Step 1

Arrange rack in the middle of the oven and heat to 400°F.

Peel the sweet potato and cut it into 1/4-inch-thick sticks or wedges.

Place the sweet potato in a large zip-top plastic bag, add the cornstarch and 1/2 teaspoon salt, and shake to combine. (Alternatively, place everything in a large bowl and toss together.)

Add the 3 tablespoons of oil to the bag or bowl and toss vigorously to coat.

Coat a rimmed baking sheet with oil. Spread the coated sweet potato wedges out into a single layer on the baking sheet.

Roast 15 minutes. Using a flat spatula or turner, flip the sweet potatoes and continue to roast until the fries are tender on the inside and crispy on the outside, 5 to 10 minutes more.

Sprinkle with additional salt if desired before serving.


These sweet potato fries are best eaten the day they are made.
