While the air fryer is preheating, slice your tempeh into cubes about 1” thick.
To marinade the tempeh, place cubes in a medium sized bowl and add remaining ingredients. Marinade for up to 30 minutes, or if you think of it, you can marinade overnight.
Spread tempeh out into even layer in air fryer tray.
Air fry for 12 min, or until desired crispiness.
Let cool and add marinade over crispy tempeh cubes and enjoy!
Notes
Peanut marinade adapted by Minimalist Baker.I prefer to add the seasoning AFTER cooking the tempeh because it seems to coat the tempeh better/more. But you can also make the tempeh marinade and coat the tempeh before air frying. If doing so, allow at least 30 minutes for the tempeh to sit in the marinade.
