Wash and scrub the potatoes under cold running water, then pat dry. Cut in half lengthwise, then into long strips about ¼-inch thick.

In a deep pot or Dutch oven, heat about 3 inches of oil until it reaches 250º. Line a baking sheet with paper towels and set near the stove. One handful at a time, add fries and cook until tender but still pale. Remove with a slotted spoon or spider. Drain on paper towels and repeat with remaining fries. Once all fries are cooked, refrigerate until cool.

While the fries are cooling, combine rosemary, thyme and salt in a small bowl and set aside.

Increase the temperature of the oil until it reaches 350º. Line the baking sheet with fresh paper towels. Repeat frying process, this time cooking until fries are golden and slightly crispy. Sprinkle herb mixture over fries while they’re still hot. Serve immediately.
