Add your marinade ingredients to a bowl. Whisk to blend.
Lay your salmon out in a dish. Cover with plastic wrap and place in the refrigerator. Pour the marinade over the salmon. Let your salmon marinate a minimum of 30 minutes.
If you are planning to marinate the salmon with the honey garlic marinade overnight, use a ziplock-style bag so the salmon doesn't dry out. Add your salmon pieces and pour in the marinade. Seal the bag and place it in the refrigerator.
Spray oil on the bottom of the air fryer. Place your marinated salmon in the air fryer. Spray oil over the salmon and close the air fryer.
Air fry your salmon for 10 minutes at 365º F.
Carefully remove the salmon with a plastic spatula. (Don't use metal because you can scratch the non-stick surface.)
You can use any cut of salmon, try to get de-boned. I highly recommend using wild salmon. Farmed salmon doesn't have the same rich flavor.
Use tamari, gluten-free soy sauce, or coconut aminos. They all have roughly the same flavor. Use coconut aminos if you can't have soy.
This salmon will keep fresh in an air-tight container in the refrigerator up to 4 days.
