Grease the Air Fryer Basket with cooking spray and then slide inside.
Adjust the temperature of Air Fryer to 360 °F to preheat for 5 minutes.
In a bowl, blend together the tofu, arrowroot flour, and sesame oil.
After preheating, arrange the tofu cubes into the greased Air Fryer Basket in a single layer.
Slide the basket into Air Fryer and set the time for 20 minutes.
While cooking, flip the tofu cubes once halfway through.
Meanwhile, for sauce: in a medium-sized bowl, add all ingredients except for scallions and whisk until well blended.
After cooking time is finished, remove the tofu cubes from Air Fryer.
Transfer the tofu into a non-stick wok with sauce over medium heat and cook for about 3 minutes, stirring occasionally.
Serve hot.
