Preheat the air fryer to 400°F (200°C) for 3–5 minutes. A hot basket jump-starts crisping and prevents sogginess.
Mix your seasoning. In a small bowl, combine 1 teaspoon kosher salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/2 teaspoon paprika. Adjust to taste.
Add fries to the basket in a single, loose layer. Avoid packing them tightly.For shoestrings, aim for no more than half-full. Work in batches if needed. Lightly spray with oil. One quick, even spritz is enough. Don’t drench—too much oil softens the crust.
Air fry for 6 minutes. Then pull out the basket, shake well, and sprinkle on about half of your seasoning.
Return to the air fryer for another 4–8 minutes. Shake once more midway.Total time depends on cut: shoestring (10–12 minutes), crinkle or waffle (12–15 minutes), steak fries (14–16 minutes). Season and finish. When the fries are golden and crisp, toss with the remaining seasoning. For a gourmet touch, add a small sprinkle of Parmesan and chopped parsley while hot.
Serve immediately. Fries are at their best within minutes of cooking. Pair with ketchup, aioli, or your favorite dipping sauce.
