Tofu in the air fryer
Tofu is a sponge of water held in a mild protein net, and the water is the whole story. Crisp tofu is a drying project before it is a browning project: the surface must give up its moisture before any color can form, so every bit of water pressed out ahead of time is work the hot air does not have to do. Pressing decides more of the result than any number on the dial.
The air fryer suits tofu because moving air is very good at drying. In a still oven the cubes sit in their own humidity and crisp slowly; the fan carries that damp layer away and dries every face at once. Tofu brings no fat of its own, so a light toss in oil gives the browning something to work with, and a dusting of cornstarch dries into a thin shell that crisps the way a fried coating does.
The middle needs almost nothing. Tofu leaves the package already cooked, so the inside only has to warm through while the outside dries and colors. Crowding is the main failure: stacked cubes trade moisture back and forth and steam instead of crisping. One layer with air around each piece is most of the technique.
The numbers
| Oven recipe | Air fryer | First check |
|---|---|---|
| Standard baked tofu cubes400 °F for 30 min | 375 °F for 19 min | 14 min |
| Faster high heat cubes425 °F for 25 min | 400 °F for 16 min | 11 min |
| Tofu slabs or steaks400 °F for 35 min | 375 °F for 22 min | 16 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. A tofu cube is not flat like bacon; it has a real interior the heat still has to reach, even if that interior only needs warming through. It is not deep either, since nothing about a one inch cube makes the middle set the pace. Thick matches the way a cube actually cooks: strong surface drying from the fan, with a modest allowance for heat walking to the center.
What makes the difference
- Press firm or extra firm tofu under a weight for 20 to 30 minutes before anything else; most of the crust is decided before the basket ever heats.
- Skip soft and silken tofu; only firm and extra firm hold their corners through a shake.
- After pressing, toss the cubes in a little oil and then a spoonful of cornstarch; the starch dries into a shell that crisps and later grips sauce.
- Shake twice, once at the early check and again a few minutes later; tofu browns only where hot air touches it, and each shake turns new faces up.
- Sauce after cooking, not before; a wet marinade soaks pressed water right back in. Toss the finished cubes with sauce off the heat so the crust survives.

Those baselines are starting points. Enter the recipe actually in hand on the front page, choose the Thick picture, and the converter quotes a setting with an earlier first check, since tofu can always take another minute. Rate the cook, and the next batch starts closer to just right.
