Prepare the Potatoes: While the air fryer is preheating, wash, peel (optional), and cut the potatoes into thin strips or wedges. Place the diced potatoes into a large bowl filled with cold water. Let the potatoes soak for 30-40 minutes. Then, remove the potatoes from the water and pat them dry with a paper towel to remove excess moisture.

Season with Truffle Oil: Place the cut potatoes in a mixing bowl and drizzle them with truffle oil. Toss the potatoes to ensure they are evenly coated with the oil. Truffle oil is potent, so use it sparingly, adding more as needed for your desired truffle flavor.

Season with Salt and Pepper: Season the truffle-coated potatoes with a pinch of salt and freshly ground black pepper. You can also use truffle salt to intensify the truffle flavor.

Preheat the Air Fryer: Preheat your air fryer to 380 degrees F (193°C) for 3-5 minutes.

Air Fry: Carefully place the seasoned potato slices or wedges in a single layer in the air fryer basket, ensuring they are not overcrowded. If necessary, cook in batches.

Cook: Cook the truffle fries in the preheated air fryer at 380 degrees F (193°C) set cook time for 15-20 minutes, shaking the basket or flipping the fries halfway through to ensure even cooking. Cook until the fries are golden brown and crispy.

Sprinkle with Parmesan: About 1-2 minutes before the cooking time is done, open the air fryer and sprinkle the fries with freshly grated Parmesan cheese. Close the air fryer and let it finish cooking.

Garnish and Serve: Remove the truffle cooked fries from the air fryer basket once they are done. Garnish with chopped fresh parsley (optional) for color and freshness. Add a little truffle oil, right before serving.

Serve Hot: Serve the truffle fries immediately while they're hot and crispy. They're perfect as a side dish, appetizer, or snack.

Enjoy the irresistible aroma and flavor of truffle fries made effortlessly in your air fryer. It's a gourmet treat you can enjoy at home anytime!
