Mix the butter with the garlic, honey, parsley, paprika and pepper.
Place the salmon filets on a foil or parchment lined air fryer tray or baking sheet. If using foil, spray with a small amount of cooking spray.
Top each one with the butter mixture and the lemon slices.
Air fry for approximately 11 minutes or bake for approximately 15 minutes. Cooking times will vary based on the size of the salmon filets as well as individual cooking appliances. The salmon is finished when it flakes easily with a fork.
When it is finished, spoon any of the butter mixture that baked off back onto the filets and sprinkle with some more parsley if desired.
