Press the tofu for 15 to 30 minutes either with a tofu press or by wrapping it in a kitchen towel then placing something heavy on top.
Cut the tofu into 1-inch cubes and transfer it to a medium bowl.
Add tamari, sesame oil, and all the seasonings, and toss carefully to thoroughly coat the cubes.
Sprinkle in the cornstarch and toss once more.
Spray the air fryer basket with cooking oil and then spread the seasoned tofu cubes across the basket, ensuring they’re in a single layer with space between each piece for airflow.
Air fry the tofu at 400 °F/200 °C for about 11 minutes, shaking the basket after 5-6 minutes.
Check it at 10 minutes. It may take anywhere between 10-13 minutes total for your desired crisp level.
Serve with Yum Yum sauce or any dipping sauce of choice.
