Add all the listed ingredients (except for the salmon filets) into a large ziplock bag and mix.
After the ingredients are mixed, add the salmon filets and let them rest for 10 minutes up to an hour or overnight in the fridge.
In the meantime prepare the nut topping (this step is optional). Add the listed nuts into a food processor and mix until ground. Add the ground nuts on top of the seasoned salmon.
Place the seasoned salmon (optional together with the nut topping) in the air fryer and fry for 7 minutes at 200 degrees Celcius / 390 degrees Fahrenheit.
