Indulge in a gourmet treat with truffle parmesan air fryer french fries. Cut the potatoes into thin strips and toss them with olive oil, truffle oil, grated parmesan cheese, salt, and pepper. Preheat the air fryer to 400°F (200°C) and cook the fries in a single layer for 15-20 minutes, shaking the basket occasionally. Sprinkle with chopped parsley and additional parmesan cheese before serving.
