Make perfectly crispy air fryer french fries with a fluffy interior using minimal oil. This easy recipe includes techniques for maximum crunch, whether you start with fresh potatoes or frozen ones.
Prepare Potatoes (Scratch Method): Peel the potatoes if desired, then cut them into uniform 1/4-inch thick sticks. Place the cut potatoes in a large bowl and cover completely with cold water. Soak for at least 30 minutes, or up to 2 hours, to remove excess starch.
Dry Thoroughly: Drain the potatoes completely. Lay them out on a clean kitchen towel or several layers of paper towels. Pat them completely dry. Moisture prevents crisping.
Season: Place the dry potatoes in a clean bowl. Drizzle with 1 tablespoon of oil and toss to coat lightly. Sprinkle with salt and pepper. If using, add garlic powder or Parmesan cheese now.
Preheat Air Fryer: Preheat your air fryer to 380°F (195°C) for 5 minutes.
Cook (Scratch Fries): Place the seasoned potatoes in the air fryer basket in a single layer, working in batches if necessary. Do not overcrowd the basket. Cook for 15 to 20 minutes, shaking the basket vigorously every 5 to 7 minutes to promote even browning and crisping.
Cook (Frozen Fries Hack): If using frozen fries, skip the soaking and drying steps. Place frozen fries in the basket without overcrowding. Cook at 400°F (200°C) for 10 to 14 minutes, shaking halfway through, until golden brown and crisp.
Check for Doneness: The fries are done when they are golden brown and crispy on the outside. If they are not crisp enough, increase the temperature to 400°F (200°C) and cook for an additional 2 to 3 minutes.
Serve Immediately: Remove the fries and transfer them to a serving bowl. Taste and add more salt if needed. Serve right away for the best texture.
Notes
Soaking potatoes is the key technique for achieving a fluffy interior and crispy exterior when making fries from scratch.
Do not skip drying the potatoes after soaking; this step is critical for crispiness.
For restaurant style air fryer fries, use Russet potatoes, as they have the right starch content.
If you want extra crispiness, toss the fries with 1 teaspoon of cornstarch after oiling them before the first cook cycle.
