Prep the Air Fryer: Spray the basket with a thin layer of avocado oil.
Load the Fries: Place frozen sweet potato fries in a single layer in the air fryer basket. Avoid overcrowding for even crisping. (For a 6-quart air fryer, separate into two 0.5 lb / 285 g batches.)
Cook (First Round): Air fry at 400°F (200°C) for 6 minutes.
Shake & Flip: Remove the basket, let it sit for 10 seconds to release moisture, then shake vigorously or flip fries with a spatula.
Cook (Second Round): Air fry for another 2 minutes at 400°F (200°C), or until crisp but not burnt.
Repeat: Cook the remaining batch following the same steps.
Serve: Transfer hot fries to a serving plate, season with salt if needed, and enjoy plain or with your favorite dipping sauce.
Notes
Converting Oven Instructions: Reduce oven temperature by 25% and halve the minimum cooking time when converting to air fryer settings.
Example: If oven instructions recommend 425°F (220°C) for 12-24 minutes, air fry at 400°F (200°C) for about 6 minutes to start.
For Perfectly Crispy Fries: Always cook in batches to avoid overcrowding. Lay the fries in a single layer with minimal overlapping for the best texture. Air fryers work by circulating hot air in a small, confined space. As food cooks, it releases moisture, so to achieve the crispiest results, avoid overloading the basket.
Store-bought frozen sweet potato fries are pre-coated with oil during manufacturing, so there’s no need to spray additional oil on top. A light spritz in the basket is enough to prevent sticking.
Reheat leftovers at 360°F (182°C) for 4 to 5 minutes.
