Elevate your air fryer French fries with the luxurious flavor of truffle oil. Start by cutting potatoes into thin strips and soaking them in cold water for about 30 minutes. Drain and pat them dry, then toss with olive oil, truffle oil, salt, and pepper. Preheat the air fryer to 400°F (200°C) and cook the fries in a single layer for about 15-20 minutes, shaking the basket halfway through. The result is crispy fries with a subtle and earthy truffle aroma. Serve them as a gourmet side dish or as a fancy snack!
