Ingredients

2 medium-large sweet potatoes about 1.5 lbs / 680 g
4 cups cold water for soaking
1 1/2 tbsp cornstarch
1 1/2 tbsp extra-virgin olive oil or avocado oil
1 tsp garlic powder
1/2 tsp smoked paprika
1 tsp kosher salt divided
1/2 tsp black pepper

Instructions

Peel the sweet potatoes and cut them into 1/4-inch (6 mm) thick sticks of even size.
Soak the fries in 4 cups of cold water for 30 to 45 minutes.
Drain, rinse and roll the fries between clean towels until completely dry.
Toss the dry fries with the cornstarch for 60 seconds, until evenly coated.
Drizzle with the oil and toss until glossy, then add the garlic powder, paprika, 1/2 tsp salt and pepper and toss again.
Preheat the air fryer to 380°F (193°C). Air fry half the fries in a single layer for 12 to 14 minutes, shaking at 6 minutes.
Sprinkle with some of the remaining salt right away. Repeat with the second batch and serve hot.

Notes

Cook in two batches so the fries crisp instead of steaming. Reheat leftovers in the air fryer at 380°F (193°C) for 3 to 5 minutes. For the oven, bake at 425°F (220°C) on lightly oiled sheets for 25 to 30 minutes, flipping halfway.
