Preheat your air fryer to 400°F (200°C) for about 3-5 minutes.
Grease the air fryer basket with cooking spray or a light coating of oil.
In a large bowl, combine the chilled mashed potatoes, egg, shredded cheddar cheese, chives, flour, garlic powder, salt, and pepper. Mix until well combined.
Roll the mixture into 1-inch balls, then coat each ball in grated Parmesan cheese.
Place the coated potato balls into the greased air fryer basket, leaving some space between each puff to allow for even cooking.
Cook in the air fryer for 10-15 minutes, or until the puffs are golden brown and crisp on the outside. You may need to shake the basket halfway through cooking to ensure even browning.
Once cooked, carefully remove the potato puffs from the air fryer and allow them to cool for a few minutes before serving.
Serve warm and enjoy your delicious Cheesy Mashed Potato Puffs made in the air fryer!
