• Prep and slice the Sweet Potatoes. 

  Peel the potato, cut off the ends, and then slice the sweet potatoes lengthwise into 1/4-inch slices. Then, turn the slices onto their flat sides so that on the cutting board for easier slicing. Slice into uniform-sized fries for even cooking. Uniform slices are essential as they will cook more evenly, and thick potato slices won't get as crispy.
• Toss in cornstarch, if using.

  The cornstarch is optional but does help to crisp the fries even more. Make sure the potato slices are patted dry. Then, put them in a plastic bag with the cornstarch. Shake until all the slices are coated.
• Drizzle and toss the potato slices with oil.

  Then, place the uncooked fries on a baking sheet. Drizzle with the olive oil and add the salt. Toss to make sure that all of the fries are coated in oil.

Air Fryer Sweet Potato Fries

• Preheat the air fryer to 400º F. Arrange the potatoes in a single layer in the air fryer basket. Once the air fryer is heated, cook for 8 to 12 minutes, tossing as needed to make sure that all of the fries cook uniformly. Extend the cooking time until all are cooked evenly. (Note - My air fryer takes 10 minutes, but the time will depend on the size of the sweet potato fries and your particular air fryer.)

Oven Baked Sweet Potato Fries

• Preheat the oven to 425º F. Arrange the potatoes in a single layer on a baking sheet. Once the oven is heated, cook them for 20 minutes. Turn the fries using a metal spatula and cook for 10 – 15 more minutes. Watch the fries closely at this stage as they can burn easily.
