Step 1

Preheat an air fryer to 425 degrees F (220 degrees C) according to manufacturer's instructions. Line the basket with nonstick foil.

Step 2

Pierce the potato several times with a paring knife. Microwave on high power until very soft, 7 to 10 minutes, flipping halfway through to ensure even cooking. Remove and let cool enough to handle.

Step 3

Use a serrated knife to carefully slice potato in half lengthwise. Slice each half into 4 wedges, then cut the wedges in half. Drizzle with oil and brush to coat.

Step 4

Place the potatoes close together in the air fryer with the skin resting on the foil and the cut-sides exposed to the air. Sprinkle with Parmesan cheese, garlic powder, and Italian seasoning, then move the slices apart. (Starting with them close together helps you get more of the cheese and seasonings on the potatoes.)

Step 5

Air-fry until golden brown, about 20 minutes, checking every 5 minutes. Reduce air fryer temperature to 350 degrees F (175 degrees C). Continue to air-fry until well browned and crispy, about 5 minutes more.
