How to Reheat Pizza in an Air Fryer
A microwave steams pizza from the inside out, which is why the crust turns chewy and limp no matter how careful you are with the timer. An air fryer does the opposite — it circulates hot air around the slice, so the crust re-crisps at the same time the cheese re-melts, closer to fresh than either a microwave or a slow trip through a full-size oven.
The method below works for thin crust, thick crust, and deep dish leftovers, with a separate note for slices going in straight from the freezer.
Why an air fryer beats the microwave or the oven here
A microwave heats the moisture inside the slice first, which turns the crust soft and sometimes rubbery by the time the center is actually hot. A conventional oven avoids that but takes 10-15 minutes to fully preheat for what should be a 2-minute reheat job.
An air fryer's fan moves hot air directly across the top of the slice, so the crust and cheese crisp back up in the same few minutes it takes the center to warm through — no preheat wait, no soggy bottom.
Temperature and time
350°F for 3-5 minutes is the right range for most refrigerated leftover slices, with no oil needed. Thin crust slices are usually done at the 3-minute mark; thick crust or deep dish slices need closer to 5 minutes since there's more to heat through.
Check at the lower end of the range the first time you reheat a given pizza style, since basket size and how cold the slice was going in both shift the result by a minute or so.
Step-by-step
1. Place the slice (or slices, in a single layer with space between them) directly in the basket or on the tray — no foil or parchment needed for a plain reheat. 2. Set the air fryer to 350°F. 3. Cook for 3 minutes, then check: the cheese should be re-melted and the crust should feel firm, not soft, when you lift an edge. 4. If it needs more time, add 1-2 minutes rather than restarting the full cycle, since pizza goes from reheated to overly dry fast once the cheese is already melted.
Getting a crispy crust without drying out the toppings
Don't stack slices on top of each other — a stacked slice traps steam against the crust underneath it, which undoes the whole point of using an air fryer instead of a microwave. Reheat in batches if your basket isn't wide enough for everything in one layer.
If the crust is crisping faster than the cheese is melting (common with thin crust at a slightly higher temperature), that's normal — pull it as soon as the cheese looks right rather than chasing a specific crust texture, since cheese overcooks faster than crust dries out.
Reheating pizza straight from frozen
A leftover slice frozen flat can go straight into the basket without thawing first — add roughly 2-3 extra minutes at the same 350°F, checking at the original 3-5 minute mark and then in 1-minute increments after that.
Frozen slices benefit from a lower rack position or more space around them than fresh leftovers, since the air needs more time to reach the still-cold center before the crust and toppings finish crisping.
Frequently Asked Questions
- What temperature should I use to reheat pizza in an air fryer?
- 350°F for 3-5 minutes works for most leftover slices — thin crust toward the shorter end, thick crust or deep dish toward the longer end. Check the first time and adjust by a minute based on how your air fryer runs.
- Do I need to preheat the air fryer first?
- It's not required for pizza specifically — a cold start adds roughly a minute to the total time, which is still faster than waiting for a full-size oven to preheat.
- Can I reheat pizza straight from the freezer in an air fryer?
- Yes — place the frozen slice directly in the basket, no thawing needed, and add about 2-3 extra minutes at 350°F compared to a refrigerated slice, checking in 1-minute increments once you're past the original time range.
