Equipment

air fryer
mandoline (optional)

Ingredients

16 oz sweet potatoes (2-3 large, or 3-4 medium-to-small potatoes)
1-2 Tbsp avocado oil
½ tsp salt
black pepper to taste
(optional: 1 Tbsp cornstarch)

Instructions

Optional: Peel sweet potatoes if desired.
Cut sweet potatoes into fries using a mandoline or knife. First, cut off both ends of the sweet potato, then cut it in half lengthwise. Next, slice the potato lengthwise into slices ¼-⅜-inch thick. (I used a mandoline with the slicer on the largest setting.) Finally, use a knife to cut each slice into sticks for fries. (Smaller fries will turn out crispier!)
Preheat air fryer to 370°F (190°C) if needed. (To keep fries warm after they cook, preheat your regular oven to 180°F / 80°C.)
Optional: Add fries to a sieve or colander and rinse with cold water. If you want to soak the fries, transfer them into a bowl and fill with in cold water, so they’re completely submerged. Let fries soak while air fryer preheats, or as long as you prefer.
Pat fries dry with paper towels. Get them as dry as possible!
Toss sweet potato fries with oil, salt, & pepper in a bowl.
Add seasoned fries to bottom of preheated air fryer basket, in a single, even layer so they’re not stacked or overcrowded. (Cook the fries in batches as needed. Taking the time to cook more batches will make them crispier in the end!)
Air fry sweet potato fries for 20-25 minutes, until crisp and golden-brown. (You can flip them halfway if you want, but I usually don’t, and they turn out great!) If desired, season cooked fries with additional salt or seasonings.
To keep them warm, add cooked fries to a wire rack on a baking sheet and transfer to a preheated oven (180°F) while you air fry the remaining fries. (Or, you can reheat all of your cooked fries in the air fryer for 2-3 minutes to refresh them before serving.)
Serve hot and enjoy!
