Preheat air fryer to 400˚F. Once preheated, spray the air fryer basket with cooking spray.
Pat the scallops dry and season well with salt and pepper on both sides. Place the seasoned scallops in the air fryer. Cook for 6 to 7 minutes (for really thick scallops, 8 minutes). Flip halfway through the cook time.
While the scallops are air frying, melt butter with garlic, lemon zest, and chives in a saucepan over medium heat. Sauté for 2 to 3 minutes until fragrant.
Serves scallops with butter drizzled on top.
notes
*If you would like to serve the scallops with linguine or your favorite pasta, I recommend doubling the sauce so you can also dress the paste with the sauce!
