Fingerling potatoes are one of the best potatoes to roast! Their super thin skin is tasty and nutritious and crisps perfectly when roasted on their own. Delicately crispy skin wrapped around a sweet and creamy flesh that melts in your mouth makes the most delicious oven fries you won't believe you can make at home. Try roasting them in a really hot oven with rosemary, olive oil, and salt and you won't be disappointed.
