First, combine all of the ingredients for the salmon seasoning. Mix to combine. Set aside. Note that you will have leftover salmon seasoning, so make sure to transfer the leftovers into a jar for later.
Preheat the air fryer to 400ºF. Spray the air fryer basket with non-stick cooking spray.
Pat the salmon steaks with a paper towel to remove moisture and then sprinkle steaks with 1 tablespoon of salmon seasoning. Be sure each steak is coated in seasoning (don’t worry about getting any of the seasoning on the skin).
Place the salmon skin-side down in the air fryer. Drizzle the salmon with the remaining olive oil. Be sure the salmon steaks are not overcrowded or touching (two batches may be needed depending on the size of the air fryer).
Cook the salmon for 7-8 minutes at 400ºF.
Use a fork to test to see if the salmon is done. If that salmon flakes apart easily, remove it from the air fryer. If the salmon is not done, cook it for 1-minute increments until it is done cooking.
Let the salmon rest for 5 minutes and enjoy.
