Wash and dry your potatoes thoroughly. Place each potato between two wooden spoons or chopsticks and carefully slice thin slits (about ⅛ inch apart) down the length of the potato. The spoons will help stop your knife from cutting all the way through.

In a small bowl, mix olive oil, salt, pepper, and garlic powder. Brush this mixture generously over the potatoes, making sure it seeps into each slice. You can gently fan out the slices to get the seasoning inside.

Preheat your air fryer to 375°F (190°C). Place the seasoned potatoes into the air fryer basket, cut side up. Air fry for 20–25 minutes, checking halfway to brush on more olive oil if needed.

After 20–25 minutes, drizzle melted butter over the potatoes and cook for an additional 5–7 minutes until golden and crispy. Insert a knife into the center to check for tenderness.

Carefully remove the potatoes and sprinkle with fresh herbs if desired. Serve hot, and prepare for lots of compliments.
