countertop oven is gentler and prevents the filling from separating.

Pro Tips For Better Results

A few small adjustments separate a good reheat from a great one. Cosori’s general reheating guide suggests a temperature of 320°F for thick-crusted pies — its thick crust temperature advice works well for dense fillings too. Here are other tricks to keep in mind:

One common mistake is assuming a single high temperature works for all pies. A pot pie, for example, often burns on top before the bottom sets because the filling takes longer to heat. Using a lower temperature and longer time solves this — some home cooks find 320°F for 15–20 minutes gives the filling enough time without scorching the crust.

If your pie has a very wet filling (like a fruit pie that’s been refrigerated for a few days), you may notice the bottom crust stays soft. Placing the slice on a piece of parchment or a silicone liner helps wick moisture away and adds a bit of bottom crisp.

The Bottom Line

Reheating pie in the air fryer comes down to matching the method to the pie. Wrap half pies in foil at 350°F for 12 minutes. Handle single slices unwrapped at 320°F for 3–5 minutes. Frozen whole pies need longer at 310°F. Keep the temperature on the lower side, check often, and rely on a thermometer when in doubt.

For that leftover slice from Saturday’s bake, popping it in the air fryer at 320°F for four minutes gives you a crispy crust and a warm, not scorched, filling — no microwave science experiment needed.
