Place the sliced potatoes in a large bowl with cold water.
Allow the potatoes to soak in the water for at least 30 minutes, preferably an hour.
Spread the fries onto a flat surface and dry them completely with paper towels. Coat them with 1 tbsp of the white truffle oil and seasonings.
Add half of the fries to the Air Fryer basket. Adjust the temperature to 380 degrees and cook for 15-20 minutes. Set a timer for 10 minutes and stop and shake the basket at the 10-minute mark (once).
Use your judgment. If the fries need to be crisper, allow to cook for additional time. If the fries look crisp prior to 15 minutes, remove them. I cooked both of my batches for almost 20 minutes.
When the first half finishes, cook the remaining half.
Add the remaining truffle oil and parmesan to the fries immediately upon removing them from the Air Fryer.
Top with shredded parsley. Serve!
