Start by washing and peeling the sweet potatoes. For a rustic feel, leave some skin on.
Soak the sweet potato matchsticks in cold water for about 30 minutes. This step helps remove excess starch, resulting in crispier fries.
Drizzle the sweet potato fries with olive oil to promote that golden crispiness. Don't be shy – a light coating is the key.
Preheat your air fryer to around 380-400°F (190-200°C). Preheating ensures the fries start cooking immediately, contributing to their crispy texture.
Arrange the seasoned sweet potato fries in a single layer in the air fryer basket. Crowding can lead to uneven cooking, so give them some space to crisp up.
Midway through cooking, shake the basket or flip the fries. This step guarantees that every side gets that delightful crunch.
Enjoy your sweet potato fries when they're golden brown and crunchy. Serve them hot with a garlic aioli or spicy chipotle mayo.
