Truffle fries are a type of French fries that are flavored with truffle oil or truffle mushrooms. Truffle oil is a neutral oil that has been infused with white or black truffle peelings. The fries are usually prepared by baking, deep-frying, or air frying them. Once the fries are cooked, they are tossed in truffle oil and seasoned with truffle salt or grated parmesan cheese. Truffle fries are often served as a side dish to burgers, steak, or chicken. They can also be served with a dipping sauce, such as parmesan lime aioli. Truffle fries are a popular dish in restaurants and can be made at home with simple ingredients.
