Gather your ingredients. Preheat oven to 450 degrees.
Rinse and dry your sweet potatoes. Cut them lengthwise and slice them 1/2 inch thick, cutting them into small pieces, 3 inches long.
Place potatoes in a medium sized bowl. Drizzle with olive oil and mix to coat.
Sprinkle with coarse sea salt.
Spread the potatoes out evenly on a baking sheet, lined with parchment paper.
Roast for 20-25 minutes, turning them over 1/2 way through until the potatoes are browned on the edges and tender.
While the fries are cooking, roughly chop 2 tablespoons of parsley.
Mince 1 clove of garlic.
Grate 3 tablespoons of Parmigiano-Reggiano Cheese.
Toss warm fries with cheese, parsley + garlic.
