Burgers in the air fryer
A burger in an air fryer behaves a little like a burger on a grill grate. Rendered fat falls through the basket instead of pooling under the patty, so the whole surface stays in dry moving air. That dry air is what builds the crust: it strips surface moisture first, then browning follows, and it follows sooner than it would on a sheet pan at the same dial.
The outcome is decided in two places at once. The crust is surface work, and the fan handles it. The center is a conduction problem: heat still has to walk to the middle, and ground beef has to be cooked through, so the center sets the finish even when the outside looks ready early. Frozen patties go straight in; the cold middle simply needs more of that time.
Spacing decides the rest. Patties that touch trade dry air for each other's steam, and the facing edges turn gray instead of brown. Leave clear space around each one and cook a second batch rather than crowding; the first batch holds fine under foil.
The numbers
| Oven recipe | Air fryer | First check |
|---|---|---|
| Fresh patties from a standard recipe425 °F for 20 min | 400 °F for 13 min | 9 min |
| Frozen patties from the box400 °F for 25 min | 375 °F for 16 min | 11 min |
These are starting numbers, quoted a little short on purpose: checking early and adding a minute beats scraping off a burnt layer. The converter on the front page adjusts them for a specific machine and keeps refining them from ratings.
Which picture to pick
Pick Thick, the middle picture. Bacon and flatbread are nearly all surface, but a patty half an inch or more deep has a real interior that heat can only reach by conduction, and no fan speeds that part up. Thick gives the surface the fan's full advantage while holding enough time for the center to catch up. Even a fairly thin patty belongs here, because ground beef has to cook through to the middle, not just brown on the outside.
What makes the difference
- Press a dimple into the center of each fresh patty before it goes in; patties plump as they cook, and the dimple keeps the top flat enough to hold cheese and a bun.
- Put a spoonful of water in the drawer under the basket; burger fat renders quickly, and the water keeps the drippings from smoking before the patties are done.
- Cheese goes on in the last minute, pressed lightly onto the patty, or the fan will lift a loose slice right off the burger.
- Check the temperature from the side, thermometer parallel to the patty, so the tip sits in the true center rather than passing through it.
- Toast the buns cut side up in the empty basket for the last minute while the patties rest.
Safety
Ground beef must reach 160 °F (71 °C) minimum internal temperature, the USDA figure. There is no rare or medium rare option for a burger; grinding spreads surface bacteria through the whole patty, so the center itself has to hit the number. Full food safety guide
Run your own recipe
Take the oven directions above, or the ones on the package, to the converter on the front page and pick Thick. The quoted time errs a little short and comes with an earlier first check; a burger can always take another minute, and it cannot give one back. Rating the cook afterward tunes the numbers to that machine.
