01 - Peel the potatoes if desired, then cut into 1/4-inch thick sticks. Keep pieces uniform for even cooking.
02 - Submerge cut potatoes in a large bowl of cold water for at least 30 minutes. This step prevents sticking and ensures crispiness.
03 - Drain potatoes and pat completely dry with clean kitchen towels. Any remaining moisture will prevent proper crisping.
04 - In a large bowl, combine dried potatoes with olive oil, sea salt, black pepper, and garlic powder. Toss until evenly coated.
05 - Set air fryer to 380°F and preheat for 3 minutes before cooking.
06 - Place fries in a single layer in the air fryer basket. Work in batches if needed—overcrowding leads to soggy fries.
07 - Cook for 18-22 minutes, shaking the basket halfway through. Fries should be golden brown and crispy when done.
08 - Taste fries and sprinkle with additional sea salt if desired. Serve immediately while hot and crispy.
