Brush the salmon filets with the oil on both sides.
Season well on both sides. (The seasonings listed are only a suggestion. Feel free to use any kind that you like!) Salmon is very versatile and goes well with a lot of flavor profiles!
Make a small aluminum foil boat, or use an air fryer liner, and place the salmon in it.
Air fry at 400 for 9-11 minutes.
You can tell it is done when you gently press down on the thickest part of it with a fork and it flakes easily.
Melt about a teaspoon of butter on each filet when they are finished cooking and squeeze on some fresh lemon juice. Serve hot and enjoy!
